Abstract
Traditionally, molecular recognition between the orthosteric site of adenosine receptors and their endogenous ligand occurs with a 1:1 stoichiometry. Inspired by previous mechanistic insights derived from Supervised Molecular Dynamics (SuMD) simulations, which suggested an alternative 2:1 binding stoichiometry, we synthesized BRA1, a bis-ribosyl adenosine derivative, tested its ability to bind to and activate the members of the adenosine receptors family, and rationalized its activity through molecular modeling.
