Abstract

original image

Inhibitoren der Wechselwirkung zwischen dem Protein VLA-4 und seinem natürlichen Liganden VCAM-1 wurden entwickelt, obwohl die Struktur des Proteins unbekannt ist. Das rationale Design basierte auf der Simulation der sterischen und elektronischen Eigenschaften der aktiven Schleife von VCAM-1, dessen Struktur bekannt ist (siehe Bild), und die Inhibitoren waren einfach durch stereoselektive schrittweise [3+2]-Cycloadditionen zugänglich.
