Abstract

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. © 2021 by the authors.
