Degradation and intracellular phosphorylation of showdomycin.

The anti-tumor agent showdomycin is degraded in the presence of 0.05 M NH4HCO3 (pH 8.0) to a compound which carries a negatively charged group. Together with previous data (Darnall et al., 1967) it is suggested that ammonia causes a basic hydrolysis of the maleimide moiety under formation of a maleic acid-like compound. During this modification the C-glycosidic bond is not split. Intracellularly, in mouse lymphoma cells (L5178y), showdomycin is phosphorylated to showdomycintriphosphate, via the mono- and diphosphate stage.[1]
