Description
Summary:[Display omitted] From a collection containing more than 1500 academic compounds, in silico screening identified a hit for the human A1 adenosine receptor containing a new purine scaffold. To study the structure activity relationships of this new chemical series for adenosine receptors, a library of 24 purines was synthesized and tested in radioligand binding assays at human A1, A2A, A2B and A3 adenosine receptor subtypes. Fourteen molecules showed potent antagonism at A1, A3 or dual A1/A3 adenosine receptors. This purine scaffold is an important source for novel biochemical tools and/or therapeutic drugs.
