series of novel pyrazolo[3,4-d]pyrimidin-4-one derivatives were synthesized and evaluated for their anti-phosphodiesterase-5 (PDE-5) activity. A total of 28 compounds, containing alkyl and aryl groups at the 1-N and 3-C positions on the pyrazole ring, and also bearing different alkyl substituents on the piperazine ring were synthesized. Four compounds (4d, 5d, 6d, and 5o) were found to have better
合成了一系列新型吡唑并[3,4- d ]嘧啶-4-酮衍生物,并评估了它们的抗磷酸二酯酶5 (PDE-5) 活性。共合成了 28 种化合物,它们在吡唑环的 1-N 和 3-C 位含有烷基和芳基,在哌嗪环上也带有不同的烷基取代基。发现四种化合物(4d、5d、6d和5o)对 PDE-5 具有更好的抑制活性(IC 50 < 10 nM)。所有四种最活跃的化合物都在 N1 位包含一个苯环。含有 3,5-二甲基哌嗪基的化合物比其他化合物表现出更好的活性。这些结果表明化合物5o可用作开发新的 PDE-5 抑制剂的先导结构。
