Discovery of a Novel Series of Biphenyl Benzoic Acid Derivatives as Potent and Selective Human β<sub>3</sub>-Adrenergic Receptor Agonists with Good Oral Bioavailability. Part I
A novel class of biphenyl analogues containing a benzoic acid moiety based on lead compound 8i have been identified as potent and selective human beta 3 adrenergic receptor (beta 3-AR) agonists with good oral bioavailability and long plasma half-life. After further substituent effects were investigated at the terminal phenyl ring of lead compound 8i, we have discovered that more lipophilic substitution
