with hydrazine hydrate which were obtained by a known one-pot synthesis. The affinities of these compounds for adenosine A(1)/A(2A) receptors were determined at 1 microM concentration. The test compounds which exhibited more than 20% inhibition were selected and further screened at six different concentration levels to estimate their EC(50)/K(i) values. The most potent compounds in the series were 4c and
新系列的5-烷基/芳基-8,9-二甲基/ 8,9,10,11-四氢[1]苯并噻吩并[3,2-e] [1,2,4]三唑o [4,3- c]嘧啶-3(2H)-硫酮(4a-k)是通过4-肼基-2-烷基/芳基-5,6-二甲基/ 5,6,7,8-四氢[ 1] benzothieno [2,3-d] pyri Midines(3a-k)在碱性条件下使用二硫化碳。通过取代氯,制备4-肼基-2-烷基/芳基-5,6-二甲基/ 5,6,7,8-四氢[1]苯并噻吩并[2,3-d]吡啶亚氨酸(3a-k)用水合肼制得4-氯-2-取代的5,6-二甲基/ 5,6,7,8-四氢[1]苯并噻吩并[2,3-d]嘧啶二烯(2a-k)已知的一锅合成。这些化合物对腺苷A(1)/ A(2A)受体的亲和力是在1 microM浓度下测定的。选择表现出超过20%抑制作用的测试化合物,并在六个不同浓度水平下进一步筛选以估计其EC(50)/
