SRX3207 is an orally active and first-in-class dual Syk/PI3K inhibitor, with IC50 values of 10.7 nM and 861 nM for Syk and PI3Kα, respectively. SRX3207 relieves tumor immunosuppression[1][2].

SRX3207 is an orally active and first-in-class dual Syk/PI3K inhibitor, with IC50 values of 10.7 nM and 861 nM for Syk and PI3Kα, respectively. SRX3207 relieves tumor immunosuppression[1][2]. SRX3207 (10 μmol/L) is able to block p-AKT at concentration[1].SRX3207 has sufficient solubility in water (43 μmol/L)[1]. SRX3207 (10 mg/kg, orally) increases antitumor immune response[1].

Syk: 10.7 nM (IC₅₀); PI3Kα: 861 nM (IC₅₀); PI3Kδ: 1280 nM (IC₅₀); PI3Kγ: 11100 nM (IC₅₀); Zap70: 1300 nM (IC₅₀)
