Adenine derivatives bearing substituents in the 2-, N6-, 7-, 8-, and/or 9-position and a series of deazapurines were synthesized and investigated in [3H]adenine binding studies at the adenine receptor in rat brain cortical membrane preparations (rAde1R). Steep structure-activity relationships were observed. Substitution in the 8-position (amino, dimethylamino, piperidinyl, piperazinyl) or in the 9-position (2-morpholinoethyl) with basic residues or introduction of polar substituents at the 6-amino function (hydroxy, amino, acetyl) represented the best modifications. Functional evaluation of selected adenine derivatives in adenylate cyclase assays at 1321N1 astrocytoma cells stably expressing the rAde1R showed that all compounds investigated were agonists or partial agonists. A subset of compounds was additionally investigated in binding studies at human embryonic kidney (HEK293) cells, which also express a high-affinity adenine binding site. Structure-affinity relationships at the human cell line were similar to those at the rAde1R, but not identical. In particular, N 6-acetyladenine (25, Ki rat: 2.85 μM; Ki human: 0.515 μM) and 8-aminoadenine (33, Ki rat: 6.51 μM; Ki human: 0.0341 μM) were much more potent at the human as compared to the rat binding site. The new AdeR ligands may serve as lead structures and contribute to the elucidation of the functions of the adenine receptor family. 2009 American Chemical Society.

The regioselectivity of isomer formation in the reaction of 8-substituted adenines with glycidol depends on steric factors of substituents.The compounds prepared were tested for immunostimulating activity.
EASY ALKYLATION OF PURINE BASES BY SOLID-LIQUID PHASE TRANSFER CATALYSIS WITHOUT SOLVENT. STRUCTURAL ANALYSIS BY 2D HETERONUCLEAR 1H 13C CORRELATED NMR SPECTROSCOPY

Solid-liquid PTC without added organic solvent promotes alkylation of purine derivatives leading in particular to an efficient synthesis of the antiviral DHPA.The location of the substituent on the ring was determined by analysis of coupling interactions
