building blocks (key components in clickchemistry). We report herein a highly robust and efficient strategy for high-throughput synthesis of a 325-member azide library. The method is highlighted by its simplicity and product purity. The utility of the library is demonstrated with the subsequent “click” synthesis of the corresponding bidentate inhibitors against PTP1B.

HPPH. Furthermore, specific functional contribution of the carboxylic acid side group at position 172 and the chiral methyl group at 3(1′) to the overall activity of the chimeric compounds was assessed. Among the conjugates investigated, the PS 10 was identified as the most effective candidate for achieving tumor cell-specific accumulation and yielding improved long-term tumor control.
Propargyl functionalized diazenes 1 were prepared by two different approaches and were examined as alkyne click components in copper-catalyzed azide–alkyne cycloadditions (CuAAC) with 2-(azidomethyl)pyridine 5a and four α-azido-ω-aminoalkanes C2–C5 (5b–e). Whereas the reactions with azidoalkylamines 5b–e reached completion with copper(II) sulfate without the need of reducing agent typically in no more

triazole hybrids were designed and synthesized by employing copper-catalyzed azide-alkyne cycloaddition (CuAAC). All the synthesized hybrids were characterized by their spectral data (1H NMR, 13C NMR, IR, and HRMS). The synthesized compounds were evaluated for their anticancer activity against five selected cancer cell lines including lung (A549), prostate (DU-145), cervical (Hela), breast (MCF-7),
通过使用铜催化的叠氮化物-炔烃环加成反应(CuAAC)设计并合成了一系列基于甲萘醌的新型三唑杂化物。所有合成的杂种均通过其光谱数据(1 H NMR,13 C NMR,IR和HRMS)进行表征。使用MTT评估了合成的化合物对五种选定的癌细胞系的抗癌活性,这些癌细胞系包括肺癌(A549),前列腺癌(DU-145),宫颈癌(Hela),乳腺癌(MCF-7)和小鼠黑素瘤(B-16)分析。筛选结果表明,大多数合成的化合物显示出显着的抗癌活性。在测试的化合物中,三唑5和6对所有细胞系均显示出有效的活性。特别是化合物6对MCF-7细胞系显示出比标准他莫昔芬和母体甲萘醌更高的效力。流式细胞仪分析表明,化合物6在G0 / G1期停滞了细胞周期,并诱导了凋亡细胞的死亡,这通过Hoechst染色,线粒体膜电位(ΔΨm)的测定和Annexin-V-FITC分析得到了进一步证实。因此,化合物6可以被认为是作为有效的抗癌治疗剂而进一步开发的先导分子。
