Guanidinylated 2,5-dideoxystreptamine derivatives as anthrax lethal factor inhibitors.
Anthrax lethal factor is a Zn(2+)-dependent metalloprotease and the key virulence factor of tripartite anthrax toxin secreted by Bacillus anthracis, the causative agent of anthrax. A series of guanidinylated 2,5-dideoxystreptamine derivatives were designed and synthesized as inhibitors of lethal factor, some of which show strong inhibitory activity against lethal factor in an in vitro FRET assay. Preparation and structure-activity relationships of these compounds are presented.
