A cell-permeable benzotropolone compound that competes against Pam3CSK4- for TLR1/TLR2 heterodimer binding (Ki = 410nM) and selectively antagonizes against Pam3CSK4-induced RAW264.7 cellular NO production (IC50 = 580nM) without apparent cytotoxicity (up to 100uM and 24h). Exhibits no antagonist activity toward TLR2/TLR6, TLR3, TLR4, TLR7 at 0.5uM and little inhibitory potency against a panel of 10 kinases at 5uM (by <11% inhibition).
