酸化ストレス
Divicine reacts with oxygen in red blood cells, which creates reactive oxygen species such as hydrogen peroxide and superoxide anion. These molecules are strong oxidizers of NADPH and glutathione. G6PD deficient individuals cannot regenerate NADPH quickly enough to prevent depletion of glutathione. This depletion results in the cells having no protection against oxidative stress caused by the aglycones. Oxidative stress leads to damage of haemoglobin and disulphide bond aggregates (Heinz bodies), which result in haemolytic anaemia, called favism.
