Background:

Cevipabulin fumarate (TTI-237 fumarate) is an oral, microtubule-active, antitumor compound and inhibits the binding of [3H] vinblastine to tubulin, with an IC50 of 18-40 nM for cytotoxicity in human tumor cell line[1][2]. IC50: 18-40 nM (microtubule in human tumor cells)[1].

Cevipabulin (0-50 nM, 72 hours) shows good activity (between 18 and 40 nM IC50 values) on cell lines from ovarian, breast, prostate, and cervical tumors[1].Flow cytometry experiments reveal that, Cevipabulin (TTI-237) at low concentrations (20-40 nM) produces sub-G1 nuclei and, at concentrations above 50 nM, it causes a strong G2-M block[1]. Cell Cytotoxicity Assay[1] Cell Line: Human cancer cell lines (SK-OV-3, MDA-MB-435, MDA-MB-468, LnCaP, and Hela cells).

Cevipabulin (TTI-2370)( 5, 10, 15, and 20 mg/kg, every 4 days for 4 cycles, in mice) is active by i.v. and p.o. administration against human tumor xenografts, showing dose-dependent effects, with good antitumor activity at 20 and 15 mg/kg[1]. Animal Model: Athymic nu/nu female mice implanted s.c. in the flank with 1×107 LoVo human colon adenocarcinoma cells[1].
