Abstract

Our screening for antitumor antibiotics against transformed cells resulted in the isolation of a new active metabolite, oximidine III, from Pseudomonas sp. QN05727. This substance selectively inhibited the growth of rat 3Y1 fibroblasts transformed with various oncogenes. In ras- or src-transformed cells, oximidine III arrested the cell cycle at G1 phase and increased the expression of p21WAF1.
