摘要:
Recent research on histamine H-2 receptor agonists was focused on quantitative structure-activity relationships and receptor models explaining the activity of imidazolylpropylguanidines. Their selectivity for guinea pig vs. human isoforms was investigated using H-2 receptor-G(salpha) fusion proteins and attributed to amino acid differences in transmembrane domains 1 and 7. New antagonists result from approaches to improve pharmacokinetic properties and to design hybrid drugs which additionally have gastroprotective or anti H. pylori activity.
