Bongkrekic acid causes fatal food poisoning which is associated with hyperglycaemia. Here we demonstrate that bongkrekic acid, a potent inhibitor of the mitochondrial ATP/ADP translocase, inhibits glucose-induced electrical activity in the pancreatic beta-cell through the stimulation of ATP-sensitive potassium channel (K-ATP-channel) activity. By comparison of its effects with those of oligomycin, we suggest that bongkrekic acid acts by the inhibition of glucose metabolism and may induce hyperglycaemia by impairing beta-cell function.
邦克酸会导致与高血糖相关的致命食物中毒。在此我们证明,作为线粒体ATP/ADP转位酶的强效抑制剂,邦克酸通过刺激ATP敏感性钾通道(K-ATP通道)活性来抑制胰腺β细胞中葡萄糖诱导的电活动。通过将其作用与寡霉素的作用进行比较,我们认为邦克酸通过抑制葡萄糖代谢起作用,并且可能通过损害β细胞功能诱导高血糖。
