摘要: PI3K, AKT, and mTOR are key kinases from PI3K signaling pathway being extensively pursued to treat a variety of cancers in oncology. To search for structurally differentiated back-up candidate PF-04691502, which is currently phase I/II clinical trials treating solid tumors, lead optimization effort was carried out with tricyclic imidazo[1,5]naphthyridine series. Integration structure-based drug design physical properties-based yielded potent selective PI3K/mTOR dual kinase inhibitor PF-04979064. This manuscript discusses the series, both improved vitro potency addressed number ADMET issues including high metabolic clearance mediated by P450 aldehyde oxidase (AO), poor permeability, solubility. An empirical scaling tool developed predict human liver S9 assay data derivatives that were AO substrates.
