Norbormide BiologicalActivity

Description	Norbormide shows vasoconstrictor activity by blocking calcium channel. The activity of Norbormide is species- and tissue-specific, endothelium independent, and is restricted to the peripheral arteries of rat. Norbormide is also a toxicant, and the oral LD50s in mouse, hamster, guinea pig and rabbit are 2250, 140, 620, and 1000 mg/kg[1].
