Synthesis and biological evaluation of benzochromenopyrimidinones as cholinesterase inhibitors and potent antioxidant, non-hepatotoxic agents for Alzheimer's disease

Abstrakt

We report herein the straightforward two-step synthesis and biological assessment of novel racemic benzochromenopyrimidinones as non-hepatotoxic, acetylcholinesterase inhibitors with antioxidative properties. Among them, compound 3Bb displayed a mixed-type inhibition of human acetylcholinesterase (IC50 = 1.28 +/- 0.03 mu M), good antioxidant activity, and also proved to be non-hepatotoxic on human HepG2 cell line.
