  Discovery of pyrazolo[1,5-a]pyridines as p110α-selective PI3 kinase inhibitors

  摘要：

  We have made a novel series of pyrazolo[1,5-a]pyridines as PI3 kinase inhibitors, and demonstrated their selectivity for the p110 alpha isoform over the other Class Ia PI3 kinases. We investigated the SAR around the pyrazolo[1,5-a] pyridine ring system, and found compound 5x to be a particularly potent example (p110 alpha IC50 0.9 nM). This compound inhibits cell proliferation and phosphorylation of Akt/PKB, a downstream marker of PI3 kinase activity, and showed in vivo activity in an HCT-116 human xenograft model.

  We have developed a novel ring-opening difluorination process for pyrazoloazines. Utilizing 2.5 equivalents of Selectfluor®, this method enables electrophilic difluorination and subsequent ring-opening of pyrazoloazines, yielding the corresponding difluoroalkylated azines. Additionally, our protocol extends to the decarbonylative difluorination of pyrazoloazines when starting with a formyl group at

  我们开发了一种新型的吡唑并嗪开环二氟化工艺。该方法利用 2.5 当量的 Selectflu®，实现亲电二氟化和随后吡唑并嗪的开环，产生相应的二氟烷基化吖嗪。此外，我们的方案还扩展到以 C3 位甲酰基为起始的吡唑并嗪的脱羰二氟化，证明了该方法的多功能性和广泛适用性。二氟化化学的这一进步为二氟化化合物的合成提供了一条新途径，可能丰富药物化学和材料科学从业者的工具包。
