毒理性
柑橘绿霉素抑制膜结合和可溶性的线粒体ATP酶。尤其是,它抑制突触体Na+/K+-ATP酶,改变突触传递,并与F1-ATP酶的beta亚单位结合。因此,它已被证明可以抑制线粒体能量相关反应,如ADP刺激的呼吸、ATP驱动的琥珀酸还原NAD+和ATP驱动的NAD转移酶。霉菌毒素通常能够通过人类有机阴离子转运体(hOATs)和人类有机阳离子转运体(hOCTs)进入肝脏和肾脏。它们还可以抑制这些转运体的阴离子和阳离子摄取,干扰内源代谢物、药物和外源性物质(包括它们自身)的分泌。这导致细胞内毒性化合物的积累增加,引起肾毒性和肝毒性。(A3002,A3003,A3005,A3006,A3014)
Citreoviridin inhibits both membrane-bound and soluble mitochondrial ATPases. In particular, it inhibits synaptosomal Na+/K+-ATPase, altering synaptic transmission, and binds to the beta subunit of F1-ATPAse. As a result it has been shown to inhibit mitochondrial energy-linked reactions such as ADP-stimulated respiration, ATP-driven reduction of NAD + by succinate, and ATP-driven NAD transhydrogenase. Mycotoxins are often able to enter the liver and kidney by human organic anion transporters (hOATs) and human organic cation transporters (hOCTs). They can also inhibit uptake of anions and cations by these transporters, interfering with the secretion of endogenous metabolites, drugs, and xenobiotics including themselves. This results in increased cellular accumulation of toxic compounds causing nephro- and hepatotoxicity. (A3002, A3003, A3005, A3006, A3014)
