TJ-M2010-5 is a MyD88 inhibitor that binds to the TIR domain of MyD88 to interfere with its homodimerization, and the TLR/MyD88 signal pathway[1][2]. TJ-M2010-5 can be used for the research of myocardial ischemia/reperfusion injury (MIRI)[2].

TJ-M2010-5 (40 µM) inhibits MyD88 homodimerization in transfected HEK293 cells in a concentration-dependent manner and suppresses MyD88 signaling in LPS (100 ng/mL)-responsive RAW 264.7 cells in vitro[1].TJ-M2010-5 (5-30 μM) prevents B cell proliferation and induces B cells apoptosis after stimulation with R848 (500 ng/mL)[3].

TJ-M2010-5 treatment statistically significantly reduces AOM/DSS-induced colitis and completely prevented CAC development with less related body mass loss, results in 0% mortality of treated mice, decreases cell proliferation, and increased apoptosis in colon tissue in a 10-week CAC mouse model[1].TJ-M2010-5 statistically significantly decreases TNF-α, IL-6, G-CSF, MIP-1β, IL-11, IL-17A, IL-22, and IL-23 serum concentrations in mice at both two and seven weeks postinduction, as well as TGF-β1 serum levels at seven weeks postinduction[1].
