ST 2825_product_DataBase

Bioactivity

ST 2825 is a specific MyD88 dimerization inhibitor. ST2825 interferes with recruitment of IRAK1 and IRAK4 by MyD88, causing inhibition of IL-1β-mediated activation of NF-κB transcriptional activity[1][2].

Target

MyD88

Invitro

ST2825 blocks IL-1R/TLR signaling by interfering with MyD88 homodimerization. ST2825 inhibits this interaction in a concentration-dependent manner with ~40% inhibition of dimerization at 5 μM ST2825 and 80% inhibition at 10 μM ST2825[1].

In Vivo

ST2825 dose-dependently inhibits IL-1β-induced production of IL-6 in treated mice after oral administration. The animals are administered orally with the appropriate vehicles or ST2825 at doses ranging from 50 to 200 mg/kg, 5 min prior to i.p. injection with 20 μg/kg IL-1β. ST2825 exertes a significant inhibition of IL-1β-stimulated production of IL-6 at 100 and 200 mg/kg[1].
