Soblidotin is a derivative of dolastatin 10, which was isolated from the Indian Ocean sea hare, Dolabella auricularia, in 1987. Soblidotin inhibits tubulin polymerization, resulting in cell cycle arrest and induction of apoptosis. It has a broad spectrum of antitumor activity against various murine tumors – P388 leukemia, Colon26 and LLC carcinomas, B16 melanoma and M5076 sarcoma – as well as human tumor xenografts, MX-1, LX-1 and SBC-3 carcinomas. Soblidotin is currently undergoing clinical evaluation and, in phase II clinical trials for solid tumours.

Sample Use Guides

In Vivo Use Guide

The recommended dose for phase II studies of Soblidotin is 2.4 mg/m(2) given i.v. over 60 minutes, on days 1 and 8 every 21 days.

Route of Administration: Intravenous

In Vitro Use Guide

Treatment with 10(-7) g/mL Soblidotin rapidly disrupted the microtubule cytoskeleton in human umbilical vascular endothelial cells (HUVEC), and significantly enhanced vascular permeability in HUVEC monolayers.
