As part of our investigation into the pyrazolo[1,5-a]pyridines as novel PI3K inhibitors, we report a range of analogues where the central linker portion of the molecule was varied while retaining the pyrazolo[1,5-a]pyridine and arylsulfonyl or arylcarbonyl groups. Isostere generating software BROOD was used to assist with producing ideas. The isoform selectivity of the compounds varied from pan-PI3K for compound 41 to p110α-selective for compound 58 or p110δ-selective for compound 57. The latter two compounds varied only in their sulphur oxidation state.
作为我们对吡唑并[1,5-a]吡啶作为新型PI3K抑制剂的研究的一部分,我们报告了一系列类似物,其中分子的中央连接部分进行了变化,同时保留了吡唑并[1,5-a]吡啶和芳基磺酰或芳基羰基基团。我们使用了异构体生成软件BROOD来帮助生成创意。这些化合物的同种型选择性从化合物41的全PI3K到化合物58的p110α选择性,或者化合物57的p110δ选择性。这两个后者化合物仅在其硫氧化态上有所不同。
