  设计和合成非肽Ras CAAX模拟物作为有效的法呢基转移酶抑制剂。

  摘要：

  ras癌基因产物Ras的半胱氨酸法呢基化对于其转化活性是必需的，并且被法呢基转移酶（FTase）催化。Ras羧基末端四肽CAAX（C是半胱氨酸，A是任何脂肪族氨基酸，X是蛋氨酸或丝氨酸）是FTase识别的最小序列。我们在这里报告Ras CAAX非肽模拟物的设计，合成和生物学特性，其中半胱氨酸通过还原的伪肽键与4-氨基-3'-羧基联苯相连。这些非肽模拟物是FTase的有效抑制剂（IC50 = 40 nM，是最有效的抑制剂），对FTase的选择性高于GGTase I（香叶基香叶基转移酶I）。它们不是法呢基化的底物，没有肽特征，也没有可水解键。结构活性研究揭示了芳基环上羧酸位置以及半胱氨酸酰胺键还原的重要性。在4-氨基-3'-羧基联苯的2-位取代可提高抑制能力，而羧酸的去除则会导致抑制活性降低10倍。

  摘要：

  首次报道了钯催化芳基卤化物、Stille 交叉偶联和一锅两步 stannylation/Stille 交叉偶联 (SSC) 的无溶剂协议。带有受体、供体以及空间要求的取代基的（杂）芳基卤化物以高产率被甲锡烷基化和/或偶联。该反应在空气中由常规的乙酸钯 (II)/PCy3 (Pd(OAc)2/PCy3) 催化，使用可用的碱 CsF，并且不使用高纯度试剂。开发的合成程序用途广泛、稳健且易于扩展。没有溶剂，并消除了芳基锡烷的分离程序，使 SSC 协议简单、步骤经济且高效，用于通过一锅两步程序合成联芳。

  Pd(II)-sulfosalan complex as a water-soluble catalyst, we have developed an efficient synthesis of biaryls via Suzuki–Miyaura cross-coupling in water under aerobic conditions. The water-insoluble target molecules were isolated by simple filtration in analytical purity after washing with 0.01 M aqueous HCl (20 examples). In most cases, palladium contamination was below 5 ppm considered acceptable for active pharmaceutical
