Synthesis, X-ray Crystallography, and Pharmacokinetics of Novel Azomethine Prodrugs of (R)-.alpha.-Methylhistamine: Highly Potent and Selective Histamine H3 Receptor Agonists
Since various neuroregulatory functions of the histamineH3receptor have been proved during the last few years, the H3receptor is of current interest. Azomethine derivatives of the highly potenthistamineH3receptoragonist (R)-alpha-methylhistamine (1) were prepared as lipophilic prodrugs to improve the bioavailability of the hydrophilic drug, particularly its entry into the brain. Additionally
