A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...

Low oxygen environments and accumulation of hypoxia-inducible factors (HIFs) are features of infected and inflamed tissues. Here, we summarize our current knowledge on oxygen levels found in Leishmania-infected tissues and discuss which mechanisms potentially contribute to local tissue oxygenation in leishmanial lesions. Moreover, we review the role of hypoxia and HIF-1 on innate antileishmania...

objective(s):solanum acueastrum dunal.has been shown to have some chemotherapeutic value. leaf and berry water and methanol compounds of s. acueastrum were evaluated for possible antileishmanial activity in vivo on balb/c mice and in vitro against leishmania major promastigotes, amastigotes and vero cells.  materials and methods: dry s. aculeastrum berry and leaf material were extracted in meth...

The presence of an RNA virus in a South American subgenus of the Leishmania parasite, L. (Viannia), was detected several decades ago but its role in leishmanial virulence and metastasis was only recently described. In Leishmania guyanensis, the nucleic acid of Leishmania RNA virus (LRV1) acts as a potent innate immunogen, eliciting a hyper-inflammatory immune response through toll-like receptor...

Leishmaniasis is one of the most diverse and complex vector-borne metazoonosis diseases[1]. The causing agent is at least 17 species[2] of obligate intracellular protozoan parasites that belong to the genus Leishmania[3]. It is transmitted to human by the bite of phlebotomine female sand flies of the genera Phlebotomus and Lutzomyia in the old and new worlds respectively[4]. The species are in ...

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...
