A series of purine ribonucleosides with chiral amino acid amides were synthesized and their affinity for A(1) adenosine receptors (A(1)ARs) was investigated. It was found that some of the synthesized nucleosides exhibited partial agonist activity towards A(1)ARs and showed different profiles of psychoactive action and ocular hypotensive effect.
A series of purine ribonucleosides bearing chiral amino acid amides at the C6 position of 2-chloropurine was synthesized. Molecular docking of the synthesized analogs of 2-chloroadenosine by their affinity for A(1) adenosine receptors (A(1)ARs) was conducted. The investigation of A(1)AR stimulating activity of synthesized nucleosides was carried out in a model of an isolated mouse atrium. We have shown that derivatives with tyrosine, valine, and serine residues exhibit the properties of A(1)AR partial agonists. Animal experiments in the open field test have shown that these compounds have different profiles of psychoactive action. These nucleosides have an ophthalmic hypotensive effect and reduce intraocular pressure in a manner slightly inferior to that of timolol and brimonidine. The synthesized nucleosides can be the basis for further design and synthesis of new A(1)AR agonists.
