Introducing purine bases to P2-ligands might enhance the potency of Human Immunodeficiency Virus-1 (HIV-1) protease inhibitory because of the carbonyl and NH groups promoting the formation of extensive H-bonding interactions. In this work, thirty-three compounds are synthesized and evaluated, among which inhibitors 16a, 16f and 16j containing N-2-(6-substituted-9H-purin-9-yl)acetamide as the P2-ligands along

Disclosed are compounds of formula (I), and pharmaceutically acceptable salts thereof, which are inhibitors of the complement system. Also provided are pharmaceutical compositions comprising such a compound, and methods of using the compounds and compositions in the treatment or prevention of a disease or condition characterized by aberrant complement system activity.
Disclosed is a peptide nucleic acid monomer as well as a corresponding peptide nucleic acid molecule. The monomer comprises a terminal amino group and a terminal group A. The terminal amino group and the terminal group A are connected by an aliphatic moiety. The main chain of this aliphatic moiety is free of groups that are charged under physiological conditions. The terminal group A is one of —COOH, —COOR
