Abstract: | Synthesis of 14-deoxy-benzylidene-8,17-epoxy-diene-andrographolide derivatives from andrographolide and evaluation of their anticancer activities were described herein. 3,19 hydroxy groups of andrographolide were protected by benzylidene which undergo m-chloroperbenzoic acid mediated epoxydation in moderate yield to form corresponding epoxy derivatives. Thereafter mild basic condition was applied to perform de-hydroxylation at C-14 which resulted in conjugated diene derivatives of benzylidene epoxy andrographolide. These compounds were examined against different human cancer cell lines and were found to inhibit their proliferation at IC50 in the range of 3–20 μM in order to elucidated the role of allylic hydroxyl group at C-14. |
