Myriocin is an amino fatty acid antibiotic derived from certain thermophylic fungi, in this case Mycelia sterilia. It is a potent immunosuppressant having 10- to 100-fold more activity than cyclosporin A.[1] Myriocin is a potent inhibitor of serine palmitoyltransferase (Ki = 0.28 nM), the enzyme that catalyzes the first step of sphingolipid biosynthesis. [2] It disrupts substratum adhesion of melanoma cells.[3] It also suppresses cell proliferation in the murine cytotoxic T cell line CTLL-2 (IC50 = 15 nM) via apoptosis.[2],[4] Myriocin suppresses replication of the hepatitis C virus in a murine model.[5]
Myriocin是从某些热耐受真菌中提取的氨基脂肪酸类抗生素,具有10-至100倍于环孢霉素A的免疫抑制作用[1]。Myriocin是丝氨酰基转移酶(Ki = 0.28 nM)的强效抑制剂,该酶催化鞘磷脂生物合成的第一步[2]。它可以破坏黑色素瘤细胞的底物附着[3]。Myriocin还通过凋亡途径抑制小鼠细胞毒性T细胞系CTLL-2的增殖(IC50 = 15 nM)[2],并抑制乙型肝炎病毒在小鼠模型中的复制[5]。
