Methylinositol is a natural product in the family of inositols. It is found in many foods as well as pine tree bark. Methylinositol is found naturally in many foods and is commercially available as an approved food supplement. Methylinositol can mediate insulin action to improve glycemic control and insulin sensitivity in patients with type 2 diabetes mellitus, especially in patients with insulin resistance. It plays a positive role in regulating insulin-mediated glucose uptake in the liver through translocation and activation of the PI3K/Akt signaling pathway. The compound also modulates gamma-secretase to reduce A-betta production while sparing cleavage of the gamma-secretase substrate Notch. Methylinositol improves cognitive function and memory deficits in preclinical models of Alzheimer's disease (AD) neuropathology. Methylinositol was will tolerated in the population of AD subjects of varying age and severity. No serious adverse effects were detected in clinical trials. Many plant-derived compounds have excellent therapeutic potential against various human ailments. It was shown, that methylinositol mitigates tumor growth by modulating interleukins and hormones and induces apoptosis in rat breast carcinogenesis through inhibition of NF-κB.

Madecassoside is a triterpenoid compound found in Centella asiatica (Gotu kola), a medicinal herb used in traditional Chinese medicine (TCM), Ayurvedic medicine, and traditional African medicine. Madecassoside has a wide range of reported biological activities including, anti-inflammatory, wound healing, and anti-oxidant activities. It has been reported to suppress LPS-induced TNF-alpha production via inhibition of ERK, p38, and NF-kappaB activity. Madecassoside, a triterpenoid derivative isolated from Centella asiatica, exhibits anti-inflammatory and antioxidant activities. Madecassoside significantly reduced brain infarct area, resolved neurological deficit, and ameliorated neuronal apoptosis. It also significantly reduced the levels of malondialdehyde and nitric oxide, and augmented the antioxidant activity in rats subjected to cerebral I/R. Moreover, the levels of pro-inflammatory cytokines and NF-κB p65 significantly reduced after madecassoside treatment. Madecassoside is neuroprotective and may be useful in reducing the damage caused by stroke. Madecassoside has being shown to inhibits melanin synthesis by blocking ultraviolet-induced inflammation.

Idebenone is a synthetic short-chain benzoquinone and a substrate for the enzyme NAD(P)H:quinone oxidoreductase (NQO1) capable of stimulating mitochondrial electron transport and supplementing cellular energy levels. Idebenone was initially developed by Takeda Pharmaceutical Company for the treatment of Alzheimer’s disease and other cognitive defects. This has been met with limited success. The Swiss company Santhera Pharmaceuticals has started to investigate it for the treatment of neuromuscular diseases. In 2010, early clinical trials for the treatment of Friedreich’s ataxia and Duchenne muscular dystrophy have been completed. In clinical trials, Idebenone (Raxone/Catena) had a positive impact on a measurement of respiratory function (Peak Expiratory Flow, or PEF) in non-ambulatory Duchenne muscular dystrophy patients who were not taking steroids. As of December 2013 the drug is not approved for these indications in North America or Europe. It is approved for the treatment of Leber's hereditary optic neuropathy (LHON) in Europe. Idebenone (Raxone) is indicated for the treatment of visual impairment in adolescent and adult patients with Leber’s Hereditary Optic Neuropathy (LHON). Because the number of patients with Leber's hereditary optic neuropathy is low, the disease is considered ‘rare’, and Raxone was designated an ‘orphan medicine’ on 15 February 2007. Idebenone is thought to help improve production of energy by restoring mitochondrial function, thereby preventing the cellular damage and the loss of sight seen in LHON. Idebenone is a rapidly absorbed, safe and well-tolerated drug and is currently the only clinically proven treatment option for Leber's hereditary optic neuropathy (LHON) patients.

Muscone is the key flavor component of musk that is one of the most popular natural perfumes. Muscone is a promising agent for treating intervertebral disc degeneration through its anti-inflammatory effects. Musk distributing into the brain through blood brain barrier provides the basis for its effect in treating brain disorders. Muscone may be a small active molecule with neuroprotective properties, and that inhibition of apoptosis and Fas is an important mechanism of neuroprotection by muscone. These findings suggest a potential therapeutic role for muscone in the treatment of stroke. Muscone has a protective effect against ischemia-reperfusion injury in cardiac myocytes, indicating that muscone may potentially provide therapeutic benefit in ischemia-reperfusion injury by inhibiting cellular oxidative stress and apoptosis.

Guanosine is an endogenous guanine nucleoside. Guanosine was shown to be protective in several in vitro and/or in vivo experimental models of central nervous system (CNS) diseases including ischemic stroke, Alzheimer's disease, Parkinson's disease, spinal cord injury, nociception, and depression. The mechanisms underlying the neurobiological properties of guanosine seem to involve the activation of several intracellular signaling pathways and a close interaction with the adenosinergic system, with a consequent stimulation of neuroprotective and regenerative processes in the CNS. Several guanosine analogues, i.e. acyclovir (and its oral prodrug valaciclovir), penciclovir (in its oral prodrug form, famciclovir) and ganciclovir, are widely used for the treatment of herpesvirus (i.e. HSV-1, HSV-2, VZV and HCMV) infections.

Zingerone is one of the active phenolic components isolated from Zingiber officinale. Zingerone is primarily present in dry ginger, but cooking or drying also converts gingerol into zingerone by a retroaldol reaction. Chemically synthesized zingerone is vanillyl acetone, which is a member of the phenolic alkanone group, and its varied pharmacological properties include antioxidant, anti-inflammatory, and anticancer activities. Thus, zingeroneshowed strong anti-angiogenic activity via the inhibition of MMP-2 and MMP-9 during tumor progression. Zingerone was likely to be broad-spectrum anti-inflammatory agents in most organs that suppressed the activation of NF-κB, the production of IL-1β, and the infiltration of inflammatory cells in mice. Zingerone effectively inhibits 1,2-dimethylhydrazine-induced colon carcinogenesis in male Wistar rats. Zingerone possess radioprotective effects in laboratory animals and in cultured cells in vitro. Zingerone produced marked improvement in stress induced irritable bowel disorder, which could be attributed to the powerful antioxidant nature, direct effect on the intestinal smooth muscle and adaptogenic nature. Analysis of the qualities that constituted zingerone irritation found that the sensations produced are predominantly burning and warmth, making it qualitatively similar to capsaicin.

Magnesium ascorbate is a non-acidic buffered form of Vitamin C and a source of the essential mineral Magnesium. The in vitro model system consisted of the isolated section of rat small intestine. The sources of magnesium ion (Mg2+) were magnesium chloride, magnesium sulphate, magnesium acetate, magnesium lactate, magnesium hydrocitrate and magnesium ascorbate. Magnesium ions from magnesium ascorbate were absorbed after the first 15 minutes to the highest extent of all salts, but after 120 minutes their absorption was the smallest of all. The use of magnesium ascorbate in food supplements may lead to an additional exposure to vitamin C and Magnesium.

3-N-Butylphthalide (NBP), a family comprised of optical isomers l-3-N-butylphthalide (l-NBP) and d-3-N-butylphthalide (d-NBP), with l-NBP being an extract from seeds of Apium graveolens Linn. (celery) and dl-3-N-butylphthalide (dl-NBP), a synthetized version, has been studied for its significant neuroprotective effects. NBP showed neuroprotective effects by decreasing oxidative damage, inhibiting inflammatory responses, improving mitochondrial function, and reducing neuronal apoptosis. NBP received approval by the State Food and Drug Administration of China for clinical use in stroke patients in 2002. It demonstrates a potential for the treatment of central nervous system diseases, including Parkinson’s disease, Alzheimer’s disease.

S-Carboxymethylcysteine (carbocysteine or SCMC; also available in the lysinate form, SCMC-Lys) is a mucoactive drug, has antioxidant and anti-inflammatory properties. Carbocysteine has been recently recognized as an effective and safe treatment for the long-term management of COPD, able to reduce the incidence of exacerbations and improve patient quality of life. Moreover, carbocysteine was effective in counteracting some symptoms associated with cancer cachexia. Preclinical and clinical studies have demonstrated that the antioxidant and anti-inflammatory properties of carbocysteine are more important than mucolysis itself for its therapeutic efficacy. Therefore, carbocysteine may be able to reverse the oxidative stress associated with several chronic inflammatory diseases, such as cardiovascular diseases and neurodegenerative disorders.

Mangiferin, a bioactive compound derived primarily from Anacardiaceae and Gentianaceae families and found in mangoes and honeybush tea, has been extensively studied for its therapeutic properties. Mangiferin has shown promising chemotherapeutic and chemopreventative potential. In traditional medicine, different cultures have cultivated and processed mangiferin rich plants for the treatment of a range of illnesses including cardiovascular disease, diabetes, infection and cancer. Mangiferin is primarily implicated in down-regulating inflammation, causing cell cycle arrest, reducing proliferation/metastasis, promoting apoptosis in malignant cells and protecting against oxidative stress and DNA damage. Mangiferin also enhances the capacity of the monocyte-macrophage system and possesses antibacterial activity against gram-positive and gram-negative bacteria.
