毒理性
识别和使用:冰片酸(BA)是一种白色无定形固体。已知BA是由细菌Burkholderia gladioli pv. cocovenenans产生的。它被用作生物化学研究的工具。人体研究:在莫桑比克的一个农村小镇,超过230人因饮用pombe(一种传统酒精饮料)而生病,其中75人死亡。在可疑的pombe中检测到BA的有毒水平,但在对照的pombe中没有。产生BA的细菌Burkholderia gladioli pathovar cocovenenans在制作pombe的面粉中被检测到。BA是腺苷酸转位酶(ANT)的抑制剂。由于抑制ANT与抑制线粒体中细胞色素c的释放有关,这进而导致凋亡的抑制,因此它被用作研究凋亡机制的工工具。BA与印度尼西亚和中国的椰子和玉米制品食源性疾病爆发有关。动物研究:BA是线粒体ATP/ADP转位酶的强效抑制剂,通过刺激ATP敏感的钾通道(K-ATP通道)活性,抑制胰腺β细胞中由葡萄糖诱导的电活动。
IDENTIFICATION AND USE: Bongkrekic acid (BA) is a white amorphous solid. BA is known to be produced by the bacterium Burkholderia gladioli pv. cocovenenans. It is used as a tool in biochemical research. HUMAN STUDIES: In a rural town in Mozambique, >230 persons became sick and 75 died of an illness linked to drinking pombe, a traditional alcoholic beverage. Toxic levels of BA were detected in the suspect pombe but not the control pombe. Burkholderia gladioli pathovar cocovenenans, the bacteria that produces BA, was detected in the flour used to make the pombe. BA is an inhibitor of adenine nucleotide translocase (ANT). Since inhibition of ANT is connected to the inhibition of cytochrome c release from mitochondria, which then results in the suppression of apoptosis, it has been used as a tool for the mechanistic investigation of apoptosis. BA has been implicated in outbreaks of food-borne illness involving coconut- and corn-based products in Indonesia and China. ANIMAL STUDIES: BA, 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.
