Hypothemycin exhibits antifungal and cytotoxic activity against some tumor cell lines partly attributed to inhibition of Ras-inducible genes. Hypothemycin facilitates the ubiquitinylation process of cyclin D1. Hypothemycin has been identified as a potent and selective inhibitor of threonine/tyrosine-specific kinase, MEK, and other protein kinases that contain a conserved cysteine residue in the ATP-binding site in in vitro studies.
