fourth titanocene 3d was elucidated through a DFT calculation. All four titanocenes had their cytotoxicity investigated through preliminary in vitro testing on the LLC-PK (pig kidney epithelial) cell line in order to determine their IC50 values. Titanocenes 3a–d were found to have IC50 values of 97, 159, 88 and 253 μM, respectively. All four titanocene derivatives show significant cytotoxicity improvement
从6(2-甲氧基苯基)富烯(1a),6(3-甲氧基苯基)富烯(1b),6(3,4-二甲氧基苯基)富烯(1c)和6(3,4,5-三甲氧基苯基)富烯的反应中(1d)用LiBEt 3 H合成了锂化的环戊二烯中间体2a - d。然后将这些中间体用TiCl 4过渡金属化为钛,得到苄基取代的二茂钛双-[[(2-甲氧基-苄基)环戊二烯基]二氯化钛(IV)(3a),双-[[3-甲氧基-苄基)环戊二烯基]钛( IV)二氯化物(3b),双-[(3,4-二甲氧基-苄基)环戊二烯基]二氯化钛(IV)(3c)和双-[((3,4,5-三甲氧基-苄基)环戊二烯基]二氯化钛(IV)(3d)。通过单晶X射线衍射表征了三个钛金属3a - c,而通过DFT计算阐明了第四钛金属3d的结构。通过对LLC-PK(猪肾上皮)细胞系进行初步体外测试,对所有四种钛烷进行了细胞毒性研究,以确定它们的IC 50值。钛茂3a - d被发现具有IC
