Graphical Abstract

Komplex(e) Probleme: Die Kristallstruktur der Mitogen-aktivierten Proteinkinase p38α im Komplex mit einem Dibenzo[a,d]cycloheptenon-Inhibitor erwies sich als unvereinbar mit NMR-spektroskopischen Daten für denselben Komplex in Lösung. Durch inferenzielle Strukturaufklärung (ISD) unter Verwendung von Randbedingungen aus Röntgenkristallographie und NMR-Spektren wurde eine Struktur ermittelt, die mit beiden Datensätzen kompatibel und der Röntgenkristallstruktur sehr ähnlich ist (siehe Bild).
