| Bioactivity | IRAK4-IN-22 (compound 18) is an orally active, potent and selective IRAK4 inhibitor with IC50 values of 3 and 17 nM for IRAK4 and TAK1, respectively. IRAK4-IN-21 effectively inhibits IL-23 production (IC50=0.10 µM) and can be used in studies of autoimmune diseases such as plaque psoriasis and psoriatic arthritis[1]. |
| Invitro | IRAK4-IN-21 (a 4-fold serial dilution from 10 µM; 1 h) decreases the levels of IL-23 (in THP-1 and DC cells), IL-6 (in HUVEC cells) and MIP-1β (in human whole blood)[1]. Cell Viability Assay[1] Cell Line: |
| In Vivo | IRAK4-IN-21 (75 mg/kg; p.o.; single) shows moderate efficacy in acute animal model studies for the inhibition of IL-6 production[1]. Animal Model: |
