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.

-
Paragraph 0068; 0069, (2016/10/08)
The invention discloses an indoline-2-ketone D3 receptor ligand, which is a compound as shown in the formula I or pharmaceutical salt thereof, wherein n=2 or 3; R represents H, 4-CH3, 2,3-diCH3, 2-CH3, 4-OCF3, 3-OCH3, 3,4-diCH3 or 4-Cl. In comparison with the prior art, the compound has a strong activity to a dopamine D3 receptor, is used in treating or preventing central nervous and metal diseases such as schizophrenia, Parkinson's disease, drug dependence and relapse, etc., can be used in neuroprotection, and is used as a tool drug for researching D3 receptor structure, function and diseases related to D3 receptor dysfunction.

A relatively new strategy in drug discovery is the development of dual acting ligands. These molecules are potentially able to interact at two orthosteric binding sites of a heterodimer simultaneously, possibly resulting in enhanced subtype selectivity, higher affinity, enhanced or modified physiological response, and reduced reliance on multiple drug administration regimens. In this study, we have successfully synthesized a series of classical heterobivalent ligands as well as a series of more integrated and drug-like dual acting molecules, incorporating ropinirole as a dopamine D2 receptor agonist and ZM 241385 as an adenosine A2A receptor antagonist. The best compounds of our series maintained the potency of the original pharmacophores at both receptors (adenosine A2A and dopamine D2). In addition, the integrated dual acting ligands also showed promising results in preliminary blood-brain barrier permeability tests, whereas the classical heterobivalent ligands are potentially more suited as pharmacological tools.
