nitrogen atoms. The synthesized guanidines and their complexes were initially screened for their anti-microbial activities, and Brine Shrimps Lethality assay. The complexes were also screened for in vitro cytotoxicity activity in human cell lines carcinomas A498, EVSAT, H226, IGROV, M19, MCF-7 and WIDR. The results show a moderate level of cytotoxicity against these seven human cancer cell lines as compared
一系列均配型铜(II)配合物(的1A-8A)与N,N',N“三取代胍,[铜(II)PhCONHC(NHR)NPH} 2 ](其中R =苯基(1A),Ñ丁基(图2a),仲-丁基(图3a),环己基(图4a),1-萘基(图5a),2,4-二氯苯基(图6a),3,4- -二氯(7A),和3,5-二氯苯基(8a))已合成并通过元素分析,FT-IR,UV可见,1 H和13表征1 H NMR光谱和单晶X射线衍射分析。X射线晶体结构表明,配合物2a和4a在固态是单核的,并且铜原子周围的几何形状几乎是正方形平面。在两种情况下,N,N',N''-三取代的胍配体均通过氧和氮原子与Cu(II)配位。首先对合成的胍及其复合物的抗微生物活性进行筛选,并进行盐卤虾致死率测定。还对复合物进行了体外筛选在人细胞株A498,EVSAT,H226,IGROV,M19,MCF-7和WIDR中的细胞毒性活性。结果表明,与标准化疗
