(±)-Naringenin (Naringenine) is a natural product. It displays vasorelaxant effect on endothelium-denuded vessels via the activation of BKCa channels in myocytes.

Ethyl cinnamate has antifungal, and vasorelaxant effects. Ethyl cinnamate can lead to the damage of cell membrane system and metabolic disorder through inducing lipid peroxidation via initiating ROS overproduction. Ethyl cinnamate can inhibit the tonic contractions induced by high K+ and phenylephrine (PE) in a concentration-dependent manner, with respective IC50 values of 0.30 mM and 0.38 mM.

Saucerneol has significant cardiovascular effects such as vasorelaxant and negative inotropic actions.

Cistanoside F shows vasorelaxant, and antioxidative effects, it shows a strong free radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and xanthine/xanthine oxidase (XOD) generated superoxide anion radical (O2-.).

(+)-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].

(R)-IDHP, an isomer of IDHP and a metabolite of salvia, exhibits vasorelaxant properties by inhibiting calcium (Ca 2+) release and inward flow through both voltage-dependent and receptor-operated calcium channels in vascular smooth muscle cells. It is utilized in cardiovascular disease research [1].

Leachianone G exhibits significant antioxidant potentials in the ABTS, ONOO(-), and total ROS assays, it also shows inhibitory activities against pancreatic lipase, it may be used as drug candidate to control obesity. Leachianone G shows potent antiviral

Villocarine A, an indole alkaloid with natural vasorelaxant properties [1], is a chemical compound known for its ability to relax blood vessels.

Evocarpine shows antimycobacterial, and vasorelaxant effects, it can inhibit Ca2+ influx through voltage-dependent calcium channels.

Ayanin has vasorelaxant activity, it also may have the potential for use in treating allergic asthma.The IC(50) value of Ayanin (quercetin-3,7,4'-O-trimethylether) is 2.2microM for inhibiting interleukin (IL)-4 production from purified basophils.

Tilifodiolide exerts in vitro and in vivo anti-inflammatory activity and in vivo antinociceptive effects. Tilifodiolide exerted antidiarrheal activity by decreasing the intestinal fluid accumulation and vasorelaxant effects mediated by nitric oxide and cyclic guanosine monophosphate, it also showed anxiolytic and antidepressant effects by the partial involvement of gamma-Aminobutyric acid (GABA) receptors and the possible participation of α2-adrenoreceptors, respectively.

ent-3-Acetoxy-labda-8(17),13-dien-15-oic acid have vasorelaxant and hypotensive actions, the mechanisms underlying the cardiovascular actions of the labdane involve the activation of the endothelial NO-cGMP pathway, the opening of K+ channels and the alteration on Ca2+ mobilization.

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.

Methyl cinnamate, a tyrosinase inhibitor and a flavoring compound, has antimicrobial, antiadipogenic, vasorelaxant, and anti-inflammatory effects.

Uvaol is present in olives and virgin olive oil with anti-inflammatory, anti-proliferative, and vasorelaxant activities.

GS 389 is a novel tetrahydroisoquinoline analog with vasorelaxant properties. GS-389 significantly inhibited cGMP phosphodiesterase from the rabbit brain and increased cGMP levels in the rat aorta.
