  Structure Overhaul Affords a Potent Purine PI3Kδ Inhibitor with Improved Tolerability

  摘要：

  PI3K delta catalytic activity is required for immune cell activation, and has been implicated in inflammatory diseases as well as hematological malignancies in which the AKT pathway is overactive. A purine PI3K delta inhibitor bearing a benzimidazolonepiperidine motif was found to be poorly tolerated in dog, which was attributed to diffuse vascular injury. Several strategies were implemented to mitigate this finding, including reconstruction of the benzimidazolonepiperidine selectivity motif. Structure-based design led to the identification of O- and N-linked heterocycloalkyls, with pyrrolidines being particularly ligand efficient and kinome selective, and having an improved safety pharmacology profile. A representative was advanced into a dog tolerability study where it was found to be well tolerated, with no histopathological evidence of vascular injury.
