Rationally Designed Inhibitors of Inosine Monophosphate Dehydrogenase
摘要:
Functionalized 2-alkyl derivatives of inosinic acid have been synthesized to serve as reversible as well as irreversible inhibitors of the human type II enzyme inosine monophosphate dehydrogenase. These compounds were designed to react with Cys-331 of the enzyme to form covalent bonds so as to interfere with the normal enzyme mechanism which involves attack of Cys-331 at C-2 of the substrate. Mass spectrometric analysis of the reaction products after enzymatic degradation confirmed the appropriateness of the inhibitor design.

A series of 2-substituted inosine monophosphate (IMP) and inosine derivatives were synthesized and tested for inhibitory activity against IMP dehydrogenase from Escherichia coli. All of the IMP analogues that possessed electron-withdrawing substituents on the phenyl ring of a benzylthio group placed at the 2-position of IMP showed strong inhibition, which was competitive with IMP. No evidence of hydrophobic interactions of the 2-substituent with the enzyme was observed.
