Web15 ott 1990 · In addition, a tripeptide containing dolavaline, valine and dolaisoleuine with all asymmetric carbons identical conflgurationally to those in dolastatin 10 was found to be about 30% as effective as dolastatin 10 in inhibiting tubulin polymerization. Cytotoxic effects were much more sensitive to alterations in the dolastatin 10 structure. WebA complicated but extremely important scheme of synthesis has been developed for synthesizing, dolaisoleuine, dolaproine, dolaphenine and dolavaline from readily available starting materials such as Z-(S,S)isoleucine, S-phenylalaline, S-phenylalaninol, S-prolinol, S-mandelate, and S-valine. The requisite amino acids have been combined using several …
