Tabernaemontana Grandiflora
''Tabernaemontana'' is a genus of flowering plants in the family Apocynaceae. It has a pan-tropical distribution, found in Asia, Africa, Australia, North America, South America, and a wide assortment of oceanic islands. These plants are evergreen shrubs and small trees growing to 1–15 m tall. The leaves are opposite, 3–25 cm long, with milky sap; hence it is one of the diverse plant genera commonly called "milkwood". The flowers are fragrant, white, 1–5 cm in diameter. The cultivar '' T. divaricata'' cv. 'Plena', with doubled-petaled flowers, is a popular houseplant. Some members of the genus ''Tabernaemontana'' are used as additives to some versions of the psychedelic drink ayahuasca; the genus is known to contain ibogaine (e.g. in bëcchëte, ''T. undulata''), conolidine (present in minor concentration in ''T. divaricata'') and voacangine ('' T. alba'', '' T. arborea'', '' T. africana''). Because of presence of coronaridine and voacangine in Mexican ''Tabernae ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tabernaemontana Divaricata
''Tabernaemontana divaricata'', commonly called pinwheel flower, crape jasmine, East India rosebay, and Nero's crown, is an evergreen shrub or small tree native to South Asia, Southeast Asia and China. In zones where it is not hardy it is grown as a house/glasshouse plant for its attractive flowers and foliage. The stem exudes a milky latex when broken, whence the name milk flower. Description The plant generally grows to a height of and is dichotomously branched. The large shiny leaves are deep green and about in length and in width. The waxy blossoms are found in small clusters on the stem tips. The (single) flowers have the characteristic 'pinwheel' shape also seen in other genera in the family Apocynaceae such as ''Vinca'' and ''Nerium''. Both single and double-flowered forms are cultivated, the flowers of both forms being white. The plant blooms in spring but flowers appear sporadically all year. The flowers have a pleasing fragrance. More than 66 alkaloids are found in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ibogaine
Ibogaine is a naturally occurring psychoactive substance found in plants in the family Apocynaceae such as ''Tabernanthe iboga'', ''Voacanga africana'', and ''Tabernaemontana undulata''. It is a psychedelic with dissociative properties. Preliminary research indicates that it may help counter drug addiction. Its use has been associated with serious side effects and death. Between the years 1990 and 2008, a total of 19 fatalities temporally associated with the ingestion of ibogaine were reported, from which six subjects died of acute heart failure or cardiopulmonary arrest. The total number of subjects who have used it without major side effects during this period remains unknown. It is used as an alternative medicine treatment for drug addiction in some countries. Its prohibition in other countries has slowed scientific research. Ibogaine is also used to facilitate psychological introspection and spiritual exploration. Various derivatives of ibogaine designed to lack psychedel ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a tel ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dementia
Dementia is a disorder which manifests as a set of related symptoms, which usually surfaces when the brain is damaged by injury or disease. The symptoms involve progressive impairments in memory, thinking, and behavior, which negatively affects a person's ability to function and carry out everyday activities. Aside from memory impairment and a disruption in thought patterns, the most common symptoms include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Consciousness is not affected. Dementia ultimately has a significant effect on the individual, caregivers, and on social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning, and a greater cognitive decline than what is caused by normal aging. Several diseases and injuries to the brain, such as a stroke, can give rise to dementia. However, th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anxiolytic
An anxiolytic (; also antipanic or antianxiety agent) is a medication or other intervention that reduces anxiety. This effect is in contrast to anxiogenic agents which increase anxiety. Anxiolytic medications are used for the treatment of anxiety disorders and their related psychological and physical symptoms. Nature of anxiety Anxiety is a naturally-occurring emotion and an innate response of the body to the environmental stimuli. Mild to moderate anxiety would increase level of performance. However, when anxiety levels exceed the tolerability of a person, anxiety disorders may occur. People with anxiety disorders can exhibit fear responses such as defensive behaviors, high levels of alertness and negative emotions, without external stimuli which induce anxiety within an individual. Those with anxiety disorders are also often found to have concurrent psychological disorders, most commonly depression. Anxiety disorders are divided into 6 types in clinical recognition. They are ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tabernaemontana Sananho
''Tabernaemontana sananho'' is a tropical tree species in the family Apocynaceae known as lobo sanango. Lobo sanango grows in the Amazon Basin of northern South America. Chemical composition The plant is reported to contain coronaridine, 3-hydroxycoronaridine, (-)-heyneanine, (-)-ibogamine and voacangine. Traditional use In Amazonian traditional medicine, preparations of the leaves, pulp, bark, and latex are either applied topically or taken internally to treat various conditions. Extracts from the tree are antiinflammatory and effective against the protozoan ''Leishmania''. In Peru, this tree is sometimes known by the Spanish–Quechua name lobo sanango ("wolf plant") or simply as sanango. Throughout the Amazon the species has numerous other aliases in several languages. The Secoya people of Ecuador call this plant and put the sticky liquid from the fruit into dogs' noses so they can "smell far in hunting." They also eat the fruit of baĩ su'u.

Chemistry & Biodiversity
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence a ...

Voacangine
Voacangine (12-methoxyibogamine-18-carboxylic acid methyl ester) is an alkaloid found predominantly in the root bark of the ''Voacanga africana'' tree, as well as in other plants such as ''Tabernanthe iboga'', ''Tabernaemontana africana'', ''Trachelospermum jasminoides'', ''Tabernaemontana divaricata'' and ''Ervatamia yunnanensis''. It is an iboga alkaloid which commonly serves as a precursor for the semi-synthesis of ibogaine. It has been demonstrated in animals to have similar anti-addictive properties to ibogaine itself. It also potentiates the effects of barbiturates. Under UV-A and UV-B light its crystals fluoresce blue-green, and it is soluble in ethanol. Pharmacology Pharmacodynamics Voacangine exhibits AChE inhibitory activity. Docking simulation reveals that it has inhibitory effect on VEGF2 kinase and reduces angiogenesis. Like ibogaine, its a potent HERG blocker in vitro. It also acts as antagonist to TRPM8 and TRPV1 receptor but agonist of TRPA1. Pharmacokinetics The a ...

Coronaridine
Coronaridine, also known as 18-carbomethoxyibogamine, is an alkaloid found in ''Tabernanthe iboga'' and related species, including ''Tabernaemontana divaricata'' for which (under the now obsolete synonym ''Ervatamia coronaria'') it was named. Like ibogaine, (''R'')-coronaridine and (''S'')-coronaridine can decrease intake of cocaine and morphine intake in animals and it may have muscle relaxant and hypotensive activity. Chemistry Congeners Coronaridine congers are important in drug discovery and development due to multiple actions on different targets. They have ability to inhibit Cav2.2 channel, modulate and inhibit subunits of nAChr selectively such as α9α10, α3β4 and potentiate GABAA activity. Pharmacology Coronaridine has been reported to bind to an assortment of molecular sites, including: μ-opioid (Ki = 2.0 μM), δ-opioid (Ki = 8.1 μM), and κ-opioid receptors (Ki = 4.3 μM), NMDA receptor (Ki = 6.24 μM) (as an antagonist), and nAChRs (as an antagonist).
