Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Journal of Asian Natural Products Research called Design and synthesis of 7-diethylaminocoumarin-based 1,3,4-oxadiazole derivatives with anti-acetylcholinesterase activities, Author is Yu, Xiang; Zhao, You-Fang; Huang, Guo-Juan; Chen, Ya-Fang, which mentions a compound: 3326-71-4, SMILESS is O=C(C1=CC=CO1)NN, Molecular C5H6N2O2, Category: benzisoxazole.
Twelve novel 7-diethylaminocoumarin-based 1,3,4-oxadiazole derivatives I [R = n-Bu, 2-thienyl, Ph, etc.] were synthesized via iodine-mediated oxidative cyclization and confirmed by 1H NMR, 13C NMR and HRMS. The synthesized derivatives I were tested against in-vitro acetylcholinesterase inhibitory activity and results showed that compounds I [R = 4-ClC6H4, 4-BrC6H4] exhibited moderate inhibitory activities with 69.19% and 65.06%, resp. The preliminary structure-activity relationships revealed that introduction of halogen atom on the para-position of Ph of compounds I could enhance their activities. Mol. docking study suggested that compound I [R = ClC6H4] possessed an optimal docking pose with interactions inside AChE.
