一种多胺生物合成天然副产物，作为甲硫腺苷磷酸化酶（MTAP）的内源性底物。蛋白羧甲基转移酶的细胞渗透性，可逆性和ATP竞争性抑制剂，可诱导白血病U937细胞凋亡。还充当PC12细胞中NGF诱导的酪氨酸磷酸化的抑制剂，并阻断星形胶质细胞和胶质瘤细胞中的FGF-2受体酪氨酸激酶。 一种细胞可渗透、可逆和ATP竞争性的多胺生物合成天然副产物，作为甲硫腺苷磷酸化酶（MTAP）的内源性底物。在白血病U937细胞中有效抑制蛋白羧甲基转移酶并诱导凋亡。还抑制FGF-2受体酪氨酸激酶活性以及人星形胶质细胞和胶质瘤细胞的增殖。 A cell-permeable, reversible, and ATP-competitive naturally-occurring co-product of polyamine biosynthesis that acts as an endogenous substrate of methylthioadenosine phosphorylase (MTAP). Potently inhibits the protein carboxymethyltransferase and induces apoptosis in leukemia U937 cells. Also inhibits FGF-2 receptor tyrosine kinase activity as well as the proliferation of human astrocytes and glioma cells. A naturally occurring co-product of polyamine biosynthesis that acts as an endogenous substrate of methylthioadenosine phosphorylase (MTAP). A cell-permeable, reversible, and ATP-competitive inhibitor of protein carboxymethyltransferase and induces apoptosis in leukemia U937 cells. Also acts as an inhibitor of NGF-induced tyrosine phosphorylation in PC12 cells and blocks FGF-2 receptor tyrosine kinase in astrocytes and glioma cells.
