Usage

Biological Activity

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

Dolastatins 24. Synthesis of (-)-dolastatin 10. X-Ray molecular structure of N,N-dimethylvalyl-valyl-dolaisoleuine tert-butyl ester

Total synthesis of the extraordinary antineoplastic constituent, dolastatin 10, from the Indian Ocean mollusc Dolabella auricularia has been summarized. The final synthetic step involved diethyl cyanophosphonate-mediated coupling of Dov-Val-Dil with Dap-Doe. Improved syntheses of these important precursors has led to a very practical synthesis of natural dolastatin 10. Important details of the HPLC and high-field (500 MHz) NMR characterization techniques employed to confirm the purity of dolastatin 10 have been recorded.

A practical approach to asymmetric synthesis of dolastatin 10

Dolastatin 10, an antineoplastic agent for cancer chemotherapy, is a linear peptide possessing N,N-dimethyl Val-OH, l-valine, (3R,4S,5S)-dolaisoleucine, (2R,3R,4S)-dolaproine and (S)-dolaphenine. Our efficient synthesis includes the following three key features: (1) SmI2-induced cross-coupling was employed to couple aldehyde 11 with (S)-N-tert-butanesulfinyl imine 12 to generate the required stereocenters of Dap (7); (2) asymmetric addition of chiral N-sulfinyl imine 10 provided a straightforward approach to the synthesis of the protected Doe ((S,S)-8); (3) a practical method to the key subunit Val-Dil (24a) has been established as an alternative synthetic route for the synthesis of this challenging chemical structure.

Synthesis and antitumor activity of novel dolastatin 10 analogs

Dolastatin 10 (1) is a potent antineoplastic pentapeptide. Novel dolastatin 10 analogs each modified at one of the constituent amino acid derivatives, were synthesized and their antitumor activity was evaluated against P388 leukemia in mice. The structural requirements for antitumor activity are discussed. Some of the analogs, 31c, 35c, 38b, and 50c showed excellent activity in vivo. Highly active 50c, which lacks the thiazole group of 1, was selected for further development as an antitumor agent.
