<dcterms:abstract xml:lang="fr">L'étude des médicaments efficaces, de leurs mécanismes et de leurs cibles a été cruciale tout au long du dernier siècle. Nous observons maintenant l'évolution de la recherche pharmaceutique, passant des découvertes fortuites au développement systématique. Le besoin urgent de médicaments ciblant les maladies sans nuire aux hôtes souligne l'importance d'identifier des stratégies de traitement précises. Le ribosome s'est révélé être une cible précieuse contre les infections bactériennes. Récemment, le champ d'investigation s'est étendu des ribosomes procaryotes aux ribosomes eucaryotes. Cette étude se concentre sur la compréhension des modes de liaison des petites molécules au ribosome eucaryote. Un objectif primordial est le développement d'un protocole novateur de cristallisation du ribosome eucaryote de Candida albicans. De plus, des composés divers ont été analysés grâce aux techniques de diffraction X et de cryo-microscopie électronique, incluant les aminoglycosides et leurs complexes avec des activateurs de lecture, ainsi que les médicaments anticancéreux et antipathogènes. Cette étude offre un aperçu des effets combinés des aminoglycosides et des activateurs de lecture, associé à des détails pratiques sur la liaison de divers composés qui pourraient être précieux pour le développement ultérieur de médicaments.</dcterms:abstract>
<dcterms:abstract xml:lang="en">Studying effective drugs, their mechanisms, and targets has been pivotal throughout the last century. We now observe the evolution of drug investigation from chance discoveries to systematic development. The urgent need for medications that target diseases without harming hosts underscores the importance of identifying precise treatment strategies. The ribosome has emerged as a valuable target against bacterial infections. Recently, the focus has extended from prokaryotic to eukaryotic ribosomes.This study centers on comprehending the binding modes of small molecules to the eukaryotic ribosome. A primary objective is the development of an innovative crystallization protocol for the eukaryotic ribosome from Candida albicans. Moreover, diverse compounds were analyzed using X-ray and cryo-EM techniques, encompassing aminoglycosides and their complexes with readthrough enhancers, as well as anticancer and antipathogenic drugs. The study offers insights into the combined effects of aminoglycosides and readthrough enhancers, coupled with practical binding details of various compounds that could be valuable for further drug development.</dcterms:abstract>
