  Synthesis and Structure–Activity Relationships of New Quinolone-Type Molecules against Trypanosoma brucei

  摘要：

  Human African trypanosomiasis (HAT) or sleeping sickness is caused by two subspecies of Trypanosoma brucei, Trypanosoma brucei gambiense, and Trypanosoma brucei rhodesiense and is one of Africa's old plagues. It causes a huge number of infections and cases of death per year because, apart from limited access to health services, only inefficient chemotherapy is available. Since it was reported that quinolones such as ciprofloxacin show antitrypanosomal activity, a novel quinolone-type library was synthesized and tested. The biological evaluation illustrated that 4-quinolones with a benzylamide function in position 3 and cyclic or acyclic amines in position 7 exhibit high antitrypanosomal activity. Structure-activity relationships (SAR) are established to identify essential structural elements. This analysis led to lead structure 29, which exhibits promising in vitro activity against T. b. brucei (IC50 = 47 nM) and T. b. rhodesiense (IC50 = 9 nM) combined with low cytotoxicity against macrophages J774.1. Screening for morphological changes of trypanosomes treated with compounds 19 and 29 suggested differences in the morphology of mitochondria of treated cells compared to those of untreated cells. Segregation of the kinetoplast is hampered in trypanosomes treated with these compounds; however, topoisomerase II is probably not the main drug target.

  通过硝酸盐单硝化芳族化合物

  摘要：

  带有碱性氮原子的芳族化合物可以转化为相应的硝酸盐。化合物的单硝化反应可以通过将盐的二氯甲烷溶液添加到硫酸中，或将乙酰氯（或三氟乙酸酐）添加到盐的二氯甲烷溶液中来进行。除其他优点外，该协议还提供了最方便，最可靠的方式来防止硝化过度/欠燃，尤其适用于规模放大。
