Semilogaritmic plot of molar concentrations of SAR407899 against in vitro relaxation of human 3 μM phenylephrine-precontracted corpus cavernosum. The relaxing effect of SAR407899A is reported on the vertical axis as a percentage of the maximal relaxation induced by papaverine (0.1 mM). The experiment was done with 0.3 mM L-NAME. Points are the mean of five different preparations.
