| Outline of Final Research Achievements |
It is essentially pre-requisite for the prompt diagnosis and the treatment of diseases caused by congenital adrenocortical hyper-/hypoplasia originated from the chromosomal abnormality, because those disease are usually intractable. In this research, our purpose was directed for the development of the microdetermination of cortisol and its related precursors/metabolites in small amount of biological samples based on the use of proton-affinitive derivatization and LC-ESI-MS/MS. In addition, we investigated the syntheses of deuterated internal standards, 18-oxocortisol as an authentic sample and the preparation method of various kinds of proton-affinitive derivatives, and their utilities in LC-ESI-MS/MS. Of these derivatives, we revealed that the picolinate ester was the most useful, and the application of the present derivative for the diagnosis of diseases of the abnormality of adrenocortical hormone production was carried out.
