Herein, we communicate our recent medicinal chem. efforts which have culminated in a series of PI3Kδ/γ dual inhibitors structurally featuring a seven-membered spirocyclic spacer. Compound 26, the most potent one among them, exhibited superior PI3Kδ inhibitory activity (IC50 = 1.0 nM) to that of the approved PI3Kδ inhibitor Idelalisib. Besides, it exerted remarkable anti-proliferative efficacy against human malignant B-cell line SU-DHL-6 with GI50 value of 33 nM. The biochem. assay against the other three class I PI3K isoforms identified compound 26 as a potent PI3Kδ/γ dual inhibitor with considerable selectivity over PI3Kα and PI3Kβ. In SU-DHL-6 cells, a dramatic down-regulation of PI3K signaling was observed following compound 26-treatment at the concentration as low as 10 nM. Inspiringly, the pharmacokinetic (PK) study in Sprague-Dawley (SD) rats revealed it was orally available with a favorable bioavailability (F = 87.5%). Overall, compound 26, a promising PI3Kδ/γ dual inhibitor, has the potential to emerge as a clin. candidate for the treatment of leukocyte-mediated malignancies after extensive functional investigation. In the experiment, the researchers used many compounds, for example, 4-Amino-6-chloropyrimidine-5-carbonitrile (cas: 60025-09-4HPLC of Formula: 60025-09-4).
4-Amino-6-chloropyrimidine-5-carbonitrile (cas: 60025-09-4) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.HPLC of Formula: 60025-09-4
