Nitrofurantoin 57-71 hemoglobin subunit gamma 2 Homo sapiens 40-53 6273444-1 1982 Nitrofurantoin was found to interact with HbO2 to cause the concomitant formation of methemoglobin and superoxide. Nitrofurantoin 0-14 hemoglobin subunit gamma 2 Homo sapiens 85-98 6273444-2 1982 The rate of formation of methemoglobin and superoxide was linearly dependent upon the concentration of nitrofurantoin and could be inhibited by superoxide dismutase, catalase, or the prior conversion of HbO2 to ethylioscyanoferrohemoglobin. Nitrofurantoin 103-117 hemoglobin subunit gamma 2 Homo sapiens 25-38
