Biological Activity for TAK 242

TAK 242 is a toll-like receptor 4 (TLR4) signaling inhibitor. Binds to intracellular domain of TLR4. Inhibits LPS-induced cytokine production in vitro (IC₅₀ values are 1.3, 1.3 and 3.2 nM for IL-6, TNFα and NO production). Reduces lesion volume in a mouse model of cerebral cavernous malformations (CCMs). Also attenuates increased cytokine levels in a mouse sepsis model, when given in combination with ceftazidime. Cell permeable.
