The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2-Furoic hydrazide( cas:3326-71-4 ) is researched.Name: 2-Furoic hydrazide.Yu, Xiang; Yang, Wude; Huang, Ling; Zhou, Xingji; Chen, Yafang published the article 《Preparation and acetylcholinesterase inhibitory activities of pyridine-based 1,3,4-oxadiazole derivatives》 about this compound( cas:3326-71-4 ) in Heterocycles. Keywords: pyridinyl oxadiazole preparation acetylcholinesterase inhibition SAR docking. Let’s learn more about this compound (cas:3326-71-4).
Fourteen pyridine-based 1,3,4-oxadiazole derivatives I [R = n-Bu, Ph, 3-pyridyl, etc.] were synthesized from pyridine-2-carboxaldehyde via iodine-mediated oxidative cyclization with substituted hydrazides by using the impregnation method. Their structures were confirmed by m.p., 1H NMR, 13C NMR and HRMS. Preliminary bioassay of these derivatives I, inhibition of acetylcholinesterase (AChE) was also evaluated in-vitro at the concentration of 1μmol/mL. The result showed that compounds I [R = 3-methoxyphenyl, 3-pyridyl, 4-pyridyl] had moderate inhibitory activities with 52%, 59% and 59%, resp. The preliminary structure-activity relationships revealed that the introduction of pyridine ring could enhance the activity. Mol. docking study demonstrated that compound I [R = 4-pyridyl] possessed an optimal docking pose with interactions at the middle of the catalytic active site (CAS) and peripheral anionic site (PAS) of AChE.
In some applications, this compound(3326-71-4)Name: 2-Furoic hydrazide is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
