Piplartine as an Innovative Natural Product With Dual Antiparasitic and Immunomodulatory Actions

Journal of Immunology Research, Volume 2026, Issue 1, 2026.
Neglected tropical diseases (NTDs) remain a major global health burden, disproportionately affecting low‐ and middle‐income regions and demanding innovative therapeutic strategies. This review summarizes current evidence on piplartine (piperlongumine), a naturally occurring amide from Piper species with broad antiparasitic and immunomodulatory ...

Sequence analysis of the 3-untranslated region of HSP70 (type I) genes in the genus Leishmania: Its usefulness as a molecular marker for species identification [PDF]

, 2015
Background: The Leishmaniases are a group of clinically diverse diseases caused by parasites of the genus Leishmania. To distinguish between species is crucial for correct diagnosis and prognosis as well as for treatment decisions.

The P2X7 Receptor and Its Relation to Neglected Tropical Diseases: Focusing on Chagas Disease

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Chagas disease, caused by Trypanosoma cruzi, is a neglected tropical disease (NTD) that can lead to severe cardiac complications, including chronic Chagas cardiomyopathy. While NTDs are caused by a variety of pathogens—such as protozoa, bacteria, viruses, and helminths, Chagas disease remains underexplored, particularly regarding host immune responses.

Oxidative Stress Modulation and Antileishmanial Activity of Salvinia auriculata

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
Ethanolic extract of Salvinia auriculata showed significant antioxidant and antileishmanial activities. Salviniside II, the major metabolite, was isolated, structurally characterized, and evaluated, but exhibited weaker antiparasitic effects when compared to the whole extract.

DPPH‐based Antioxidant Screening and Cellulase‐assisted Hydrodistillation of Matourea azurea: Improved Essential Oil Yield and Density Functional Theory Insights Into a Rare Terpene

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Essential oils are rich in bioactive molecules like terpenes and phenolic compounds, but have low yields, making process efficiency crucial. Enzyme‐assisted hydrodistillation is a sustainable alternative, enhancing oil release by degrading the cell wall.

Fungal Biodiversity From the Atlantic Forest With Bioactive Metabolites Against Cutaneous Leishmaniasis

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT Biodiversity offers a rich source of bioactive compounds for drug discovery. We isolated Aspergillus fumigatus from compost in the Atlantic Forest and found its extract active against Leishmania (Leishmania) amazonensis. Two crude extracts, I06 and I75, were selected for further study.

Experimental mixed infection of Leishmania (Leishmania) amazonensis and Leishmania (L.) infantum in hamsters (Mesocricetus auratus)

Parasitology, 2017
SUMMARYIn South America, visceral leishmaniasis is frequently caused by Leishmania infantum and, at an unknown frequency, by Leishmania amazonensis. Therefore, mixed infections with these organisms are possible. Mixed infections might affect the clinical course, immune response, diagnosis, treatment and epidemiology of the disease. Here we describe the
