Description

Gentamicin X2 sulfate is one of several different components found in standard grade gentamicin. Gentamicin A, gentamicin B, gentamicin X2, and others are considered “minor components,” have little antimicrobial properties, and account for approximately 20% of standard grade gentamicin. The major components of gentamicin are members of the gentamicin C complex which account for up to 80% of standard grade gentamicin and possess higher antimicrobial properties. The minor gentamicin components (A, B, X2, etc) contain hydroxy groups in the 3’ and 4’ positions of the purpurosamine (2-amino-hexose) ring. The gentamicin C complex does not have hydroxy groups at these locations. This structural difference is thought to account for the difference in antimicrobial activity between the minor (gentamicins A, B, X2, etc..) and the gentamicin C complex. Gentamicin X2 sulfate, EvoPure® is ≥98.0% gentamicin X2.

Huang et al. used gentamicin A sulfate, EvoPure® and gentamicin X2 sulfate, EvoPure® to study enzymatic conversion of gentamicin A2 to other gentamicin congeners. "Delineating the Biosynthesis of Gentamicin X2, the Common Precursor of the Gentamicin C Antibiotic Complex."
