  7-((4-Substituted)piperazin-1-yl) derivatives of ciprofloxacin: Synthesis and in vitro biological evaluation as potential antitumor agents

  摘要：

  Ciprofloxacin (CP), an antibiotic has been shown to have antiproliferative and apoptotic activities in several cancer cell lines. Moreover, several reports have highlighted the interest of increasing the lipophilicity to improve the antitumor efficacy. These studies have led us to synthesize new CP derivatives of various lipophilicities and to evaluate their activity in five human cancer cell lines. With an easy and cost-efficient procedure, 31 7-((4-substituted)piperazin-1-yl) derivatives of CP were prepared that displayed IC50 values ranging from mu M to mM concentrations and are non-toxic in vivo in healthy mice as shown by their maximal tolerated dose (MTD) indices >80 mg/kg. Several derivatives displayed higher in vitro antitumor activity than parent CP however this was not dependent on the lipophilicity of the substituent. Among all synthesized derivatives, the most potent were 2 and 6h whose IC50 values were <= 10 mu M in three (derivative 2) or four (derivative 6h) cancer cell lines. (C) 2009 Elsevier Ltd.

  cell line was the most sensitive to the presence of the obtained conjugates. The value of IC50 for oleic acid conjugate (4) was 7.7 μM, and it was 12 times lower than for CP alone (101.4 μM). The studied derivatives induced late apoptosis in all cancer cell lines, but not in normal cells. The most potent apoptosis inducer was conjugate 4, that resulted in the highest percentage of PC3 cells in late

  环丙沙星（CP）对某些癌细胞具有确定的细胞毒性作用，但浓度高且无药理学作用。考虑到天然脂肪酸的特性，例如生物相容性，生物降解性以及癌细胞对细胞吸收的增加，似乎将它们与药物结合可以改善其生物利用度，从而改善细胞毒性。因此，本研究的目的是将CP与饱和和不饱和脂肪酸偶联，并评估它们在人原发性（SW480）和转移性（SW620）结肠癌，转移性癌中的细胞毒性，凋亡诱导作用以及IL-6释放的抑制作用。前列腺癌（PC3）和正常（HaCaT）细胞系。PC3细胞系对获得的结合物最敏感。油酸共轭物（4）的IC50值为7.7μM，比单独的CP（101.4μM）低12倍。研究的衍生物在所有癌细胞系中诱导晚期凋亡，但在正常细胞中不诱导。最有效的凋亡诱导剂是缀合物4，其在晚期凋亡中导致PC3细胞的百分比最高（81.5％±3.9），其次是花生油酰胺5（75％±4.8）。DHA（8）和山梨酸（2）酸的结合物显示出对SW4
