代谢
代谢研究证实了5-壬酮在体内转化为2,5-壬二酮、甲基正丁基酮和2,5-己二酮,其中2,5-己二酮是正己烷和甲基正丁基酮中最活跃的神经毒性代谢物。正己烷、甲基正丁基酮和5-壬酮的神经毒性通过它们的代谢物——一个γ-二酮,2,5-己二酮——而相互联系。
Metabolic studies confirmed the in vivo conversion of 5-nonanone to 2,5-nonanedione, methyl-n-butyl ketone, and 2,5-hexanedione, the latter of which is the most active neurotoxic metabolite of n-hexane and methyl-n-butyl ketone. The neurotoxicities of n-hexane, methyl-n-butyl ketone, and 5-nonanone are linked by virtue of their metabolism to a gamma -diketone, 2,5-hexanedione.
