Platinum-acridine conjugates were prepared from [PtCl2(ethane-1,2-diamine)] and the novel acridinylthioureas MeHNC(S)NMeAcr (6) and MeHNC(S)NMe(CH2CH2)NHAcr (15) by replacing one chloro leaving group in the cisplatin analogue with thiourea sulfur. In HL-60 leukemia cells, IC(50) values for 7 (Pt-tethered 6) and 16 (Pt-tethered 15) were 75 and 0.13 microM, respectively. In the ovarian cell lines 2008 and C13, 16 was active at micromolar concentrations and showed only partial cross-resistance with clinical cisplatin. Possible structure-activity relationships are discussed.
通过用硫脲硫取代顺铂类似物中的一个氯离去基团,由[PtCl2(乙二胺)]与新型吖啶基硫脲MeHNC(S)NMeAcr (6)和MeHNC(S)NMe(CH2CH2)NHAcr (15)制备了铂-吖啶共轭物。在HL-60白血病细胞中,7(铂连接的6)和16(铂连接的15)的IC(50)值分别为75和0.13 microM。在卵巢细胞系2008和C13中,16在微摩尔浓度下具有活性,并且与临床顺铂仅表现出部分交叉耐药性。讨论了可能的构效关系。
