Abstract
The four stereoisomers of 4-(dimethylamino)-2-phenyl-(2-pyridyl)pentanamide were synthesized, and the absolute configurations were determined by X-ray crystallography. Pharmacological testing for anticholinergic activity revealed great differences in potency among 10 (2R,4R,IC50 = 0.40 microM), 11 (2S,4S,31 microM), 12 (2R,4S,170 microM), and 13 (2S,4R,0.13 microM). A new drug application for the racemate 8 (FK176, vamicamide) has been filed in Japan for the treatment of overactive detrusor syndrome.
