= Me, OMe, Cl; R2 = Me, OMe, F, Cl; R3 = Me, Et; not all combinations) are synthesised in two steps from simple phenols in 36–53 % overall yield. The highly crystalline (4 X‐ray structures) complexes are active against MCF‐7 (breast) and HCT‐116 (colon) cancer cell lines showing widely varying GI50 values in the range 1–100 µM depending on R1–R3. Highest activities are realised when R1 = OMe and R2
八面体钛(IV)配合物的反式,聚体-钛[Ti R 3 N(CH 2 C ^ 6 ħ 2 -2-O-4-R 2 -6-R 1)2 } 2 ](R 1 = Me中,OME ,Cl; R 2 = Me,OMe,F,Cl; R 3 = Me,Et;并非所有组合)是由简单的酚分两步合成的,总收率为36-53%。高度结晶的(4个X射线结构)复合物对MCF-7(乳腺癌)和HCT-116(结肠)癌细胞系具有活性,根据R 1 –R 3的不同,其GI 50值在1–100 µM范围内变化很大。当R 1 = OMe和R 2,R 3 = Me时,可实现最高的活性(对于MCF-7,GI 50约为1 µM,对于HCT-116为2-3 µM)。在相同的细胞系中,它们分别比顺铂的活性大8倍和3倍。这些钛配合物对癌细胞系表现出一定的选择性。与非癌症(MRC-5)成纤维细胞相比,MCF-7的最高高7倍。还指出了细胞活性模式指
