  A novel series of selective, non-peptide inhibitors of angiotensin II binding to the AT2 site

  摘要：

  The availability of peptide and non-peptide Ang II receptor antagonists has permitted the study of Ang II receptor heterogeneity. It is now widely recognized that there are at least two distinct Ang II receptor subtypes. AT(1) receptors are selective in their recognition of agents such as losartan, DuP 532, L-158,809, SK&F108566, and similar non-peptides. To date, all of the well-known actions of Ang II in mammals are blocked by the AT(1) selective antagonists such as losartan and are thus designated as being mediated by the AT(1) receptor. Although there have been reports of functional activity mediated through AT(2) sites, the pharmacological role for the AT(2) receptor has not yet been elucidated. Herein, we report the chemistry and SAR on a novel series of 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acids which have selective affinity for AT(2) receptors. The most potent of which (19) has an IC50 Of 30 nM for the AT(2) receptor in the rat adrenal radioligand binding assay.
