New antibiotics in infection treatment

The introduction of new molecules with antimicrobial activity is an opportunity for modern antibiotic therapy in the era of rapidly growing resistance to antibiotics. Beta-lactamase-inhibiting antibiotics, cephalosporinases and carbapenemases represent a breakthrough in previous treatments for infections caused by resistant pathogens. Ceftazidime with avibactam and ceftolozane with tazobactam show exceptional efficacy in severe infections. Karbavans is a combination of meropenem and a new boron beta-lactamase inhibitor, as well as the combination of avibactam and aztreonam, are a hope for the treatment of infections caused by Klebsiella pneumoniae resistant to the majority of available antibiotics. S649266 is itself an inhibitor of beta-lactamases. Plazomycin, in turn, is a new aminoglycoside that allows the control of severe bacterial infections caused by multiresistant Enterobacteriaceae, including those resistant to carbapenems. In contrast, omadacyclin, a semi-synthetic derivative of tetracycline, has activity against Gram-positive, Gram-negative, aerobic and anaerobic as well as atypical bacteria. Solithromycin, a new ketolide, has immunomodulatory effects and a broad antiinflammatory spectrum, with no side effects caused by older generations of macrolides. New fluoroquinolones (delafloxacin, zabofloxacin, finefloxacin, nemonoxacin, zoliflodacin) show a wide spectrum of action with less and less side effects. The new MRX-1 preapplate, alongside tedizolid and cadazolid, are further oxazolidinones that show significant activity against multi-resistant Gram-positive pathogens. The presented palette of new molecules with antimicrobial activity will certainly significantly improve the effectiveness of antibiotic therapy.

Key words: beta-lactamases, aminoglycosides, macrolides, ketolides, fluoroquinolones, oxazolidinones
