Structure modification of the beta-alanine region (fragment C) of the potent antimitotic agent cryptophycin was investigated. This includes: (1) introduction of substituents at the previously unsubstituted C7 position of the macrolide ring and (:2) replacement of the (2R)-3-amino-2-methyl-propanoic acid (beta-alanine) with various (1)-amino acids to give the corresponding 15-membered unnatural cryptophycin analogs.
