چکیده
As pterocarpanquinonas 8a-c, previamente sintetizadas em nosso laboratório, e uma série homóloga de derivados, substâncias 9a-c preparadas neste trabalho, foram avaliadas em células de câncer de mama (MCF-7) e em cultura dos parasitas Leishmania amazonensis e Plasmodium falciparum. As substâncias 8a-c foram mais potentes que 9a-c nas células tumorais e em Leishmania amazonensis. Por outro lado, 9a-c mostraram ser as mais ativas sobre o Plasmodium falciparum. Todas as substâncias estudadas foram biosseletivas, apresentando baixa citotoxicidade para linfócitos murinos frescos e linfócitos humanos ativados pelo mitógeno fitoemoaglutinina (PHA).

Thiadiazoles: the appropriate pharmacological scaffolds with leishmanicidal and antimalarial activities: a review
Leishmaniasis and malaria are serious public health problems in tropical and sub-tropical regions worldwide. Development of drug-resistant strains has disrupted efforts to control the spread of these diseases in the world. The conventional antiparasitic chemotherapy still suffers from side effects and drug resistance. Therefore, the development of novel antimalarial and leishmanicidal drugs rem...
متن کاملIn-vitro evaluation of antileishmanial activity and toxicity of artemether with focus on its apoptotic effect
Artemisinin and its derivatives are very important new class of antimalarial drugs. One of the most important artemisinin derivatives is artemether. The antiparasitic activity of artemether as a derivative of artemisinin is related to endoperoxide bridge in its structure. The aim of this study was the evaluation of antileishmanial effect of artemether, with more focus on its apoptotic effect. I...

متن کاملDesign, ADME Evaluation, Lewis Acid Catalysed Synthesis and Biological Evaluation of 1,4 Naphthoquinone Derivatives as Antimalarial Agents
In an effort to develop new antimalarials, some 1,4 naphthoquinone derivatives were designed on the basis of results of computational studies reported in previous paper, which showed that 2 nd or 3 rd or both position of 1,4 naphthoquinone is most suitable for better antimalarial activity. When the reaction of 1,4 naphthoquinone was performed without a catalyst several secondary products were f...

Quinones such as 1,4-naphthoquinones are abundant in nature and naphthoquinone based natural products are known to possess anticancer activity. This pharmacophore is known to convey anticancer activity to some drugs such as streptonigrin, mitomycin A, etc. We synthesized and characterized different classes of naphthoquinone derivatives including bis naphthoquinone, 2-arylaminonaphthoquinone, be...
