new methodology for the synthesis of fluorinated and non‐fluorinated 1H‐pyrazolo[3,4‐b]pyridin‐3‐ones was developed. The reactions proceed by cyclization of electron‐rich 3‐amino‐1H‐pyrazol‐5(4H)‐ones with 1,3‐diketones and the products were obtained in good to excellent yields and with excellent regioselectivity. The products, which can be regarded as deazapurine analogues, were tested for the alkaline
为氟化和非氟化的1的合成的新方法ħ -吡唑并[3,4- b ]吡啶-3-酮被开发。反应是通过将富含电子的3-氨基-1 H-吡唑-5(4 H)-1与1,3-二酮环化而进行的,所获得的产物具有良好的产率和极好的区域选择性。该产品可被视为脱氮嘌呤类似物,已测试了碱性磷酸酶(h- TNAP和h- IAP)和核苷酸焦磷酸酶/磷酸二酯酶(h- NPP1和h‐NPP3)抑制曲线。大多数衍生物对组织非特异性和肠道碱性磷酸酶和核苷酸焦磷酸酶(NPP1和NPP3)酶表现出选择性和有效的抑制作用。通过分子对接分析研究了最有效抑制剂的可能结合方式。
