Methylecgonine
Methylecgonine, also known as ecgonine methyl ester is a prominent tropane alkaloid found in coca leaves. It is metabolite of cocaine, and may be used as a precursor for it. It also occurs as minor alkaloid in roots of many ''Datura'' species such as ''Datura stramonium'' and '' Datura innoxia''. Biosynthesis It is the last step before cocaine is biosynthesized in coca plants with the help of BAHD acyltransferase. Animal study Animals study suggest that it has beneficial effect on cognition and protects against cocaine lethality. It showed inhibition of sodium channel Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell (biology), cell's cell membrane, membrane.

Cocaine
Cocaine is a tropane alkaloid and central nervous system stimulant, derived primarily from the leaves of two South American coca plants, ''Erythroxylum coca'' and ''Erythroxylum novogranatense, E. novogranatense'', which are cultivated almost exclusively in the Andes. Indigenous peoples of South America, Indigenous South Americans have traditionally used coca leaves for over a thousand years. Notably, there is no evidence that habitual coca leaf use causes addiction or withdrawal, unlike cocaine. Medically, cocaine is rarely employed, mainly as a topical medication under controlled settings, due to its high abuse potential, adverse effects, and expensive cost. Despite this, recreational drug use, recreational use is widespread, driven by its euphoric and aphrodisiac properties. Levamisole induced necrosis syndrome (LINES)-a complication of the common cocaine Lacing (drugs), cutting agent levamisole-and prenatal cocaine exposure is particularly harmful. Street cocaine is ...

Datura Stramonium
''Datura stramonium'', known by the common names thornapple, jimsonweed (jimson weed), or devil's trumpet, is a poisonous flowering plant in the ''Datureae, Daturae'' Tribe (botany), tribe of the nightshade family Solanaceae. Its likely origin was in Central America, and it has been introduced in many world regions. It is an aggressive invasive species, invasive weed in temperate climates and tropical climates across the world. ''D. stramonium'' has frequently been employed in traditional medicine to treat a variety of ailments. It has also been used as a hallucinogen (of the anticholinergic/antimuscarinic, deliriant type), taken entheogenically to cause intense, sacred or occult visions.Schultes, Richard Evans; Albert Hofmann (1979).

Ecgonine
Ecgonine (tropane derivative) is a tropane alkaloid found naturally in coca leaves. It has a close structural relation to cocaine: it is both a metabolite and a precursor, and as such, it is a controlled substance in many jurisdictions, as are some substances which can be used as precursors to ecgonine itself. Structurally, ecgonine is a cycloheptane derivative with a nitrogen bridge. It is obtained by hydrolysis of cocaine with acids or alkalis, and crystallizes with one molecule of water, the crystals melting at 198–199 °C. It is levorotary, and on warming with alkalis gives iso-ecgonine, which is dextrorotary. It is a tertiary base, and has the properties of an acid and an alcohol. It is the carboxylic acid corresponding to tropine, for it yields the same products on oxidation, and by treatment with phosphorus pentachloride is converted into anhydroecgonine, C9H13NO2, which, when heated to 280 °C with hydrochloric acid, eliminates carbon dioxide Carbo ...

Tropane Alkaloid
Tropane alkaloids are a class of bicyclic .2.1alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae. Certain tropane alkaloids such as cocaine and scopolamine are notorious for their psychoactive effects, related usage and cultural associations. Particular tropane alkaloids such as these have pharmacological properties and can act as anticholinergics or stimulants. Classification Anticholinergics Anticholinergic drugs and deliriants: * Atropine, racemic hyoscyamine, from the deadly nightshade (''Atropa belladonna'') * Hyoscyamine, the ''levo''-isomer of atropine, from henbane (''Hyoscyamus niger''), mandrake ('' Mandragora officinarum'') and the sorcerers' tree ('' Latua pubiflora''). * Scopolamine, from henbane and ''Datura'' species (Jimson weed) All three acetylcholine-inhibiting chemicals can also be found in the leaves, stems, and flowers in varyi ...

Erythroxylum Coca
''Erythroxylum coca'' is one of two species of cultivated coca. Description The coca plant resembles a blackthorn bush, and grows to a height of . The branches are straight, and the leaves, which have a green tint, are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the underside of the leaf. Coca plants are mainly found in Colombia. The flowers are small, and disposed in little clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries. Unlike ''Erythroxylum novogranatense'', ''Erythroxylum coca'' requires very acidic soil conditions. Soil acidity and water acidity need to be below pH 5.5, with the optimal value being pH 3.5, similar to that of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Datura
''Datura'' is a genus of nine species of highly poisonous, Vespertine (biology), vespertine-flowering plants belonging to the nightshade family (Solanaceae). They are commonly known as thornapples or jimsonweeds, but are also known as devil's trumpets or mad apple (not to be confused with angel's trumpets, which are placed in the closely related genus ''Brugmansia''). Other English common names include moonflower, devil's weed, and hell's bells. All species of ''Datura'' are extremely poisonous and Psychoactive plant, psychoactive, especially their seeds and flowers, which can cause respiratory depression, arrhythmias, fever, delirium, hallucinations, Toxidrome#Anticholinergic, anticholinergic toxidrome, psychosis, and death if taken internally. The name ''Datura'' originates from the Hindi and Sanskrit words for “thorn-apple,” with historical and cultural significance in Ayurveda and Hinduism, while the English term “Jimsonweed” derives from its prevalence in Jamestown, ...

Datura Innoxia
''Datura innoxia'' (often spelled ''inoxia''), known as pricklyburr, recurved thorn-apple, downy thorn-apple, Indian-apple, lovache, moonflower, nacazcul, toloatzin, toloaxihuitl, tolguache or toloache, is a species of flowering plant in the family Solanaceae. It is more rarely called sacred datura, a common name which is applied more often to the closely related ''Datura wrightii''. It is native to the Southwestern United States, Central and South America, and introduced in Africa, Asia, Australia and Europe. The scientific name is often cited as ''D. innoxia''. When English botanist Philip Miller first described the species in 1768, he misspelled the Latin word ''innoxia'' (inoffensive) when naming it ''D. inoxia''. The name ''Datura meteloides'' was for some time erroneously applied to some members of the species, but that name has now been abandoned. Description ''Datura innoxia'' is a tuberous-rooted subshrub that typically reaches a height of 0.6 to 1.5 metres. Its stems ...

BAHD Acyltransferase
{{technical, date=September 2015 General Information The BAHD acyltransferases are a super family of enzymes found primarily in plants, algae and bacteria. They are CoA-dependent enzymes that transfer acylated moieties (RC(O)R’) of an acyl-activated CoA thioester donor to an acceptor molecule (D’Auria, 2006). Members of this enzyme family typically share two conserved amino acid motifs. The first motif, or string of consecutive amino acids, is HXXXD (Histidine, Any, Any, Any, Aspartic acid) and it is typically found in the central region of the protein. The Histidine in this motif has also been shown to act as a catalytic residue in many BAHD enzymes. The second conserved motif is DFGWG (Aspartic acid, Phenylalanine, Glycine, Tryptophan, Glycine) and it is typically found near the carboxyl terminus of the protein and is thought to participate in CoA binding (D'Auria, 2006). Additionally, further information such as currently discovered structures, sequences and gene architectu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Physiology
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration. Plant physiology interacts with the fields of plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. Aims The field of plant physiology includes the study of all the internal activities of plants—those chemical and physical processes associated with life as they occur in plants. This includes study at many levels of scale of size and time. At the smallest scale are molecular interactions of photosynthesis and internal ...

Cocaine Intoxication
Cocaine intoxication refers to the subjective, desired and adverse effects of cocaine on the mind and behavior of users. Both self-induced and involuntary cocaine intoxication have medical and legal implications (even in absence of relevant adverse effects). Adverse effects can develop over time due to repeated use and so become chronic conditions. However, even a one-time intake of the substance can result in severe acute intoxication. Recurrent cocaine use and dependence to the drug inevitably leads to the reduction of the desired effects perceived by the users, while the occurrence of adverse effects of intoxication increase. The last can sometimes be completely reversed without bearing consequences but they can also potentially kill the users (e.g., in cases of untreated or non-manageable overdoses). Signs and symptoms Cocaine increases alertness, feelings of well-being, euphoria, energy, sociability, and sexuality. The former are some of the desired effects of cocaine intox ...
