Design, synthesis, and biological evaluation of structurally constrained hybrid analogues containing ropinirole moiety as a novel class of potent and selective dopamine D3 receptor ligands

Two series of hybrid analogues were designed, synthesized, and evaluated as a novel class of selective ligands for the dopamine D3 receptor. Binding affinities of target compounds were determined (using the method of radioligand binding assay). Compared to comparator agent BP897, compounds 2a and 2c were found to demonstrate a considerable binding affinity and selectivity for D3 receptor, and especially compound 2h was similarly potent and more selective D3R ligand than BP897, a positive reference. Thus, they may provide valuable information for the discovery and development of highly potent dopamine D3 receptor ligands with outstanding selectivity.

A convenient synthesis of 4-(2-hydroxyethyl)indolin-2-one, a useful intermediate for the preparation of both dopamine receptor agonists and protein kinase inhibitors

This paper describes a practical approach to the preparation of 4-(2-hydroxyethyl)indolin-2-one, a key intermediate in the synthesis of dopaminergic agonists such as ropinirole - a drug used in the treatment of Parkinson's disease and restless legs syndrome - and of two sets of protein kinase inhibitors. The sequence starts from commercially available 2-(2-methyl-3-nitrophenyl)acetic acid, which is converted in five steps into the desired target compound. This procedure offers a convenient alternative route to existing methodologies, given its milder reaction conditions, ease of implementation, and its overall yield (59 %).
