The invention relates to the means for magnetic resonance imaging of oncological diseases and other diseases, accompanied by a locally altered level of absorption of nutrients by cells. The invention is the diagnostic drug containing at least one deuterated derivative of a natural branched-chain amino acid, as well as the diagnostic method based on the use of this diagnostic drug. The method of the invention includes performing magnetic resonance imaging and / or deuterium magnetic resonance spectroscopy after administration of the diagnostic drug in a time sufficient for the accumulation of the diagnostic drug in a target area of a subject's body. The proposed method allows to carry out a highly informative diagnostics of oncological diseases and other diseases, accompanied by a locally altered level of absorption of nutrients by cells.
The main fragmentation processes after electron ionization of butyl methyl and butyl ethyl sulfides are rationalized by the intermediacy of the ion neutral complex [RSH . methylcyclopropane](+.) as demonstrated by extensive labeling and collision activation studies.
