Abstract
The design, synthesis and in vitro activities of novel alpha-bromoacryloyl pyrazole, imidazole and benzoheterocyclic derivatives of distamycin A, in which the amidino moiety has been replaced by moieties of different physico-chemical features are described, and the structure-activity relationships are discussed. In spite of the relevance of these modifications on the distamycin frame, these derivatives showed significant growth inhibitory activity against mouse leukemia L1210 cells. Therefore, the presence of the amidino moiety, and in general of a basic moiety, is not an absolute requirement for biological activity of alpha-bromoacrylic derivatives of distamycin.File | Dimensione | Formato | |
