In a search for novel analogues of β3-adrenoceptor (AR) agonists relaxing the bladder for treatment of urinary dysfunction, 2-[4-(2-{[(1S,2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]amino}ethyl)phenoxy]-2-methylpropionic acids (1a–e), into which a fibrate-like structure had been incorporated, were synthesised. Compound 1a was found to be a selective β3-AR agonist in functional assays using the ferret detrusor (β3-AR), rat uterus (β2-AR), and rat atrium (β1-AR); β3: EC50
