چکیده انگلیسی
A series of dithiobenzanilide derivatives was synthesized and each compound was evaluated for its ability to reduce KCl-induced contractions of smooth muscle preparations of the guinea pig. Starting from a recent publication describing benzanilide derivatives as antispasmodic agents, structure-activity guided synthesis was performed to obtain compounds with improved spasmolytic activity. First, compounds with two amide bonds were designed and second, both amide oxygens were replaced by two sp2 sulfur atoms resulting in dithiobenzanilide derivatives. The most potent antispasmodic dithiobenzanilide 19 showed improved activity with an IC50 value of 0.4 μM. Moreover, the study also demonstrated that these active compounds were able to antagonize the effect of spasmogens like acetylcholine and phenylephrine and that the activity is not mediated by activation of ATP-dependent potassium channels (KATP-channels) or inhibition of endothelial nitric oxide synthase (eNOS).
