1. In vitro antiparasitic activity and chemical composition of the essential oil from Protium ovatum leaves (Burceraceae)
ABSTRACT Leishmaniasis and trypanosomiasis are globally widespread parasitic diseases which have been responsible for high mortality rates. Since drugs available for their treatment are highly hepatotoxic, nephrotoxic and cardiotoxic, adherence to therapy has been affected. Thus, the search for new, more effective and safer drugs for the treatment of these d

3. In vitro anti-Leishmania infantum activity of essential oil from Piper angustifolium
Abstract Piper angustifolium Lam., Piperaceae, popularly known as "matito", "pimenta-de-macaco", "pimenta-longa" or "jagurandi" in Brazil, has been commonly used in the treatment of cutaneous leishmaniasis-associated lesions, but there are few studies on the activity against visceral leishmaniasis-associated species. This study demonstrates the first in vitr

4. Complexos metálicos de hidrazonas, tiossemicarbazonas e lapachol: atividade farmacológica e avaliação de relações estrutura-atividade
The present work comprises the synthesis and characterization of metal compounds with bioactive ligands and the study of their pharmacological profile. Anti-inflammatory, antimicrobial, antiparasitic and antitumor drug candidates were designed. Complex [Zn(LASSBio-466)H2O]2 was synthesized with salicylaldehyde-2-chlorobenzoyl hydrazone (H2LASSBio-466), while

6. Bioprospecção de plantas com potencial farmacológico para o tratamento das leishmanioses / Bioprospecting of plants with pharmacological potential for the treatment of leishmaniasis.
As leishmanioses são doenças causadas por protozoários do gênero Leishmania que acometem milhões de pessoas em todo o mundo. Apresentam manifestações clínicas que variam de lesões cutâneas, mucocutâneas a forma visceral, geralmente fatal. Antimoniais pentavalentes são as drogas de primeira escolha para o tratamento das leishmanioses, porém são

7. A atividade da pterocarpanoquinona LQB 118 in vitro e in vivo em Leishmania braziliensis / Activity of pterocarpanoquinone LQB 118 in vitro and in vivo in Leishmania braziliensis
As leishmanioses estão entre as mais importantes endemias brasileiras e encontram-se entre as doenças mais negligenciadas no mundo. O arsenal terapêutico disponível é restrito, tóxico, caro e em algumas situações ineficazes, devido ao surgimento de cepas resistentes do parasito. No Brasil são registrados anualmente mais de 20 mil casos de leishmanio

8. Miltefosine induces metacaspase and PARP genes expression in Leishmania infantum
OBJECTIVES: Apoptosis is the process of programmed cell death (PCD) that occurs in both animal and plant cells. Protozoan parasites possess metacaspase and these caspase-related proteases could be involved in the PCD pathways in these organisms. Therefore we analyzed the activities of metacaspase and PARP genes in Leishmania infantum (MCAN/IR/96/LON49) treat

10. Synthesis of 8.O.4 neolignans, derivatives and active analogues in Leishmania / Sintese de neolignanas 8.O.4 , derivados e analogos ativos em Leishmania
Neolignans and lignans present significant biological and pharmacological activities. Chemically lignans are dimers derived from the oxidative coupling of cinnamic and/or cinnamyl alcohol, while neolignans derive from allyl and/or propenyl phenols. In this work, the synthesis of neolignans and correlated substances resulted from the condensation reactions be
