N6-substituted 1-deazaadenosines largely retain the A1 agonist activity of their parent compounds, but lose some of their A2 agonist activity. This results in A1-selective compounds, of which N6-cyclopentyl-2-chloro-1-deazaadenosine (1-deaza-2-Cl-CPA, 2b) was identified as the most selective agonist at A1 adenosine receptors so far known. The activity of all 1-deaza analogues confirms that the presence
为了寻找更具选择性的A1腺苷受体激动剂,N6-[(R)-(-)-1-甲基-2-苯乙基] -1-脱氮杂腺苷(1-deaza-R-PIA,3a),N6-环戊基-从5,7-二氯-3-β-D合成了1-deazaadenosine(1-deazaCPA,3b),N6-cyclohexyl-1-deazaadenosine(1-deazaCHA,3c)和相应的2-氯衍生物2a-c。 -核呋喃糖基-3H-咪唑并[4,5-b]吡啶。另一方面,制备了N-乙基-1′-脱氧-1′-(1-deaza-6-氨基-9H-嘌呤-9-基)-β-D-呋喃呋喃核糖酰胺(1-deazaNECA,10)。为了寻找更具选择性的A2激动剂,从7-硝基-3-β-D-呋喃呋喃糖基-3H-咪唑并[4,5-b]吡啶中合成了吡咯烷酮。在腺苷酸环化酶和放射性配体结合研究中已经确定了所有deaza类似物对腺苷受体的活性。1-DeazaNECA被证
