APH02174
Based on 1 Customer Validation
APH02174 is an orally effective and selective IRAK4 PROTAC degrader with a DC50 of 4.01 nM in THP-1 cells. APH02174 inhibits LPS (HY-D1056)-induced IL-6 release by degrading IRAK4 and blocking TLR/IL-1R downstream signaling. APH02174 exhibits favorable anti-inflammatory activity in both Imiquimod (HY-B0180)-induced psoriasis-like skin inflammation and collagen-induced arthritis models. APH02174 is useful for research on inflammatory diseases such as psoriasis and rheumatoid arthritis.
(Pink: IRAK4 ligand (HY-174470); Blue: Cereblon ligand (HY-45512); Black: linker).
