    Product Description

    CU-32 is an inhibitor of cyclic GMP-AMP (cGAMP) synthase (cGAS; IC50 = 0.45 µM).1 It reduces DNA-, but not Sendai virus-, induced dimerization of IFN regulatory factor 3 (IRF3; Item No. 22811) in THP-1 cells, indicating selectivity for the cGAS DNA sensing pathway over the RIG-I-MAVS RNA sensing pathway. It is also selective for cGAS (Item No. 22810) over toll-like receptors (TLRs) at 50 µM. CU-32 decreases IFN-stimulatory DNA-induced production of IFN-β in THP-1 cells when used at concentrations of 10, 30, and 100 µM.

    WARNING This product is not for human or veterinary use.
