3,3′-diindolylmethane or diindolylmethane (DIM), a natural product from cruciferous vegetables, which possesses chemopreventive activity in all stages of breast cancer carcinogenesis and is under investigation for the different form of cancer. DIM selectively induced proteasome-mediated degradation of the class I histone deacetylases (HDAC1, HDAC2, HDAC3, and HDAC8) without affecting the class II HDAC proteins (HDAC4, 5, 6, 7, and 10). Histone deacetylases are components of high molecular weight multisubunit complexes of co-repressor proteins that are recruited by transcription factors to the promoters to regulate gene expression. In addition, was identified another mechanism of action: DIM suppressed cancer cells proliferation and miR-30e down-regulated during this effect. miR-30e targeted the 3'-UTR of ATG5 to inhibit its translation. Thus DIM may through the miR-30e-ATG5 modulating autophagy inhibit the proliferation of gastric cancer cells. DIM is also sold as absorption-enhanced formulation under the brand name Patented BioResponse DIM®. BioResponse DIM supports a more favorable metabolism of estrogen and supports the production of 2 hydroxyestrone and 2-methoxyestrone, key metabolites in men and women. DIM is used to treat recurrent respiratory papillomatosis and it has been studied for patients with cervical intraepithelial neoplasia.

Oleuropein is a phenylethanoid, a type of phenolic compound found in olive leaf together with other closely related compounds such as 10-hydroxyoleuropein, ligstroside, and 10-hydroxyligstroside. Oleuropein is traditionally removed from olives due to its bitterness. In preliminary laboratory research, oleuropein had activity as an agonist of the G-protein estrogen receptor. Oleuropein inhibited the enzymatic activity of mammalian target of rapamycin (mTOR), suggesting that mTOR inhibition is at least one of the reasons for the reported anti-cancer properties of oleuropein.

α-Mangostin is a bioactive compound isolated from Garcinia mangostana L. known as the queen of fruits. Traditionally, numerous parts of G. mangostana have been utilized to treat various ailments such as abdominal pain, food allergies, arthritis, leucorrhoea, gonorrhea, diarrhea, and chronic ulcer. Experiments on animal have revealed that alpha-mangostin, an acid sphingomyelinase inhibitor, plays a protective role in diabetic neuropathy by relieving ER stress induced-renal cell apoptosis. Besides, it used against gastric ulcer, but this study was discontinued. α-Mangostin is also a histamine H1 receptor antagonist and is a specific inhibitor of lysine-specific demethylase 1 (LSD1), which has been reported to be overexpressed in several human cancers. α-mangostin has anti-carcinogenic effects against several cancers, including breast, colorectal cancers, and renal cell carcinoma. Thus, α-mangostin can be used to produce more potent LSD1 inhibitors with potential anticancer activity.

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.

Rosmarinic acid (α-o-caffeoyl-3,4-dihydroxyphenyllactic acid; RA) is a naturally occurring hydroxylated compound commonly found in species of the subfamily Nepetoideae of the Lamiaceae and Boraginaceae, such as Rosmarinus officinalis, Salvia officinalis, and Perilla frutescens. RA is biosynthesized from the amino acids L-phenylalanine and L-tyrosine by eight enzymes that include phenylalanine ammonia lyase and cinnamic acid 4-hydroxylase. Recently, RA and its derivatives have attracted interest for their biological activities, which include anti-inflammatory, anti-oxidant, anti-angiogenic, anti-tumor, and anti-microbial functions. Clinically, RA attenuates T cell receptor-mediated signaling, attenuates allergic diseases like allergic rhinitis and asthma, and 2,4-dinitrofluorobenzene-induced atopic dermatitis-like symptoms, protects from neurotoxicity, and slows the development of Alzheimer's disease. Rosmarinic Acid seems to be able to suppress 5-lipoxygenase and 5-HETE synthesis (a pro-inflammatory compound in the omega-6 metabolic chain). Rosmarinic acid appeared to be effective in suppressing allergies in a dose-dependent manner, with 30% of the placebo group reporting symptom relief compared to 55.6% of the 50mg group and 70% of the 200mg group.

Fulvic acid is primarily studied for its effects on plants and soil. Fulvic acid is an organic and natural electrolyte. Depending on the situation, Fulvic acid can act as an electron donor or acceptor and an oxidizer or reducer. Fulvic acid has exhibited the ability to enhance the availability and adsorption of nutrients as well as prolong their time of residence. In the chick animal model Fulvic acid disturbed the processing of procollagen II in articular cartilage. Fulvic acid has being shown to attenuate homocysteine-induced cyclooxygenase-2 expression in human monocytes. Fulvic acid, the main active principle of Shilajit (a natural substance found mainly in the Himalayas), blocks tau self-aggregation, opening an avenue toward the study of Alzheimer's therapy. People take fulvic acid by mouth for brain disorders such as Alzheimer’s disease, as well as respiratory tract infections, cancer, fatigue, heavy metal toxicity, and preventing a condition in which the body tissues do not receive enough oxygen (hypoxia).
