RESUMO

In the current industrial scenario, cadmium (Cd) as a metal is of great importance but poses a major threat to the ecosystem. However, the role of micronutrient - amino chelates such as iron - lysine (Fe - lys) in reducing Cr toxicity in crop plants was recently introduced. In the current experiment, the exogenous applications of Fe - lys i.e., 0 and10 mg L - 1, were examined, using an in vivo approach that involved plant growth and biomass, photosynthetic pigments, oxidative stress indicators and antioxidant response, sugar and osmolytes under the soil contaminated with varying levels of Cd i.e., 0, 50 and 100 µM using two different varieties of canola i.e., Sarbaz and Pea - 09. Results revealed that the increasing levels of Cd in the soil decreased plant growth and growth-related attributes and photosynthetic apparatus and also the soluble protein and soluble sugar. In contrast, the addition of different levels of Cd in the soil significantly increased the contents of malondialdehyde (MDA) and hydrogen peroxide (H2O2), which induced oxidative damage in both varieties of canola i.e., Sarbaz and Pea - 09. However, canola plants increased the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and non-enzymatic compounds such as phenolic, flavonoid, proline, and anthocyanin, which scavenge the over-production of reactive oxygen species (ROS). Cd toxicity can be overcome by the supplementation of Fe - lys, which significantly increased plant growth and biomass, improved photosynthetic machinery and sugar contents, and increased the activities of different antioxidative enzymes, even in the plants grown under different levels of Cd in the soil. Research findings, therefore, suggested that the Fe - lys application can ameliorate Cd toxicity in canola and result in improved plant growth and composition under metal stress.

RESUMO

With a prevalence rate of 6.6 per 100,000 women, ovarian cancer is the third most lethal gynecological tumor in the world. Several factors like family history, nulliparity, late menopause, genetic mutation, and an unhealthy lifestyle contribute to increasing the risk of ovarian cancer development. Novel research studies suggest that ovarian cancer may be caused by changes in the lipid metabolic profile that trigger inflammatory responses. Moreover, ovarian cancer patients will eventually experience chemoresistance. Statin, a competitive inhibitor of HMG-CoA reductase that is a lipid-lowering drug with pleiotropic effects, seems to be the best choice to deal with this therapeutic issue. The aim of this review is to highlight the pharmacotherapeutic potential of statins, especially the repurposing of statin drugs for antitumor mechanisms. This review will also provide a brief summary of the meta-analysis, and case-control observational studies carried out to examine the impact of statins on risk reduction and survival in ovarian cancer patients. Furthermore, this review will discuss the nanotechnological approach for improving the drug's bioavailability and safe and targeted delivery with controlled release of active ingredients, making statins more effective in preventing and treating ovarian cancer.

RESUMO

Simmons-Smith cyclopropanation is a widely used reaction in organic synthesis for stereospecific conversion of alkenes into cyclopropane. The utility of this reaction can be realized by the fact that the cyclopropane motif is a privileged synthetic intermediate and a core structural unit of many biologically active natural compounds such as terpenoids, alkaloids, nucleosides, amino acids, fatty acids, polyketides and drugs. The modified form of Simmons-Smith cyclopropanation involves the employment of Et2Zn and CH2I2 (Furukawa reagent) toward the total synthesis of a variety of structurally complex natural products that possess broad range of biological activities including anticancer, antimicrobial and antiviral activities. This review aims to provide an intriguing glimpse of the Furukawa-modified Simmons-Smith cyclopropanation, within the year range of 2005 to 2022.

RESUMO

Soil contamination with toxic heavy metals (such as arsenic (As)) is becoming a serious global problem due to rapid development of social economy, although the use of silicon (Si) and sodium hydrosulfide (NaHS) has been found effective in enhancing plant tolerance against biotic and abiotic stresses including the As toxicity. For this purpose, a pot experiment was conducted using the different levels of As toxicity in the soil, i.e., (0 mM (no As), 50, and 100 µM) which were also supplied with the different exogenous levels of Si, i.e., (0 (no Si), 1.5, and 3 mM) and also with the NaHS, i.e., (0 (no NaHS), 1, and 2 mM) on growth, photosynthetic pigments, gas exchange characteristics, oxidative stress biomarkers, antioxidant machinery (enzymatic and non-enzymatic antioxidants), and their gene expression, ion uptake, organic acid exudation, and As uptake of maize (Zea mays L.). Results from the present study showed that the increasing levels of As in the soil significantly (P < 0.05) decreased plant growth and biomass, photosynthetic pigments, gas exchange attributes, sugars, and nutritional contents from the roots and shoots of the plants. In contrast, increasing levels of As in the soil significantly (P < 0.05) increased oxidative stress indicators in terms of malondialdehyde, hydrogen peroxide, and electrolyte leakage and also increased organic acid exudation patter in the roots of Z. mays, although the activities of enzymatic antioxidants and the response of their gene expressions in the roots and shoots of the plants and non-enzymatic such as phenolic, flavonoid, ascorbic acid, and anthocyanin contents were initially increased with the exposure of 50 µM As, but decreased by the increasing the As concentration 100 µM in the soil. The negative impact of As toxicity can overcome the application of Si and NaHS, which ultimately increased plant growth and biomass by capturing the reactive oxygen species and decreased oxidative stress in Z. mays by decreasing the As contents in the roots and shoots of the plants. Our results also showed that the Si was more sever and showed better results when we compared with NaHS under the same treatment of As in the soil. Research findings, therefore, suggest that the combined application of Si and NaHS can ameliorate As toxicity in Z. mays, resulting in improved plant growth and composition under metal stress, as depicted by balanced exudation of organic acids.

RESUMO

The main intention in the modern era is to make life and activities on earth more comfortable by adding necessary products through biological machinery. Millions of tons of biological raw materials and lignocellulosic biomass are wasted by burning each year without providing benefits to living organisms. Instead of being the cause of disturbing the natural environment by increasing global warming and pollutants worldwide, now, it is the need of the hour to develop an advanced strategy to utilize these biological raw materials to produce renewable energy resources to meet the energy crisis. The review presents the idea of multiple enzymes in one step to hydrolyze complex biomaterials into useful products. The paper discusses how multiple enzymes are arranged in a cascade for complete hydrolysis of raw material in one-pot to prevent multistep, time consuming, and expensive methods. Furthermore, there was the immobilization of multiple enzymes in a cascade system with in vitro and in vivo conditions for reusability of enzymes. The role of genetic engineering, metabolic engineering, and random mutation techniques is described for the development of multiple enzyme cascades. Techniques that are involved in the improvement of native strain to recombinant strain for the enhancement of hydrolytic capacity were used. The preparative steps, before enzymatic hydrolysis like acid, and base treatment methods are more effective for improving the hydrolysis of biomass by multiple enzymes in a one-pot system. Finally, the applications of one-pot multienzyme complexes in biofuel production from lignocellulosic biomass, biosensor production, medicine, food industry, and the conversion of biopolymers into useful products are described.

RESUMO

Human tyrosinase (hTYR) is a key and rate-limiting enzyme along with human tyrosinase-related protein-1 (hTYRP1), which are among the most prominent targets of inhibiting hyper pigmentation and melanoma skin cancer. In the current in-silico computer-aided drug design (CADD) study, the structure-based screening of sixteen furan-1,3,4-oxadiazole tethered N-phenylacetamide structural motifs BF1-BF16 was carried out to assess their potential as hTYR and hTYRP1 inhibitors. The results revealed that the structural motifs BF1-BF16 showed higher binding affinities towards hTYR and hTYRP1 than the standard inhibitor kojic acid. The most bioactive lead furan-1,3,4-oxadiazoles BF4 and BF5 displayed stronger binding in affinities (-11.50 kcal/mol and -13.30 kcal/mol) than the standard drug kojic acid against hTYRP1 and hTYR enzymes, respectively. These were further confirmed by MM-GBSA and MM-PBSA binding energy computations. The stability studies involving the molecular dynamics simulations also provided stability insights into the binding of these compounds with the target enzymes, wherein it was found that they remain stable in the active sites during the 100 ns virtual simulation time. Moreover, the ADMET, as well as the medicinal properties of these novel furan-1,3,4-oxadiazole tethered N-phenylacetamide structural hybrids, also showed a good prospect. The excellent in-silico profiling of furan-1,3,4--oxadiazole structural motifs BF4 and BF5 provide a hypothetical gateway to use these compounds as potential hTYRP1 and hTYR inhibitors against melanogenesis.

RESUMO

Cadmium toxicity is one of the deleterious abiotic factors that reduce wheat production. Two different cultivars (Akbar and Dilkash) were compared for their cadmium (0, 40 and 80 mg/kg) tolerance and responses towards Bacillus subtilis NA2, Aspergillus niger PMI-118 and L-proline. Both microbes were tested for heavy metal tolerance and production of various plant hormones and biological active enzyme characteristics under normal and cadmium stress. A completely randomized design (two cultivars × four treatments × three cadmium levels × three replicates) was adopted using distilled water as a control. The growth promotion potential of these strains under cadmium stress was determined by N-fixation, IAA synthesis, P-solubilization, amylase and proteases production. A pot experiment under controlled conditions was conducted to evaluate the effect of bacteria, fungi, and L-proline under cadmium stress. It was indicated from the result that plant biomass (46.43%), shoot length (22.40%), root length (25.06%), chlorophyll (17.17%), total sugars (27.07%), total proteins (86.01%) and ascorbic acid (83.27%) were improved with inoculation under control and cadmium stress. The accumulation of total flavonoids (48.64%), total phenolics (24.88%), hydrogen peroxide (53.96%) and activities of antioxidant enzymes CAT (26.37%) and APX (43.71%) were reduced in the plants treated with bacteria, fungi and L-proline than those under control. With parallel aids, Bacillus subtilis NA2 showed a higher cadmium tolerance and plant growth stability as compared to Aspergillus niger PMI-118 and L-proline and may be adopted in the future.

RESUMO

The Mitsunobu reaction plays a vital part in organic chemistry due to its wide synthetic applications. It is considered as a significant reaction for the interconversion of one functional group (alcohol) to another (ester) in the presence of oxidizing agents (azodicarboxylates) and reducing agents (phosphines). It is a renowned stereoselective reaction which inverts the stereochemical configuration of end products. One of the most important applications of the Mitsunobu reaction is its role in the synthesis of natural products. This review article will focus on the contribution of the Mitsunobu reaction towards the total synthesis of natural products, highlighting their biological potential during recent years.

RESUMO

Heavy metal contamination of the cosmetic products poses potential harm for consumers' health. We aimed to determine the concentration of Arsenic (As), Lead (Pb), and Cadmium (Cd) in locally available colored cosmetics such as lipsticks, foundation cream, facial powder, and eye shadows. We determined concentration of As, Pb, and Cd in 40 samples of colored cosmetics by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and determined significant differences in As and Cd concentrations across the colored cosmetics. We detected a high concentration of Pb and As in lipstick and eye shadow samples. Concentration of Pb and Cd in the samples of foundation creams was at safe level. Most of the cosmetic samples contained heavy metals above safe levels posing a threat to the health of female consumers who use them for long periods. Regulatory bodies in Pakistan must adopt and enforce international standards for colored cosmetics.

RESUMO

Direct dyes are used in different textile operations and processings. The textile industries are disposing of unused direct dyes into the aquatic environment which is posing a serious alarming threat to aquatic lives. The current study deals with the synthesis of nickel oxide nanoparticles using Allium cepa peels aqueous extract. Nickel oxide nanoparticles (NiO-NPs) were characterized by scanning electron microscopy (SEM). Synthesized NiO-NPs were used to remove Congo red direct dye. Various experimental factors like concentration of dye and nanoparticles, pH, and temperature were optimized. Congo red direct dye was decolorized up to 90% at optimized conditions (Congo Red Direct dye concentration 0.02%, catalyst dose 0.003 g·L-1, pH 6, and temperature 50 °C). The real textile industry effluent disclosed 70% decolorization at optimized conditions. The percent reduction in total organic carbon (TOC) and chemical oxygen demand (COD) was found to be 73.24% and 74.56% in the case of Congo red dye catalytic treatment and the percent reduction in TOC and COD was found to be 62.47% and 60.23%, respectively, in the treatment of textile effluent using nickel oxide nanoparticles as a catalyst. Treated and untreated dye samples were exposed to Fourier transform infrared (FTIR) and UV-Visible spectral analyses too. The reaction products were studied by degradation pathway.

RESUMO

Chromium stress is one of the deleterious abiotic factors that reduce crop production. Two anatomically different crops (C3 and C4) were compared for their chromium (0 and 50 ppm) tolerance and responses towards Bacillus subtilis (B. subtilis). Strains of B. subtilis were exposed to UV (30-210 min) and gamma irradiation (1-4 KGy), and the best mutants were selected on petri plates containing selective markers. Maize and mungbean were supplied with selected strains or the parent strain in rooting medium, along with a nutrient broth. A completely randomized design (five replicates) was adopted using nutrient broth as a control. Stress negatively affected plants grown without strains. Mungbean was more sensitive towards stress and treatments, maize had better root and shoot fresh weights, root and shoot lengths, proline levels, and MDA and GR activity. All strains of B. subtilis (parent, γ-irradiated and UV-irradiated) enhanced proline, total soluble protein, chlorophyll a, a + b and a/b levels, with negligible effects upon antioxidant enzymes. Irradiated strains proved their superiority to the parent strain, with reductions in H2O2 and MDA content. With comparable benefits, γ and UV irradiation may be adopted in future based upon technical availability.

RESUMO

OBJECTIVE: To evaluate the effect of cookies supplemented with apple pomace and mango-peel powder on postprandial glucose and insulin concentration. METHODS: The experimental study was conducted from February to August, 2018, at the Nutrition Counselling Centre, Government College Women University, Faisalabad, Pakistan. Different cookies with apple pomace and mango-peel powder were prepared and the most nutritive acceptable cookies were used to determine their postprandial effect on glucose and insulin concentrations against the control cookies made with white flour only in female subjects. Adult women were selected through advertisement with normal body mass index. Data was analysed using SPSS 17. RESULTS: All the 30 subjects received enriched and control cookies at different time slots during the study. The overall mean age of the sample was 25±10 years and each subject had body mass index <25kg/m2. Overall blood glucose and insulin concentrations were significantly lower with treatment cookies , compared to the control cookies (p<0.05). CONCLUSIONS: It was evident that fruit processing waste can be used as a nutraceutical agent in diet-based modules.

RESUMO

The aim of this project was to improve the Aspergillus terreus strain and pretreatment of sugarcane bagasse as carrier substrate for bulk production of lovastatin, a cholesterol-lowering drug, in solid state fermentation. Sugarcane bagasse was treated with alkali (1-3% NaOH) for the conversion of complex polysaccharides into simple sugars for better utilization of carrier substrate by microorganism for maximum lovastatin production. Ethidium bromide (time of exposure 30-180 min) was used to induce mutation in Aspergillus terreus and the best mutant was selected on the basis of inhibition zone appeared on petri plates. Fermented lovastatin was quantified by high-performance liquid chromatography. The fermented lovastatin, produced by parent and mutant Aspergillus terreus strain, was checked on body weight, blood glucose and serum cholesterol, ALT, AST, HDL-C, LDL-C, TG and TC levels of rats for their cholesterol lowering capacity. Our results indicate that selected strain along with 2% NaOH treated sugar cane bagasse was best suitable for bulk production of lovastatin by fermentation and fermented lovastatin effectively lower the cholesterol level of rats.

RESUMO

Priming is a valuable, facile and well-established technique used to enhance seed quality to achieve rapid germination, establishment of stress resistance and improvement of crop yields. Different natural and synthetic priming agents have been used for better crop performance and abiotic stress management. In this study, four different benzimidazoles were selected as priming agents and their comparative effects were evaluated on different biochemical attributes including total soluble protein, total oxidant status, MDA contents, antioxidant enzymes (SOD, POD) and hydrolytic enzymes (protease, estrases) compared to control. Treatments with 2-thio-1-H-benzimidazole reduced total soluble proteins and increased total oxidant status significantly but no considerable effect was observed on other parameters. Priming with 2-(4-chlorophenyl)-1-H-benzimidazole considerably increased the total oxidant status and a little improvement was observed in total soluble proteins. Seeds primed with 1-H-benzimidazole showed a noticeable decrease in the protease activity while all other priming treatments were unable to induce any detectable change compared to control. The treatment with 2-(4-methoxyphenyl)-1-H-benzimidazole induced maximum reduction in MDA contents and POD activity. Moreover, all benzimidazole priming treatments reduced mean germination time, increased germination percentage and germination rate of wheat seeds.

RESUMO

AIM AND OBJECTIVE: Reactive dye molecules are commonly employed to dye or modify colour characteristics of wool fibres. Yellowness of wool fibres poses a challenge and here, we report synthesis of a reactive fluorescent molecule and its application to wool fibres to reduce yellowness of the wool fibre and improve its colour features. MATERIAL AND METHODS: The new molecule was based upon 7-amino-4-methylcoumarin (AMC) and 2,4,6- trichloro-1,3,5-triazine (TZT). The synthesis involved a two-step chemical reaction, initiated by the nucleophilic substitution of a chloro group on the triazine ring with the hydroxyl group of 4-hydroxybenzenesulfonic acid. The substitution of 2nd chloro group at triazine ring with the amino group of 7-amino-4-methylcoumarin resulted in a novel molecule with a monofunctional reactive chloro group (AMC-MCT molecule). RESULTS: The new molecule was applied to the wool fibres using exhaust dyeing method. This exhibited a high exhaustion value; however low fixation and total efficiency values were observed for the new molecule. The resultant wool fibres exhibited fluorescence which shows that aminocoumarin fluorophore retained its fluorescence when incorporated in the new molecule. An assessment of the molecule for yellowness index in a controlled exposure to UV radiation suggested an improvement in whiteness of wool fibre. CONCLUSION: A novel aminocoumarin based fluorescent whitening molecule 2 has been synthesised and applied to the wool fibres. The new molecule continued to exhibit fluorescence after its application to the wool fibres. These results will encourage researchers to explore further possibilities for reactive whitening agent for wool fibres.

RESUMO

BACKGROUND: The chief aim of this study was to enlist the ethnobotanical uses of wild plants in district Sheikhupura, province Punjab, Pakistan. Due to extreme geographical and climatic conditions, Pakistan has a great floral diversity. Plants have been used by the indigenous people for treatment of different ailments since long. They are still dependent on the plants for their domestic purposes. Moreover, plants are used as first aid to treat diverse ailments such as cold, cough, influenza, asthma, cancer, antidote, gastric and hepatic disorders. The traditional uses of medicinal plants lead to the discovery of natural drugs. This is first quantitative ethnobotanical documentation of medicinal plants in NavaPind and ShahpurVirkan district Sheikhupura, province Punjab, Pakistan. METHODS: This ethnobotanical information was collected from about 400 informants including male and female. Sample size was determined by statistical formula. The informative data was based on semi-structured interviews, group discussions, Questionnaire and field visits. Then the data was analyzed by applying different quantitative indices such as Informant Consent Factor (ICF), Use value (UV), Relative Frequency of Citation (RFC), the Fidelity level (FL) and Jaccard Index (JI). RESULTS: Almost 96 plants belonging to 34 families were reported. Most-frequently cited families were Poaceae (16 species) and Fabaceae (15 species). The most dominant life form was herbs (30.20%). The most-used plant parts were leaves (31.14%), followed by whole plant (24.59%), Most common mode of administration is extraction (81.25%). Generally herbal medicines were acquired from fresh plant material. Among all 54.16% plants were toxic, 31.25% were nontoxic, whereas the remaining 14.58% may be toxic or nontoxic because of their dual attitude. Almost 34 species were reported with their different medicinal uses as has been reported in literature. CONCLUSIONS: This ethnobotanical documentation revealed that the plants are still used by natives of rural areas in their day-to-day lives. This study provides basis for the conservation of local flora. Plants with high ICF, UV and FL can be further used for phytochemical and pharmacological studies. This documentation could provide baseline information which can be used to develop new plant-based commercial drugs.

RESUMO

BACKGROUND/AIM: Biochemical, environmental, and genetic factors such as oxidative stress-induced DNA damage and homocysteine (Hcy) accumulation in the blood are involved in the development and progression of ovarian cancer. This study measured some biomarkers closely linked to the progression of ovarian cancer and also found their correlates. MATERIALS AND METHODS: Thirty patients were diagnosed with ovarian cancer using pelvic examination, transvaginal ultrasound, and cancer antibody (CA-125) measurement. Total oxidative stress (TOS), DNA damage, Hcy, malondialdehyde (MDA), total antioxidant status (TAS), and other biochemical parameters were determined. RESULTS: TOS and DNA damage were positively and significantly correlated between themselves and were involved in causation of tumors as reflected by significantly (P < 0.001) higher CA-125, erythrocyte sedimentation rate (ESR), creatinine, and C-reactive protein (CRP) in both young and old patients. Both were significantly correlated with Hcy, LDL-cholesterol, alanine aminotransferase, aspartate aminotransferase, CRP, MDA, and CA-125. However, they were negatively correlated with TAS. Thus, excessive inflammation and oxidative stress caused an increase in DNA damage and enhanced Hcy content, leading to development of ovarian cancer. CONCLUSION: This study suggests the use of antioxidants as drugs to reduce oxidative stress, DNA damage, and other causes of cancer development.

RESUMO

This project was planned to study the production of cholesterol lowering drug mevastatin by Aspergillus terreus GCBL-03 on pretreated substrate bagasse in solid state fermentation. Bagasse was pretreated by potassium hydroxide to delignify the substrate to readily become available to microorganism. It was noticed that pretreated bagasse exhibited 13.69±0.64 mg/100mL yield of mevastatin and 6.63±0.48 g dry cell mass as compared to nontreated substrate that showed 7.04±0.81 mg/100 mL and 6.04±0.24 g dry cell mass. The fermentation profile like pH (5.5), temperature (30 °C), moisture contents (60%) inoculum size (2 mL), and incubation time (72 h) showed the optimum production (30.63±1.24 mg/100 mL) of mevastatin. Furthermore, fermented drug showed noteworthy antifungal activity against battery of selected fungal strains assessed by disc diffusion and measurement of minimum inhibitory concentration by micro dilution method. It was concluded from the study that fermented mevastatin was effective against fungal strains.

RESUMO

Amounts of DNA damage and homocysteine (Hcy) in heart patients blood may have strong function in the causation of cardiovascular disease (CVD). The main objective of this work was to know experimentally the role of total oxidants (produced by Reactive Oxygen species (ROS), clinical biochemical indices, their oxidized products and total antioxidant status (TAS) among such patients to find the association of homocysteine, total oxidation status (TOS) and oxidative DNA damage with other clinical parameters in sixty positive CVD patients compared with those of 60 normal subjects. As compared to healthy individuals, CVD patients had significantly higher concentrations of homocysteine (p<0.0001), total oxidants stress (TOS) (p<0.0001), serum total lipids (p<0.04), malondialdehyde (MDA) (p<0.001), high density lipoprotein-cholesterol (HDL-C) (p<0.0001), and low density lipoprotein cholesterol (LDL-C) (p<0.01), than those of healthy individuals. Plasma Hcy content, TOS and amount of DNA were positively and significantly associated with cholesterol, triglycerides, systolic blood pressure, urea, and albumin (p values<0.01). TOS, Hcy and oxidative DNA damage were negatively correlated with HDL-c, TAS and proteins. It is suggested that these parameters have pivotal role in diagnostic process of determining severity in CAD patients. Oxidized products of macromolecules in blood of CVD patients impart major functions in causing CVD disease.
