Protopanaxadiol (PPD) is an organic compound that is an aglycone of ginsenosides, a group of steroid glycosides. It is a dammarane-type tetracyclic terpene sapogenin found in ginseng (Panax ginseng) and in notoginseng (Panax pseudoginseng). [1] [2]
The health effect of protopanaxadiol inside the human body is still unclear. One study suggests it has rapid, non-genomic effects on endothelial cells, binding to the glucocorticoid and oestrogen beta receptors. The study also showed an increase in intracellular calcium ion concentration. [3]
Shanghai Innovative Research Center of Traditional Chinese Medicine (SIRC-TCM) is trying to develop an antidepressant based on this substance under the brand name Yoxintine. The drug has finished phase II trials as of May 2023. [4] Results were published in November 2024. [5]
A pharmacokinetic study done on phase IIa human volunteers reports the relationship between oral dose and blood plasma concentration, but no data is given for oral bioavailbility, half life, or volume of distribution. [6] In rats, the oral bioavailbility is about 48% and the half-life is 6.25 hours when given as an extract containing both PPD and PPT. When given alone, reported bioavailbility values are lower, at 20.7–36.8%. [7]
Hyperforin is a phytochemical produced by some of the members of the plant genus Hypericum, notably Hypericum perforatum. Hyperforin may be involved in the pharmacological effects of St. John's wort, specifically in its antidepressant effects.
Mesembrine is an alkaloid primarily derived from the plant Sceletium tortuosum, commonly known as kanna. This compound is noted for its psychoactive properties, particularly as a serotonin reuptake inhibitor, which contributes to its potential use in treating mood disorders and anxiety. Mesembrine has garnered interest in both traditional medicine and modern pharmacology, where it is explored for its effects on enhancing mood and cognitive function. The plant itself has a long history of use by indigenous peoples in southern Africa, who utilized it for its mood-enhancing and stress-relieving effects, often consuming it in various forms such as teas or chews.
Panax notoginseng is a species of the genus Panax, and it is commonly referred to in English as Chinese ginseng or notoginseng. In Chinese it is called tiánqī, tienchi ginseng, sānqī or sanchi, three-seven root, and mountain plant. P. notoginseng belongs to the same scientific genus as Panax ginseng. In Latin, the word panax means "cure-all", and the family of ginseng plants is one of the best-known herbs.
Ginsenosides or panaxosides are a class of natural product steroid glycosides and triterpene saponins. Compounds in this family are found almost exclusively in the plant genus Panax (ginseng), which has a long history of use in traditional medicine that has led to the study of pharmacological effects of ginseng compounds. As a class, ginsenosides exhibit a large variety of subtle and difficult-to-characterize biological effects when studied in isolation.
Shō-saiko-tō (小柴胡湯), also known as minor bupuleurum formula and xiǎocháihútāng (XCHT), is a herbal supplement, believed to enhance liver health. Sho-Saiko-To is a widely used prescription drug in China and is a listed formula in China and Japan as a Kampo medicine. There are currently ongoing clinical trials for Sho-Saiko-To at University of California, San Diego and Memorial Sloan-Kettering Cancer Center. The active ingredients of sho-saiko-to discovered so far include baicalin, baicalein, glycyrrhizin, saikosaponins, ginsenosides, wogonin, and gingerol.
Dauricine is a plant metabolite, chemically classified as a phenol, an aromatic ether, and an isoquinoline alkaloid. It has been isolated from the Asian vine Menispermum dauricum, commonly known as Asian moonseed, and the North American vine Menispermum canadense, commonly known as Canadian moonseed. Scientists Tetsuji Kametani and Keiichiro Fukumoto of Japan are credited with being the first to synthesize dauricine in 1964, using both the Arndt-Eistert reaction and Bischler-Napieralski reaction to do so. Dauricine has been studied in vitro for its potential to inhibit cancer cell growth and to block cardiac transmembrane Na+, K+, and Ca2+ ion currents.
Osladine is a high-intensity sweetener isolated from the rhizome of Polypodium vulgare. It is a saponin, sapogenin steroid glycoside, 500 times sweeter than sucrose.
Cangrelor, sold under the brand name Kengreal among others, is a P2Y12 inhibitor FDA approved as of June 2015 as an antiplatelet drug for intravenous application. Some P2Y12 inhibitors are used clinically as effective inhibitors of adenosine diphosphate-mediated platelet activation and aggregation. Unlike clopidogrel (Plavix), which is a prodrug, cangrelor is an active drug not requiring metabolic conversion.
Panaxatriol is an organic compound that is an aglycone of ginsenosides, a group of steroid glycosides. It is a dammarane-type tetracyclic triterpene sapogenin found in ginseng and in notoginseng. It is formed by the dehydration of protopanaxatriol.
Protopanaxatriol (PPT) is an organic compound that is an aglycone of ginsenosides, a group of steroid glycosides. It is a dammarane-type tetracyclic triterpene sapogenins found in ginseng and in notoginseng.
Procyanidin A1 is an A type proanthocyanidin dimer.
Dapoxetine, marketed as Priligy, among others, is a selective serotonin reuptake inhibitor (SSRI) used for the treatment of premature ejaculation (PE) in men 18–64 years old. Dapoxetine works by inhibiting the serotonin transporter, increasing serotonin's action at the postsynaptic cleft, and as a consequence promoting ejaculatory delay. As a member of the selective serotonin reuptake inhibitor (SSRI) family, dapoxetine was initially created as an antidepressant. However, unlike other SSRIs, dapoxetine is absorbed and eliminated rapidly in the body. Its fast-acting property makes it suitable for the treatment of PE, but not as an antidepressant.
American ginseng is a species of flowering plant in the ivy family Araliaceae. It is native to eastern North America and has been introduced into China. The specific epithet quinquefolius means "five-leaved", which refers to the typical number of leaflets per leaf. It is one of a group of taxa known as "ginseng".
ALTO-100, previously known as NSI-189, is a drug described as a hippocampal neurogenesis stimulant and indirect brain-derived neurotrophic factor (BDNF) modulator which is under development for the treatment of major depressive disorder (MDD), bipolar depression, and post-traumatic stress disorder (PTSD). There has also been interest in ALTO-100 for possible treatment of cognitive impairment and neurodegeneration. It is taken by mouth.
Pseudoginsenoside F11 is a chemical natural product found in American ginseng but not in Asian ginseng, although it has similar properties to the Asian ginseng compound ginsenoside Rf. The molecule is a triterpenoid saponin member of the dammarane family and contains a four-ring rigid skeleton. Compounds in the ginsenoside family are found almost exclusively in plants of the genus Panax. A wide variety of difficult-to-characterize in vitro effects have been reported for the compounds in isolation. Pseudoginsenoside F11 and its derivatives are sometimes referred to as having an ocotillol-type skeleton structure.
Vamorolone, sold under the brand name Agamree, is a synthetic corticosteroid, which is used for the treatment of Duchenne muscular dystrophy. It is taken by mouth. It is a dual atypical glucocorticoid and antimineralocorticoid.
Dagrocorat is a nonsteroidal but steroid-like selective glucocorticoid receptor modulator (SGRM) which was under development for the treatment of rheumatoid arthritis but was never marketed. It is described as a partial agonist and "dissociable" agonist of the glucocorticoid receptor. The drug reached phase I clinical trials prior to the discontinuation of its development. The C2α dihydrogen phosphate ester of dagrocorat, fosdagrocorat, was also under investigation, but its development was terminated as well.
Fosdagrocorat is a nonsteroidal but steroid-like selective glucocorticoid receptor modulator (SGRM) which was under development for the treatment of rheumatoid arthritis but was never marketed. It is the C2 dihydrogen phosphate ester of dagrocorat, and acts as a prodrug of dagrocorat with improved pharmacokinetics. The drug reached phase II clinical trials prior to the discontinuation of its development.
Dammarenes are derivatives of dammaranes that have a double bond.
