Doxycycline

Overview

Basic Info

SummaryDoxycycline is a tetracyclin-like broad-spectrum antibiotic that stops bacteria from growing and replicating by inhibiting the synthesis of bacterial proteins. Doxycycline mechanisms by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the ribosome A site. This hinders the production of proteins and ultimately leads to the death of bacterial cells. Doxycycline is widely used to treat respiratory infections, urinary tract infections and sexually transmitted infections caused by bacteria. Its effectiveness, versatility and low cost make it a valuable tool in the fight against infectious diseases.
