  A series of new 2-aminonaphthoquinones and related compounds were synthesized and evaluated in vitro as trypanocidal and cytotoxic agents. Some tested compounds inhibited epimastigote growth and trypomastigote viability. Several compounds showed similar or higher activity and selectivity as compared with current trypanocidal drug, nifurtimox. Compound 4l exhibit higher selectivity than nifurtimox against

  合成了一系列新的2-氨基萘醌和相关化合物，并在体外评估了其为锥虫和细胞毒剂。一些经过测试的化合物抑制了前鞭毛体的生长和锥鞭毛体的生存能力。与目前的锥虫杀灭药硝呋替莫相比，几种化合物显示出相似或更高的活性和选择性。与Vero细胞相比，化合物4l对尼古丁对克鲁斯锥虫的选择性更高。测试了一些合成的醌类对癌细胞和正常成纤维细胞的影响，表明萘醌部分的某些化学修饰可诱导并显着提高细胞毒性的选择性指数（4g和10）。此处给出的结果表明，2-氨基萘醌衍生物的抗T. cruzi活性可以通过用吡啶部分取代苯环来提高。有趣的是，C-3上存在氯原子和高度亲脂性烷基或芳环是新近观察到的元素，应导致发现更具选择性的细胞毒性和锥虫性化合物。

  Background: A set of novel sulfanyl aminonaphthoquinone derivatives (5a-j) were synthesized starting from 2,3-dichloro-1,4-naphthoquinone (1). The amine substituents were introduced via a nucleophilic substitution at reflux temperature. Subsequent reactions of 2-chloro-3-arylamino-1,4-naphthoquinones (3a-d) with different thiols (4a-c) led to the formation of the desired amino-and thio-substituted products (5a-j).Methods: The purity and identity of the synthesized compounds were verified with IR, H-1 and C-13 NMR, and MS spectroscopy. In vitro antimicrobial activity was evaluated in a panel of seven bacterial strains (three Gram-positive and four Gram-negative bacteria) and one fungi with an additional study of antibiofilm activities. The anticancer activities of two selected compounds (5e and 5f) were evaluated against 60 human tumor cell lines derived from nine neoplastic diseases by National Cancer Institute (NCI).Results: As a result, compound (5e) was identified as a hit with antibacterial efficiency against human originated pathogens S. aureus with minimal inhibitory concentration (MIC) of 19.53 mu g/mL. When considering the antibiofilm activities of antibacterial molecule 5e against the S. aureus biofilms, the minimum biofilm eradication concentration (MBEC) value was 10000 mu g/mL. Concerning on anticancer activities, both compounds (5e and 5f) exhibited moderate anticancer activities on some of tumor cells, but no activity against normal peripheral blood mononuclear cells (PBMC). In addition, docking study was used to provide further insights into the experimental observations.Conclusion: Taken together, compound 5e could be considered as a promising starting point for further development.

  Several members of the phenylamino-1,4-naphthoquinone series were prepared in order to investigate structure-activity relationships (SAR) and to explore the antitumor effects associated with this scaffold. The cytotoxic effects of the aminoquinones (EC50) against a panel of cancer cell lines (MCF7, DU145 and T24 cells) and healthy fibroblasts (BALB/3T3) were assessed in vitro using the MTT reduction assay 48 h after drug exposure. SAR analysis of the aminonaphthoquinone series showed that insertion of a chlorine atom in the acceptor quinone nucleus and/or insertion of a methyl group at the nitrogen atom of the donor phenylamino group induced significant changes in cytotoxic activity. Quinones 7 and 9, which exhibited the highest selective indexes (5.73 and 6.29, respectively), were further characterized using the following assays: Colony formation, caspase-3 activity, and ATP content. The results showed that aminoquinone 7 strongly influenced ATP levels and impaired the proliferative capacity of T24 cells without activating caspase-3. (C) 2010 Elsevier Masson SAS.
