生物活性:
Myriocin (Thermozymocidin), a fungal metabolite could be isolated from Myriococcum albomyces, Isaria sinclairi and Mycelia sterilia, is a potent inhibitor of serine-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 infectious HCV, with an IC50 of 3.5 μg/mL for inhibiting HCV infection.

体内研究:
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.Animal Model:Male Balb/c mice (22 g, 7-8 weeks old)
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.

体外研究:
Myriocin (Thermozymocidin; 0-10000 nM; 96 h; Huh7/Rep-Feo cells) inhibits the replication of a subgenomic hepatitis C virus (HCV) genotype 1b replicon.Myriocin (100 nM; 72 h) decreases in the sphingomyelin content of Huh7 cells.
