一般描述
A cell-permeable cyclohexenecarboxylate that disrupts TLR4 interaction with adaptor molecules TIRAP and TRAM by selectively binding to TLR4, but not TLR1-3 or TLR5-10, via TLR4 intracellular Cys747 residue. Shown to effectively inhibit TLR4-mediated signaling events, including LPS-induced NO and inflammatory cytokines production in murine RAW264.7 macrophages (IC50 = 1.8, 1.3, and 1.9 nM, respectively, against NO, IL-6, and TNF-α production), TLR4/TIRAP-dependent NF-κB activity as well as TLR4/TIRAP- and TLR4/TRAM-dependent ISRE activity (IC50<300 nM) in HEK293-hTLR4/MD2-CD14 transfected with either TIRAP or TRAM. When administered at an i.v. dose of 3 mg/kg, TAK-242 is reported to completely prevent LPS- (7 mg/kg, i.p.) induced death in mice in vivo. Complete elimination of septic shock-induced death can be extended to live E. coli-infected mice when co-administered with ceftazidime (3 mg/kg TAK-242 and 20 mg/kg ceftazidime, i.v.).
