C17H21NO4 (303.1471)


Scopolamine, also known as hyoscine, is a tropane alkaloid drug obtained from plants of the family Solanaceae (nightshades), such as henbane or jimson weed (Datura species). It is part of the secondary metabolites of plants. Scopolamine is used criminally as a date rape drug and as an aid to robbery, the most common act being the clandestine drugging of a victims drink. It is preferred because it induces retrograde amnesia, or an inability to recall events prior to its administration. Victims of this crime are often admitted to a hospital in police custody, under the assumption that the patient is experiencing a psychotic episode. A telltale sign is a fever accompanied by a lack of sweat. An alkaloid from Solanaceae, especially Datura metel L. and Scopola carniolica. 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.

Cocaine

[1R-(exo,exo)]-3-(Benzoyloxy)-8-methyl-8-azabicyclo[3.2.1]octane-2-carboxylic acid, methyl ester

C17H21NO4 (303.1471)


Cocaine, also known as coke, is an alkaloid ester obtained from the leaves of the coca plant (PMID: 20857618). It is a weakly alkaline compound and can therefore combine with acidic compounds to form white salts or powders (which is how it is typically sold and consumed). Cocaine is a strong stimulant that is most frequently used as a recreational drug. It is the second most frequently used illegal drug globally, after cannabis. The stimulant and hunger suppression properties of cocaine and coca leaf extracts have been known for thousands of years by indigenous groups in central and South America. The coca leaf was, and still is, chewed almost universally by some indigenous communities. Cocaine acts by inhibiting the reuptake of serotonin, norepinephrine, and dopamine. This inhibition leads to a number of mental and physical effects that may include loss of contact with reality, an intense feeling of happiness, periods of agitation, along with a rapid heart rate, sweating, and dialated pupils. Cocaine is highly addictive due to its effect on the reward pathway in the brain (PMID: 22856655). Cocaine addiction occurs through overexpression of the FosB protein in the nucleus accumbens of the brain, which results in altered transcriptional regulation in neurons within the nucleus accumbens. Cocaine is harmful. Its use increases the risk of stroke, myocardial infarction, lung problems (in those who smoke it), blood infections, and sudden cardiac death. Medically, cocaine is infrequently used as a local anesthetic and vasoconstrictor to cause loss of feeling or numbness before certain medical procedures (e.g., biopsy, stitches, wound cleaning) (PMID: 28956316). Topical cocaine is occasionally used as a local numbing agent to help with painful procedures in the mouth or nose. Cocaine is now predominantly used for nasal and lacrimal duct surgery. It works quickly to numb certain areas of the body (e.g., nose, ear, or throat) about 1-2 minutes after application. Cocaine functions as an anesthesia by reversibly binding to and inactivating sodium channels, thereby inhibiting excitation of nerve endings or by blocking conduction in peripheral nerves. Cocaine and its major metabolites are only found in individuals that have used or taken this drug.

(2E)-4-Hydroxy-3-methylpent-2-enedioylcarnitine

3-[(4-carboxy-2-hydroxy-3-methylbut-3-enoyl)oxy]-4-(trimethylazaniumyl)butanoate

C13H21NO7 (303.1318)


(2E)-4-hydroxy-3-methylpent-2-enedioylcarnitine is an acylcarnitine. More specifically, it is an (2E)-4-hydroxy-3-methylpent-2-enedioic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. (2E)-4-hydroxy-3-methylpent-2-enedioylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine (2E)-4-hydroxy-3-methylpent-2-enedioylcarnitine is a member of the most abundant group of carnitines in the body, comprising more than 50\\% of all acylcarnitines quantified in tissues and biofluids (PMID: 31920980). Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. In particular (2E)-4-hydroxy-3-methylpent-2-enedioylcarnitine is elevated in the blood or plasma of individuals with 3-hydroxy-3-ethylglutarylCoA lyase deficiency (PMID: 32685354). Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].

Has no odor. pH (of 5\\% solution): 4-5.5. Slightly efflorescent in dry air. Bitter, acrid taste. (NTP, 1992) Scopolamine is a tropane alkaloid that is the (S)-tropic acid ester of 6beta,7beta-epoxy-1alphaH,5alphaH-tropan-3alpha-ol. It has a role as a muscarinic antagonist, an antiemetic, an adjuvant, a mydriatic agent, an antispasmodic drug, an anaesthesia adjuvant, an antidepressant and a metabolite. It is a propanoate ester, an epoxide, a tertiary amino compound and a tropane alkaloid. It is functionally related to a (S)-tropic acid. It is a conjugate base of a scopolamine(1+). Scopolamine is a tropane alkaloid isolated from members of the Solanaceae family of plants, similar to [atropine] and [hyoscyamine], all of which structurally mimic the natural neurotransmitter [acetylcholine]. Scopolamine was first synthesized in 1959, but to date, synthesis remains less efficient than extracting scopolamine from plants. As an acetylcholine analogue, scopolamine can antagonize muscarinic acetylcholine receptors (mAChRs) in the central nervous system and throughout the body, inducing several therapeutic and adverse effects related to alteration of parasympathetic nervous system and cholinergic signalling. Due to its dose-dependent adverse effects, scopolamine was the first drug to be offered commercially as a transdermal delivery system, Scopoderm TTS®, in 1981. As a result of its anticholinergic effects, scopolamine is being investigated for diverse therapeutic applications; currently, it is approved for the prevention of nausea and vomiting associated with motion sickness and surgical procedures. Scopolamine was first approved by the FDA on December 31, 1979, and is currently available as both oral tablets and a transdermal delivery system. Scopolamine is an Anticholinergic. The mechanism of action of scopolamine is as a Cholinergic Antagonist. Hyoscine is a natural product found in Duboisia leichhardtii, Duboisia myoporoides, and other organisms with data available. Scopolamine is a tropane alkaloid derived from plants of the nightshade family (Solanaceae), specifically Hyoscyamus niger and Atropa belladonna, with anticholinergic, antiemetic and antivertigo properties. Structurally similar to acetylcholine, scopolamine antagonizes acetylcholine activity mediated by muscarinic receptors located on structures innervated by postganglionic cholinergic nerves as well as on smooth muscles that respond to acetylcholine but lack cholinergic innervation. The agent is used to cause mydriasis, cycloplegia, to control the secretion of saliva and gastric acid, to slow gut motility, and prevent vomiting. 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.
