Preparation and optimization of new 4-(morpholin-4-yl)-(6-oxo-1,6-dihydropyrimidin-2-yl)amide derivatives as PI3K[beta] inhibitors

From a HTS campaign, a new series of pyrimidone anilides exemplified by compound 1 has been identified with good inhibitory activity for the PI3K[beta] isoform. The structure of compound 1 in PI3K[gamma] was solved revealing a binding mode in agreement with the SAR observed on PI3K[beta]. These comp...

description From a HTS campaign, a new series of pyrimidone anilides exemplified by compound 1 has been identified with good inhibitory activity for the PI3K[beta] isoform. The structure of compound 1 in PI3K[gamma] was solved revealing a binding mode in agreement with the SAR observed on PI3K[beta]. These compounds displayed inhibition in the nanomolar range in the biochemical assay and were also potent p-Akt inhibitors in a PTEN-deficient PC3 prostate cancer cell line. Optimization of in vitro pharmocokinetic properties led to compound 25 exhibiting 52% bioavailability in mice and target engagement in an acute PK/PD study.
