  Synthesis and leishmanicidal activities of 1-(4-X-phenyl)-N′-[(4-Y-phenyl)methylene]-1H-pyrazole-4-carbohydrazides

  摘要：

  1H-pyrazole-4-carbohydrazides were synthesized and their leishmanicidal in vitro activities and cytotoxic effects were investigated. The drugs prototypes of these new compounds (ketoconazole, benznidazole, allopurinol and pentamidine) were also tested. It was found that among all the 1H-pyrazole-4-carbohydrazides derivatives examined, the most active compounds were those with X = Br, Y = NO2 (27) and X = NO2, Y = Cl (15) derivatives which showed to be most effective on promastigotes forms of L. amazonensis than on L. chagasi and L. braziliensis species. When tested against murine peritoneal macrophages as mammalian host cell controls of toxicity, 1-(4-Br-phenyl)-N'-[(4-NO2-phenyl)methylene]-1H-pyrazole-4-carbohydrazides (27) (EC50 = 50 mu M 1(-1)) and 1-(4-NO2-phenyl)-N'-[(4-Cl-phenyl)methylene]-1H-pyrazole-4-carbohydrazides (15) EC50 = 80 mu M 1(-1))] was reasonably toxic. However, both compounds were less toxic than pentamidine and ketoconazole. These results provide new perspectives on the development of drugs with activities against Leishmania parasite.

  Chemotherapy for leishmaniasis, diseases caused by protozoa of the genus Leishmania, remains inefficient in several treatments. So there is a need to search for new drugs. In this work, we have synthesized 1-aryl-1H-pyrazole-4-carboximidamides derivatives and evaluated antileishmanial activities in vitro, as well as cytotoxic effects. Structure-activity relationship (SAR) studies were carried out with all the compounds of the series. Compound 2 showed an activity profile that can be improved through medicinal chemistry strategies.

  针对由利什曼原虫属寄生虫引起的利什曼病的化疗，在多种治疗中仍显低效。因此，寻找新药物变得十分必要。在本研究中，我们合成了1-芳基-1H-吡唑-4-羧酰亚胺衍生物，并对其抗利什曼活性进行了体外评估，同时也考察了其细胞毒性效应。我们对系列化合物进行了构效关系（SAR）研究。化合物2显示出一种活性特征，可通过药物化学策略进一步优化。

  Two series of quinoline derivatives containing pyrazole group were synthesized and characterized by means of 1H NMR, FT-IR, MS, elemental analysis and X-ray single crystal diffraction, and their UV–vis absorption behavior and fluorescence properties were also measured. Moreover, the effects of acetic acid and triethylamine on the spectroscopic properties of synthesized products were examined with compounds

  合成了两个含吡唑基的喹啉衍生物，并通过1 H NMR，FT-IR，MS，元素分析和X射线单晶衍射对其进行了表征，并测量了它们的紫外可见吸收性能和荧光性质。此外，用化合物3a和5a检验了乙酸和三乙胺对合成产物光谱性质的影响作为例子。已经发现，所有合成的喹啉衍生物在303nm处显示最大吸收峰并且在445nm附近显示发射峰。此外，乙酸和三乙胺均可改变介质的酸度，从而影响合成产品的紫外可见吸收光谱和荧光光谱。此外，理论研究表明，喹啉环的H +和N原子的整合有利于在乙酸存在下形成新产物，这种情况下获得的产物在400 nm处显示出新的UV-vis吸收峰。
