• Palladium‐Catalyzed Reductive Carbonylation of (Hetero) Aryl Halides and Triflates Using Cobalt Carbonyl as CO Source

  A generalized protocol for the reductive carbonylation of (hetero) aryl halides and triflates under CO gas‐free conditions using Pd/Co2(CO)8 and triethylsilane has been developed. The mild reaction conditions, enhanced safety, and wide substrate scope highlight its importance in routine organic synthesis.

  chemotype that yields noncompetitive, slow-binding inhibitors of LiTryR. Several compounds bearing (poly)aromatic substituents dramatically improve the ability to disrupt LiTryR dimerization relative to reference imidazoles. Molecular modeling studies identified an almost unexplored hydrophobic region at the interfacial domain as the putative binding site for these compounds. A subsequent structure-based

  通过破坏其同二聚体界面来抑制婴儿利什曼原虫锥硫酮二硫化物还原酶（Li TryR）已被证明是寻找新型抗利什曼原虫药物的替代且尚未开发的策略。概念证明首先是通过肽和肽模拟物获得的。基于之前报道的含有咪唑-苯基-噻唑支架的二聚化干扰剂，我们现在报道了一种新的基于 1,2,3-三唑的化学型，该化学型产生非竞争性、缓慢结合的Li TryR 抑制剂。相对于参考咪唑，几种带有（多）芳香族取代基的化合物显着提高了破坏Li TryR 二聚化的能力。分子建模研究确定了界面域中几乎未被探索的疏水区域作为这些化合物的假定结合位点。随后基于结构的设计产生了一种对称的三唑类似物，它表现出比Li TryR 更有效的抑制活性，并增强了杀利什曼病的活性。值得注意的是，其中几种新型含三唑化合物能够杀死细胞培养物中的细胞外和细胞内寄生虫。
