Abstract

A series of novel pyrazolyl amide-chalcones conjugates was synthesized in five steps and evaluated against a range of medically important kinetoplastid parasites including Trypanosoma cruzi, Trypanosoma brucei brucei, Trypanosoma brucei rhodesiense and Leishmania infantum. In addition, the series was also tested for in vitro cytotoxicity activity against human lung fibroblasts and primary mouse macrophages. Among all synthetised compounds, 9b was found to be the most active against T. b. brucei with an IC50 value of 0.51 ± 0.06 μM. Against T. b. rhodesiense, 9n was found to be the most potent with an IC50 value of 0.46 ± 0.07 μM. While against L. infantum, 9a was found to be most active with an IC50 value of 7.16 ± 1.88 μM. Based on the results and SAR, further modifications will be carried out to increase potency.

吡唑酰胺-查耳酮共轭物:合成与抗原生动物活性。
通过五个步骤合成了一系列新型吡唑酰胺-查耳酮共轭物,并评估了这些共轭物对一系列医学上重要的动植体寄生虫(包括克鲁斯锥虫、布鲁西锥虫、罗得西亚布鲁西锥虫和婴儿利什曼原虫)的毒性。此外,还测试了该系列化合物对人肺成纤维细胞和小鼠原代巨噬细胞的体外细胞毒性活性。结果发现,在所有合成化合物中,9b 对布氏杆菌的活性最高,其 IC50 值为 0.51 ± 0.06 μM。9n 对布氏杆菌的作用最强,其 IC50 值为 0.46 ± 0.07 μM。而 9a 对幼虫的活性最强,IC50 值为 7.16 ± 1.88 μM。根据研究结果和 SAR,我们将对 9a 进行进一步改造,以提高其药效。

期刊介绍: Naunyn-Schmiedeberg''s Archives of Pharmacology was founded in 1873 by B. Naunyn, O. Schmiedeberg and E. Klebs as Archiv für experimentelle Pathologie und Pharmakologie, is the offical journal of the German Society of Experimental and Clinical Pharmacology and Toxicology (Deutsche Gesellschaft für experimentelle und klinische Pharmakologie und Toxikologie, DGPT) and the Sphingolipid Club. The journal publishes invited reviews, original articles, short communications and meeting reports and appears monthly. Naunyn-Schmiedeberg''s Archives of Pharmacology welcomes manuscripts for consideration of publication that report new and significant information on drug action and toxicity of chemical compounds. Thus, its scope covers all fields of experimental and clinical pharmacology as well as toxicology and includes studies in the fields of neuropharmacology and cardiovascular pharmacology as well as those describing drug actions at the cellular, biochemical and molecular levels. Moreover, submission of clinical trials with healthy volunteers or patients is encouraged. Short communications provide a means for rapid publication of significant findings of current interest that represent a conceptual advance in the field.
