Docking Energy

Stroke is the leading cause of disability and death worldwide. Inhibition of sulfonylurea 1 receptor (SUR1) using glibenclamide previously has been studied in CNS ischemic tissues and faster recovery from stroke injury in different animal models of stroke. Unfortunately, glibenclamide cannot enter the brain through an intact brain membrane (BBB) due to its ionization at physiological pH. Therefore, it was hypothesized that compounds with structural properties similar to glibenclamide but with the ability to penetrate through BBB would be superior to glibenclamide in ischemic stroke. Docking energy and interactions of glibenclamide with SUR1 active site were assessed using AutoDock Vina. NCI databases search engines with limitations for penetration to CNS were used to find the best compounds with desired properties. Then two selected compounds were assessed with dynamic molecular studies. Two compounds called CID-415537 and CID-419074 with docking energies of -10.3 kcal/mol and -11 kcal/mol were identified. CID-415537 was selected as the best compound due to its proper interactions with SUR1 amino acids and stability in molecular dynamic simulation. Based on this study, compound CID-415537 would be a good candidate for a SUR1 inhibitor in ischemic stroke. However, further in vivo investigations are required to confirm these findings.

The Impact

The myostatin (MSTN) is a known negative growth regulator of skeletal muscle. The mutated myostatin showed a double-muscular phenotype having a positive significance for the farmed animals. Consequently, adequate information is not available in the teleosts, including farmed rohu carp,Labeo rohita. In the absence of experimental evidence, computational algorithms were utilized in predicting the impact of point mutation of rohu myostatin, especially its structural and functional relationships. The four mutations were generated at different positions (p.D76A, p.Q204P, p.C312Y, and p.D313A) of MSTN protein of rohu. The impacts of each mutant were analyzed using SIFT, I-Mutant 2.0, PANTHER, and PROVEAN, wherein two substitutions (p.D76A and p.Q204P) were predicted as deleterious. The comparative structural analysis of each mutant protein with the native was explored using 3D modeling as well as molecular-dynamic simulation techniques. The simulation showed altered dynamic behaviors concerning RMSD and RMSF, for either p.D76A or p.Q204P substitution, when compared with the native counterpart. Interestingly, incorporated two mutations imposed a significant negative impact on protein structure and stability. The present study provided the first-hand information in identifying possible amino acids, where mutations could be incorporated into MSTN gene of rohu carp including other carps for undertaking furtherin vivostudies.
