Abstract

Substitution an der äußeren Oberfläche des Sechs-Helix-Peptidbündels verbesserte die Löslichkeit und erhöhte die Anti-HIV-1-Aktivität von SC-Peptiden. Die Reste E und K an den Positionen b, c, f und g (siehe Schema) stabilisieren die für die Inhibierung essenzielle α-Helixkonformation; die Reste Z an den Positionen a, d und e wechselwirken mit dem inneren Strang.
