  Allosteric Modulation of the Adenosine A₁ Receptor. Synthesis and Biological Evaluation of Novel 2-Amino-3-benzoylthiophenes as Allosteric Enhancers of Agonist Binding

  摘要：

  Novel allosteric enhancers of agonist binding to the rat adenosine Al receptor are described. The lead compound for the new series was PD 81,723 ((2-amino-4,5-dimethyl-3-thienyl)[3(trifluoromethyl)phenyl]methanone), a compound previously reported by Bruns and co-workers (Mol. Pharmacol. 1990, 38, 950-958). The 4,5-dimethyl group and the benzoyl moiety were targets for further modifications, leading to series of 4,5-dialkyl (12a-g), of tetrahydrobenzo (12h-u), and of tetrahydropyridine (13a-g) derivatives. A number of compounds, in particular 12b, 12e, 12j, 12n, and 12u, proved superior to PD 81,723, Their EC50 values for enhancing the binding of the adenosine Al receptor agonist N-6-cyclopentyladenosine to the receptor were lower, and/or their antagonistic activity on the adenosine Al receptor was shown to be diminished.

  2-Amino-3-benzoylthiophenes are allosteric enhancers (AE) of agonist activity at the A(1) adenosine receptor. The present report describes syntheses and assays of the AE activity at the human A(1)AR (hA(1)AR) of a panel of compounds consisting of nine 2-amino-3-aroylthiophenes (3a-i), eight 2-amino-3-benzoyl-4,5-dimethylthiophenes (12a-h), three 3-aroyl-2-carboxy-4,5-dimethylthiophenes (15a-c), 10 2-amino-3-benzoyl-5,6-dihydro-4H-cyclopenta[b]thiophenes (17a-j), 14 2-amino-3-benzoyl-4,5,6,7-tetrahydrobenzo[b]thiophenes (18a-n), and 15 2-amino-3-benzoyl-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophenes (19a-o). An in vitro assay employing the A(1)AR agonist [I-125]ABA and membranes from CHO-K1 cells stably expressing the hA(1)AR measured, as an index of AE activity, the ability of a candidate AE to stabilize the agonist-A(1)AR-G protein ternary complex. Compounds 3a-i had little or no AE activity, and compounds 12a-h had only modest activity, evidence that AE activity depended absolutely on the presence of at least a methyl group at C-4 and C-5. Compounds 17a-c lacked AE activity, suggesting the 2-amino group is essential. Polymethylene bridges linked thiophene C-4 and C-5 of compounds 17a-j, 18a-n, and 19a-o. AE activity increased with the size of the -(CH2)(n)- bridge, n = 3 < n = 4 < n = 5. The 3-carbethoxy substituents of 17a, 18a, and 19a did not support AE activity, but a 3-aroyl group did. Bulky (or hydrophobic) substituents at the meta and para positions of the 3-benzoyl group and also 3-naphthoyl groups greatly enhanced activity. Thus, the hA(1)AR contains an allosteric binding site able to accommodate 3-aroyl substituents that are bulky and/or hydrophobic but not necessarily planar. A second region in the allosteric binding site interacts constructively with alkyl substituents at thiophene C-4 and/or C-5.
