What is Discovery of novel PARP/PI3K dual inhibitors with high efficiency against BRCA-proficient triple negative breast cancer about?
Co-targeting PARP and PI3K by PARP/PI3K dual inhibitors has been recognized as a promising chemotherapeutic strategy for the treatment of triple negative breast cancer (TNBC) in our previous work. To further explore novel and more potent PARP/PI3K dual inhibitors, a series of compounds were designed, synthesized and evaluated for their pharmacological properties, resulting in the candidate compound 12, a potent and highly selective PARP/PI3K dual inhibitor. Compared to Olaparib, compound 12 exhibits a superior antiproliferative profile against BRCA-proficient MDA-MB-468 cells. In MDA-MB-468 cell-derived xenograft model, compound 12 displayed excellent antitumor efficacy at a dose of 50 mg/kg, which is considerably more efficacious than the single administration of Olaparib or BKM120. Furthermore, compound 12 displayed good metabolic stability and high safety. Taken together, these results suggest that compound 12 as a novel PARP/PI3K dual inhibitor is worthy for further study.
