Resveratrol (SRT 501) is a polyphenolic natural product, a plant antitoxin with antioxidant and chemopreventive activities. Resveratrol has a wide range of targets including COX, SIRT, LOC, etc. Resveratrol induces autophagy and apoptosis.

4-hydroxyphenylacetic acid (parahydroxy phenylacetate) is a major microbiota-derived metabolite of polyphenols. 4-hydroxyphenylacetic acid(p-Hydroxyphenylacetic acid) is involved in the antioxidative action. 4-hydroxyphenylacetic acid(p-Hydroxyphenylacetic acid) induces expression of Nrf2.

Curcumin (Natural Yellow 3) is a phenolic natural product, an inhibitor of histone acetyltransferase p300 CREB (IC50=25 μM) with specificity. Curcumin has a wide range of pharmacological activities such as antitumor, anti-inflammatory and antioxidant.

Luteolin (Luteolol) belongs to the flavonoid group of natural products and is a Nrf2 inhibitor, PDE inhibitor. Luteolin has a wide range of biological activities including antitumor, antioxidant, anti-inflammatory, antimicrobial, antiviral, antiallergic, and procoagulant.

Bardoxolone (CDDO) is a synthetic oleanane triterpenoid that blocks the cellular synthesis of inducible nitric oxide synthase and inducible COX-2 in INF-γ-activated mouse macrophages with an IC50 value of 0.4 nM. By suppressing reactive oxygen and nitrogen species (ROS RNS) formation, it promotes the cellular control of ROS RNS levels that would lead to DNA damage associated with tumorigenesis. In various Y cell lines, Bardoxolone has been shown to specifically inhibit proliferation and induce apoptosis. Mechanism studies revealed that Bardoxolone is a ligand for peroxisome proliferator-activated receptor γ, and also that it induces genes regulated by Nrf2, including heme oxygenase-1 and eotaxin-1, which play a role in antioxidant response element signaling activity.

Sulforaphane is a natural isothiocyanate that activates Nrf2 and inhibits AMPK-dependent signaling. Sulforaphane has antitumor and anti-inflammatory activities by increasing the transcription of tumor suppressor proteins and inhibiting histone deacetylase activity.

Mangiferin (Hedysarid) is used for antidiabetes. Extracted from Mangifera indica L.

Danshensu (Dan shen suan A) is an active ingredient of *Salvia miltiorrhiza* with extensive cardiovascular benefits.

Hinokitiol (4-Isopropyltropolone) can inhibit ultraviolet B-induced apoptosis in keratinocytes and strongly suggest that the inhibitory mechanism is due to the antioxidant activity of metallothionein induced by the agent. Also, Hinokitiol modulates estrogen receptor signaling and inhibits proliferation of human breast cancer cells.

2-tert-Butyl-1,4-benzoquinone (TBQ), an electrophilic metabolite of butylated hydroxyanisole (BHA), activates Nrf2 and S-arylates its negative regulator Keap1 in RAW264.7 cells.

Dimethyl fumarate (DMF) is an Nrf2 activator with oral activity and blood-brain barrier permeability. Dimethyl fumarate has antimicrobial, anti-inflammatory, and immunomodulatory activities and has been used in the study of multiple sclerosis.

Pyridoxine (Vitamin B6) is the 4-methanol form of vitamin B6 and is converted to pyridoxal 5-phosphate in the body. Although pyridoxine and vitamin B6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading.

Methyl 3,4-dihydroxybenzoate (Protocatechuic acid methyl ester), a key metabolite of antioxidant polyphenols in green tea, exhibits significant antioxidant and anti-inflammatory properties.

Pyridoxine hydrochloride (Vitamin B6) is the 4-methanol form of vitaminB6 which is converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid.

Brusatol (NSC-172924) is a natural product isolated from the Brucea javanica plant. It inhibits Nrf2.

(R)-Sulforaphane (L-Sulforaphane) is a potent inducer of the Keap1 Nrf2 ARE pathway.

1. Eriodictyol (Huazhongilexone) is a flavonoid with anti-inflammatory and antioxidant activities. 2. Eriodictyol may possess antidiabetic properties through increasing glucose uptake and improving insulin resistance. 3. Eriodictyol may be a potential therapeutic resource for Atopic dermatitis and an adjunctive agent to control itchiness inAtopic dermatitis.

Carnosol is an Nrf2 activator, increasing Nrf2 levels and promoting heme oxygenase 1 (HMOX1) expression. It is a ribosomal S6 kinase (RSK2) inhibitor and can be used in gastric cancer-related research with an IC50 value of approximately 5.5 μM.

Astilbin (Neoastilbin) is actions Flavonoid phytochemical found in St. John′s wort and Traditional Chinese Medicine herbal preparations.

Dehydroglyasperin C is a potent NAD(P)H:oxidoquinone reductase (NQO1) and phase 2 enzyme inducer. Dehydroglyasperin C possesses potent antioxidant, cancer chemopreventive, and neuroprotective activities, it has protective effects against chronic diseases

Praelolide, a potent Nrf2 activator, disrupts Keap1-Nrf2 protein-protein interactions through noncovalent binding to Keap1, inhibiting osteoclastogenesis and the production of reactive oxygen species (ROS). With its potential in osteoclastogenic bone disease research, Praelolide presents a promising avenue for therapeutic exploration.

Toralactone is isolated from cassia seed and shows antibacterial activity against methicillin-resistant Staphylococcus aureus.

1. Corynoline ((+)-Corynoline) is an acetylcholinesterase inhibitor.

Kinsenoside ((+)-Kinsenoside) shows significant antihepatotoxic, and anti-inflammatory activities. Kinsenoside could be useful for repairing beta cells in pancreatic islet injury as well as improving its function, it could promote the glucose tolerance of acute glucose increase in both diabetic and normal healthy rats. Kinsenoside inhibits osteoclastogenesis from macrophages by attenuating RANKL-induced NF-κB and NFATc1 activities, which in turn, prevents bone loss from OVX mice.
