Antineoplastic agents. 590. X-ray crystal structure of dolastatin 16 and syntheses of the dolamethylleuine and dolaphenvaline units
Three advances necessary to bring dolastatin 16 (1) into full-scale preclinical development as an anticancer drug have been accomplished. The X-ray crystal structure of dolastatin 16 has been solved, which allowed stereoselective syntheses of its two new
