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.

In the present article, we report on a strategy to improve the physical properties of a series of small molecule human adenosine 2A (hA(2A)) antagonists. One of the aromatic rings typical of this series of antagonists is replaced with a series of aliphatic groups, with the aim of disrupting crystal packing of the molecule to lower the melting point and in turn to improve the solubility. Herein, we describe the SAR of a new series of water-soluble 2,4,6-trisubstituted pyrimidines where R-1 is an aromatic heterocycle, R-2 is a short-chain alkyl amide, and the typical R-3 aromatic heterocyclic substituent is replaced with an aliphatic amino substituent. This approach significantly enhanced aqueous solubility and lowered the log P of the system to provide molecules without significant hERG or CYP liabilities and robust in vivo efficacy.
