Preclinical profile of PF9404C, a nitric oxide donor with beta receptor blocking properties.


PF9404C ((2'S),(2S)-3-isopropylamine, 1-[4-(2,3-dinitroxy)propoxymethyl]-phenoxy-2'-propranol) is the S-S diesteroisomer of a novel blocker of beta-adrenergic receptors with vasorelaxing properties. It causes a concentration-dependent relaxation of rat aorta helical strips precontracted with 10(-6) M norepinephrine (NE; IC50 33 nM). It is equipotent to… (More)
