Abstract

Bivalent histamine H2 receptor (H2R) agonists were synthesized by connecting pharmacophoric 3-(2-amino-4-methylthiazol-5-yl)-, 3-(2-aminothiazol-5-yl)-, 3-(imidazol-4-yl)- , or 3-(1, 2, 4-triazol-5-yl) propylguanidine moieties by NG-acylation with alkanedioic acids of various chain lengths. The compounds were investigated for H2R agonism in GTPase and [35S] GTPγS binding assays at guinea pig (gp) and human (h) H2R-GsαS fusion proteins ...
