SMU127 is an agonist of the toll-like receptor 1/2 (TLR1/2) heterodimer.1 It induces NF-κB signaling in cells expressing human TLR2 (EC50 = 0.55 µM) but not cells expressing human TLR3, -4, -5, -7, or -8 when used at concentrations ranging from 0.1 to 100 µM. SMU127 induces the production of TNF-α in isolated human peripheral blood mononuclear cells (PBMCs) when used at concentrations ranging from 0.01 to 1 µM. In vivo, SMU127 (0.1 mg/animal) reduces tumor volume in a 4T1 murine mammary carcinoma model.
