ABSTRACT
Diaper dermatitis is a common disorder. Coriandrum sativum is a herbal remedy with anti-inflammatory, analgesic, anti-microbial and anti-oxidant activities effects. In this nonrandomised clinical trial which was performed on 58 infants with diaper dermatitis referred to Faghihi Hospital, Shiraz University of Medical Sciences, the efficacy and safety of topical Coriandrum extract cream is compared with hydrocortisone ointment. Coriandrum sativum extract cream was administered for 37 (intervention group) and hydrocortisone 1% ointment for 21 (control group) patients. Patients were examined on days 3 and 10. Chi-square test was applied for statistical analysis. The results demonstrated a statistically significant difference in the cure rate (20 (54.1%) for the intervention group versus 19 (90.5%) for the control group) (P-value = 0.005) and side effects (10 (27%) for the intervention group versus 0 (0%) for control group) (P-value = 0.009) both in favor of hydrocortisone. This trial failed to confirm the efficacy of Coriandrum sativum in the treatment of diaper dermatitis; however, it seems that if soothing compounds are used in combination with Coriandrum sativum to reduce the mild irritation, Coriandrum extract can be an alternative treatment for diaper dermatitis.
ABSTRACT
Nitroimidazole derivatives such as Metronidazole [MTZ] have been used as anti- protozoa and anti-anaerobic bacteria. In this study several compounds of MTZ derivatives were synthesized and evaluated against Giardia lamblia cyst. Firs MTZ were reacted with several alkyl halide to obtain O-alkyl MTZ derivatives, then products were purified and their chemical structures were confirmed by elemental and spectral analysis [1HNMR and Mass]. In order to biological evaluation all compounds were investigated against 25 Giardia samples isolated from giarfdiasis patients. Results showed compound 2a had the most activity on cyst of Giardia in comparison with MTZ
ABSTRACT
Giardiasis is a protozoal infection of small intestine caused by giardia lamblia. The disease is usually asymptomatic though it can present as acute or chronic diarrhea. Giardiasis is a major cause of intestinal infection and Iran is an endemic area of the disease. Despite reports about drug resistance, long course treatment and various side effects, metronidazole is the drug of choice for giardiasis. In this study we investigated in vivo effects of five new derivatives [a-e] of metronidazole [MTZ] on the giardia lamblia trophozoite in infected mice. Giardia intestinalis cysts were isolated from a patient and purified by sucrose gradient method. Fifty Purified cysts were inoculated to mice and after development of infection, the new metronidazole derivatives were given to the mice and results were compared to metronidazole as positive control. Compounds a and b showed desirable antigiardiasis activity and could destroy the cyst and trophozoite of giardia lamblia in mice after both two and four days, but the activity of the other compounds appeared only after 4 days
ABSTRACT
4-Anilinoquinazolines have been widely studied as anticancer agents. Despite the widespread use of this class of compounds, the reported syntheses of 4-anilinoquinazolines require multistep and lowyielding reaction pathways. In this study, a novel strategy to prepare 4-anilinoquinazoline derivatives based on the cyclization of anthranilic acid is described. By using dichloroanthranilic acid, the quinazoline ring was etherified in order to mimic the erlotinib structure as a tyrosine kinase inhibitor. The new compounds contain different substitutions at the meta-positions of the quinazoline ring instead of the ortho-positions of erlotinib. Ten new 4-anilinoquinazoline derivatives were sysnthesized [21-30] in only 4 steps with desirable yield
