cycloalkylthiophenes, tetrahydrobenzo[b]thiophene derivatives appeared to be more potent than the dihydrocyclopentadien[b]thiophene counterparts. Some of the most potent compounds were tested at a concentration of 10 microM for their affinity as competitors to the antagonist binding site of CHO cells expressing hA(1), hA(2A), and hA(3) adenosine receptors. None inhibited binding at the hA(2A)AR, but most
当前的研究描述了一系列新型的2-氨基-3-萘噻吩并在噻吩的4-位和5-位以及萘环上有可变的修饰。以多种方式测量了变构增强子的活性:(1)在表达克隆的人A(C)的中国仓鼠卵巢(CHO)细胞中,在A(1)-腺苷激动剂(CPA)存在的情况下评估对福司柯林刺激的cAMP积累的影响。 1)-腺苷受体(hA(1)AR); (2)这些化合物取代[(3)H] DPCPX,[(3)H] ZM 241385和[(3)H] MRE 3008F20与表达hA( 1),hA(2A)和hA(3)腺苷受体;(3)对[(3)H] CCPA与表达hA(1)AR的CHO细胞膜结合的影响,含有天然腺苷A(1)受体的大鼠大脑和人类皮质膜制剂;(4)[(3)H] CCPA从CHO-hA1膜解离的动力学。药理分析比较了各种活性与参考化合物PD 81,723(化合物1)的活性。在CHO:hA(1)分析中,几种化合物似乎比PD 81,7
