Reduction of trans-fatty acids from food [1]

摘要

Six novel urea triazene prodrugs have been synthesized to apply in antibody-directed enzyme prodrug therapy (ADEPT). The chemical and plasmatic stability of l-glutamate triazene prodrugs were evaluated and the chemical reactivity was mainly attributed to an intramolecular catalysis promoted by the neighbouring carboxylate group of the glutamic moiety. These prodrugs showed an elevated binding to plasma proteins. The l-glutamate triazenes were evaluated as prodrugs of the alkylating agent's monomethyltriazenes, by activation of the bacterial enzyme carboxypeptidase G2 (CPG2). The synthesized prodrugs have been shown to be good substrates for CPG2, and therefore new candidates for ADEPT strategy.
