  Regioselective nitration of purine nucleosides: synthesis of 2-nitroadenosine and 2-nitroinosine

  摘要：

  Nitration reactions of 6-substituted purine nucleosides with tetrabutylammonium nitrate/trifluoroacetic anhydride (TBAN/TFAA) have been studied. This nitrating mixture selectively nitrates C-6 substituted purines at the 2-position, but the method is limited to substrates without NH or OH substituents. Acetylated 6-chloropurine riboside was cleanly nitrated (DCM, 0 degrees C, 71%) and converted to nitro substituted adenosine and inosine in a few simple steps. (C) 2000 Elsevier Science Ltd.

  Synthesis and properties of 2-nitrosoadenosine

  摘要：

  一系列新的2取代腺苷衍生物是通过与2-亚硝基腺苷三乙酸酯4进行加成和缩合反应合成的。腺苷亚硝基功能团的优异反应性通过与烯烃（4 + 2环加成反应）、环己烯（“烯”反应）、呋喃（加成/重排反应）和苯胺（米尔斯偶联）等反应得到了证明。2-亚硝基腺苷三乙酸酯是通过对6-氯嘌呤核苷三乙酸酯进行2位的硝化反应，然后再对硝基进行还原/氧化反应合成的。4的脆弱亚硝基功能团需要通过与环戊二烯进行4 + 2环加成反应进行保护，以使RNA环的去酰化成为可能。在95°C下，去酰化产物的反向Diels-Alder反应生成了标题化合物2-亚硝基腺苷7。通过改变温度、浓度和溶剂，研究了三乙酸酯4的亚硝基功能团的二聚化过程。特别是，温度的变化对这种二聚化反应起到了控制作用：在65°C时为100%单体，在-20°C时则完全二聚化。

  Four subtypes of adenosine receptors are currently known, that is, A(1), A(2A), A(2B), and A(3) receptors. Interestingly, quite substantial species differences exist especially between human and rat A(3) receptors. As a result, ligands such as CCPA, which are very selective for the rat A(1) and A(3) receptor versus the human A(3) receptor, are substantially less selective when the human A(1) and A(3) receptors are compared. New 2-substituted and 2,N-6-disubstituted adenosines were synthesized, and their affinities for the human adenosine A(1), A(2A), A(2B), and A(3) receptors were determined. Although large substituents on the C2-position are generally thought to yield adenosine A(2A) receptor selective ligands, the reported series of 2-triazeno-substituted adenosines had a very high affinity for the A(1) receptor. For example, 2-(3-phenylaminocarbonyltriazene-1-yl)adenosine had an affinity of 6.1 +/- 1.3 nM for the human adenosine A(1) receptor. Introduction of a diphenethyl substituent at the N-6-position of this compound resulted in a high-affinity agonist, 3.1 +/- 0.9 nM, for the human adenosine A(1) receptor with 316- and 45-fold selectivity versus the human A(2A) and human A(3) receptors, respectively. The most selective, high-affinity human adenosine A(1) receptor agonist was the disubstituted compound N-6-cyclopentyl-2-(3-phenylaminocarbonyltriazene-1-yl)adenosine (TCPA). TCPA had an affinity of 2.8 +/- 0.8 nM for the human adenosine A, receptor and was 75-fold and 214-fold selective versus the human A(2A) and human A(3) receptors, respectively. In addition, TCPA was a full agonist and inhibited the forskolin-induced cAMP production of CHO cells stably transfected with the human adenosine A(1) receptor with an IC50 of 1.5 +/- 0.5 nM.

  The influence of nitro substituents on the properties of adenosine and 1-deazaadenosine was studied. Combination of a nitro group at the 2-position with several N-6 substituents such as cyclopentyl and m-iodobenzyl gave a series of analogues with good adenosine receptor affinity, showing directable selectivity for the A(1), A(2A) and A(3) adenosine receptor subtypes.
