Synthesis and activity of conformationally-constrained macrocyclic norstatine-based inhibitors of HIV protease
1996
Abstract Two diastereomers of a macrocyclic hydroxyamide (norstatine-based) peptide, having an 18-membered ring system, have been synthesized as HIV protease inhibitors. The ( R )-diastereomer (IC 50 19 nM) was ∼17-fold weaker than an acyclic analog, but had comparable or better antiviral activity, suggesting improved cell penetration properties and/or resistance to cellular enzymes for the macrocyclic inhibitor.
