RS-61443: successful rescue therapy in refractory renal rejection.

Academic Article

Abstract

  • RS-61443, the morpholinoethyl ester of mycophenolic acid (mPA), is a potent, noncompetitive, reversible inhibitor of eucaryotic inosine monophosphate (IMP) dehydrogenases. Because of the importance of the guanosine and deoxyguanosine nucleotides in activating phosphoribosyl pyrophosphate (PRPP) synthesis and ribonucleotide reductase, respectively, it was postulated that depletion of GMP (and consequently GTP and GDP) would have antiproliferative effects on lymphocytes. Furthermore, since lymphocytes rely on de novo pruine synthesis whereas other cell types do not, antiproliferative effects produced in this way are more selective for lymphocytes than other cell types.
