  Synthesis and Antibacterial Activity of Ketolides (6-O-Methyl-3-oxoerythromycin Derivatives):  A New Class of Antibacterials Highly Potent Against Macrolide-Resistant and -Susceptible Respiratory Pathogens

  摘要：

  In the search for new antibiotics active against macrolide-resistant pneumococci and Haemophilus influenzae, we synthesized a new class of 3-oxo-6-O-methylerythromycin derivatives, so-called "ketolides". A keto function was introduced in position 3 after removal of L-cladinose, a sugar which has long been thought essential. Further modifications of the macrolactone backbone allowed us to obtain three different series of 9-oxime, 11,12-carbamate, and 11,12-hydrazonocarbamate ketolides. These compounds were found to be very active against penicillin/erythromycin-resistant pneumococci and noninducers of MLS(B) resistance. The 11,12-substituted ketolide 61 (HMR 3004) demonstrated a potent activity against multiresistant pneumococci associated with a well-balanced activity against all bacteria involved in respiratory infections including H. influenzae, Mycoplasma catarrhalis, group A streptococci, and atypical bacteria. In addition HMR 3004 displayed high therapeutic activity in animals infected by all major strains, irrespective of their resistance phenotype.

  A series of 9-oxime-11,12-carbamate ketolides was synthesized for the first time through a key 11,12-hydrazonocarbamate intermediate that was first oximated and further deaminated to give the corresponding carbamate. The N-N bond cleavage was achieved through an original new reaction using glycoaldehyde dimer as deaminating reagent. The new compounds synthesized were shown to display improved antibacterial activities against Streptococcus pneumoniae and S. pyogenes resistant to erythromycin. (C) 2003 Elsevier Science Ltd.
