LM9
LM9 is a potent, orally active MyD88 inhibitor. LM9 blocks TLR4/MyD88 binding, MyD88 homodimer formation, and TLR4/MyD88/NF-κB signaling pathway activation. LM9 prevents atherosclerosis by regulating inflammatory responses and oxidative stress in macrophages. LM9 efficiently mitigates inflammatory responses and fibrosis in obesity-induced cardiomyopathy. LM9 can be used for fibrosis and atherosclerosis research.

LM9 (5-10 μM; 1 h pretreat) attenuates Palmitic Acid (PA) (HY-N0830)-induced inflammation in mouse peritoneal macrophages by reducing proinflammatory cytokine production and ICAM-1 expression[1].
LM9 (5-10 μM; 1 h pretreat) suppresses PA-induced inflammation and NF-κB signaling activation in H9C2 cells[1].
LM9 (5-10 μM) inhibits PA-induced TLR4/MyD88 binding and MyD88 homodimer formation in HEK293T cells[1].
LM9 (5-10 μM; 1 h pretreat) alleviates PA-induced lipid accumulation and fibrosis in H9C2 cells, decreasing collagen 1/4 and TGF-β expression[1].
LM9 (24 h) does not affect the viability of mouse primary peritoneal macrophages up to 20 μM[2].
LM9 (10-20 μM; 1 h pretreat) reduces inflammatory responses in mouse primary peritoneal macrophages and RAW264.7 cells exposed to ox-LDL (HY-NP013) by suppressing TLR4-MyD88 complex formation, NF-κB activation, and MAPK phosphorylation[2].
LM9 (10-20 μM; 1 h pretreat) suppresses ox-LDL uptake and foam cell formation in mouse primary peritoneal macrophages, which is associated with reduced CD36 expression[2].
LM9 (10-20 μM; 1 h pretreat) reduces ox-LDL-induced ROS production in mouse primary peritoneal macrophages, and this effect is mediated by MyD88 inhibition[2].
