  Replacement of amide with bioisosteres led to a new series of potent adenosine A2A receptor antagonists

  摘要：

  We have previously reported a series of 2,4,6-trisubstituted pyrimidines as potent A(2A) receptor antagonists. The leading compounds often feature a potentially labile acetamide functional group which tends to hydrolyze under acidic conditions. Here we report the replacement of the acetamide functional group with bioisosteres. This effort led us to a new series of adenosine A(2A) receptor antagonists with improved potency and chemical stability. (C) 2013 Elsevier Ltd. All rights reserved.

  Parkinson's disease is a neurodegenerative disease characterized by the motor symptoms of bradykinesia, tremor, and rigidity. Current therapies are based mainly on dopaminergic replacement strategies by administration of either dopamine agonists or dopamine precursor levodopa (L-Dopa). These treatments provide symptomatic relief without slowing or stopping the disease progression, and long-term usage of these drugs is associated with diminished efficacy, motor fluctuation, and dyskinisia. Unfortunately, there had been few novel treatments developed in the past decades. Among nondopaminergic strategies for the treatment of Parkinson's disease, antagonism of the adenosine A2A receptor has emerged to show great potential. Here we report the optimization of a new chemical scaffold, which achieved exceptional receptor binding affinity and ligand efficiency against adenosine A2A receptor. The leading compounds demonstrated excellent efficacy in the haloperidol induced catalepsy model for Parkinson's disease.
