Dicoumarol is a hydroxycoumarin that is methane in which two hydrogens have each been substituted by a 4-hydroxycoumarin-3-yl group. Related to warfarin, it has been used as an anticoagulant. It has a role as an anticoagulant, an EC 1.6.5.2 [NAD(P)H dehydrogenase (quinone)] inhibitor, a vitamin K antagonist and a Hsp90 inhibitor.

Coumarin is an anticoagulant and photoprotective drug; it also has antiulcerogenic activity, which may influence the secretion control mediated by the parasympathetic system. Coumarin is a potent inducer of aflatoxin B1-aldehyde reductase, has chemoprevention of aflatoxin B1 hepatocarcinogenesis. Coumarin is a chromenone having the keto group located at the 2-position. It has a role as a fluorescent dye, a plant metabolite and a human metabolite.

Glycycoumarin is an estrogen agonist, it shows moderate inhibitory effects against CYP1A2 and CYP2B6. Glycycoumarin has anti-liver cancer, neuroprotective, antioxidant and anti-inflammatory activities. Glycycoumarin has anti-hepatitis C virus (HCV) activity, with the IC(50) value of 8.8, ug/mL. Glycycoumarin has an inhibitory effect on smooth muscle contraction induced by various types of stimulants through the inhibition of PDEs, especially isozyme 3, followed by the accumulation of intracellular cAMP; it also can inhibit hepatocyte lipoapoptosis through activation of autophagy and inhibition of ER stress/GSK-3-mediated mitochondrial pathway. Glycycoumarin is a member of the class of coumarins that is coumarin substituted by a hydroxy group at position 7, a methoxy group at position 5, a prenyl group at position 6 and a 2,4-dihydroxyphenyl group at position 3. Isolated from Glycyrrhiza uralensis, it exhibits antispasmodic activity. It has a role as an antispasmodic drug and a plant metabolite. It is a member of coumarins, a member of resorcinols and an aromatic ether.

Trans-beta-D-glucosyl-2-hydroxycinnamic acid is a glucosyl hydroxycinnamic acid. It is a conjugate acid of a trans-beta-D-glucosyl-2-hydroxycinnamate.

Inhalation challenge with capsaicin and rapid intravenous injection of Lobelin and alinamin indicated that peripheral c-fiber receptors were involved in the induction of coughing. Lobeline hydrochloride is an organic molecular entity. It has a role as a cholinergic drug.
