title: Synthesis and antifungal activities of alanine-exchanged analogs of pradimicin A.
abstract: A series of pradimicin analogs were designed and synthesized to investigate the effect of the amino acid side chain on the antifungal activity. The alanine-exchanged analogs (3a approximately 3q) were synthesized from 4'-N-Cbz-pradimic acid by coupling with appropriate amino acids or their equivalents followed by deblocking. All the D-alpha-amino acid derivatives except D-proline analog, 3k retained the antifungal activity.
