Mizoribine 生物活性

描述 Mizoribine (Bredinin, MZB) is an immunosuppressive drug used in renal transplantation, IgA nephropathy, lupus erythematosus and childhood nephrotic syndrome[1]. After entering into cells, Mizoribine can firstly be phosphorylated to become its active form, Mizoribine 5’-monophosphate (MZ-5-P) by adenosine kinase. Then, MZ-5-P, the active form of Mizoribine, can selectively inhibit inosine monophosphate (IMP) dehydrogenase (ki = 10 nM) and guanosine monophosphate (GMP) synthetase (ki = 10 μM) [1], which are required for synthesis of GMP from IMP in de novo way. The immunosuppressive effect of Mizoribine on T cells may due to specific perturbation of guanine nucleotide, the second messengers in T cell activation, caused by Mizoribine. Meanwhile, Mizoribine can also prevent cells from exiting G1 phase and entering S phase by blocking T cell proliferation via a guanine nucleotide-dependent mechanism, which further contributes to its effect on immunosuppression[2].
作用机制 Mizoribine can inhibit T cell activation both through perturbation of guanine nucleotide and anti-proliferation[2].
