THE ANTILEISHMANIAL ACTIVITY OF THREE ORGANIC SOLVENT EXTRACTS AND WATER RESIDUE OF THE PLANTS: Acacia nilotica (Mimosaceae) (husk), Ambrosia miratima (Astraceae) (aerial shoot) and Azadarichta indica (Meliaceae) (leaves) were tested in vitro against Leishmania donovani promastigotes. The study revealed that the extracts of A. nilotica and A. miratima have effectious antileishmanial activity at...

Benzimidazole is a bicyclic heterocyclic aromatic compound in which benzene fused to imidazole moiety. holds vital role the field of medicinal chemistry possesses wide variety pharmacological activities like antibacterial, anti cancer, antifungal, antileishmanial, tubercular, viral and malarial respectively, hence benzimidazole moiety attracting chemist synthesize different derivatives with act...

Hypocrellins A and B were evaluated for in vitro antimicrobial and antileishmanial activities. Hypocrellin A exhibited promising activity against Candida albicans and moderate activity against Staphylococcus aureus, methicillin-resistant S. aureus, Pseudomonas aeruginosa, and Mycobacterium intracellulare. Hypocrellin B showed weak antimicrobial activities. Hypocrellin A exhibited potent antilei...

BACKGROUND Leishmaniasis is a neglected tropical parasitic diseases affecting millions of people around the globe. Quinazolines are a group of compounds with diverse pharmacological activities. Owing to their promising antileishmanial activities, some 3-aryl-2-(substitutedstyryl)-4(3H)-quinazolinones were synthesized in good yields (65.2% to 86.4%). RESULTS The target compounds were synthesiz...

Transgenic Leishmania infantum promastigotes, which constitutively express green fluorescent protein (GFP) in their cytoplasm, were used to monitor the effects of antileishmanial compounds in real time. The GFP-based assay provided a reliable measure of drug-induced inhibitory effects on protein expression, resulting in a dynamic picture of the responses of leishmanial promastigotes to the comp...

Recombinant granulocyte/macrophage colony-stimulating factor (rGM-CSF) obtained from cloned complementary Mo cell DNA and expressed in COS-1 cells activates cultured peripheral blood monocyte-derived macrophages in vitro to become cytotoxic for intracellular L. donovani. The antileishmanial effect of rGM-CSF, which can be completely neutralized by anti-rGM-CSF antiserum, is maximal after 36 h p...

Vitis vinifera L.is a traditional Asian herb widely used for different health problems. In thepresent research, the ethanolic and the aqueous extracts of Vitis vinifera L. leaves collected fromshrub, grown in Tunisia, were prepared and evaluated for the antileishmanial activity againstLeishmani ainfantum promastigotes. The inhibitory concentration 50 (IC50) was determined andthe results showed ...

Synthesis of Silver Nanoparticles using Methanol Extract Bunium Persicum and the Evaluation its Cytotoxic, Antileishmanial, Antimicrobial Activities

Leishmania species are parasites that multiply within phagocytes and cause several clinical diseases characterized by single or multiple ulcerations. One of the complications that can induce tissue damage and the resulting scars is caused by secondary bacterial infections. Studies to find new, effective, and safe oral drugs for treating leishmaniasis are being conducted since several decades, o...
