General description

A potent immunosuppressant. Displays 10- to 100-fold more potent immunosuppressant activity than cyclosporin A. Potently inhibits serine palmitoyltransferase (SPT; Ki = 280 pM) thereby blocking the synthesis of ceramide. Disrupts substratum adhesion of melanoma cells. Inhibits cell proliferation and induces apoptosis in IL-2 dependent murine cytotoxic T lymphocyte cell line CTLL-2.

Biochem/physiol Actions

Cell permeable: no
Primary Target
Serine palmitoyltransferase
Product does not compete with ATP.
Reversible: no
Target Ki: 280 pM against serine palmitoyltransferase

Warning

Toxicity: Harmful (C)

Reconstitution

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.

A potent immunosuppressive activity was found in the culture broth of the fungus Isaria sinclairii (ATCC 24400). The metabolite, ISP-I ((2S,3R,4R)-(E)-2-amino-3,4-dihydroxy-2- hydroxymethyl-14-oxoeicos-6-enoic acid, myriocin = thermozymocidin) suppressed the proliferation of lymphocytes in mouse allogeneic mixed lymphocyte reaction, but had no

Human health is seriously threatened by mycotoxin contamination, yet health risk assessments are typically based on just one mycotoxin, potentially excluding the additive or competitive interactions between co-occurring mycotoxins. In this investigation, we evaluated the individual or combined toxicological effects

In our previous study, the sphingosine-like immunosuppressant, ISP-1, was found to suppress the proliferation of an interleukin-2-dependent cytotoxic T cell line, CTLL-2, through the inhibition of serine palmitoyltransferase, which catalyzes the committed step of sphingolipid biosynthesis. Analysis of the effect

In the present study, we demonstrate a model cell system for evaluating the specificity of inhibitors of serine palmitoyltransferase (SPT), the enzyme that catalyzes the first step of sphingolipid biosynthesis. The LY-B strain is a Chinese hamster ovary (CHO) cell

ISP-1/myriocin is a new type of remarkably potent immunosuppressant, the structure of which is homologous to sphingosine. ISP-1/myriocin inhibited the proliferation of an IL-2-dependent mouse cytotoxic T cell line, CTLL-2, at nanomole concentrations. ISP-1/myriocin inhibits serine palmitoyltransferase activity at picomole
