3-O-Methylquercetin is a selective and competitive PDE3/PDE4 inhibitor, and inhibits PDE3 than PDE4 with a low K(m) value; it inhibits total cAMP- and cGMP-phosphodiesterase (PDE) of guinea pig trachealis at low concentrations. 3-O-Methylquercetin has antiviral, anti-inflammatory and bronchodilating effects, and has the potential for use in the treatment of asthma at a dose without affecting blood pressure.
Theophylline is a competitive nonselective phosphodiesterase inhibitor and nonselective adenosine receptor antagonist, which is the most widely used anti-asthma drug worldwide and is classified as a bronchodilator. It has antiinflammatory, and immunomodulatory actions, it also can antagonize flurazepam-induced depression of cerebral cortical neurons.
Peimisine may have antihypertensive action, it can inhibit angiotensin I converting enzyme activity in a dose-dependent manner(the IC50 value of 526.5 microM). Peimisine can affect M-receptor, excit β-receptor, restrain the release of internal calcium, and promote to releaseing nitrogen monoxidum in order to relax tracheal smooth muscle and relieve asthma. It plays a protective role against LPS-induced acute lung injury, and against the experimental hepatic fibrosis formation.
Vasicinone may act as a hepatoprotective agent. (±)-Vasicinone has significant antitussive, expectorant, and bronchodilating activities, which can be used to treat respiratory disease.(S)-Vasicinone exhibits antiproliferative activity against human gastric cancer cells MCG-803.
Glaucine has antitussive, antioxidative potential and antiviral activities, it may be an anti-arthritic agent, it can enhance LPS and zymosan-induced IL-10 production. Glaucine can inhibit the migration and invasion of human breast cancer cells by MMP-9 inhibitory activity, attenuating IκBα and NF-κB activities.
Vincamine is a plant alkaloid used clinically as a peripheral vasodilator that increases cerebral blood flow and oxygen and glucose utilization by neural tissue to combat the effect of aging. Vincamine has contractile and relaxant actions on the guinea pig trachealis, may be due to the generation of prostaglandins and to changes in the membrane Ca2+ fluxes and/or the intracellular Ca2+ distribution. Vincamine alleviates Amyloid-β 25-35 peptides-induced cytotoxicity in PC12 cells.
Peucedanocoumarin II shows only partial relaxation.
Isokaempferide shows hepatoprotective, antiproliferative, and anti-inflammatory effects, the anti-inflammatory effects can be explained, at least in part, by reducing neutrophil degranulation, myeloperoxidase activity, mediators as well as TNF-alpha secretion. Isokaempferide is used as a bronchodilator, can induce relaxation of guinea-pig isolated trachea.
