  Allosteric Modulators of the Adenosine A₁ Receptor: Synthesis and Pharmacological Evaluation of 4-Substituted 2-Amino-3-benzoylthiophenes

  摘要：

  A series of 4-substituted 2-amino-3-benzoylthiophenes was screened using a functional assay of A A(1)AR-mediated phosphorylation of ERK 1/2 in intact CHO cells to identify both potential agonistic effects as well the ability to allosterically modulate the activity of the orthosteric agonist, R-PIA. More detailed concentration-response experiments were subsequently performed on two compounds (9a and 9o) utilizing both the ERK 1/2 assay as well as a second assay of [S-35]GTP gamma S binding to activated G proteins.

  A direct and efficient approach to 1,3,5-trisubstituted benzenes has been developed via N-heterocyclic carbene-catalyzed [2 + 4] annulation of α-bromoenals and α-cyano-β-methylenones. The reaction worked well for both aryl- and alkylenones.

  A DBU-mediated synthesis of 1,3,5-trisubstituted benzenes was developed via the [2 + 4] annulation of in situ activated α,β-unsaturated carboxylic acids and α-cyano-β-methylenones. The dual role of DBU as Brønsted base and nucleophilic Lewis base is the key for the success of the reaction.

  通过原位活化的α，β-不饱和羧酸和α-氰基-β-甲基烯酮的[2 + 4]环空反应，开发了DBU介导的1,3,5-三取代苯的合成方法。DBU作为Brønsted碱和亲核Lewis碱的双重作用是反应成功的关键。
