Leishmaniasis represents a series of severe neglected tropical diseases caused by protozoa of the genus Leishmania and is widely distributed around the world. Here, we present the syntheses of Morita-Baylis-Hillman adducts (MBHAs) prepared from eugenol, thymol and carvacrol, and their bioevaluation against promastigotes of Leishmania amazonensis. The new MBHAs are prepared in two steps from ess...

Pentavalent antimony, as meglumine antimoniate (Glucantime) or sodium stibogluconate (Pentostam), is the main treatment for leishmaniasis, a complex of diseases caused by the protozoan Leishmania, and an endemic and neglected threat in Brazil. Despite over half a century of clinical use, their mechanism of action, toxicity and pharmacokinetic data remain unknown. The analytical methods for de...

The current article reports the case of a 19-month-old-girl, from the state of Minas Gerais, Brazil, with visceral leishmaniasis, by Leishmania (Viannia) braziliensis, and Human Immunodeficiency Virus (HIV) co-infection. The child's mother and father, aged 22 and 27 years old, respectively, were both HIV positive. The child was admitted to the General Pediatric Center, in Belo Horizonte, presen...

The stem barks of Pera benensis are employed by the Chimane Indians in the Bolivian Amazonia as treatment of cutaneous leishmaniasis caused by the protozoan Leishmania braziliensis. The chloroform extracts containing quinones were found active against the promastigote forms of Leishmania and the epimastigote forms of Trypanosoma cruzi at 10 micrograms ml-1. The activity guided fractionation of ...

Leishmaniasis is a neglected disease that is increasing globally at an alarming rate. Glucantime has been the therapy of choice for more than 50 years. A recent study reported the antileishmanial activity of copaiba oil against Leishmania amazonensis. These results led us to investigate morphological and ultrastructural changes in L. amazonensis treated with copaiba oil, using electron microsco...

background and objectives: current chemotherapies of cutaneous leihmaniasis have faced to some problems and limitations; development of new leishmanicidal drugs from different sources like herbal plants, are crucially important. the objective of the present study was evaluation of in vitro activity of alkanna frigida extracts in comparison with glucantime against leishmania major . materials an...

Background: Leishmaniasis is a parasitic disease that occurs in subtropical and tropical regions with approximately 350 million people worldwide 2 new cases annually. The annual increase cutaneous leishmaniasis (CL) observed, especially endemic areas such as Iran. Since there no effective vaccine, the detection of natural anti-leishmanial products essential. Objective: purpose this study was to...
