wish to report a green synthesis of new pharmaceutically active peptide triazoles as potent factor Xa inhibitors, an important drug target associated with the treatment of diverse cardiovascular diseases. The new inhibitors were synthesized in three steps, featuring cycloaddition reactions (high atom economy), microwave-assisted organic synthesis (energy efficiency), and copper nanoparticle catalysis
绿色化学的实施在制药行业减少废物方面取得了可喜的成果。然而,药物活性化合物和成分的早期可持续开发仍然是一个相当大的挑战。在此,我们希望报道一种新型药物活性肽三唑的绿色合成方法,作为有效的 Xa 因子抑制剂,这是与治疗多种心血管疾病相关的重要药物靶点。新型抑制剂通过三步合成,具有环加成反应(高原子经济性)、微波辅助有机合成(能源效率)和铜纳米粒子催化,从而具有地球丰富的金属特征。获得的分子显示出FXa抑制作用,IC 50值低至17.2 μM,并且在HEK293和HeLa细胞中没有相关的细胞毒性。这些结果展示了开发具有药理学潜力的新分子所应用的方法的环境潜力和化学意义。

strategy, which combines alkyne-azide cycloaddition between p-hydroxyphenacyl azide and alkyne derivatives to form a 1,2,3-triazole adduct and subsequent photochemical release of the triazole moiety via a photo-Favorskii rearrangement, is introduced. The first step can also involve photorelease of a strained alkyne and its Cu-free click reaction with azide.
[NH4]2[MS4CunXn] (M = W, Mo; X = Br, I; n = 2, 4, 6) as novel copper(I) catalysts for Huisgen 1,3-dipolar cycloadditions. The experiments indicate that the thiometallic ligands can stabilize copper(I) ions and improve their solubility. Interestingly, these cluster compounds have very different catalytic performances in copper(I)-catalyzed azide–alkyne cycloadditions (CuAACs), which may correlate to their
我们研究了杂硫金属W(Mo)/ S / Cu团簇[NH 4 ] 2 [MS 4 Cu n X n ](M = W,Mo; X = Br,I; n = 2,4,6)作为新型铜( I)Huisgen 1,3-偶极环加成的催化剂。实验表明,硫金属配体可以稳定铜离子并提高其溶解度。有趣的是,这些簇化合物在铜(I)催化的叠氮化物-炔烃环加成(CuAAC)中具有非常不同的催化性能,这可能与其不同的氧化还原电位有关。簇[NH 4 ] 2 [MS 4 Cu 4 I 4业已发现]是一种非常坚固有效的CuAAC催化剂,并在室温下在极性溶剂或无溶剂条件下以优异的产率用于合成多种1,4-二取代的1,2,3-三唑。
Synthesis and preliminary anticancer evaluation of new triazole bisphosphonate-based isoprenoid biosynthesis inhibitors
The synthesis of a new set of triazole bisphosphonates 8a-d and 9a-d presenting an alkyl or phenyl substituent at the C-4 or C-5 position of the triazole ring is described. These compounds have been evaluated for their antiproliferative activity against MIA PaCa-2 (pancreas), MDA-MB-231 (breast) and A549 (lung) human tumor cell lines. 4-hexyl- and 4-octyltriazole bisphosphonates 8b-c both displayed
