Überblick
(+)-abscisic acid is the naturally occurring (1'S)-(+) enantiomer of abscisic acid. It is an important sesquiterpenoid plant hormone which acts as a regulator of plant responses to environmental stresses such as drought and cold. It has a role as a plant hormone and a plant metabolite. It is a conjugate acid of a (+)-abscisate. It is an enantiomer of a (-)-abscisic acid.

Pharmakologische Informationen
MeSH Pharmacological Classification
Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
Drugs used to prevent NAUSEA or VOMITING.
Drugs used to induce SLEEP, prevent SLEEPLESSNESS, or treat SLEEP INITIATION AND MAINTENANCE DISORDERS.
Drugs that selectively bind to but do not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine. Included here are the classical antihistaminics that antagonize or prevent the action of histamine mainly in immediate hypersensitivity. They act in the bronchi, capillaries, and some other smooth muscles, and are used to prevent or allay motion sickness, seasonal rhinitis, and allergic dermatitis and to induce somnolence. The effects of blocking central nervous system H1 receptors are not as well understood.
Drugs used to induce drowsiness or sleep or to reduce psychological excitement or anxiety.
Any of the hormones produced naturally in plants and active in controlling growth and other functions. There are three primary classes: auxins, cytokinins, and gibberellins.
Anwendungen
Verwenden(+)-Abscisic acid is the natural isomer of the abscission-accelerating plant hormone and a plant growth regulator that exhibits multiple physiological effects, including inducing plant dormancy, inhibiting seed germination and plant growth, and stimulating stomatal closure.
