Design, synthesis and bioevaluation of 1,2,3,9-tetrahydropyrrolo[2,1-b]quinazoline-1-carboxylic acid derivatives as potent neuroprotective agents
摘要:
Diverse of 1,2,3,9-tetrahydropyrrolo[2,1-b]quinazoline-1-carboxylic acid derivatives were designed, synthesized and evaluated for their neuroprotective activity against NMDA-induced cytotoxicity in vitro, and 5q exhibited excellent neuroprotective activity. The compound 5q was selected for further investigation. We found that 5q could attenuate Ca2+ influx induced by NMDA, meanwhile, Sq could suppress the NR2B up-regulation and increase p-ERK1/2 expression. The molecular docking results showed that 5q might fit well in the binding pocket of 4 and interact with some key residues in the binding pocket of 1 simultaneously. Besides, 5q exhibited acceptable metabolic stability. These results suggested that 5q was a promising lead for further development of new potent and orally bioavailable NR2B-selective NMDAR antagonists. (C) 2018 Elsevier Masson SAS. All rights reserved.
A series of novel (−)‐1,2,3,9‐tetrahydropyrrolo[2,1‐b]quinazoline‐1‐carboxylic acidderivatives were designed and synthesized. All of the prepared compounds were screened for their neuroprotective effects using an in vitro oxygen glucose deprivation (OGD) model of ischemic stroke. Some of the target compounds exhibited moderate to excellent protective potency. In particular, compounds 9d, 9e, 9g, and
