Two new platinum(II)-based complexes bearing a bone-targeting group were synthesized and characterized. They both have excellent affinity for hydroxyapatite (HA), which is abundant in human bone tissues. Their antitumor activities against five human cancer cell lines (U2OS, A549, HCT116, MDA-MB-231 and HepG2) were evaluated and compared with cisplatin (CDDP). Though the antitumor efficacies of new
合成并表征了两个带有骨靶向基团的新的基于铂(II)的复合物。它们都对人骨组织中丰富的羟基磷灰石(HA)具有极好的亲和力。评价了它们对五种人类癌细胞系(U2OS,A549,HCT116,MDA-MB-231和HepG2)的抗肿瘤活性,并与顺铂(CDDP)进行了比较。尽管新复合物的抗肿瘤作用低于CDDP,但与L02正常肝细胞相比,它们对HepG2肝癌细胞的选择性更高。形态学研究显示出细胞凋亡的典型特征,细胞周期分布分析表明,该复合物可通过诱导G2 / M期细胞周期停滞来抑制癌细胞,这与CDDP的作用机理类似。
