Abstract: Chemical optimization of pyrazolopyridine 1, focused on cellular potency, isoform selectivity and microsomal stability, led to the discovery of the potent, selective and orally available PI3Kδ inhibitor 5d. On the basis of its desirable potency, selectivity and pharmacokinetic profiles, 5d was tested in the trinitrophenylated aminoethylcarboxymethyl-Ficoll (TNP-Ficoll)-induced antibody production model, and showed higher antibody inhibition than a 4-fold oral dose of the starting compound 1. These excellent results suggest that 5d is a potential candidate for further studies in the treatment of autoimmune diseases and leukocyte malignancies.
