MMG-11 quarterhydrate is a potent and selective antagonist of human TLR2 which inhibits both TLR2/1 and TLR2/6 signaling with low cytotoxicity. The IC 50 s of MMG-11 quarterhydrate for Pam 3 CSK 4 -induced hTLR2/1 and for Pam 2 CSK 4 -induced hTLR2/6 responses is 1.7 μM and 5.7 μM, respectively[1].

MMG-11 neither shows cellular toxicity nor interference with signaling induced by other TLR agonists, IL-1β or TNF. MMG-11 (0.01-100 μM) shows no cytotoxic effects up to 100 μM in peripheral blood mononuclear cells (PBMCs) [1]. Cell Cytotoxicity Assay [1] Cell Line: PBMCs Concentration: 0.01, 1, 10, 100 μM Incubation Time: Result: Showed no cytotoxic effects up to 100 μM.
