ABSTRACT:
The sea hare Dolabella auricularia has yielded many structurally distinct ptides which possess antineoplastic activity. Presently the compound denominated "dolastatin 10" represents the most important of such peptides because of its demonstrated potential as an anticancer drug.
The present invention relates to the systematic creation of seven unique pentapeptides by selectively coupling a tripeptide-trifluoroacetate salt with a preselected dipeptide trifluoroacetate salt which provide active molecules capable of emulating the measured therapeutic effect of dolastatin 10.
