引起非洲昏睡病的布鲁氏锥虫寄生虫的半胱氨酸蛋白酶罗氏蛋白酶已成为开发新候选药物的目标。基于三嗪腈部分作为亲电头基,使用基于结构的设计对酶的S1,S2和S3口袋的取代基进行了优化研究,得到了抑制剂,其抑制常数在个位数纳摩尔范围内。全面的结构-活性关系阐明了活性位点各个口袋的结合偏好。S1口袋可容忍各种取代基,其中优先选择挠性和碱性侧链。S2取代基的变化导致抑制亲和力低至2 n M的高亲和力配体用于带有环己基取代基的化合物。对S3口袋的系统研究表明,它有可能通过芳香族载体实现高活性,这些芳香族载体与形成口袋的一部分的平面肽骨架进行堆叠相互作用。用结构相关酶人组织蛋白酶L的X射线晶体结构分析证实了分子建模所提出的三嗪配体系列的结合模式。通过优化周期确定的最佳取代基修饰的配体可实现亚微摩尔对培养寄生虫增殖的抑制。在基于细胞的测定中,在抑制剂上引入基本侧链导致抗锥虫活性提高了35倍。最后,为了减少三

Ammoniomethyl trifluoroborates are very powerful reagents that can be used to access biologically relevant aryl‐ and heteroaryl‐methylamine motifs via Suzuki–Miyaura cross‐couplings. Until now, this method was limited to the production of tertiary and primary amines. The synthesis of a large array of secondary ammoniomethyltrifluoroborates has been achieved through a one step nucleophilic substitution

A chemoselective intramolecular Buchner reaction employing iodoniumylides as safe carbene precursors has been developed. Iodoniumylides are generated in situ from N-benzyl-2-cyanoacetamides and PhI(OAc)2 in the presence of base and undergo intramolecular Buchner reaction under catalysis from Cu(OAc)2·H2O, affording fused cyclohepta-1,3,5-triene derivatives in up to 85% yield. The N,N-dibenzyl-2-cyanoacetamides
