Looking for new preparations for antibacterial therapy. IV. New antimicrobial agents from the aminoglycoside, macrolide and tetracycline groups in clinical trials.

This paper is the fourth in a series on the search for new antibacterial therapies, and covers new compounds belonging to the aminoglycoside, macrolide and tetracycline groups of antibiotics. The article describes eight new substances at the clinical trial stage of development. One of them is an aminoglycoside (plazomicin), four are macrolides, collectively known as ketolides (cethromycin, solithromycin, EDP-420 and EDP-788), and the remaining three are members of the tetracycline group (omadacycline, eravacycline, sarecycline). Despite the long-term and very expensive process of collecting documentation proving the efficacy of antimicrobial drugs, there is a possibility, that particular compounds find use as active ingredients of medicinal products allowing for the triumph over the clinically relevant, dangerous bacteria.
