  8-环烷基-1,3-二丙基黄嘌呤作为腺苷受体拮抗剂的构效关系。

  摘要：

  8-取代的黄嘌呤目前代表最有效的腺苷-受体拮抗剂。制备了一系列8-取代的1，3-二丙基黄嘌呤，并确定了它们分别作为人血小板和大鼠脂肪细胞的A1和A2腺苷受体拮抗剂的效力。没有研究药物能像A1腺苷受体拮抗剂那样与8-环戊基-1,3-二丙基黄嘌呤一样有效，但是8-（2-甲基环丙基）-1,3-二丙基黄嘌呤比A1腺苷受体的效力至少强1000倍。 A1比A2的腺苷受体高。虽然8-环烷基部分上的大多数取代都导致抑制A1和A2腺苷受体，8- [反式-4-（乙酰氨基甲基）环己基] -1的效力降低，

  A series of 1,3-dipropylxanthines were prepared with a variety of substituents at the 8-position. These included 8-aryl and 8-cycloalkyl groups. Polar carboxylate and carboxamide moieties were introduced as aryl substituents to increase water solubility. 1,3-Dipropyl-8-[2-hydroxy-4-[(carboxymethyl)oxy]phenyl]xanthine provided a functionalized congener with high potency (Ki = 37 nM) and selectivity (54-fold) for A1-adenosine receptors. This congener was used for preparation of a series of other analogues, some with higher potency and some with higher selectivity. 8-Cyclopentyl- and 8-cyclohexyl-1,3-dipropylxanthines were both very potent (Ki = 1-1.5 nM) and selective for A1 receptors, while 8-cycloalkylmethyl analogues were 10-fold less potent, but still very selective for A1 receptors. 8-Piperidinyl and 8-pyrazinyl analogues had very low activities as adenosine receptor antagonists.

  least 1000-fold more potent as an antagonist of A1 than of A2 adenosine receptors. While most substitutions on the 8-cycloalkyl moiety caused decreased potency to inhibit both A1 and A2 adenosine receptors, 8-[trans-4-(acetamidomethyl)cyclohexyl]-1,3-dipropylxanthine was nearly equipotent as an antagonist of the two receptors and appeared to be the most potent antagonist of A2 adenosine receptors reported
