Hyoscyamine
(S)-atropine is an atropine with a 2S-configuration. It is functionally related to a (S)-tropic acid. It is a conjugate base of a (S)-atropinium. Hyoscyamine is a tropane alkaloid and the levo-isomer of [atropine]. It is commonly extracted from plants in the Solanaceae or nightshade family. Research into the action of hyoscyamine in published literature dates back to 1826. Hyoscyamine is used for a wide variety of treatments and therapeutics due to its antimuscarinic properties. Although hyoscyamine is marketed in the United States, it is not FDA approved. Hyoscyamine as a natural plant alkaloid derivative and anticholinergic that is used to treat mild to moderate nausea, motion sickness, hyperactive bladder and allergic rhinitis. Hyoscyamine has not been implicated in causing liver enzyme elevations or clinically apparent acute liver injury. L-Hyoscyamine is a natural product found in Datura ferox, Crenidium spinescens, and other organisms with data available. Hyoscyamine is a belladonna alkaloid derivative and the levorotatory form of racemic atropine isolated from the plants Hyoscyamus niger or Atropa belladonna, which exhibits anticholinergic activity. Hyoscyamine functions as a non-selective, competitive antagonist of muscarinic receptors, thereby inhibiting the parasympathetic activities of acetylcholine on the salivary, bronchial, and sweat glands, as well as the eye, heart, bladder, and gastrointestinal tract. These inhibitory effects cause a decrease in saliva, bronchial mucus, gastric juices, and sweat. Furthermore, its inhibitory action on smooth muscle prevents bladder contraction and decreases gastrointestinal motility. The 3(S)-endo isomer of atropine. Hyoscyamine is a chemical compound, a tropane alkaloid it is the levo-isomer to atropine. It is a secondary metabolite of some plants, particularly henbane (Hyoscamus niger.).

3-Methylglutarylcarnitine
3-Methylglutarylcarnitine is an acylcarnitine. More specifically, it is an methylglutaric 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. 3-Methylglutarylcarnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine 3-methylglutarylcarnitine is somewhat less abundant than short-chain acylcarnitines. These are formed either through esterification with L-carnitine or through the peroxisomal metabolism of longer chain acylcarnitines (PMID: 30540494). Many medium-chain acylcarnitines can serve as useful markers for inherited disorders of fatty acid metabolism. In particular 3-methylglutarylcarnitine is elevated in the blood or plasma of individuals with psoriasis (PMID: 33391503), CVD (PMID: 32376321), Norman-Roberts syndrome (PMID: 15083694), type 2 diabetes Mellitus (PMID: 20111019, PMID: 19369366, PMID: 29436377), carnitine palmitoyl-trasferase 2 deficiency (PMID: 9657346), Familial Mediterranean Fever (PMID: 29900937), multiple acyl coenzyme A dehydrogenase Deficiency (PMID: 30510944), CVD in type 2 diabetes Mellitus (PMID: 32431666), and gestational diabetes mellitus (PMID: 29436377). It is also decreased in the blood or plasma of individuals with Celiac disease (PMID: 16425363). 3-Methylglutarylcarnitine is elevated in the urine of individuals with medium-chain acyl-CoA dehydrogenase deficiency (PMID: 1635814, PMID: 2246856). 3-Methylglutarylcarnitine is a diagnostic metabolite of 3-hydroxy-3-methylglutaryl-coenzyme A lyase deficiency. It is also identified in the urine of patients with Reye-like syndrome (PMID: 3958190 , 10927963 ). Carnitine octanoyltransferase (CrOT, EC:2.3.1.137) is responsible for the synthesis of all medium-chain (MCAC, C5-C12) and medium-length branched-chain acylcarnitines in peroxisomes (PMID: 10486279). 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.

As a medium-chain acylcarnitine 6-hydroxyheptanoylcarnitine is somewhat less abundant than short-chain acylcarnitines. These are formed either through esterification with L-carnitine or through the peroxisomal metabolism of longer chain acylcarnitines (PMID: 30540494). Many medium-chain acylcarnitines can serve as useful markers for inherited disorders of fatty acid metabolism. Carnitine octanoyltransferase (CrOT, EC:2.3.1.137) is responsible for the synthesis of all medium-chain (MCAC, C5-C12) and medium-length branched-chain acylcarnitines in peroxisomes (PMID: 10486279). 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].
4-Ethoxy-4-oxobutanoylcarnitine
4-Ethoxy-4-oxobutanoylcarnitine is an acylcarnitine. More specifically, it is an 4-ethoxy-4-oxobutanoic 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.

(+)-Hyoscyamine
Atropine, a naturally occurring belladonna alkaloid, is a racemic mixture of equal parts of d- and l-hyoscyamine, whose activity is due almost entirely to the levo isomer of the drug. Atropine is commonly classified as an anticholinergic or antiparasympathetic (parasympatholytic) drug. More precisely, however, it is termed an antimuscarinic agent since it antagonizes the muscarine-like actions of acetylcholine and other choline esters. Adequate doses of atropine abolish various types of reflex vagal cardiac slowing or asystole. The drug also prevents or abolishes bradycardia or asystole produced by injection of choline esters, anticholinesterase agents or other parasympathomimetic drugs, and cardiac arrest produced by stimulation of the vagus. Atropine may also lessen the degree of partial heart block when vagal activity is an etiologic factor. Atropine in clinical doses counteracts the peripheral dilatation and abrupt decrease in blood pressure produced by choline esters. However, when given by itself, atropine does not exert a striking or uniform effect on blood vessels or blood pressure. Atropine is found in burdock. Atropine (Tropine tropate) is a competitive muscarinic acetylcholine receptor (mAChR) antagonist with IC50 values of 0.39 and 0.71 nM for Human mAChR M4 and Chicken mAChR M4, respectively. Atropine inhibits ACh-induced relaxations in human pulmonary veins. Atropine can be used for research of anti-myopia and bradycardia[1][2][3][4].

Atropine
Atropine is a racemate composed of equimolar concentrations of (S)- and (R)-atropine. It is obtained from deadly nightshade (Atropa belladonna) and other plants of the family Solanaceae. It has a role as a muscarinic antagonist, an anaesthesia adjuvant, an anti-arrhythmia drug, a mydriatic agent, a parasympatholytic, a bronchodilator agent, a plant metabolite, an antidote to sarin poisoning and a oneirogen. It contains a (S)-atropine and a (R)-atropine. Atropine is an alkaloid originally synthesized from Atropa belladonna. It is a racemic mixture of d-and l-hyoscyamine, of which only l-hyoscyamine is pharmacologically active. Atropine is generally available as a sulfate salt and can be administered by intravenous, subcutaneous, intramuscular, intraosseous, endotracheal and ophthalmic methods. Oral atropine is only available in combination products. Atropine is a competitive, reversible antagonist of muscarinic receptors that blocks the effects of acetylcholine and other choline esters. It has a variety of therapeutic applications, including pupil dilation and the treatment of anticholinergic poisoning and symptomatic bradycardia in the absence of reversible causes. Atropine is a relatively inexpensive drug and is included in the World Health Organization List of Essential Medicines. Atropine is an Anticholinergic and Cholinergic Muscarinic Antagonist. The mechanism of action of atropine is as a Cholinergic Antagonist and Cholinergic Muscarinic Antagonist. Hyoscyamine as a natural plant alkaloid derivative and anticholinergic that is used to treat mild to moderate nausea, motion sickness, hyperactive bladder and allergic rhinitis.
