Belladonna Alkaloids
Alkaloids obtained from various plants, especially the deadly nightshade (Atropa belladonna), variety acuminata; atropine, hyoscyamine and scopolamine are classical, specific antimuscarinic agents with many pharmacologic actions; used mainly as antispasmodics.
Atropa belladonna
A plant species of the genus ATROPA, family SOLANACEAE that contains ATROPINE; SCOPOLAMINE; BELLADONNA ALKALOIDS and other SOLANACEOUS ALKALOIDS. Some species in this genus are called deadly nightshade which is also a common name for SOLANUM.
Solanaceae
A plant family of the order Solanales, subclass Asteridae. Among the most important are POTATOES; TOMATOES; CAPSICUM (green and red peppers); TOBACCO; and BELLADONNA.
Solanaceous Alkaloids
Alkaloids, mainly tropanes, elaborated by plants of the family Solanaceae, including Atropa, Hyoscyamus, Mandragora, Nicotiana, Solanum, etc. Some act as cholinergic antagonists; most are very toxic; many are used medicinally.
Erythroxylaceae
Alkaloids
Organic nitrogenous bases. Many alkaloids of medical importance occur in the animal and vegetable kingdoms, and some have been synthesized. (Grant & Hackh's Chemical Dictionary, 5th ed)
Datura
A plant genus of the family SOLANACEAE. Members contain TROPANES. The common name of trumpet flower is also sometimes used for GELSEMIUM.
Atropa
A plant genus of the family SOLANACEAE which contain SOLANACEOUS ALKALOIDS including ATROPINE which is named after this genus.
Datura stramonium
A plant species of the genus DATURA, family SOLANACEAE, that contains TROPANES and other SOLANACEOUS ALKALOIDS.
Duboisia
A plant genus of the family SOLANACEAE that is a source of SCOPOLAMINE HYDROBROMIDE and other TROPANES.
Delphinium
A plant genus of the family RANUNCULACEAE. Members contain ACONITINE and other diterpenoid alkaloids.
Materia Medica
Materials or substances used in the composition of traditional medical remedies. The use of this term in MeSH was formerly restricted to historical articles or those concerned with traditional medicine, but it can also refer to homeopathic remedies. Nosodes are specific types of homeopathic remedies prepared from causal agents or disease products.
Hyoscyamus
Ergot Alkaloids
Alkaloids originally isolated from the ergot fungus Claviceps purpurea (Hypocreaceae). They include compounds that are structurally related to ergoline (ERGOLINES) and ergotamine (ERGOTAMINES). Many of the ergot alkaloids act as alpha-adrenergic antagonists.
Indole Alkaloids
Group of alkaloids containing a benzylpyrrole group (derived from TRYPTOPHAN)
Pyrrolizidine Alkaloids
A group of ALKALOIDS, characterized by a nitrogen-containing necine, occurring mainly in plants of the BORAGINACEAE; COMPOSITAE; and LEGUMINOSAE plant families. They can be activated in the liver by hydrolysis of the ester and desaturation of the necine base to reactive electrophilic pyrrolic CYTOTOXINS.
Vinca Alkaloids
A group of indole-indoline dimers which are ALKALOIDS obtained from the VINCA genus of plants. They inhibit polymerization of TUBULIN into MICROTUBULES thus blocking spindle formation and arresting cells in METAPHASE. They are some of the most useful ANTINEOPLASTIC AGENTS.
Scopolamine Hydrobromide
An alkaloid from SOLANACEAE, especially DATURA and SCOPOLIA. Scopolamine and its quaternary derivatives act as antimuscarinics like ATROPINE, but may have more central nervous system effects. Among the many uses are as an anesthetic premedication, in URINARY INCONTINENCE, in MOTION SICKNESS, as an antispasmodic, and as a mydriatic and cycloplegic.
Solanum
A plant genus of the family SOLANACEAE. Members contain SOLANACEOUS ALKALOIDS. Some species in this genus are called deadly nightshade which is also a common name for ATROPA BELLADONNA.
Plant Roots
Berberine Alkaloids
A group of related plant alkaloids that contain the BERBERINE heterocyclic ring structure.
Dopamine Plasma Membrane Transport Proteins
Solanum melongena
A plant species of the genus SOLANUM, family SOLANACEAE. The fruit is a large, egg-shaped berry, varying in color from dark purple to red, yellowish, or white. The leaves are large and ovate. The flowers are pendant, violet, and two inches across.
Physalis
A plant genus of the family SOLANACEAE. Members contain physalin and withangulatin.
Benztropine
A centrally active muscarinic antagonist that has been used in the symptomatic treatment of PARKINSON DISEASE. Benztropine also inhibits the uptake of dopamine.
Capsicum
A plant genus of the family SOLANACEAE. The hot peppers yield CAPSAICIN, which activates VANILLOID RECEPTORS. Several varieties have sweet or pungent edible fruits that are used as vegetables when fresh and spices when the pods are dried.
Amaryllidaceae Alkaloids
Atropine
An alkaloid, originally from Atropa belladonna, but found in other plants, mainly SOLANACEAE. Hyoscyamine is the 3(S)-endo isomer of atropine.
Nortropanes
Noradrenergic and specific serotonergic antidepressants (NaSSAs), often referred to as "nortropanes," are a class of drugs that function by selectively binding to and partially blocking the α2-adrenergic receptors and 5-HT2 receptors, thereby increasing the concentration of norepinephrine and serotonin in the synaptic cleft, which helps alleviate symptoms of depression.
Aconitum
A plant genus of the family RANUNCULACEAE. Members contain a number of diterpenoid alkaloids including: aconitans, hypaconitine, ACONITINE, jesaconitine, ignavine, napelline, and mesaconitine. The common name of Wolfbane is similar to the common name for ARNICA.
