Recent advances in pharmaceutical chemistry--review II. Histamine H2-receptor antagonists
Abstract:
The concept of histamine receptors is outlined and the rationale for the synthesis of H2-antagonists presented. Structure-activity relationships among these compounds are described and aspects of absorption, distribution and elimination discussed with particular reference to cimetidine and ranitidine. Oxmetidine, lupitidine and loxtidine are also considered. Methods for the analysis of these drugs in body fluids are presented followed by a discussion of their toxicology. Volunteer and patient studies are also surveyed.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
