Dissociation of antimicrobial and hemolytic activities of gramicidin S through N-methylation modification.

abstract：:An emerging and attractive target for the treatment of Alzheimer's disease is to inhibit the aggregation of beta-amyloid protein (Abeta). We applied the retro-enantio concept to design an N-methylated peptidic inhibitor of the Abeta42 aggregation process. This inhibitor, inrD, as well as the corresponding all-L (inL) ...
