β-Aminopropionitrile (3-Aminopropionitrile) is a selective inhibitor of lysyl oxidase.

Harmalol hydrochloride (Harmidol hydrochloride) is a β-carboline alkaloid that can be extracted from the seeds of Peganum harmala L. Harmalol hydrochloride is the major metabolite of Harmaline and significantly inhibits dioxin-mediated induction of CYP1A1 at both transcriptional and post-translational levels. Harmalol hydrochloride showed vasorelaxant activity in isolated rat thoracic aortic preparations preconstricted with phenylephrine or KCl. Harmalol hydrochloride has antioxidant activity.

3-Deoxysappanone B has vasorelaxation effects, it can mediate endothelium- independent vasodilator action in rat thoracic aortic rings.

1. Yunaconitine (Guayewuanine B) has anti-inflammatory and analgesic actions. 2. Yunaconitine was shown to have anti-thermic effect in pyrexial rats when administered orally at a dose of 5 μg/kg. 3. Yunaconitine shows positive effect in the granuloma inhibition test when it was subcutaneously injected, 1 μg/kg for 6 d, or added directly to the cotton-pellet. 4. Yunaconitine inhibited the increased vascular permeability caused byacetic acid and histamine, the leucocyte migratory response induced by injection of 1 % carrageenin .1 ml in rat's thoracic cavity.

(+)-Osbeckic acid, extracted from Tartary Buckwheat, acts as a vasorelaxant and demonstrates a significant vasorelaxant effect in Sprague-Dawley rat thoracic aorta rings, with an EC50 value of 887 μM [1].
