The surface charge of trypanosomatids

open access: yesAnais da Academia Brasileira de Ciências, 2002
The surface charge of trypanosomatids was evaluated by means of the binding of cationic particles, as visualized by electron microscopy and by direct measurements of the electrophoretic mobility of cells.

Pre-mRNA trans-splicing: from kinetoplastids to mammals, an easy language for life diversity

open access: yesMemorias do Instituto Oswaldo Cruz, 2005
Since the discovery that genes are split into intron and exons, the studies of the mechanisms involved in splicing pointed to presence of consensus signals in an attempt to generalize the process for all living cells. However, as discussed in the present

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

Identification of a Benzenesulfonylpiperazine Derivative With In Vivo Efficacy Against Visceral Leishmaniasis

open access: yesChemical Biology &Drug Design, Volume 108, Issue 2, August 2026.
This work highlights the satisfactory pharmacokinetic profile of two benzenesulfonylpiperazine lead candidates, followed by in vivo assessment in a murine model of visceral leishmaniasis. This assessment identified compound 2 as moderately active at a lower dose, but its efficacy increased at higher doses, though with concerns regarding safety.

A Stroll Through the History of Monoxenous Trypanosomatids Infection in Vertebrate Hosts

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
The Trypanosomatidae family encompasses unicellular flagellates and obligate parasites of invertebrates, vertebrates, and plants. Trypanosomatids are traditionally divided into heteroxenous, characterized by the alternation of the life cycle between an ...

Pyridyl‐Imidazopyridine Derivatives Displaying Submicromolar Activity Against Trypanosoma cruzi

open access: yesChemMedChem, Volume 21, Issue 13, 14 July 2026.
Previously reported pyridyl‐thiazoles and highly active imidazopyridines against Trypanosoma cruzi inspired the design of a new series of pyridyl‐substituted imidazopyridines. Among the synthesized compounds, 5h emerged as the most promising derivative, displaying potent trypanocidal activity (EC50 = 0.16 μM), excellent selectivity (SI > 1250), and ...

Synthesis, Electrochemistry, In Vitro Antiprotozoal Efficacy and Mechanistic Study of Novel ‘Ferrantoin’ and Related Derivatives

open access: yesApplied Organometallic Chemistry, Volume 40, Issue 7, July 2026.
1,2‐Disubstituted ferrocene analogues bearing hydantoin or rhodanine synthons were synthesised and assessed for antitrypanosomatid activity. An antileishmanial early lead, analogue 23, acting through ROS generation and hence oxidative stress, was uncovered.

Trypanosomatid Infections: How Do Parasites and Their Excreted–Secreted Factors Modulate the Inducible Metabolism of l-Arginine in Macrophages?

open access: yesFrontiers in Immunology, 2018
Mononuclear phagocytes (monocytes, dendritic cells, and macrophages) are among the first host cells to face intra- and extracellular protozoan parasites such as trypanosomatids, and significant expansion of macrophages has been observed in infected hosts.

Structural basis of ligand selectivity in FAD/NAD(P)H‐dependent dehydrogenases: insights from trypanothione reductase and type II NADH dehydrogenase

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract FAD/NAD(P)H‐dependent dehydrogenases form a structurally conserved family of redox enzymes that participate in essential metabolic processes across parasites and higher organisms. Among them, trypanothione reductase (TR) is a key component of the redox metabolism of Leishmania species and represents an attractive target for antileishmanial ...

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

open access: yesMedical and Veterinary Entomology, Volume 40, Issue 2, Page 350-359, June 2026.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...
