Description
AZD-8186 is a potent and selective inhibitor of PI3Kβ and PI3Kδ. It shows efficacy against PTEN-null tumors, which become dependent on the PI3Kβ isoform. The loss of the PTEN protein results in upregulation of the PI3K/AKT pathway, making small molecules that target PI3Kβ viable in cancers like PTEN-deficient breast and prostate tumors.
