2',4-Dihydroxy-3-methoxychalcone is a chalcone that has been shown to have reactive properties. The compound was found to be cytotoxic to cancer cells in the presence of neutrophils, and it has been shown to inhibit the growth of t47d cells in culture. There is also evidence that 2',4-Dihydroxy-3-methoxychalcone may help regulate the microflora in the gut, which may help prevent obesity and diabetes. In epidemiological studies, 2',4-Dihydroxy-3-methoxychalcone was found to be protective against cancer, but more research is required.

O-Phospho-L-tyrosine is a phosphorylated form of L-tyrosine. It is used as an immunogen in the production of monoclonal antibodies. O-Phospho-L-tyrosine has also been shown to inhibit the enzyme indole alkaloids, which are responsible for the development of oral pathogens. The dephosphorylation of O-Phospho-L-tyrosine by tyrosine phosphatases leads to its conversion back to L-tyrosine. This compound can be detected by chromatographic analysis and is commonly used in analytical methods to identify natural compounds.

Betaine hydrochloride is a betaine prodrug that is metabolized by the body to form glycine and choline. Betaine hydrochloride has been shown to have anti-inflammatory properties, which may be due to its ability to inhibit surfactant sodium dodecyl (SDS) from activating enzymes such as polymerase chain reaction (PCR). Betaine hydrochloride also has been shown to improve disease activity in bowel disease patients and can be used as a dietary supplement for individuals with low levels of choline.

N-(4-Fluorophenyl)thiourea (FPTU) is a molecule that belongs to the class of thioureas. It has been shown to have a constant dihedral angle and is membrane transportable, which may be due to its ability to bind receptor proteins. FPTU has also been shown to inhibit chloride ion transport through the intestinal wall. In addition, it has been shown to have anti-inflammatory properties in animal models, which may be due to its ability to inhibit γ-aminobutyric acid (GABA) synthesis.

1-(3-Chlorophenyl) thiourea is a curcumin analog that has been shown to inhibit the epidermal growth factor (EGF) receptor. It is synthesized from 1,2-dichlorobenzene and urea in a two-step process. The anhydrous potassium carbonate is first converted to the potassium salt with an acid chloride. The second step is the reaction of this salt with urea in the presence of excess anhydrous potassium carbonate. This product has been shown to be effective against cancer cells and may be used as a potential anticancer agent for treatment of skin cancer. 1-(3-Chlorophenyl) thiourea inhibits EGF receptor by binding to it and preventing its activation, which prevents cell proliferation and reduces tumor size.

Camphorquinone-10-sulfonic acid hydrate is a soybean trypsin inhibitor that is used as a preparative agent in organic synthesis. It reacts with histidine, lysine residues, and other molecules to form a light-chain kinase that inhibits the action of the enzyme trypsin. Camphorquinone-10-sulfonic acid hydrate has been shown to be resistant to proteolysis by gastrointestinal enzymes. This agent also has diabetogenic properties by inhibiting the activity of membrane potential and chloride channels in pancreatic β cells. Camphorquinone-10-sulfonic acid hydrate forms an ion pair with choline, which can inhibit the enzyme acetylcholinesterase, leading to accumulation of acetylcholine at nerve endings.

Copper naphthenate is a cross-linking agent that contains copper and nitrogen atoms. It reacts with potassium dichromate, sodium carbonate, and other substances to form a copper complex. Copper naphthenate is used in the manufacture of biodiesel as a preservative. The product also has insecticidal properties, which have been shown to be due to its ability to inhibit the activity of chitin synthase enzymes found in insects. Copper naphthenate has been shown to be effective as a contraceptive when used vaginally and may also be used topically on the skin for this purpose. This product is acidic and should not be mixed with other acidic substances or materials such as plastics or rubber.
