Neocarzilins A and B, Novel Polyenones from Streptomyces Carzinostaticus
摘要:
Novel chlorinated polyenones, neocarzilins A (1) and B (2) have been isolated from the mycelium of Streptomyces carzinostaticus var. F41 and their structures were determined on the basis of spectroscopic analysis. Neocarzilin A (1) showed potent antileukemic activity.
