alpha-Allocryptopine
Alpha-allocryptopine, also known as alpha-fagarine or beta-homochelidonine, is a member of the class of compounds known as protopine alkaloids. Protopine alkaloids are alkaloids with a structure based on a tricyclic protopine formed by oxidative ring fission of protoberberine N-metho salts. Alpha-allocryptopine is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Alpha-allocryptopine can be found in barley, which makes alpha-allocryptopine a potential biomarker for the consumption of this food product. Allocryptopine is a dibenzazecine alkaloid, an organic heterotetracyclic compound, a tertiary amino compound, a cyclic ketone, a cyclic acetal and an aromatic ether. Allocryptopine is a natural product found in Zanthoxylum beecheyanum, Berberis integerrima, and other organisms with data available. See also: Sanguinaria canadensis root (part of). KEIO_ID A137; [MS2] KO008812 KEIO_ID A137; [MS3] KO008813 KEIO_ID A137 Allocryptopine, a derivative of tetrahydropalmatine, is extracted from Macleaya cordata (Thunb.) Pers. Papaveraceae. Allocryptopine has antiarrhythmic effects and potently blocks human ether-a-go-go related gene (hERG) current[1][2].

7-Dehydrodesmosterol
7-dehydrodesmosterol, also known as cholesta-5,7,24-trien-3beta-ol or 24-dehydroprovitamin d3, belongs to cholesterols and derivatives class of compounds. Those are compounds containing a 3-hydroxylated cholestane core. Thus, 7-dehydrodesmosterol is considered to be a sterol lipid molecule. 7-dehydrodesmosterol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 7-dehydrodesmosterol can be found in a number of food items such as nectarine, orange bell pepper, cinnamon, and carrot, which makes 7-dehydrodesmosterol a potential biomarker for the consumption of these food products. In humans, 7-dehydrodesmosterol is involved in several metabolic pathways, some of which include atorvastatin action pathway, simvastatin action pathway, pamidronate action pathway, and steroid biosynthesis. 7-dehydrodesmosterol is also involved in several metabolic disorders, some of which include mevalonic aciduria, wolman disease, chondrodysplasia punctata II, X linked dominant (CDPX2), and hyper-igd syndrome. 7-Dehydrodesmosterol is a sterol intermediate in the biosynthesis of steroids. 7-Dehydrodesmosterol is a substrate of the enzyme 24-dehydrocholesterol reductase (EC:1.3.1.72), an important enzyme in the biosynthesis of Cholesterol. Cholesterol is synthesized from either Lathosterol, 7-Dehydrocholesterol, Desmosterol or Cholestenol by the enzyme 3beta-hydroxysterol delta7 reductase (EC 1.3.1.21, Dhcr7). The Smith-Lemli-Opitz syndrome (SLOS, OMIM 270400) is caused by a genetic defect in cholesterol biosynthesis; mutations in the enzyme 3beta-hydroxysterol delta7 reductase lead to a failure of cholesterol synthesis, with an accumulation of precursor sterols, such as 7-Dehydrodesmosterol. SLOS results in craniofacial, limb as well as major organ defects, including the brain. In individuals with this syndrome, mental retardation, as well as other CNS dysfunction, is almost 100\\% prevalent. (PMID: 15862627, 17197219).
Tetrahydrodeoxycorticosterone
The neurosteroid allotetrahydrodeoxycorticosterone (THDOC) is an allosteric modulator of the GABA(A) receptor. Although the role of THDOC within the brain is undefined, recent studies indicate that stress induces THDOC to levels that can activate GABA(A) receptors. These results might have significant implications for human stress-sensitive conditions such as epilepsy, post-traumatic stress disorder and depression.
