2-Amino-3-benzoylthiophenes (2A3BTs) have been widely reported to act as allosteric enhancers (AEs) at the A(1) adenosine receptor (A(1)AR). Herein we describe the synthesis of a series of 1-aminoindeno[1,2-c]thiophen-8-ones and a series of (2-aminoindeno[2,1-b]thiophen-3-yl)(phenyl)methanones as conformationally rigid analogues of the 2A3BTs. These compounds were screened using a functional assay of A(1)AR-mediated phosphorylation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) in intact Chinese hamster ovary (CHO) cells to identify both potential agonistic effects as well as the ability to allosterically modulate the activity of the orthosteric agonist, N(6)-(R-phenylisopropyl)a..View full abstract
