Identification of Novel, Water-Soluble, 2-Amino-N-pyrimidin-4-yl Acetamides as A2A Receptor Antagonists with In Vivo Efficacy
摘要:
Potent adenosine hA(2A) receptor antagonists are often accompanied by poor aqueous solubility, which presents issues for drug development. Herein we describe the early exploration of the structure-activity relationships of a lead pyrimidin-4-yl acetamide series to provide potent and selective 2-amino-N-pyrimidin4-yl acetamides as hA(2A) receptor antagonists with excellent aqueous solubility. In addition, this series of compounds has demonstrated good bioavailability and in vivo efficacy in a rodent model of Parkinson's disease, despite having reduced potency for the rat A(2A) receptor versus the human A2A receptor.
2-Amino-N-pyrimidin-4-ylacetamides as A2A Receptor Antagonists: 1. Structure−Activity Relationships and Optimization of Heterocyclic Substituents
摘要:
Previously we have described a novel series of potent and selective A(2A) receptor antagonists (e.g., 1) with excellent aqueous solubility.(1) While these compounds are efficacious A(2A) antagonists in vivo, the presence of an unsubstituted furyl moiety was a cause of some concern. In order to avoid the potential metabolic liabilities that could arise from an unsubstituted fury] moiety, an optimization effort was undertaken with the aim of replacing the unsubstituted furan with a more metabolically stable group while maintaining potency and selectivity. Herein, we describe the synthesis and SAR of a range of novel heterocyclic systems and the successful identification of a replacement for the unsubstituted furan moiety with a methylfuran or thiazole moiety while maintaining potency and selectivity.
