sparfosic acid 
A stable transition state analogue for an aspartate transcarbamylase- cartalyzed reaction with antineoplastic activity. Sparfosic acid is a stable transition analogue of the activated complex for the reaction catalyzed by aspartate transcarbamylase, the first step in the pyrimidine biosynthetic pathway. This agent inhibits de novo pyrimidine biosynthesis and increases the extent to which fluorouracil metabolites are incorporated into RNA. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
