L6H21 binds to MD-2 (myeloid differentiation protein-2, Kd=33.3 µM) and blocks its interaction with TLR4 (toll-like receptor 4) in LPS-stimulated cells, inhibiting TNFα and IL-6 production.1 Attenuates disease progression in a high-fat diet (HFD) induced NASH mouse model.2 Inhibits obesity-induced cardiomyopathy and fibrosis.3 Reduces ethanol plus LPS-induced liver injury via inhibition of NLRP3 inflammasome activation.4 Provides cardioprotective effects5 and protects against cognitive impairment and brain pathologies in HFD prediabetic rats6. Cell permeable. Active in vivo.
