Leishmanicidal drugs interacting stoichiometrically with parasite plasma membrane lipids, thus promoting permeability, have raised significant expectations for Leishmania chemotherapy due to their nil or very low induction of resistance. Inherent in this process is a decrease in intracellular ATP, either wasted by ionic pumps to restore membrane potential or directly leaked through larger membr...

fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

The aim of the present study was to explore the aerial parts of the Polygonatum verticillatum for various biological activities such as phytotoxic, insecticidal and leishmanicidal properties. Outstanding phytotoxicity was observed for the crude extract and its subsequent solvent fractions against Lemna acquinoctialis Welv at tested doses of 5, 50 and 500 μg/ml. Complete growth inhibition (100%)...

background and objectives: several natural compounds have been identified for the treatment ofleishmaniasis. due to a few safe drugs and the side effects caused by available chemotherapy, some new drugs for treatment of leishmaniasis are requested.  the genus pulicaria (asteraceae) is represented in the flora of iran by five species. phytochemical studies on pulicaria species have revealed some...

Leishmaniasis is considered one of the most untreated tropical diseases in world. In this study, we investigated vitro leishmanicidal activity and cytotoxicity various isolated lichen substances, including atranorin (1), usnic acid (2), gyrophoric (3), salazinic (4), galbinic (5), parietin (6), some semi-synthetic imine derivatives (7, 8, 9) (10, 11, 12, 13). Imine condensation reactions with h...
