In this paper we report the synthesis, in‐silico and in‐vitro evaluations of a new series of benzothiazole linked triazole conjugates. The synthesized compounds have been evaluated as the inhibitor of cholinesterase enzymes using Ellman's method. The benzothiazole and triazole derivatives were synthesized separately and further combined through covalent amide bond linkage.The compounds showed good to excellent results towards butyryl cholinesterase (BuChE) inhibition. Docking studies revealed that the hydrophobic aromatic part of N‐benzothiazole binds to the PAS and the 1,2,4‐triazole residue binds to the CAS of BuChE. The in‐silico docking results for BuChE are consistent with the in‐vitro results. Also, the molecular dynamics simulation studies of the best docked molecule 8 a had shown similar binding stability as the reference drug donepezil. Good molecular interaction was also observed for acetylcholinesterase (AChE). The molecular modelling and evaluations against cholinesterase enzyme provided novel lead molecule which with further modifications in their structure have potential for the treatment of Alzheimer disease (AD) in future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
