[CpMo(CO)2(IMes)(CH3CN)][BF4] (6) have been synthesized and fully characterized. The stability of metal−NHC ligand bonds in these compounds under oxidative conditions has been investigated. The thermally stable Mo(VI) dioxo NHC complex [CpMoO2(IMes)][BF4] (9) has been isolated by the oxidation of the ionic complex 6 by TBHP (tert-butyl hydrogen peroxide). Complex 6 can be applied as a very active (TOFs up to 3400

Metal N‐heterocycliccarbene (NHC) complexes are a promising class of anti‐cancer agents displaying potent in vitro and in vivo activities. Taking a multi‐faceted approach employing two clickable photoaffinity probes, herein we report the identification of multiple molecular targets for anti‐cancer active pincer gold(III) NHC complexes. These complexes display potent and selectivecytotoxicity against
金属N杂环卡宾(NHC)络合物是一类有前途的抗癌药物,在体外和体内均表现出强大的活性。我们采用两个可点击的光亲和探针的多角度方法,在此我们报告了抗癌活性夹金(III)NHC复合物的多个分子靶标的鉴定。这些复合物在带有人类宫颈癌和肺癌异种移植物的小鼠中显示出对培养的癌细胞的有效和选择性的细胞毒性以及体内抗肿瘤活性。我们的实验揭示了金(III)配合物与多个细胞靶标(包括HSP60,波形蛋白,核磷蛋白和YB-1)的特异性结合,以及预期的下游作用机理。此外,Pt II和Pd II 类似物还可以结合金(III)络合物靶向的细胞蛋白,从而在设计具有多个分子靶标的抗癌金属药物时发现了独特的钳状环金属化金属-NHC支架。
