Description: | TH1020 is a potent and selective toll-like receptor 5 (TLR5)/flagellin complex antagonist with an IC50 of 0.85 μM. TH1020 inhbits flagellin-induced TLR5 signaling. TH1020 is inactive against TLR2, TLR3, TLR4, TLR7 and TLR8[1]. |
Target: | IC50: 0.85 μM (toll-like receptor 5 (TLR5)/flagellin complex)[1] |
In Vitro: | TH1020 inhibits the downstream signaling transduction mediated by the formation of the TLR5/Flagellin complex. TH1020 is suggested to compete with flagellin and disrupt its association with TLR5. TH1020 almost completely abolishes the TLR5-mediated TNF-α secretion at 0.37 μM[1]. The IL-17C secretion is almost completely abolished by TH1020 (0.5 μM) in bacterial strain C83901 infected IPEC-J2 cells[2]. Blocking TLR5 with TH1020 (0.5 μM) dramatically inhibits porcine beta-defensin (pBD)-2, claudin-1 and -2 mRNA expression in C83091 infected IPEC-J2 cells[2]. |
