  have highest potency with alkyl substitution at both C-6 and C-7. The most potent compounds were 7c and 7e which produced a 50% inhibition in the rat PCA test at doses of about 10 micrometerM/kg following subcutaneous administration and showed activity after oral administration. Related 4-hydroxy-3-nitro-2(1H)-naphthalenones had no effect on rat PCA in doses up to 500 micrometerM/kg.

  Herein, we present m-C–H olefination on derivatives of phenylacetic acids by tethering with a simple nitrile-based template through palladium catalysis. Notably, the versatility of the method is evaluated with a wide range of phenylacetic acid derivatives for obtaining the meta-olefination products in fair to excellent yields with outstanding selectivities under mild conditions. Significantly, the

  在此，我们通过钯催化与简单的腈基模板连接，在苯乙酸衍生物上进行m -C-H 烯化。值得注意的是，该方法的多功能性是用范围广泛的苯乙酸衍生物来评估的，以便在温和的条件下以中等至极好的收率和出色的选择性获得间烯烃化产物。重要的是，本策略成功地用于合成药物/天然产物类似物（萘普生、布洛芬、扑热息痛和胆固醇）。

  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。
