(1) and (S,S)-(+)-2,3-Bis(tert-butylmethylphosphino)quinoxalinedichlorogold(III) tetrachloroaurates(III) (2) were formed, respectively, in moderate yields. The structure of (S,S)-(+)-2,3-Bis(tert-butylmethylphosphino)quinoxalinedichlorogold(III) tetrachloroaurates(III) (2) was further confirmed by X-ray crystallography. The antiproliferative activities of the two compounds were evaluated in a panel of
本文报道了两种带有 (R,R)-(–)-2,3-双(叔丁基甲基膦基)喹喔啉 (R,R-QuinoxP*) 或 (S,S)-的 Au(III) 配合物的合成(+)-2,3-双(叔丁基甲基膦基)喹喔啉 (S,S-QuinoxP*) 配体。通过使两当量的 HAuCl4.3H2O 与一当量的相应 QuinoxP* 配体反应,(R,R)-(–)-2,3-双(叔丁基甲基膦基)喹喔啉二氯金(III)四氯金酸盐(III)(1)和(S,S)-(+)-2,3-双(叔丁基甲基膦基)喹喔啉二氯金(III)四氯金酸盐(III)(2)分别以中等产率形成。(S,S)-(+)-2,3-双(叔丁基甲基膦基)喹喔啉二氯金(III)四氯金酸盐(III)(2)的结构通过X射线晶体学进一步证实。在一组细胞系中评估了这两种化合物的抗增殖活性,并显示出与金诺芬和顺铂相当的有希望的结果,IC50 值介于 1.08 和 4.83 µM 之
