Cholinesterase inhibitor plays an important role in the treatment of patients with Alzheimer’s disease (AD). Herein, we report the medicinal chem. efforts leading to a new series of 1,3-dimethylbenzimidazolinone derivatives Among the synthesized compounds, and showed submicromolar IC50 values (, eeAChE IC50 = 0.39 ± 0.11μM; , eqBChE IC50 = 0.16 ± 0.04μM) towards acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Kinetic and mol. modeling studies revealed that and act in a competitive manner. and showed neuroprotective effect against H2O2-induced oxidative damage on PC12 cells. This effect was further supported by their antioxidant activity determined in a DPPH assay in vitro. Morris water maze test confirmed the memory amelioration effect of the two compounds in a scopolamine-induced mouse model. Moreover, the hepatotoxicity of and was lower than tacrine. In summary, these data suggest and are promising multifunctional agents against AD. The results came from multiple reactions, including the reaction of Piperidine-4-carboxamide(cas: 39546-32-2Recommanded Product: 39546-32-2)
Piperidine-4-carboxamide(cas: 39546-32-2) belongs to anime. The reaction of alkyl halides, R―X, where X is a halogen, or analogous reagents with ammonia (or amines) is useful with certain compounds. Not all alkyl halides are effective reagents; the reaction is sluggish with secondary alkyl groups and fails with tertiary ones. Its usefulness is largely confined to primary alkyl halides (those having two hydrogen atoms on the reacting site).Recommanded Product: 39546-32-2
