Description

General description

A cell-permeable quinolinyl-benzothiazolamine compound that is reported to act as a RIP3-selective kinase inhibitor with >1,000-fold selectivity over a vast majority of more than 300 other kinases, including RIP1. RIP1 inhibitor Nec-1 (30 µM; Cat. Nos. 480065 & 505224 ) and genetic knockdown can be employed in conjunction with GSK′872 (3 µM) in delineating RIP1- vs. RIP3-dependency in Toll-like receptors- (TLRs) mediated necrosis and TNFR1-initiated necroptosis in the presence or absence of caspase inhibitor Z-VAD-FMK (25 µM; Cat. Nos. 627609 & 627610 ). While RIP3 and its downstream substrate MLKL are shown to mediate TLR3-initiated necrosis in the presence of Z-VAD-FMK in murine macrophage (BMDM & J774), fibroblast (3T3-SA & MEF), and endothelial (SVEC4-10) cultures, only in BMDM & J774 macrophage cultures is RIP1 involvement also seen in TLR3-mediated necrosis.
