Estradiol can be used for the research of cancers, neurodegenerative diseases and neural tissue engineering.

Isoprenaline (Isoproterenol) hydrochloride is a non-selective, orally active β-adrenergic receptor agonist. Isoprenaline has potent peripheral vasodilator, bronchodilator, and cardiac stimulating activities. Isoprenaline can be used for the research of bradycardia and bronchial asthma.

Resveratrol (trans-Resveratrol; SRT501) is a CNS-penetrant natural polyphenolic phytoalexin that possesses anti-oxidant, anti-inflammatory, cardioprotective, and anti-cancer properties. Resveratrol (SRT 501) has a wide spectrum of targets including mTOR, JAK, β-amyloid, Adenylyl cyclase, IKKβ, DNA polymerase. Resveratrol also is a specific SIRT1 activator. Resveratrol is a potent pregnane X receptor (PXR) inhibitor. Resveratrol is an Nrf2 activator, ameliorates aging-related progressive renal injury in mice model. Resveratrol increases production of NO in endothelial cells.

Acetaminophen (Paracetamol) is a selective cyclooxygenase-2 (COX-2) inhibitor with an IC₅₀ of 25.8 μM; is a widely used antipyretic and analgesic agent.. Acetaminophen is a potent hepatic N-acetyltransferase 2 (NAT2) inhibitor. Acetaminophen induces ferroptosis and leads to acute liver injury in mice model.

3,4-Dihydroxyphenylpyruvic acid is a nucleoside metabolite.

2,2'-Biphenol (o,o'-Biphenol) is an anti-inflammatory agent and the major non-protein-bound phenolic metabolite activated by rat bone marrow homogenate and hydrogen peroxide. 2,2'-Biphenol inhibits lipopolysaccharide (LPS) (HY-D1056)-induced COX-2 mRNA and protein expression. 2,2'-Biphenol suppresses the binding of AP-1 and NF-κB to their respective consensus sequences. 2,2'-Biphenol is applicable to research related to inflammation.

2-Hydroxyphenylethanol is a molecular chaperone that rescues misfolded P123S mutant pendrin, promoting translocation from the cytoplasm to the plasma membrane. 2-Hydroxyphenylethanol can be used for the research of pendred syndrome.

Capsaicin ((E)-Capsaicin), an active component of chili peppers, is a TRPV1 agonist. Capsaicin induces a nociceptive response by binding to its receptors. Capsaicin has analgesic effects on neurological disorders. Capsaicin has antioxidant, anti-inflammatory, anti-cancer effects.

Curcumin (Diferuloylmethane), a natural phenolic compound, is a p300/CREB-binding protein-specific inhibitor of acetyltransferase, represses the acetylation of histone/nonhistone proteins and histone acetyltransferase-dependent chromatin transcription. Curcumin is a photosensitizer against microorganisms. Curcumin shows inhibitory effects on NF-κB and MAPKs, and has diverse pharmacologic effects including anti-inflammatory, antioxidant, antiproliferative and antiangiogenic activities. Curcumin induces stabilization of Nrf2 protein through Keap1 cysteine modification.

Norepinephrine (Levarterenol; L-Noradrenaline) is a potent adrenergic receptor (AR) agonist. Norepinephrine activates α₁, α₂, β₁ receptors.

(-)-Epigallocatechin Gallate (EGCG) is a major polyphenol in green tea, which can inhibit cell proliferation and induce cell apoptosis. (-)-Epigallocatechin Gallate inhibits glutamate dehydrogenase 1/2 (GDH1/2, GLUD1/2) activity. (-)-Epigallocatechin Gallate has a potent anticancer, antioxidant and anti-inflammatory properties against various types of cancers such as colorectal cancer, myeloid leukemia, thyroid carcinoma.

Liothyronine is an active form of thyroid hormone. Liothyronine binds to thyroid hormone receptors TRα and TRβ with K_is of 2.33 and 2.29 nM for hTRα and hTRβ, respectively. Liothyronine also binds to PVR and blocks the interaction of TIGIT/PVR.

Luteolin (Luteoline), a flavanoid compound, is a potent Nrf2 inhibitor. Luteolin has anti-inflammatory, anti-cancer properties, including the induction of apoptosis and cell cycle arrest, and the inhibition of metastasis and angiogenesis, in several cancer cell lines, including human non-small lung cancer cells.

Urolithin A, a gut-microbial metabolite of ellagic acid, exerts anti-inflammatory, antiproliferative, and antioxidant properties. Urolithin A induces autophagy and apoptosis, suppresses cell cycle progression, and inhibits DNA synthesis.

Vancomycin hydrochloride is an antibiotic for the treatment of bacterial infections. It acts by inhibiting the second stage of cell wall synthesis of susceptible bacteria. Vancomycin also alters the permeability of the cell membrane and selectively inhibits ribonucleic acid synthesis.

Kaempferol (Kempferol), a flavonoid found in many edible plants, inhibits estrogen receptor α expression in breast cancer cells and induces apoptosis in glioblastoma cells and lung cancer cells by activation of MEK-MAPK. Kaempferol can be uesd for the research of breast cancer.

5-Aminosalicylic acid (Mesalamine) acts as a specific PPARγ agonist and also inhibits p21-activated kinase 1 (PAK1) and NF-κB. 5-Aminosalicylic acid can inhibit the activity of osteopontin (OPN).

Genistein, a soy isoflavone, is a multiple tyrosine kinases (e.g., EGFR) inhibitor which acts as a chemotherapeutic agent against different types of cancer, mainly by altering apoptosis, the cell cycle, and angiogenesis and inhibiting metastasis.

Apigenin (4',5,7-Trihydroxyflavone) is a competitive CYP2C9 inhibitor with a K_i of 2 μM.
