of four different trifluoromethylated metallocenetriazoles and their biological evaluation (M = Fe and Ru). The cytotoxicity of all compounds was evaluated using MCF-7, HT-29, PT-45 and GM5657 cells and IC50 values as low as 33 μM were found. It was shown that the metallocene moiety is crucial for the cytotoxic effect. The electrochemical behavior of triazoles 3–6 was investigated by cyclic voltammetry
我们报告了四种不同三氟甲基化茂金属三唑的简便合成及其生物学评价(M = Fe 和 Ru)。使用 MCF-7、HT-29、PT-45 和 GM5657 细胞评估了所有化合物的细胞毒性,发现 IC50 值低至 33 μM。结果表明,茂金属部分对细胞毒性作用至关重要。通过循环伏安法研究了三唑 3-6 的电化学行为。这些电化学测量表明,所有三唑都比二茂铁更不容易氧化。此外,通过 RP-HPLC 测定的 Log P 表明氟化衍生物的亲脂性增加,Log P 值高达 3.8。此外,通过将三唑 7 与氨基酸 L-亮氨酸偶联可以实现成功的生物偶联。

into a variety of molecules, there remain significant challenges regarding the enantioselective synthesis of SCF3-containing compounds. Here, an asymmetric trifluoromethylthiolation that proceeds through the enantioselective [2,3]-sigmatropicrearrangement of a sulfonium ylide generated from a metal carbene and sulfide (Doyle–Kirmse reaction) has been developed using chiral Rh(II) and Cu(I) catalysts
