An organogold compound impairs Leishmania amazonensis amastigotes survival and delays lesion progression in murine cutaneous leishmaniasis: Mechanistic insights.

Leishmaniasis is one of the most important neglected diseases, classically characterized by three clinical forms that if left untreated can lead to skin lesions, lifelong scarring, or death depending on the parasite species. Unfortunately, treatment is unsatisfactory and the search for an improved therapy has been a priority. Gold compounds have emerged as promising candidates and among them, Au(I)bis-N-heterocyclic carbene (Au(BzTMX)) has stood out.

and Leishmanicidal Activity of Beauvericin.

Leishmaniasis is a worldwide disease caused by more than 20 species of parasites. and are among the main causative agents of cutaneous leishmaniasis, presenting a broad spectrum of clinical forms. As these pathologies lead to unsatisfactory treatment outcomes, the discovery of alternative chemotherapeutic options is urgently required.

Efficacy and safety of asunercept, a CD95L-selective inhibitor, in hospitalised patients with moderate-to-severe COVID-19: ASUNCTIS, a multicentre, randomised, open-label, controlled, phase 2 trial.

Background: The phase 2 ASUNCTIS study assessed the efficacy and safety of asunercept, a fully human CD95 (Fas) ligand-binding protein, in hospitalised patients with moderate-to-severe coronavirus disease (COVID-19) to assess the clinical benefit of CD95 ligand inhibition in this viral disease.

Methods: In this open-label, multicentre, randomised, controlled, phase 2 trial, patients with COVID-19-induced pneumonia and respiratory deterioration were randomly assigned (1:1:1:1) in 12 Russian and Spanish hospitals using an interactive web-response system to receive standard of care (SOC) or SOC plus weekly asunercept 25 mg, 100 mg, or 400 mg, administered intravenously for up to 4 weeks, or until hospital discharge or death. The randomisation was stratified according to the respiratory support methods at the time of enrolment, corresponding to categories 4-6 of a clinical severity assessment scale comprising 9 levels that was recommended by the World Health Organization (WHO) at the time of the study.
