    Biological Activity

    PTC-672 (PTC672) is a novel orally active inhibitor that exhibits a narrow spectrum of activity against Neisseria gonorrhoeae (N. gonorrhoeae, Ng) including MDR isolates (MIC, 0.05 to 0.4 ug/mL), directly inhibits class Ia ribonucleotide reductase (RNR).
    PTC-672 is inactive against the panel of Gram-negative pathogens and normal gut organism (MICs ranging from 12.5 to ≥62.5 ug/mL).
    PTC-672 demonstrates clear antibiotic activity preference toward all Neisseria species examined including MDR organisms and the Nm M2092 serogroup B (NMSB) reference strain.
    PTC-672 targets DNA synthesis and the class Ia RNR large subunit, but not DNA topoisomerases. PTC-672 showed 78% inhibition at 2.5 μM aginst Ng RNR activity, also inhibits Ec RNR, but does not inhibits human RNR at 100 uM.
    PTC-672 (30 mg/kg) demosntrates in vivo efficacy in a mouse model of gonorrhea.
