a peripheral imidazole group. The imidazole ring posed some problems in the click chemistry putatively due to Cu(II) coordination, but Boc protection of the imidazole and removal of oxygen from the reaction mixture provided effective strategies. Pharmacological studies revealed two monosubstituted imidazoles (6h,p) with <10 nM H4R affinities and >10-fold H4R/H3R selectivity. Both compounds possess
组胺H 3(H 3 R)和H 4(H 4 R)受体引起了药物化学界的极大兴趣。鉴于它们相对较高的同源性,但治疗前景却大相径庭,因此对两种受体的配体选择性至关重要。我们使用具有[1,2,3]三唑核心的配体询问H 4 R / H 3 R的选择性。Cu(I)辅助的“点击化学”被用来组装各种[1,2,3]三唑化合物(6a - w和7a - f),许多含有外围咪唑基团。咪唑环可能由于Cu(II)配位而在点击化学中造成了一些问题,但是咪唑的Boc保护和从反应混合物中除去氧气提供了有效的策略。药理研究表明,两种单取代的咪唑(6h,p)的亲和力<10 nM H 4 R和H 4 R / H 3 R选择性> 10倍。两种化合物均具有环烷基甲基,并且似乎靶向H 4中的亲脂性口袋R具有很高的空间精度。[1,2,3]三唑支架的使用进一步证明了以下概念,即间隔区长度或外围基团的简单改变可以逆转对H 3 R的选择性。提

[reaction: see text] Alkyl azides react with saturated ketones upon treatment with Lewisacids to afford ring-expansion products through the azido-Schmidt reaction, but this reaction does not proceed when alpha,beta-unsaturated ketones are used. In this study, alkyl azides were reacted with enones in the presence of Lewisacids to give enaminones (vinylogous amides), which formally involve a ring contraction

potent and selective sulfone hydroxamate inhibitors SC‐76276, SC‐78080 (SD‐2590), and SC‐77964, potent MMP inhibitors have been designed and synthesized to append a boron‐rich carborane cluster by employing click chemistry to target tumor cells that are known to upregulate gelatinases. Docking against MMP‐2 suggests binding involving the hydroxamate zinc‐binding group, key H‐bonds by the sulfone moiety
