Determination of Isepamicin sulfate and related compounds by high performance liquid chromatography using evaporative light scattering detection
J Pharm Biomed Anal 2001 Jan;24(3):405-12.PMID:11199219DOI:10.1016/s0731-7085(00)00465-9.
A simple reversed phase high performance liquid chromatographic method was developed for the analysis of Isepamicin sulfate. The use of evaporative light scattering detection eliminates the need for sample derivatization. Separation of the isepamicin aminoglycoside from structurally similar related compounds was achieved using two Waters X-Terra RP18 columns connected in tandem at 10 degrees C. The assay of Isepamicin sulfate and the estimation of its impurities was accomplished using external standard calibration curves at two sample concentrations: 1.6 mg ml(-1) for the analysis of Isepamicin sulfate and 8.0 mg ml(-1) for the estimation of lower level impurities. The limit of detection was 0.1%. The specificity, assay linearity, low level assay linearity and assay repeatability were also investigated.
Isepamicin sulfate-induced sensorineural hearing loss in patients with the 1555 A-->G mitochondrial mutation
ORL J Otorhinolaryngol Relat Spec 1998 May-Jun;60(3):164-9.PMID:9579362DOI:10.1159/000027590.
A mitochondrial mutation at nucleotide 1555 has been reported to be susceptible to aminoglycoside antibiotics as well as one of the causes of nonsyndromic sensorineural hearing loss. We herewith report 2 cases bearing the 1555 A-->G mitochondrial mutation who had hearing loss after short-term exposure to the new aminoglycoside antibiotic, Isepamicin sulfate. Even when using aminoglycoside antibiotics with milder side effects, careful attention should be paid in applying them to patients with particular genetic backgrounds.
Effects of some antibiotics on activity of glucose-6-phosphate dehydrogenase from human erythrocytes in vitro and effect of Isepamicin sulfate on activities of antioxidant enzymes in rat erythrocytes
Drug Chem Toxicol 2005;28(4):433-45.PMID:16298874DOI:10.1080/01480540500262854.
The purpose of this study was to investigate effects of some antibiotics on glucose-6-phosphate dehydrogenase (G6PD), antioxidant enzymes, and malondialdehyde (MDA). Initially, for in vitro studies, G6PD was purified from human erythrocyte, 9811-fold in a yield of 42.4% by using ammonium sulfate precipitation and 2',5' ADP-Sepharose 4B affinity gel. The purified enzyme showed a single band on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The effects of four different antibiotics (Isepamicin sulfate, meropenem, chloramphenicol, and thiamphenicol glisinat hydrochloride) were investigated on the purified enzyme. K(i) value and type of inhibition were determined by means of Lineweaver-Burk graphs and regression analysis graphs. Isepamicin sulfate inhibited the enzyme activity (I(50) value, 2.1 mM; K(i) value, 1.7 mM), whereas thiamphenicol glisinat hydrochloride activated the G6PD dose dependently. Other drugs showed no inhibition and activation effect. In addition, the effects of Isepamicin sulfate on the activities of G6PD, glutathione reductase (GR), superoxide dismutases (SOD), glutathione peroxidase (GPx), catalase (CAT), and glutathione S-transferase (GST) and MDA concentrations were examined in Sprague-Dawley rat erythrocytes in vivo. A marked alteration in the activities of these enzymes and MDA levels may be the result of oxidative stress in the rats receiving Isepamicin sulfate.
