Background: Despite the progress achieved by anti-retroviral drug research in the last decades, the discovery of novel compounds endowed with selective antiviral activity and reduced side effects is still a necessity. At present, the most urgent requirement includes the improvement of HIV (Human Immunodeficiency Virus) prevention and sexual transmission and the development of new drugs to treat the chronic lifelong infection. Methods: Six chloro-1,4-dimethyl-9H-carbazoles (2a,b–4a,b) have been prepared following opportunely modified known chemical procedures and tested in luciferase and Escherichia coli β-galactosidase expressing CD4+, CXCR4+, CCR5+ TZM-bl cells. Results and Conclusion: a preliminary biological investigation on the synthesized small series of chloro-1,4-dimethyl-9H-carbazoles has been carried out. Among all tested compounds, a nitro-derivative (3b) showed the most interesting profile representing a suitable lead for the development of novel anti-HIV drugs.
背景:尽管在过去几十年中抗逆转录病毒药物研究取得了进展,但仍然需要发现具有选择性抗病毒活性和减少副作用的新化合物。目前,最紧迫的需求包括改善HIV(人类免疫缺陷病毒)的预防和性传播,以及开发新药以治疗终身慢性感染。方法:制备了六种氯代-1,4-二甲基-9H-咔唑(2a,b–4a,b),采用适当修改的已知化学程序,并在表达CD4+、CXCR4+、CCR5+的TZM-bl细胞中测试其在荧光素酶和大肠杆菌β-半乳糖苷酶中的活性。结果与结论:对合成的小系列氯代-1,4-二甲基-9H-咔唑进行了初步生物研究。在所有测试化合物中,一种硝基衍生物(3b)的表现最为引人注目,展现出适合于新型抗HIV药物开发的潜力。
