potential energy distribution (PED). Stability of complex (2) in DMSO solution was investigated by FT-IR (ATR) spectroscopy. The in vitro antiproliferative activity of cis-[PtCl2(3Br4Cl7AIH)2], cis-[PtCl2(3Cl7AIH)2] and cis-[PtCl2(3Br7AIH)2] was evaluated on selected human cancer cell lines and towards normal mouse fibroblast cell line (BALB/3T3). All complexes are more toxic than cisplatin against Es-2 (ovarian
摘要八种含7-氮杂吲哚(L = 7AIH)及其卤代衍生物的通式为顺式[PtCl2(L)2]的铂(II)配合物:L = 3-氯-7-氮杂吲哚(3Cl7AIH);3-溴-7-氮杂吲哚(3Br7AIH);4-氯-7-氮杂吲哚(4Cl7AIH);4-溴-7-氮杂吲哚(4Br7AIH);5-溴-7-氮杂吲哚(5Br7AIH); 制备了3-溴-4-氯-7-氮杂吲哚(3Br4Cl7AIH)和5-溴-3-氯-7-氮杂吲哚(5Br3Cl7AIH)。首次报道了两种复合物,顺式[PtCl2(3Br4Cl7AIH)2](2)和顺式[PtCl2(4Br7AIH)2]·DMF。后一种化合物的晶体结构已通过X射线衍射分析确定(空间群P43,a = 14.775(2),c = 41.640(8)A,V = 9090(3)A3,Z = 16)。对于所有这些复合物,通过实验振动(红外光谱和拉曼光谱)结合DFT计算,证实了固态
