Abstract

C-Abl is involved in various biological processes and plays an important role in neurodegenerative diseases, especially Parkinson's disease (PD). Previous studies have found that nilotinib shows a neuroprotective effect in cell and animal models of PD by inhibiting the activation of c-Abl. But the low blood-brain barrier permeability and potential toxicity limit the further use of nilotinib in PD. Based on molecular modeling studies, a series of 4-methyl-3-(pyridin-2-ylamino)benzamide derivatives were designed and synthesized. In particular, compound 9a exhibited significant inhibitory activity against c-Abl and a potent neuroprotective effect against MPP+-induced SH-SY5Y cell death. Moreover, 9a not only displayed lower cell toxicity compared with nilotinib, but also showed higher oral bioavailability and proper permeability of the blood-brain barrier. This paper provides 4-methyl-3-(pyridin-2-ylamino)benzamide derivatives as a new scaffold for c-Abl inhibitor with potential neuroprotective effect.
