    9-(β-D-Ribosfuranosyluronamide)adenine derivatives that are selective agonists and antagonists of the A3 adenosine receptor (AR) have been derivatized as prodrugs for in vivo delivery. The free hydroxy groups at the 2' and 3' positions of the agonists 2-chloro-N6-(3-iodobenzyl)-9-(N-methyl-(β-D-ribosfuranosyluronamide)adenine 2b, the corresponding 4'-thio nucleoside 2c, and antagonists 4a and 4b (5'-N,N-dimethylamides related to 2b and 2c, respectively) were derivatized through simple acylation reactions. The prodrug derivatives were tested in radioligand binding assays at ARs and in a functional assay of adenylate cyclase at the A3AR and found to be considerably less active than the parent drugs. The hydrolysis of nucleoside 2',3'-diesters to regenerate the parent compound in the presence of human blood was demonstrated. 2',3'-Dipropionate esters of 2b and 4a were readily cleaved in a two-step reaction to regenerate the parent drug, on a time scale of two hours. The cleavage of a 2',3'-dihexanoate ester occurred at a slower rate. This indicates that the prodrugs are suitable as masked forms of the biologically active A3AR agonists and antagonists for future evaluation in vivo.

    9-(β-D-Ribosfuranosyluronamide)腺嘌呤衍生物被改造成为A3腺苷受体(AR)的选择性激动剂和拮抗剂的前药,用于体内输送。激动剂2-氯-N6-(3-碘苯甲基)-9-(N-甲基-(β-D-核糖呋喃脲酰脲)腺嘌呤2b,对应的4'-硫代核苷2c,以及拮抗剂4a和4b(分别与2b和2c相关的5'-N,N-二甲酰胺)的2'和3'位的游离羟基通过简单的酰基化反应进行了改造。在AR的放射配体结合测定和A3AR腺苷酸环化酶功能测定中,发现这些前药衍生物比原药物活性明显降低。在人类血液中证明了核苷2',3'-二酯的水解可以再生原药物。2',3'-二丙酸丙酯化合物2b和4a可以在两步反应中迅速裂解,再生原药物,时间尺度为两小时。2',3'-二己酸酯的裂解速率较慢。这表明这些前药适合作为生物活性A3AR激动剂和拮抗剂的掩蔽形式,以供未来体内评估。

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

    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.
