Disclosed herein are novel benzophenone derivatives represented by formula I, a pharmaceutically acceptable salt thereof, a hydrate thereof or a solvate thereof, a pharmacological composition containing the same, and a use of the composition as therapeutic drugs. The benzophenone derivatives have an inhibition activity of microtubule formation and can be used to treat a normal proliferative state of a malignant tumor by killing the actively proliferating cells.

Tubulin polymerization inhibitors had emerged as one of promising anticancer therapeutics because of their dual mechanism of action, i.e. apoptosis by cell-cycle arrest and VDA, vascular disrupting agent. VDAs are believed to be more efficient, less toxic, and several of them are currently undergoing clinical trials. To identify novel tubulin inhibitors that possess potent cytotoxicity and strong inhibition of tubulin polymerization as well as potent in vivo antitumor efficacy, we have utilized benzophenone scaffold. Complete SA R analysis of newly synthesized analogues that were prepared by incorporation of small heterocycles (C2, C4, and C5 position) into B-ring along with the evaluation of their in vitro cytotoxicity, tubulin polymerization inhibition, and in vivo antitumor activity allowed us to identify 22 (S516). Compound 22 was found to have potent cytotoxicity against several cancer cells including P-gp overexpressing MDR positive cell line (HCT15). It also induced cell cycle arrest at G(2)/M phase, which is associated with strong inhibition of tubulin polymerization. Its in vivo efficacy was improved by preparing its (L)-valine prodrug, 65 (CKD-516), which together with greatly improved aqueous solubility has shown marked antitumor efficacy against both murine tumors (CT26 and 3LL) and human xenogratfs (HCT116 and HCT15) in mice.
