(S)-GSK-F1 (Compound 28) is an inhibitor for type III phosphatidylinositol 4-kinase α (PI4KIIIα). (S)-GSK-F1 inhibits PI4Kα, PI4Kβ, PI4Kγ, PI3Kα, PI3Kβ and PI3Kδ with pIC50 of 8.3, 6.0, 5.6, 5.6, 5.1 and 5.6, respectively. (S)-GSK-F1 exhibits anti-hepatitis C virus (HCV) activity through inhibition of HCV replication. (S)-GSK-F1 exhibits moderate pharmacokinetic characters in rat model[1].

PI4KIIIα: 8.3 (pIC₅₀); PI4KIIIβ: 6.0 (pIC₅₀); PI3Kα: 5.6 (pIC₅₀); PI3Kδ: 5.6 (pIC₅₀); PI3Kβ: 5.1 (pIC₅₀)
