    Product Description

    Alobresib is an inhibitor of bromodomain and extra-terminal domain (BET) proteins.1,2 It inhibits proliferation of MEC-1 chronic lymphocytic leukemia cells (CLL; IC50 = 46.4 nM).1 Alobresib (400 nM) decreases the levels of Blk and Myc and increases the levels of IκBα in patient-derived CLL cells co-cultured with nurse-like cells (NLC). It inhibits proliferation of USPC-ARK-1 and USPC-ARK-2 uterine serous carcinoma (USC) cells with IC50 values of 31 and 27 nM, respectively.2 Alobresib (10 and 20 mg/kg, p.o.) reduces tumor growth in a USPC-ARK-2 USC mouse xenograft model.

    WARNING This product is not for human or veterinary use.
