  • Publication number: 20050026873
    Abstract: Novel compounds act as molecular inhibitors to target new enzymatic targets on bacteria and provide a new class of bactericidal compounds. The compounds provide for selective inhibition of Type I methionyl aminopeptidases (MetAPs) in bacteria. Because humans and other animals have both type-I and type-II MetAPs, which are functionally equivalent, the compounds are bactericidal but do not completely inhibit MetAP activity in humans and other animals. The compounds also have anti-microbial activity in microbes other than bacteria provided the targeted microbes have predominately type-I MetAP.
