  用于硫醇介导摄取的环状硫代磺酸盐：级联交换剂、转运蛋白、抑制剂

  摘要：

  硫醇介导的摄取正在成为一种强大的穿透细胞的方法。环状低硫属元素化物 (COC) 已被确定为能够实现和抑制硫醇介导的摄取的特殊支架，因为它们可以充当动态共价级联交换器，即每次交换都会产生一个新的共价连接交换器。在这项研究中，我们的重点是基本上未开发的具有较高氧化水平的 COC。潜在动态共价交换级联的定量表征表明，即使在低 pH 值下，环状硫代磺酸盐 (CTO) 的初始开环也会高速进行。释放的亚磺酸盐在非质子环境中与二硫化物交换，但在质子环境中则更少。因此引入疏水域以将 CTO 引导到疏水口袋中以增强其反应性。配备了这样的导演组，荧光标记的 CTO 比流行的芦笋酸更有效地进入活细胞的胞质溶胶。作为竞争性药物，CTO 可抑制各种 COC 转运蛋白和 SARS-CoV-2 慢病毒载体的摄取。使用不同转运蛋白发现的正交趋势支持多个细胞伙伴的存在，以解释硫醇介导的摄取的不同表达。二聚体的主要自我抑制和

  具有手性二硫醚配体的阳离子铱配合物：氢化条件下的合成、表征和反应性

  摘要：

  为了研究硫取代基和金属环尺寸对乙酰氨基丙烯酸酯加氢反应的影响，制备了一系列含有手性二硫醚配体的阳离子 IrI 配合物。在配合物 6、7 和 10 的情况下，由于硫转化过程，在溶液中观察到非对映异构体的混合物。相比之下，通过使用抑制配合物 8 和 9 中 S 反转的双环配体可以有效地控制这种流动行为。 配合物 10b 的固态结构仅显示一种非对映异构体，其中硫取代基处于相对反位和整体SCSSCSSSS 在配位的二硫醚配体上的构型。含有七元和六元金属环 (6b–d, 7b,c, 10a,b) 的铱配合物通过 S-配体取代与底物反应，而这种取代的速率与氟原子在芳环上的位置有关。相反，含有双金属环（8 和 9）的配合物不会被底物置换。根据相应二氢化物配合物（13和14）的高稳定性分析配合物8和9的催化氢化活性。在这两种情况下，四种可能的非对映二氢化物物质中只有两种在溶液中形成。(© Wiley-VCH
