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