Dolastatin 10 is an unusual peptide of marine origin which binds to tubulin, inhibits microtubule assembly, resulting in the formation of tubulin aggregates and inhibition of mitosis. Dolastatin 10 has been used in trials phase II studying the treatment of Sarcoma, Leukemia, Lymphoma, Liver Cancer, among others. In case of hormone-refractory prostate cancer, it lacks significant clinical activity as a single agent and also dolastatin-10 is inactive against hepatobiliary and pancreatic carcinomas.

Sample Use Guides

In Vivo Use Guide

advanced pancreaticobiliary cancers: dolastatin-10 400 microg/m(2) was administered intravenously by bolus every 21 days. Restaging CT scans were obtained every 2 cycles metastatic prostate adenocarcinoma: dolastatin-10 was administered at a dose of 400 microg/m2 i.v. every 3 weeks. Dose escalation to 450 microg/m2 was permitted.

Route of Administration: Intravenous

In Vitro Use Guide

Dolastatin 10 had growth inhibitory activity against four small-cell lung cancer (SCLC) cell lines (NCI-H69, -H82, -H446, -H510) with IC50 values ranging from 0.032 to 0.184 nM. All four cell lines exhibited evidence of apoptosis after 48 h of exposure to 1.3 nM dolastatin 10. Immunoblot analysis revealed that 1.3 nM dolastatin 10 altered the electrophoretic mobility of bcl-2 in NCI-H69 and -H510 cells within 16 h of treatment. Incubation of protein extract from dolastatin 10-treated NCI-H69 and -H510 cells with calcineurin resulted in the disappearance of the altered mobility species, suggesting dolastatin 10-induced bcl-2 phosphorylation.
