Abstract

A series of new cinnamido-pyrrolo[2,1-c][1,4]benzodiazepine conjugates (4a-d and 5a-d) and their dimers (6a-d) have been designed, synthesized and evaluated for their biological activity. The anticancer screening of compound 4a by the NCI exhibited significant GI50 values ranging from 68 to 732 nM against 53 of 59 human cancer cell lines tested. Compounds 5a-d and 6a-d have also shown remarkable cytotoxic activity with GI50 values <0.1 microM concentrations in a large number of cell lines. Interestingly, compounds 5b and 6b have been identified as a new class of inhibitors of tubulin polymerization and their action has been rationalized by the cell cycle arrest in G0 and G2/M phase.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
