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.

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
