In a recent paper (Colotta et al. J. Med. Chem. 2000, 43, 1158-1164) we reported the synthesis and adenosine receptor binding activity of two sets of 2-aryl-1,2,4-triazolo[4,3-a]quinoxalines (A and B) some of which were potent and selective A(1) or A(3) antagonists. In this paper the synthesis of a set of 2-arylpyrazolo[3,4-c]quinolin-4-ones 1-10, 4-amines 11-18, and 4-amino-substituted derivatives
在最近的一篇论文中(Colotta等人,J。Med。Chem。2000,43,1158-1164),我们报道了两组2-芳基-1,2,4-三唑并[4,3,3,4,3,3,4,3,3,4,3,3,3,3,3,3,3,4,3,4,3,3,4,3]的合成和腺苷受体结合活性。 3-a]喹喔啉(A和B),其中一些是有效的和选择性的A(1)或A(3)拮抗剂。在本文中,报道了一组2-芳基吡唑并[3,4-c]喹啉-4-酮1-10、4-胺11-18和4-氨基取代的衍生物19-35的合成。在牛A(1)和A(2A)以及人类克隆的A(3)腺苷受体上的结合活性表明(i)附加的2-苯环上的取代基可用于调节A(1)和A(3) )亲和力;(ii)4-氨基对于A(1)和A(2A)的结合活性必不可少,并且(iii)4位的核或核外C = O质子受体产生有效且有选择性的A(3)拮抗剂。这些结果与先前报道的系列A和B的结果一致,表明
