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。
