Pefloxacin is a broad-spectrum and synthetic fluoroquinolone antibiotic and a methylated derivative of norfloxacin (Item No. 25975).{47756,47757} It is active against Gram-negative and Gram-positive bacteria, including clinical isolates of E. coli, K. pneumoniae, S. aureus, and G. vaginalis (MIC90s = 0.12, 0.5, 0.5, and 32 mg/L, respectively).{47756,47757} Pefloxacin selectively inhibits E. coli topoisomerase I and DNA gyrase over calf thymus topoisomerase I (IC50s = 45, 4.5, and >140 μg/ml, respectively) in cell-free assays.{47758} In vivo, pefloxacin is active against systemic E. coli, K. pneumoniae, and P. aeruginosa infections in mice with 50% of efficacy maximum (P50) values of 6.5, 29.2, and 219 mg/kg, respectively.{47759}

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 100 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
