PI3K-IN-6 (compound 20a) is an oral active and highly selective phosphoinositide 3-kinase (PI3K) β/δ inhibitor, with IC50 values of 7.8 nM/5.3 nM for PI3K β/δ, respectively. PI3K-IN-6 (compound 20a) has potential top treat phosphatase and tensin homolog (PTEN) feficient tumors[1]. PI3Kβ|7.8 nM (IC50)|PI3Kδ|5.3 nM (IC50)|PI3Kα|850 nM (IC50)
