Arylimidamides (AIAs) represent a new class of molecules that exhibit potent antileishmanial activity (50% inhibitory concentration [IC(50)], <1 microM) against both Leishmania donovani axenic amastigotes and intracellular Leishmania, the causative agent for human visceral leishmaniasis (VL). A systematic lead discovery program was employed to characterize in vitro and in vivo antileishmanial a...

background: the present study aimed to survey antileishmanial activity of methanolic holothuria leucospilota extract against leishmania major promastigotes in vitro. methods: promastigotes were cultured in rpmi 1640 and after reaching the stationary phase, the study was conducted with different concentrations of the extract. afterwards, mtt colorimetric assay for the obtaining of 50% inhibitory...

Three known compounds including, uracil (1), 5-methyl (2) and uridine (3) have been isolated from the soft coral Litophyton arboreum collected red sea. The were identified using spectroscopic techniques predominately 1H-NMR 13C-NMR analyses, in addition to HR-ESI-MS. Moreover, 1-3 vitro estimated for their cytotoxic activity against three human cancer cell lines (A549, MCF-7 HepG2), antileishma...

BACKGROUND In the absence of vaccines and limitations of currently available chemotherapy, development of safe and efficacious drugs is urgently needed for visceral leishmaniasis (VL) that is fatal, if left untreated. Earlier we reported in vitro apoptotic antileishmanial activity of n-hexane fractions of Artemisia annua leaves (AAL) and seeds (AAS) against Leishmania donovani. In the present s...

BACKGROUND Leishmaniasis is the world's second deadliest parasitic disease after malaria, and current treatment of the different forms of this disease is far from satisfactory. Alkylphospholipid analogs (APLs) are a family of anticancer drugs that show antileishmanial activity, including the first oral drug (miltefosine) for leishmaniasis and drugs in preclinical/clinical oncology trials, but t...

Leishmaniasis is endemic in 98 countries and territories worldwide. The therapies available for leishmaniasis have serious side effects, thus prompting the search for new therapies. The present study investigated the antileishmanial activities of 2,3-diarylsubstituted quinoxaline derivatives against Leishmania amazonensis The antiproliferative activities of 6,7-dichloro-2,3-diphenylquinoxaline ...
