  • An efficient synthesis of substituted cytosines and purines under focused microwave irradiation
    作者:Ling-Kuen Huang、Yen-Chih Cherng、Yann-Ru Cheng、Jing-Pei Jang、Yi-Ling Chao、Yie-Jia Cherng

  • Effect of O6-Substituted Guanine Analogs on O6-methylguanine DNA-methyltransferase Expression and Glioblastoma Cells Viability
    作者:Patrick-Denis St-Coeur、Marc Cormier、Veronique LeBlanc、Pier Morin、Mohamed Touaibia
    DOI:10.2174/1573406412666160710210907
    日期:2016.12.22
    Background: Glioblastoma multiforme (GBM) is often associated with a poor survival prognostic for patients. The main reason seems to be the acquired or inherent resistance to the chemotherapeutic agent used to treat the tumor, temozolomide (TMZ). To this day, the most recognized pathway of resistance is the DNA Direct Repair pathway by the means of the protein O6- methylguanine DNA-methyltransferase (MGMT). Objectives: To design and synthesize a series of MGMT inhibitors that can sensitize GBM cells to TMZ. Methods: Twenty-five O6-alkyl, O6-aryl and O6-substituted-aryl guanine analogs including nine novel compounds were synthesized, characterized, analyzed by molecular docking and tested on the T98G GBM cells viability. Results: Following molecular modeling with MGMT, the newly designed compounds 19, 22, and 24 emerged as the most promising MGMT ligands and displayed modest cytotoxicity. Guanine analog (19), bearing a p-nitrobenzyl moiety, reduced considerably the O6-methylguanine DNAmethyltransferase expression level. When combined with TMZ (1), which is used as first line treatment for brain tumors, compounds 19, 22, and 24 decreased T98G cellsproliferation by 32%, 68% and 50%, respectively. TMZ (1) displayed negligible effect on the proliferation of these cells further supporting the notion that this cell model is resistant to this alkylating agent. Conclusion: Overall, these results notably highlight a group of MGMT inhibitors that warrants further exploration in the development of therapeutic options to circumvent TMZ resistance in brain tumors.
    背景:胶质母细胞瘤(GBM)通常与患者的生存预后不良相关。主要原因似乎是患者对用于治疗该肿瘤的化疗药物替莫唑胺(TMZ)产生了获得性或固有的耐药性。迄今为止,最被认可的耐药途径是通过O6-甲基鸟嘌呤DNA甲基转移酶(MGMT)进行的直接DNA修复途径。 目的:设计并合成一系列MGMT抑制剂,以增强GBM细胞对TMZ的敏感性。 方法:合成了二十五个O6-烷基、O6-芳基和O6-取代芳基鸟嘌呤类似物,包括九个新化合物,并对它们进行了表征、分子对接分析,并在T98G GBM细胞上测试了其细胞毒性。 结果:通过与MGMT的分子建模,新设计的化合物19、22和24成为最有前景的MGMT配体,并显示出适度的细胞毒性。含有对硝基苄基的鸟嘌呤类似物(19)显著降低了O6-甲基鸟嘌呤DNA甲基转移酶的表达水平。当与用于脑肿瘤一线治疗的TMZ(1)联合使用时,化合物19、22和24分别使T98G细胞的增殖减少了32%、68%和50%。TMZ(1)对这些细胞的增殖显示出微弱的影响,这进一步支持了这种细胞模型对这种烷基化剂具有耐药性的观点。 结论:总的来说,这些结果显著突出了一些值得进一步探索的MGMT抑制剂,以开发克服脑肿瘤中TMZ耐药性的治疗方案。

  • 6-Oxo and 6-thio purine analogs as antimycobacterial agents
    作者:Ashish K. Pathak、Vibha Pathak、Lainne E. Seitz、William J. Suling、Robert C. Reynolds

    6-Oxo and 6-thio analogs of purine were prepared based on the initial activity screening of a small, diverse purine library against Mycobacterium tuberculosis (Mtb). Certain 6-oxo and 6-thio-substituted purine analogs described herein showed moderate to good inhibitory activity. N-9-substitution apparently enhances the anti-mycobacterial activity in the purine series described herein. Several 2-amino and 2-chloro purine analogs were also synthesized that showed moderate inhibitory activity against Mtb. (C) 2013 Elsevier Ltd. All rights reserved.
