Biochemical and Pharmacological Roles of Adenosylmethionine and the Central Nervous System contains the proceedings of an International Round Table on Adenosylmethionine and the Central Nervous System held in Naples, Italy, on May 2, 1978. The papers explore the biochemical and pharmacological roles of S-adenosylmethionine (SAM), with particular emphasis on its functions in the central nervous system (CNS). This book consists of 13 chapters and opens with an introduction to some novel biochemical aspects of SAM and related sulfur compounds, paying particular attention to transmethylation reactions; polyamine biosynthesis and unusual biological roles of adenosylmethionine; metabolic pathways related to adenosine-sulfur compounds; and transport of adenosylmethionine. The following chapters discuss a number of chemical and biochemical properties of SAM as well as its pharmacological aspects within the CNS. The relation between folate and adenosylmethionine metabolism in the brain is examined, along with the effect of SAM administration on noradrenaline and serotonin metabolism in rat brain; cerebral utilization of adenosylmethionine and adenosylhomocysteine; and antidepressant effects of adenosylmethionine. Methylation in schizophrenia is also considered. This monograph will be a valuable source of information for biochemists and pharmacologists.
