Myriocin (Thermozymocidin) 是一种可以从Myriococcum albomyces,Isaria sinclairi和Mycelia sterilia中分离的真菌代谢产物,是一种有效的丝氨酸-棕榈酰转移酶 (SPT) 抑制剂,是鞘脂从头合成的关键。Myriocin 抑制亚基因组 HCV-1b 复制子和基因型 2a 感染性 HCV 的 JFH-1 株的复制,抑制 HCV 感染的IC50为 3.5 μg/mL。
生物活性 | Myriocin (Thermozymocidin), afungalmetabolite could be isolated fromMyriococcum albomyces,Isaria sinclairiandMycelia sterilia, is a potent inhibitor ofserine-palmitoyl-transferase (SPT)and a key enzyme in de novo synthesis of sphingolipids. Myriocin suppresses replication of both the subgenomic HCV-1b replicon and the JFH-1 strain of genotype 2a infectiousHCV, with anIC50of 3.5 μg/mL for inhibiting HCVinfection[1][2][3]. |
IC50& Target | Serine-palmitoyl-transferase (SPT)[1] |
体外研究 (In Vitro) | Myriocin (Thermozymocidin; 0-10000 nM; 96 h; Huh7/Rep-Feo cells) inhibits the replication of a subgenomic hepatitis C virus (HCV) genotype 1b replicon[2]. Myriocin (100 nM; 72 h) decreases in the sphingomyelin content of Huh7 cells[2].
Western Blot Analysis[2] Cell Line: | Huh7/Rep-Feo cells | Concentration: | 0, 300, and 1000 nM | Incubation Time: | 96 hours | Result: | Decreased the levels of HCV NS5A in a concentration-dependent manner. |
|
体内研究 (In Vivo) | Myriocin (Thermozymocidin; 0-1 mg/kg; i.p.; daily, for 5 d; male Balb/c mice) blocks de novo synthesis of sphingolipids in vivo by SPT inhibition and induced c-myc expression in liver[1].
Animal Model: | Male Balb/c mice (22 g, 7-8 weeks old)[1] | Dosage: | 0, 0.1, 0.3, and 1.0 mg/kg | Administration: | Intraperitoneal injection; daily, for 5 days | Result: | Altered not significantly the levels of plasma alanine aminotransferase and aspartate aminotransferase. Decreased free sphinganine in a dose-dependent manner in both the liver and kidney. Decreased in the activity of liver SPT with a correlation coefficient of -0.76. Increased the expression of liver c-myc in a dose-dependent manner.
