Ein neuer Malariawirkstoff hemmt die Proteinsynthese von Plasmodium falciparum

open access: yesAngewandte Chemie, Volume 137, Issue 49, December 1, 2025.
Die Verbindung 31 stellt einen vielversprechenden Ansatz für die Entwicklung eines Malariawirkstoffs mit einem starken Wirkungsprofil dar (PfNF54 IC50 ± s.d. = 3,9 ± 0,4 nM). Sie hat einen neuartigen Wirkmechanismus, indem sie an zytosolische Ribosomen‐Untereinheiten bindet und dadurch die Proteinsynthese im Parasiten hemmt.
