N6-[(Hetero)aryl/(cyclo)alkyl-carbamoyl-methoxy-phenyl]-(2-chloro)-5′-N-ethylcarboxamido-adenosines: The first example of adenosine-related structures with potent agonist activity at the human A2B adenosine receptor

A new series of N6-[(hetero)aryl/(cyclo)alkyl-carbamoyl-methoxy-phenyl]-(2-chloro)-5′-N-ethylcarboxamido-adenosines (24-43) has been synthesised and tested in binding assays at hA1, hA2A and hA3 adenosine receptors, and in a functional assay at the hA2B subtype. The examined compounds displayed high potency in activating A2B receptors with good selectivity versus A2A subtypes. The introduction of an unsubstituted 4-[(phenylcarbamoyl)-methoxy]-phenyl chain at the N6 position of 5′-N-ethylcarboxamido-adenosine led us to the recognition of compound 24 as a full agonist displaying the highest efficacy of the series (EC50 hA2B = 7.3 nM). These compounds represent the first report about adenosine-related structures capable of activating hA2B subtype in the low nanomolar range.

The reduction of aromatic nitro groups on solid supports using sodium hydrosulfite (Na2S2O4)

An improved method for reducing aromatic nitro compounds on solid-phase supports using sodium hydrosulfite is presented. Conditions have been optimized to enable the use of this reagent for reductions on both polyethyleneglycol-polystyrene (PEG) resins an
