RESUMO
Improved fermentation and isolation procedures for antitumor antimetabolites U-42,126 and U-43,795 increased drug yields 30-fold. The sensitivity limit of a newly developed assay is 0.03 μg of U-42,126 and 2.0 μg of U-43,795 per ml. The in vitro antimicrobial effect of both drugs was antagonized by histidine.
