  Pharmacomodulation on Gold-NHC complexes for anticancer applications – is lipophilicity the key point?

  摘要：

  A series of four new mononuclear cationic gold(I) complexes containing nitrogen functionalized N-heterocyclic carbenes (NHCs) was synthesized and fully characterized by spectroscopic methods. The X-ray structures of three complexes are presented. These lipophilic gold(I) complexes originate from a pharmacomodulation of previously described gold(I)-NHC complexes, by replacing an aliphatic spacer with an aromatic one. The Log P values of the resulting complexes increased by 0.7-1.5, depending on the substituents in comparison to the aliphatic-linker systems. The new series of complexes has been investigated in vitro for their anti -cancer activities in PC-3 (prostate cancer) and T24 (bladder cancer) cell lines and in the non-cancerous MC3T3 (osteoblast) cell line. All tested complexes show high activities against the cancer cell lines with GI(50) values lower than 500 nM. One complex (11) has been selected for further investigations. It has been tested in vitro in six cancer cell lines from different origins (prostate, bladder, lung, bone, liver and breast) and two non-cancerous cell lines (osteoblasts, fibroblasts). Moreover, cellular uptake measurements were indicative of a good bioavailability. By various biochemical assays, this complex was found to effectively inhibit the thioredoxin reductase (TrxR) and its cytotoxicity towards prostate PC-3, bladder 124 and liver HepG2 cells was found to be ROS-dependent.

  and molecules containing two or more nitrogen-containing heterocycle were successfully obtained in good to excellent yield. The use of an appropriate acid catalyst with suitable acidity enabled a protonation of basic nitrogen-containing heterocycle, thus can overcome significantly the interference from the basic substrate. Stronger or weaker Brønsted acids cannot match the specific requirements for protonating

  具有多个碱性位点的氮杂芳烃（Ar (N)NR）的酸催化合成经常遇到由碱性底物对酸性催化剂的毒害效应引起的固有问题。因此，迄今为止大多数报道的催化系统在 Ar(N)NR 的合成中效率较低。以p值范围为-3.0~1.0的布朗斯台德酸为催化剂，建立了通用且可靠的克劳森-卡斯反应方法，并成功获得了含有两个或多个含氮杂环的分子。良率至优良率。使用适当酸度的酸催化剂可以使碱性含氮杂环质子化，从而可以显着克服碱性底物的干扰。较强或较弱的布朗斯台德酸无法满足质子化碱性底物和活化亲电缩醛分子的具体要求，使得它们不适合这种特殊的合成反应。采用类似的方法，对于一些含有一个或多个碱性位点的底物，Paal-Knorr反应和多索茶碱的亲电烯丙基化反应也进行得很好。
