Description: ISA-2011B is a PIP5Kα (Phosphatidylinositol-4-phosphate 5-kinase-α) inhibitor. The overexpression of PIP5K1α is associated with poor prognosis in prostate cancer and correlates with an elevated level of the androgen receptor. ISA-2011B significantly inhibits growth of tumor cells in xenograft mice, which is mediated by targeting PIP5K1α-associated PI3K/AKT and the downstream survival, proliferation, and invasion pathways. PIP5K1α has high potential as a drug target, and compound ISA-2011B is interesting for further development of targeted cancer therapy.
