Myriocin
Based on 12 publication(s) in Google Scholar
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.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.29 mg/mL (0.72 mM); Clear solution
This protocol yields a clear solution of ≥ 0.29 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (2.9 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
