Abstract: Biphenyl-4-carboxylic acid-[2-(1H-indol-3-yl)-ethyl]-methylamide 1 (CA224) is a nonplanar analogue of fascaplysin (2) that specifically inhibits Cdk4-cyclin D1 in vitro. Compound 1 blocks the growth of cancer cells at G0/G1 phase of the cell cycle. It also blocks the cell cycle at G2/M phase, which is explained by the fact that it inhibits tubulin polymerization. Additionally, it acts as an enhancer of depolymerization for taxol-stabilized tubulin. Western blot analyses of p53-positive cancer cells treated with compound 1 indicated upregulation of p53, p21, and p27 proteins together with downregulation of cyclin B1 and Cdk1. Compound 1 selectively induces apoptosis of SV40 large T-antigen transformed cells and significantly reduces colony formation efficiency, in a dose-dependent manner, of lung cancer cells. It is efficacious at 1/10th of the MTD against human tumors derived from HCT-116 and NCI-H460 cells in SCID mouse models. The promising efficacy of compound 1 in human xenograft models as well as its excellent therapeutic window indicates its potential for clinical development.
