Summary:
Novel 4-piperidone derivatives 2a–f are disclosed as potent cytotoxins. Many of these compounds are more potent than the reference drug melphalan. The compounds in series 2, 4–7 display selective toxicities toward various neoplasms compared to some normal cells. 2a is one of the promising lead molecules that display >11-fold higher growth inhibiting potency than 5-fluorouracil against human colon cancer cells. 2a induces apoptosis, DNA fragmentation, and cleavage of poly ADP-ribose polymerase.
