  Design of antiangiogenic hypoxic cell radiosensitizers: 2-Nitroimidazoles containing a 2-aminomethylene-4-cyclopentene-1,3-dione moiety

  摘要：

  We designed chiral 2-nitroimidazole derivatives containing a 2-aminomethylene- 4-cyclopentene-1,3-dione moiety as antiangiogenic hypoxic cell radiosensitizers. Based on results of molecular orbital calculations, the 2-aminomethylene-4-cyclopentene1,3-dione moiety is expected to show high electrophilicity comparable to that of the 2-methylene-4-cyclopentene-1,3-dione moiety included in TX-1123 and tyrphostin AG17. We evaluated the antiangiogenic and radiosensitizing effects of the new compounds, along with other biological properties including their activities as hypoxic cytotoxicities and protein tyrosine kinase (PTK) inhibitory activities. Among the compounds tested, 5 (TX-2036) proved to be the strongest antiangiogenic hypoxic cell radiosensitizer. All the other chiral 2-nitroimidazole derivatives having 2-aminomethylene-4-cyclopentene-1,3-dione moiety tested were also antiangiogenic hypoxic cell radiosensitizers. The PTK inhibitory activity of 5 (TX-2036) showed this to be a promising and potent EGFR kinase inhibitor, having an IC50 value of lower than 2 mu M. This compound also was an Flt-1 kinase inhibitor having an IC50 value of lower than 20 mu M. Our results show that these chiral 2- nitroimidazole derivatives that contain the 2- aminomethylene-4- cyclopentene1,3-dione moiety as a potent antiangiogenic pharmacophoric descriptor are promising lead candidates for the development of antiangiogenic hypoxic cell radiosensitizers.

  (S)-和 (R)-咪唑作为 GPX 抑制剂的评价：合成、表征，包括圆二色性和牛 GPx-1 的体外测试

  摘要：

  外消旋米索尼达唑是一种正式用于癌症放射治疗的放射增敏剂，至今仍在使用，曾被报道对小鼠谷胱甘肽过氧化物酶 (GPX) 表现出强烈的抑制作用。这似乎使米索尼达唑成为开发新型 GPX 抑制剂的先导结构，以在化疗耐药肿瘤中引起氧化应激。米索尼达唑作为 GPX 抑制剂的一个独特特征是不存在硫醇官能团。因此，有望选择性地靶向抑制，而不会与阳离子和巯基发生混杂的相互作用。我们合成了米索尼达唑的异构体，并分析了手性高效液相色谱 (HPLC) 鉴定特定对映体的能力。由于手性池合成，可以验证正确配置的分配。最后，我们评估了两种异构体对牛红细胞 GPx-1 的抑制活性，GPx-1 与人类酶有 87% 的同源性。尽管先前报道了消旋咪唑对同源性较低的小鼠 GPx-1 的抑制作用，但我们没有发现任何一种异构体对牛酶的任何显着抑制活性。尽管米索尼达唑似乎不太可能是人类 GPx-1 活性的抑制剂，但我们仍然将米索尼达唑作

  (R)- and (S)-Epichlorohydrins were used to prepare the enantiomers of sterically diverse haloacetylcarbamoyl-2-nitroimidazoles that function as hypoxic cell radiosensitizers. The synthetic design allowed for introduction of a side chain of varying bulk that permitted an examination of the steric effects on enantio-discrimination in biological assay systems. The single stereocenter also connected the two pharmacophores-a 2-nitroimidazole moiety critical to hypoxic cell radiosensitization, and a haloacetylcarbamoyl group to function as an anti-angiogenesis pharmacophore. In the chick embryo chorioallantoic membrane (CAM) assay, the R-enantiomers possessing the bulky p-tert-butylphenyl group showed higher anti-angiogenic activity than the corresponding S-enantiomers, while there were no differences in the activity between the enantiomers containing the less bulky methyl and tert-butyl groups. Among the compounds we report, R-p-tert-butylphenyl-bromoacetylcarbamoyl-2-nitroimidazole, TX-1898, was found to be the most promising candidate for further development of as anti-angiogenic hypoxic cell radiosensitizer.
