Ly93 is a selective and orally active sphingomyelin synthase 2 (SMS2) inhibitor, with an IC50 of 91 nM[1].

In Vivo

Ly93 (100 mg/kg, i.g. once daily for 7 days) significantly decreases the plasma SM levels of C57BL/6J mice[1].
Ly93 dose-dependently attenuates the atherosclerotic lesions in the root and the entire aorta as well as macrophage content in lesions, in apolipoprotein E gene knockout mice[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6J mice[1].
Dosage: 100 mg/kg.
Administration: I.G. (gavage) once daily for 7 days.
Result: Significantly decreased the plasma SM levels compared with vehicle group.
Animal Model: ApoE KO mice (eight-week-old)[1].
Dosage: 12.5 or 40 mg/kg.
Administration: I.G. (gavage) once daily.
Result: The levels of ALT and AST in the plasma of apoE KO mice did not show statistic changes when compared with the control group.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
