Synthesis and Pharmacological Activities of 2-(3'-substituted-2'-hydroxypropylamino)pyridines.

In the present study, a series of 2-(3'-substituted-2'-hydroxypropylamino)pyridines were synthesized and characterized by IR, 1H-NMR and elemental analysis. The compounds were investigated for anticonvulsant (150, 300 mg/kg) and cardiac activity. 2-(3'-Diethylamino-2'-hydroxypropylamino)pyridine 3 was found to exhibit the highest anticonvulsant activity. 2-(3'-Dimethylamino-2'-hydroxypropylamino)pyridine 2 and 2-[3'-(4''-nitrophenylamino)-2'-hydroxypropylamino]pyridine 6 were found to exhibit negative ionotropic activity. 2-(3'-Dimethylamino-2'-hydroxypropylamino)pyridine 2, 2-[3'-(4''-nitrophenylamino)-2'-hydroxypropylamino]pyridine 6 and 2-(3'-piperidino-2'-hydroxypropylamino)pyridine 8 were found to antagonize exhibit beta-adrenergic activity.
