Synthesis and Antiparasitic Activities of New Organometallic Derivatives of the Benzimidazole Anthelmintic Drugs

open access: yesChemBioChem, Volume 27, Issue 15, 14 August 2026.
Organometallic derivatization of existing drugs is a common strategy to look for new drug candidates. This work describes the derivatization of the benzimidazole anthelmintic scaffold, from the synthesis of the organometallic derivatives to the evaluation of their biological properties. It highlights a broad range of antiparasitic activities and leaves

Leishmania infantum proteophosphoglycans regurgitated by the bite of its natural sand fly vector, Lutzomyia longipalpis, promote parasite establishment in mouse skin and skin-distant tissues

open access: yes, 2010
We demonstrate that a proteophosphoglycan-rich gel secreted by Leishmania infantum inside the midgut of Lutzomyia longipalpis sand flies (promastigote secretory gel) is regurgitated along with an average dose of 500 L.

Antileishmanial activity of polycyclic derivatives

open access: yesParasite, 2005
33 polycyclic derivatives have been studied and tested on Leishmania donovani and L. major promastigotes. Their antileishmanial activity was assessed in vitro and an assay of their cytotoxicity was realized on human myelomonocytic cell line.

Actinomycin Derivatives: Structural Diversification and Biological Activities

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

HetCA/STOCSY‐Guided Dereplication of Artemisia arborescens Reveals Furofuran Lignans with Antileishmanial Effects

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Bioactive metabolites can remain hidden in negligible activity extracts. A statistical spectroscopy–driven dereplication workflow integrating the HeteroCovariance Approach (HetCA) and Statistical Total Correlation Spectroscopy (STOCSY) prioritized furofuran lignans in Artemisia arborescens, identifying three compounds with moderate antileishmanial ...

The macrophage microtubule network acts as a key cellular controller of the intracellular fate of Leishmania infantum.

open access: yesPLoS Neglected Tropical Diseases, 2020
The parasitophorous vacuoles (PVs) that insulate Leishmania spp. in host macrophages are vacuolar compartments wherein promastigote forms differentiate into amastigote that are the replicative form of the parasite and are also more resistant to host ...

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 30, 14 August 2026.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.

NATURAL PROMASTIGOTE INFECTION OF SAND-FLIES AND ITS FIRST OCCURRENCE IN SERGENTOMYIA DENTATA IN ARDABIL PROVINCE, NORTH WEST OF IRAN [PDF]

open access: yesIranian Journal of Public Health, 1997
Visceral leishmanisasis is endemic and zoonotic in several foci in Ardabil province, North West of Iran. The main objective of this study was to determine the natural promastigote infection of sand-flies in active seasons, during 1991-1995.
