Synthesis and in vitro evaluation of ambrisentan analogues as potential endothelin receptor antagonists
摘要:
A series of novel 2-[(4,6-dimethylpyrimidin-2-yl)oxy]-3,3-diphenyl butyric acid derivatives were synthesized and evaluated for their antagonistic activity for endothelin-1-induced contraction in rabbit aorta. Within this series of compounds, 2-[(4,6-dimethylpyrimidin-2-yl) oxy]-3-cyano-3,3-diphenylpropionic acid (4) displays comparable potency with ambrisentan (1), and warrants further investigation.
