Synthesis of novel curcumin mimics with asymmetrical units and their anti-angiogenic activity

Novel curcumin mimics with asymmetrical units phenyl group with alkyl amide, chloro-substituted benzamide, or heteroaromatic amide moieties were synthesized and their anti-angiogenic activity was evaluated with the proliferation and tube formation inhibitory activity on the human umbilical vein endothelial cells. Compounds 5, 14, 17, and 18 showed potent growth inhibitory activity and tube formation inhibitory activity.
