[GRAPHICS]
Structure-activity relationships of the west amino acid modified analogues
of rhodopeptins, novel antifungal tetrapeptide isolated from Rhodococcus sp
ecies Mer-N1033, have been investigated, Among the analogues synthesized, 2
,2-difluoro and 2-hydroxy derivatives retained the antifungal activity with
better physical properties, i.e., solubility or acute toxicity.
