  2-(Arylalkylamino)adenosin-5'-uronamides: a new class of highly selective adenosine A2 receptor ligands

  摘要：

  The synthesis and receptor-binding profiles at adenosine receptor subtypes for a series of 2-(arylalkylamino)-adenosin-5'-uronamides is described. Halogenated 2-phenethylamino analogues such as 3e show greater than 200-fold selectivity for the A2 receptor subtype on the basis of rat brain receptor binding. The general structure-activity relationship of this series of compounds is discussed both in terms of potency at A2 receptors as well as receptor subtype selectivity. It is possible to introduce a hydrophilic carboxyalkyl substituent to this series such as in CGS 21680A (3h) and still retain good potency and selectivity for A2 receptors. In addition, functional data in a perfused working rat heart model shows that these compounds possess full agonist properties at A2 receptors with 3h having a greater than 1500-fold separation between A2 (coronary vasodilatory) and A1 (negative chronotropic) receptor mediated events.

  A series of adenosine-5′-N-alkylcarboxamides and N6-(2,2-diphenylethyl)adenosine-5′-N-alkylcarboxamides bearing antioxidant moieties in the 2-position were synthesized from the versatile intermediate, O6-(benzotriazol-1-yl)-2-fluoro-2′,3′-O-isopropylideneinosine-5′-N-alkylcarboxamide (1). These compounds were evaluated as A2A adenosine receptor (A2AR) agonists in a cAMP accumulation assay, and a number

  Herein we report both linear and convergent pathways for the preparation of 2-alkynyl substituted adenosine-5'-N-ethylcarboxamides via the versatile synthetic intermediate, 2-iodoadenosine-5'-N-ethylcarboxamide (13). The linear approach afforded 13 in an overall yield of 30% from guanosine over eight synthetic steps. The convergent approach was shorter, but proceeded in lower yield (five steps, 20% yield). Both approaches compare favourably with previously reported syntheses of 13, which has been prepared in 15% yield from guanosine over nine steps. 2-Iodoadenosine-5'-N-ethylcarboxamide (13) was subsequently converted to HENECA (2) and PHPNECA (3) to exemplify the utility of this approach for the preparation of potent A(2A) adenosine receptor agonists. The linear approach was also amenable to the synthesis of 2-fluoropurine ribosides, which were subsequently elaborated into 2-alkylaminoadenosine-5'-N-ethylcarboxamides. Furthermore, both of these synthetic approaches are readily amenable to the synthesis of adenosine analogues with varied 2-, 6- and 5'-substitution patterns. (c) 2009 Elsevier Ltd.
