Oxasetin

Oximidine III is an anti-tumor antibiotic. Oximidine III can selectively inhibit the growth of 3Y1 in rat fibroblasts with degeneration of various tumor genes. Oximidine III inhibits v-H-ras-3Y1, v-src-3Y1 cells and the normal 3Y1 cells with IC50s (nM) of 14, 4.5 and 140, respectively. Oximidine III stops RAS-or SRC-denatured cells at G1 phase of the cell cycle and increases p21WAF1 expression[1].
