Clickchemistry focuses on the development of highly selective reactions using simple precursors for the exquisite synthesis of molecules. Undisputedly, the CuI -catalyzed azide-alkynecycloaddition (CuAAC) is one of the most valuable examples of clickchemistry, but it suffers from some limitations as it requires additional reducing agents and ligands as well as cytotoxic copper. Here, we demonstrate
indexes [SI; calculated relative to the human dermal fibroblast (HDF) cell line], even higher than that of the reference compound cytarabine. Results of molecular docking studies of this type of macrolideantibiotics at the ribosomal tunnel, together with experimentally determined lipophilicity and aqueous solubility values, as well as biological assay data revealed the importance of the introduced functional

together with experimentally determined lipophilicity (clogP) and solubility show the importance of the chemical nature of the newly introduced triazole C(5) arm in the presence of attractive antibacterial and anticancer potency. The most cytotoxic active triazole conjugates having a hydrophobic and bulky C(5) arm showed higher selectivity toward cancer cell lines (HeLa, KB, MCF-7, Hep-G2, and U87) relative
Huisgen环允许的新的三唑桥接抗生素(获得6 - 16)与重构的C(5)螺旋霉素臂的。1 H– 1 H NOESY偶联表明溶液中新型衍生物的结构,并表明与螺旋霉素相比,重建的C(5)臂相对于糖苷配基部分的取向稍有不同(1)。生物学数据与实验确定的亲脂性(clogP)和溶解度的结合分析表明,在有吸引力的抗菌和抗癌药的存在下,新引入的三唑C(5)臂化学性质的重要性。相对于HDF正常细胞,具有疏水性和体积大的C(5)臂的最具细胞毒性的活性三唑共轭物对癌细胞系(HeLa,KB,MCF-7,Hep-G2和U87)的选择性要比亲螺旋霉素高。我们的研究表明,对于基于螺旋霉素的16元内酯大环内酯类药物,有趣的抗菌[MIC (肺炎链球菌(S. pneumoniae)〜1.2μM]和抗癌药[IC 50(HepG2)〜6μM]性质的存在,醛基并不是至关重要的。糖苷配基。
