Thailanstatin A(Cat No.:I037191) is a natural product isolated from a marine-derived Streptomyces sp. that exhibits potent antiproliferative activity against a variety of cancer cell lines. It acts as a potent inhibitor of the proteasome-associated deubiquitinase USP9X, which is involved in regulating the degradation of several important cellular proteins. Thailanstatin A has been shown to induce apoptosis and inhibit tumor growth in vivo and may have potential as a therapeutic agent for the treatment of cancer.
