Dolastatin 10
Dolastatin 10 is an antitumor agent [1].
Dolastatin 10 is a potent antimitotic polypeptide isolated from a marine animal and is developed as a potential antitumor agent. Dolastatin 10 is found to have activity to inhibit tubulin polymerization with IC50 value of 1.2μM. Besides that, it potently inhibits vincristine binding to tubulin with a Ki value of 1.4μM in a noncompetitive manner. Dolastatin 10 also shows moderate effect on enhancing the binding of colchicines to tubulin. In addition, Dolastatin 10 has the inhibitory activity in tubulin-dependent GTP binding [1].
In the cellular assay, Dolastatin 10 shows activity against some human leukaemia, lymphoma and solid tumour cell lines (such as OVCAR-3 and NSCLC) with IC50 values ranging from 0.1nM to 10nM. It is currently tested in the clinical trials [2].
