  3. APH02174

APH02174 is a highly selective and orally active IRAK4 PROTAC degrader with the DC50 of 4.01 nM in THP-1 cells. APH02174 blocks inflammatory signals by inhibiting IL-6 release. APH02174 can be used for research on inflammatory conditions such as psoriasis vulgaris and rheumatoid arthritis.

IC50 & Target

IRAK4

4.01 nM (DC50)

In Vitro

APH02174 (0.24-1000 nM) can selectively degrade IRAK4 protein in various cells, including THP-1 (DC50 = 4.01 nM), hPBMCs (DC50 = 0.43 nM) and mouse PBMCs (DC50 = 3.57 nM) [1].
APH02174 (0.03-2000 nM; 24 h) significantly inhibits the Lipopolysaccharides (LPS) (HY-D1056) induced IL-6 release in the hPBMCs (IC50 = 16.43 nM) [1].

In Vivo

APH02174 (10-100 mg/kg; twice daily; for 7 days) reduces imiquimod-induced psoriasis-like skin inflammation significantly degrades the IRAK4 protein level in the spleen of the Imiquimod (IMQ) (HY-B0180) induced mice[1].
APH02174 (30 or 100 mg/kg; p.o.; once daily; for 14 days) significantly improves arthritis in the rheumatoid arthritis mice[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
