Özet

The in vitro and in vivo effects of some antibiotics on human erythrocyte 6-phosphogluconate dehydrogenase were investigated. Human erythrocyte 6-phosphogluconate dehydrogenase was purified with ammonium sulphate precipitation, 2',5' ADP-Sepharose 4B affinity and gel filtration chromatography. Some antibiotics (netilmicin sulphate, cefepime, amikacin, isepamycin, chloramphenicol, ceftazidim, teicoplanin, ampicillin, ofloxacin, levofloxacin, cefotaxime, penicillin G, gentamicin sulphate, ciprofloxacin) inhibited enzyme activity in vitro but others (cefozin, decefin, streptomycin, combisid, and meronem) were devoid of inhibitory effects. For the drugs having low IC50 values (netilmicin sulphate and cefepime), in vivo studies were performed in rats. Netilmicin sulphate at 15-mg/kg inhibited enzyme activity significantly (p<0.001) 1 h, 2 h, and 3 h after dosing and cefepime at 200-mg/kg very significantly (p<0.001) inhibited the enzyme 1 h and 2 h after dosing. Netilmicin sulphate and cefepime inhibited rat erythrocyte 6-phosphogluconate dehydrogenase both in vivo and in-vitro.
