Abstract

A series of novel hybrid structure derivatives, containing both LEE011 and Cabozantinib pharmacophore, were designed, synthesized and evaluated. Surprisingly, a compound 4d was discovered that highly exhibited effective and selective activity of CDK9 inhibition with IC50=12nM. It effectively induced Apoptosis in breast and lung Cancer cell lines at nanomolar level. Molecular docking of 4d to ATP binding site of CDK9 kinase demonstrated a new hydrogen bonding between F atom of 4-(3-fluorobenzyloxy) group and ASN116 residue, compared with the positive control, LEE011. The compound 4d could block the cell cycle both in G0/G1 and G2/M phase to prevent the proliferation and differentiation of Cancer cells. Mice bared-breast Cancer treated with compound 4d showed significant suppression of Cancer with low toxicity. Taken together, this novel compound 4d could be a promising drug candidate for clinical application.
