Title: Novel inhibitors of Rickettsia prowazekii methionine aminopeptidase from the Malaria Box.
Authors: Sharma I, Chen C, Daraji D, Horn JR, Hagen TJ.
Abstract: Methionine aminopeptidases (MetAp) are dinuclear metalloenzymes found in both prokaryotes and eukaryotes that catalyze the hydrolysis of the N-terminal methionine residue from nascent proteins, an important post-translational modification, which makes it an attractive target for drug discovery. Rickettsia prowazekii (Rp) is an obligate pathogen and causative agent of epidemic typhus and typhus fever. In our ongoing search for anti-rickettsial agents we screened 400 compounds from the Malaria Box for inhibition of RpMetAp1 and discovered 12 compounds that inhibited the enzyme with IC50 values ranging from 800 nM to 22 μM. These inhibitors are from eleven different chemical series and represent leads that can be used to discover more potent and efficacious anti-rickettsial agents.
