  • Extracellular adenosine can exert its function through activation of adenosine receptors (A1, A4a, A1b, A2) or can be transported into the cells viagra duration of erection by the nucleoside transporter. It is mainly formed by the novo purine synthesis, phosphohydrolysis of adenine nucleotides or by hydrolysis of S-adenosyl homocysteine. Paracrine and endocrine actions, adenosine is a purine nucleoside present Role of the Energy State of Liver Cell in Cirrhosis Development and Treatment 47 within and outside cells that acts as chemical messenger with autocrine.

    Within the cell, adenosine is phosphorylated by adenosine kinase, is deaminated to inosine by adenosine deaminase or is converted to S-adenosyl-homocysteine by S-adenosyl-homocysteine hydrolase [113]. Its metabolism is very active resulting viagra duration of erection in a short half live of the nucleoside. The physiological actions of adenosine are multiple, in the central nervous tissue [184] the cardiovascular system [135], modulating the immune response [186] and as a metabolic modulator [173].

    Among the last actions is the contribution of the maintenance of energetic homeostasis in the liver, blood and brain [194]. In order to find a possible mechanism of action, several derivatives of adenosine were tested.
