Molecular docking analysis of calcium channel blockers with ALR2 and RAGE.

A metabolic condition called diabetes mellitus is linked to a number of substantial challenges. Advanced Glycation End Products (AGEs) and Aldose reductase (ALR2) are crucial in the slow development of several secondary complications. Selected calcium channel blockers (CCB's-1, 4-dihydropyridines) were docked against ALR2 (PDB code: 1Z3N) and RAGE (PDB code: 3CJJ) in the current study. We report that 1, 4-dihydropyridine compounds, particularly Benidipine, bind to the active sites with good efficiency. Thus, 1,4 dihydropyridine derivatives can be considered for further confirmation in drug discovery.

Isolation, Molecular Identification and Amino Acid Profiling of Single-Cell-Protein-Producing Phototrophic Bacteria Isolated from Oil-Contaminated Soil Samples.

In the current study, soil samples were gathered from different places where petrol and diesel filling stations were located for isolation of photosynthetic bacteria under anaerobic conditions using the paraffin wax-overlay pour plate method with Biebl and Pfennig's medium. The three isolated strains were named Rhodopseudomonas palustris SMR 001 (Mallapur), Rhodopseudomonas palustris NR MPPR (Nacahram) and Rhodopseudomonas faecalis N Raju MPPR (Karolbagh). The morphologies of the bacteria were examined with a scanning electron microscope (SEM). The phylogenetic relationship between R. palustris strains was examined by means of 16S rRNA gene sequence analysis using NCBI-BLAST search and a phylogenetic tree. The sequenced data for R. palustris were deposited with the National Centre for Biotechnology Research (NCBI). The total amino acids produced by the isolated bacteria were determined by HPLC. A total of 14 amino acids and their derivatives were produced by the R. palustris SMR 001 strain. Among these, carnosine was found in the highest concentration (8553.2 ng/mL), followed by isoleucine (1818.044 ng/mL) and anserine (109.5 ng/mL), while R. palustris NR MPPR was found to produce 12 amino acids. Thirteen amino acids and their derivatives were found to be produced from R. faecalis N Raju MPPR, for which the concentration of carnosine (21601.056 ng/mL) was found to be the highest, followed by isoleucine (2032.6 ng/mL) and anserine (227.4 ng/mL). These microbes can be explored for the scaling up of the process, along with biohydrogen and single cell protein production.

Multi-targeting Andrographolide and its Natural Analogs as Potential Therapeutic Agents.

Andrographis paniculata (A. paniculata) is a medicinal plant used in the Indian and Chinese traditional medicinal systems for its various beneficial properties of therapeutics. This is due to the presence of a diterpene lactone called 'andrographolide'. Several biological activities like antiinflammatory, antitumour, anti-hyperglycaemic, anti-fertility, antiviral, cardio protective and hepatoprotective properties are attributed to andrographolide and its natural analogs. The studies have shown that not only this diterpene lactone (andrographolide), but also other related terpenoid analogs from A. paniculata could be exploited for disease prevention due to their structural similarity with diverse pharmacological activities. Several scientific groups are trying to unveil the underlying mechanisms involved in these biological actions brough aout by andrographolide and its analogs. This review aims at giving an overview on the therapeutical and/or pharmacological activities of andrographolide and its derivatives and also exemplify the underlying mechanisms involved.
