Epichatechin is one of the 4 catechin diastereoisomers. It can be isolated from a number of species of Palmae, as well as Dryas octopetala and guarana seeds. Epicatechin has been widely studied as a potential therapeutic compound in a wide variety of conditions including cancers, diabetes, heart conditions, and neurological conditions. Epicatechin is available as a natural health supplement and marketed for bodybuilding and the treatment of high blood pressure, high cholesterol, immune support, low testosterone, high blood sugar, and improved memory.

Menatetrenone (INN), also known as MK4, is a vitamin K compound used as a hemostatic agent, and also as adjunctive therapy for the pain of osteoporosis. MK4 is marketed for the osteoporosis indication in Japan by Eisai Co., under the trade name Glakay. Has several mechanism of actions: (1) Acceleration of osteogenesis. In human osteoblast cultures, calcification was accelerated by administration of menatetrenone at a concentration of 2.25 × 10-6 mol/L alone or when it was coadministered with 1,25(OH)2D3. The osteocalcin content in the cell layers was increased by coadministration with 1,25(OH)2D3. 2. Inhibition of bone resorption. In organ cultures of mouse calvaria, at concentrations of 3 × 10-6 to 3 × 10-5 mol/L, menatetrenone inhibited bone resorption induced by IL-1α, PGE2, PTH and 1,25(OH)2D3. In mouse bone marrow cell cultures, at concentrations of 3 × 10-6 to 1 × 10-5 mol/L, menatetrenone inhibited the induction of osteoclast release by 1,25(OH)2D3. 3. Effect on serum level of osteocalcin. Menatetrenone was administered to patients with osteoporosis at a dose of 45 mg/day for 2 years. Menatetrenone increased the serum level of osteocalcin and decreased the serum level of Glu-osteocalcin.

Berberine, an alkaloid isolated from Rhizoma Coptidis, is known to have a wide array of therapeutic effects including antimicrobial, antineoplastic, and hepatoprotective effects. It is found in several plants including European barberry, goldenseal, goldthread, Oregon grape, phellodendron, and tree tumeric. Berberine seems to slightly reduce blood sugar levels in people with diabetes. Berberine might lower blood pressure. Berberine is possibly safe for most adults for short-term use when taken by mouth or applied to the skin.

Sesamin is the most prominent lignan compound found in sesame seeds, one of the two highest sources of lignans in the human diet (the other being flax). Sesamin is catered to be a nutritional supplement that confers antioxidant and antiinflammatory effects (if touting its health properties) or possibly being an estrogen receptor modulator and fat burner (if targeting atheltes or persons wishing to lose weight). Sesamin has a few mechanisms, and when looking at it holistically it can be summed up as a fatty acid metabolism modifier. It appears to inhibit an enzyme known as delta-5-desaturase (Δ5-desaturase) which is a rate-limiting enzyme in fatty acid metabolism; inhibiting this enzyme results in lower levels of both eicosapentaenoic acid (EPA, one of the two fish oil fatty acids) as well as arachidonic acid, and this mechanism appears to be relevant following oral ingestion. The other main mechanism is inhibiting a process known as Tocopherol-ω-hydroxylation, which is the rate limiting step in the metabolism of Vitamin E; by inhibiting this enzyme, sesamin causes a relative increase of vitamin E in the body but particularly those of the gamma subset (γ-tocopherol and γ-tocotrienol) and this mechanism has also been confirmed to be active following oral ingestion. Sesamin is a potent and specific inhibitor of delta 5 desaturase in polyunsaturated fatty acid biosynthesis. Sesamin inhibits a particular CYP3A enzymes that is involved in vitamin E metabolism, where the enzyme initially ω-hydroxylates vitamin E (required step) and then the rest of vitamin E is subject to fat oxidation. By inhibiting this step, sesamin causes an increase in circulating and organ concentrations of vitamin E. Sesamin is thought to have PPARα activating potential in the liver, but it is uncertain how much practical relevance this has in humans due to this being a mechanism that differs between species.

Honokiol is a biphenolic natural product isolated from the bark and leaves of Magnolia plant spp. Honokiol possesses anti-carcinogenic, anti-inflammatory, anti-oxidative, anti-angiogenic as well as the inhibitory effect on malignant transformation of papillomas to carcinomas in vitro and in vivo animal models without any appreciable toxicity. Honokiol affects multiple signaling pathways, molecular and cellular targets including nuclear factor-κB (NF-κB), STAT3, epidermal growth factor receptor (EGFR), cell survival signaling, cell cycle, cyclooxygenase and other inflammatory mediators, etc. Honokiol can permeate the blood-brain barrier and the blood-cerebrospinal fluid to increase its bioavailability in neurological tissues. Diverse studies have provided evidence on the neuroprotective effect of honokiol in the central nervous system, due to its potent antioxidant activity, and amelioration of the excitotoxicity mainly related to the blockade of glutamate receptors and reduction in neuroinflammation. Honokiol can attenuate neurotoxicity exerted by abnormally aggregated Abeta in Alzheimer's disease. Honokiol is being developed by Huons as HL tablet for the treatment of alcoholic and non-alcoholic fatty liver.

Peoniflorin (PF) is the chief active component of paeonia, with diverse pharmacological actions and wide application. According to current study findings, PF can ameliorate the decline of memory and learning capacities in many dementia model animals, and have effect in protecting the cerebral ischemia injury, treating Parkinson's disease, reliving pain and improving neural synapse plasticity. Peoniflorin is an Adenosine A1 receptor activator with neuroprotective and antidepressant effects. Upregulates serotonergic systems in vivo. Blood brain barrier permeable. Preclinical studies show that peoniflorin is able to diminish pain, joint swelling, synovial hypertrophy, and the severity of bone erosion and cartilage degradation in experimental arthritis. In China, Korea, and Japan, a decoction of the dried root without bark of Paeonia lactiflora Pall. has been used in the treatment of rheumatoid arthritis, systemic lupus erythematosus, hepatitis, dysmenorrhea, muscle cramping and spasms, and fever for more than 1200 years. A water/ethanol extract of the root is now known as total glucosides of peony (TGP), which contains more than 15 components. Peoniflorin is the most abundant ingredient and accounts for the pharmacological effects observed with TGP in both in vitro and in vivo studies.

Aloe emodin is a hydroxyanthraquinone found in Aloe vera leaves. It plays an important role in the regulation of cell growth and death. It has been reported to promote the anti-cancer effects in various cancer cells by inducing apoptosis. Aloe emodin selectively inhibits human neuroectodermal tumor cell growth in tissue cultures and in animal models. It has significant antileukemic activity against the P-388 lymphocytic leukemia in mice. Anti-glioma action of Aloe emodin involves ERK-independent induction of both apoptosis and autophagy, as well as ERK inhibition-mediated differentiation of glioma cells. Aloe-emodin can not pass through the blood-brain barrier.

Jasmone is a natural organic compound extracted from the volatile portion of the oil from jasmine flowers. The natural extract contains only the cis form, while the synthetic material is often a mixture containing both forms, with the cis form predominating. Commercially it is used primarily in perfumes and cosmetics. Some studies on rodents had shown that cis-jasmine had a tranquillizing effect on the brain, possibly through the GABA-A receptors response.

Cupric nitrate (Copper(II) nitrate) is an inorganic compound that forms a blue crystalline solid. Copper(II) nitrate finds a variety of applications, the main one being its conversion to copper(II) oxide, which is used as catalyst for a variety of processes in organic chemistry. Its solutions are used in textiles and polishing agents for other metals. Copper nitrates are found in some pyrotechnics. It is often used in school laboratories to demonstrate chemical voltaic cell reactions. Strong oxidizing agent.
