Mycophenolate mofetil may be the 2-morpholinoethyl ester of MPA. MPA is a potent, selective, reversible and uncompetitive inhibitor of in sine monophosphate dehydrogenises, and for that reason inhibits the de novo pathway of guanosine nucleotide synthesis without incorporation into DNA. Because T – and B-lymphocytes are acutely dependent for their proliferation on de novo synthesis of p urines whereas additional cell types can make use of salvage pathways, MPA has more potent cytostatic results on lymphocytes than on other cells.
