  Structure-Activity Relationships of 9-Alkyladenine and Ribose-Modified Adenosine Derivatives at Rat A3 Adenosine Receptors

  摘要：

  9-Alkyladenine derivatives and ribose-modified N-6-benzyladenosine derivatives were synthesized in an effort to identify selective ligands for the rat A(3) adenosine receptor and leads for the development of antagonists. The derivatives contained structural features previously determined to be important for A(3) selectivity in adenosine derivatives, such as an N-6-(3-iodobenzyl) moiety, and were further substituted at the 2-position with halo, amino, or thio groups. Affinity was determined in radioligand binding assays at rat brain A(3) receptors stably expressed in Chinese hamster ovary (CHO) cells, using [I-125]]AB-MECA (N-6-(4-amino-3-iodobenzyl)adenosine-5'-(N-methyluronamid)), and at rat brain A(1) and A(2a) receptors using [H-3]-N-6-PIA ((R)-N-6-phenylisopropyladenosine) and [H-3]CGS 21680 (2-[[[4-(2-carboxyethyl)-phenyl]ethyl]amino]-5'-(N-ethylcarbamoyl)adenosine), respectively. A series of N-6-(3-iodobenzyl) 2-amino derivatives indicated that a small 2-alkylamino group, e.g., methylamino, was favored at A(3) receptors. N-6-(3-Iodobenzyl)-9-methyl-2-(methylthio)adenine was 61-fold more potent than the corresponding 2-methoxy ether at A(3) receptors and of comparable affinity at A(1) and A(2a) receptors, resulting in a 3-6-fold selectivity for A(3) receptors. A pair of chiral N-6-(3-iodobenzyl) 9-(2,3-dihydroxypropyl) derivatives showed stereoselectivity, with the R-enantiomer favored at A(3) receptors by 5.7-fold. 2-Chloro-9-(beta-D-erythrofuranosyl)-N-6-(3-iodobenzyl)adenine had a K-i value at A(3) receptors of 0.28 mu M. 2-Chloro-9-[2-amino-2,3-dideoxy-beta-D-5-(methylcarbamoyl)-arabinofuranosyl]-N-6-(3-iodobenzyl)adenine was moderately selective for A(1) and A(3) VS A(2a) receptors. A 3'-deoxy analogue of a highly A(3)-selective adenosine derivative retained selectivity in binding and was a full agonist in the inhibition of adenylyl cyclase mediated via cloned rat A(3) receptors expressed in CHO cells. The 3'-OH and 4'-CH2OH groups of adenosine are not required for activation at A(3) receptors. A number of 2',3'-dideoxyadenosines and 9-acyclic-substituted adenines appear to inhibit adenylyl cyclase at the allosteric ''P'' site.

  The present invention provides A.sub.3 selective agonists, particularly, adenine compounds having selected substituents at the 2, 6, and 9 positions, and related substituted compounds, particularly those containing substituents on the benzyl and/or uronamide groups, as well as pharmaceutical compositions containing such compounds. The present invention also provides a method of selectively activating an A.sub.3 adenosine receptor in a mammal, which method comprises acutely or chronically administering to a mammal in need of selective activation of its A.sub.3 adenosine receptor a therapeutically or prophylactically effective amount of a compound which binds with the A.sub.3 receptor so as to stimulate an A.sub.3 receptor-dependent response.

  本发明提供了A.sub.3选择性激动剂，特别是在2、6和9位置具有选择性取代基的腺嘌呤化合物，以及相关的取代化合物，特别是那些在苄基和/或糖酰胺基团上含有取代基的化合物，以及包含这些化合物的药物组合物。本发明还提供了一种在哺乳动物中选择性激活A.sub.3腺苷受体的方法，该方法包括向需要选择性激活其A.sub.3腺苷受体的哺乳动物急性或慢性地给予与A.sub.3受体结合以刺激A.sub.3受体依赖性反应的治疗或预防有效量的化合物。
