  苯甲腈与甲氧基嘧啶和嘧啶酮的反应

  摘要：

  甲氧基嘧啶优先添加到氧化苯甲腈上，从而在其 C=N 双键上形成环加合物。然而，这些失去苄腈，得到相应的嘧啶酮。它们的 C=C 双键的环加成作用非常低，产物通常会经历开环过程，从而提供相应的肟。嘧啶酮优先为其氮原子提供加成产物，并且仅在 4-嘧啶酮的情况下，其 C=C 双键的环加合物才被分离出来。

  were studied as potential falcipain inhibitors and therefore potential antiparasitic lead compounds, with the 5-substituted-2-cyanopyrimidine chemical class emerging as the most potent and promising lead series. Through a sequential lead optimization process considering the different positions present in the initial scaffold, nanomolar and subnanomolar inhibitors at falcipains 2 and 3 were identified

  Falcipain-2和falcipain-3是疟原虫恶性疟原虫的木瓜蛋白酶家族半胱氨酸蛋白酶负责宿主血红蛋白水解以提供用于寄生虫蛋白质合成的氨基酸。研究了不同的杂芳基腈衍生物作为潜在的falcipain抑制剂，因此潜在的抗寄生虫铅化合物，其中5-取代的2-氰基嘧啶化学类别成为最有效和有前途的铅系列。考虑到初始支架中存在的不同位置，通过顺序的前导优化过程，鉴定出了在恶性激素2和3处的纳摩尔和亚纳摩尔抑制剂，并具有在微摩尔范围内对抗培养的寄生虫的活性。在铅分子中引入质子化胺后，对培养的寄生虫的活性显着提高了1000倍，而其他SAR趋势没有明显改变。
