  Pyrazolo[1′,5′:1,6]pyrimido[4,5-d]pyridazin-4(3H)-ones as selective human A1 adenosine receptor ligands

  摘要：

  A series of pyrazolo[1',5':1,6]pyrimido[4,5-d]pyridazin-4(3H)-ones was synthesized and tested in radio-ligand binding assays to determine their affinities for the human adenosine A(1), A(2A), A(2B) and A(3) receptors. Results indicated that this scaffold is appropriate for adenosine receptor subtype A1 ligands and that the best arranged groups around this scaffold are 3- and 4-pyridinyl at position 1, benzyl at position 3, hydrogen at position 6 and 3- thienyl or phenyl at position 9. The most interesting compounds showed K-i for A1 in the nanomolar range and an appreciable selectivity for other receptor subtypes. (C) 2010 Elsevier Ltd. All rights reserved.
