methods. In particular, we showed that, in the solid state, the pyridine and the triazole rings of 3b adopted an uncommon cis configuration which stems from intermolecular hydrogen bonds. Preliminary assays demonstrated a promising nanomolar inhibitory activity against carbonic anhydrase isoform IX for both ligands and complexes with a strong affinity Ki of 2.8 nM for ligand 3a. More interestingly, complex
抽象的 在这项工作中,通过经典的点击化学方法制备了两个含有4-取代的苯磺酰胺药效基团的二齿2-吡啶基-1,2,3-三唑配体(3a和3b),以及它们相应的rh配合物,一般为4a和4b。制备了[ReCl(CO)3(L)](L = 3a或3b)式,并通过光谱方法(IR,NMR,MS,UV-Vis),元素分析,X射线衍射和使用DFT和TD-DFT方法。尤其是,我们表明,在固态下,3b的吡啶和三唑环采用罕见的源于分子间氢键的顺式构型。初步测定表明,对碳酸酐酶同工型IX的配体和复合物都具有极好的纳摩尔抑制活性,对配体3a的亲和力K i为2.8 nM 。更有趣的是,复合物4b对脱靶的hCA I和hCA II表现出明显的针对hCA IX的选择性,这使该化合物成为有希望的潜在抗癌药物候选物。
