Abstract
In the present investigation we have synthesized novel substituted dienone pyridine ethanone curcumin analogues 3a and 3b by nucleophilic substitution reactions with 2-bromo-1-pyridine-3-yl ethanone and characterized by 1H nuclear magnetic resonance (NMR), infrared IR, mass, and CHNS analysis. The compounds demonstrated tumor growth inhibition and antiangiogenic effects against mouse Ehrlich ascites tumor in vivo and suppressed neovascularization in a chorio allantoic membrane model.
