Vitis vinifera L.is a traditional Asian herb widely used for different health problems. In the present research, the ethanolic and the aqueous extracts of Vitis vinifera L. leaves collected from shrub, grown in Tunisia, were prepared and evaluated for the antileishmanial activity against Leishmani ainfantum promastigotes. The inhibitory concentration 50 (IC50) was determined and the results sho...
The objective of the present study was to evaluate in vitro antileishmanial activity of leaves form Plumeria pudica Jacq. (Apocynaceae). In the present study, the in vitro antileishmanial activity of petroleum ether, chloroform and methanol extracts from P. pudica leaf was evaluated against Leishmania donovani (strain AG 83) promastigotes by in vitro promastigote cell toxicity assay by using MT...
This work describes the synthesis of a series of quaternary ammonium salts and the assessment of their in vitro antileishmanial activity and cytotoxicity. A preliminary discussion on a structure-activity relationship of the compounds is also included. Three series of quaternary ammonium salts were prepared: (i) halomethylated quaternary ammonium salts (series I); (ii) non-halogenated quaternary...
Cutaneous leishmaniasis (CL) is a neglected tropical disease, which causes severe skin lesions. Due to the lack of effective vaccines, and toxicity or reduced effectiveness of available drugs in addition to complex and prolonged treatments, there is an urgent need to develop alternatives for the treatment for CL with different mechanisms of action. In our effort to search for new promising hits...
OBJECTIVES We have previously demonstrated the immunomodulatory effects of physalins, secosteroids purified from Physalis angulata. Here we investigate the antileishmanial activity of physalins in vitro and in vivo in a model of cutaneous leishmaniasis. METHODS The antileishmanial activity of physalins B, D and F was tested in Leishmania-infected macrophage cultures. For the in vivo studies, ...
The antileishmanial activity of extracts and phytoconstituents of Moringa oleifera Lam. was investigated in vitro against promastigotes of Leishmania donavani. The 70% ethanolic extract of roots and the methanolic extract of leaves showed moderate inhibitory activity with IC50 values of 83.0 microg/ml and 47.5 microg/ml, respectively. Antileishmanial activity of the methanolic extract of leaves...
In a previous works searching for new drugs with high efficiency, we reported the in vitro and in vivo antileishmanial activity of a series of diarylheptanoid structurally related to curcumin against L. amazonensis. This work describes the in vitro antileishmanial activity of a new series of diarylheptanoids and diarylpentanoids derivatives. These drugs were assayed against Leishmania amazonens...
We describe herein the synthesis and antileishmanial activity of 1,3-bis(aryloxy)propan-2-ols. Five compounds (2, 3, 13, 17, and 18) exhibited an effective antileishmanial activity against stationary promastigote forms of Leishmania amazonensis (IC50 < 15.0 μm), and an influence of compound lipophilicity on activity was suggested. Most of the compounds were poorly selective, as they showed tox...
