Metabolite Identification
Common Name11a-hydroxytigecycline
Description11a-hydroxytigecycline is a member of the tetracycline class of antibiotics, specifically a metabolite of tigecycline. Chemically, it is characterized by the presence of a hydroxyl group at the 11a position, which alters its interaction with biological targets. This modification affects its ability to inhibit protein translation, as evidenced by the fact that 11a-hydroxytigecycline has a weakened ability to form a complex with the ribosome compared to its parent compound, tigecycline (PMID:16128584 ). Additionally, 11a-hydroxytigecycline forms a weaker complex with magnesium, an essential cofactor for binding tetracycline to the ribosome, which is critical for its antibacterial activity (PMID:16128584 ). The enzymatic modification of tigecycline to 11a-hydroxytigecycline by TetX contributes to antibiotic resistance, highlighting the importance of chemical structure in determining the efficacy of antibiotic agents and their interactions in biological pathways related to protein synthesis.
