Phosphoinositide 3-kinase (PI3K) beta signaling is required to sustain cancer cell growth in which the tumor suppressor phosphatase and tensin homolog (PTEN) has been deactivated. This manuscript describes the discovery, optimization, and in vivo evaluation of a novel series of PI3Kbeta/delta inhibitors in which PI3Kbeta potency was built in a PI3Kdelta-selective template. This work led to the discovery of a highly selective PI3Kbeta/delta inhibitor displaying excellent pharmacokinetic profile and efficacy in a human PTEN-deficient LNCaP prostate carcinoma xenograft tumor model. In the experiment, the researchers used many compounds, for example, 2-Amino-4,6-dichloropyrimidine-5-carbonitrile (cas: 1277179-33-5Synthetic Route of C5H2Cl2N4).
2-Amino-4,6-dichloropyrimidine-5-carbonitrile (cas: 1277179-33-5) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion.Synthetic Route of C5H2Cl2N4
