Common Namestreptothricin D
DescriptionStreptothricin D is a member of the aminoglycoside antibiotic class, characterized by its unique chemical structure that includes three lysine residues. This compound is notable for its role in antimicrobial activity, particularly against highly drug-resistant pathogens such as carbapenem-resistant Enterobacterales (CRE) and Acinetobacter baumannii, as evidenced by studies demonstrating its efficacy in purifying and characterizing its components (PMID:37192172 ). The chemical analysis techniques, including RP-HPLC and ESI-MS/MS, have identified streptothricin D among other antimicrobial compounds produced by various strains, highlighting its significance in the context of antibiotic resistance (PMID:34603354 ). Additionally, spectroscopic methods like FTIR and LCMS have confirmed the structural similarities of streptothricin D to other antibiotic variants, further elucidating its chemical properties with a mass-to-charge ratio (m/z) of 758.42 (PMID:33950512 ). Streptothricin D's involvement in biosynthetic pathways contributes to its potential applications in combating resistant bacterial infections, underscoring the importance of understanding its chemistry and biological interactions.
