Anilines

TMB is an excellent colorimetric substrate for detection of horseradish peroxidase labelled probes and is used with peroxidase and peroxidase coupled systems, particularly in ELISA techniques. It produces a soluble end product, which is blue in color and can be read spectrophotometrically. TMB has also been used in the quantitative determination of hemoglobin and in cytochemical staining for peroxidase. TMB is a hepatitis B antigen.

2,6-Dinitro-4-methylaniline is an amide that has been shown to induce cancer in animals. It has a high affinity for nucleic acids and forms covalent bonds with DNA. 2,6-Dinitro-4-methylaniline is metabolized by the liver and excreted by the kidneys into urine, where it can be detected in urine samples. This compound has been shown to bioconcentrate in organisms and accumulate in tissues as well as activate radiation. The activation of this compound is dose dependent and may be due to its ability to form covalent bonds with DNA.

4-Bromo-3,5-dihydroxybenzamide is a versatile building block that can be used as a reagent or as an intermediate in the synthesis of other compounds. It can also be used as a research chemical. 4-Bromo-3,5-dihydroxybenzamide has shown to be useful for the synthesis of complex organic compounds and is an excellent starting point for the preparation of novel scaffolds. This compound is also useful for making high quality products.

3,3'-Diaminobenzidine (DAB) is an organic compound derived from benzidine. It is the precursor to the synthetic fibre polybenzimidazole (PBI), which have high thermal and oxidative stability properties. DAB is water-soluble as the tetrahydrochloride salt and is used in immunohistochemical staining of nucleic acids and proteins. Research in Alzheimer's disease, Aβ protein amyloid plaques are targeted by a primary antibody, and subsequently by a secondary antibody, which is conjugated with a peroxidase enzyme. This will bind DAB as a substrate and oxidize it, producing an easily observable brown colour. 3,3’-Diaminobenzidine is also available as the tetrahydrochloride salt and the tetrahydrochloride hydrate.

4-Methoxybenzamide is a small molecule that has been shown to have anticancer activity in vitro and in vivo. It is a hydroxylated benzamide with an intramolecular hydrogen bond, which allows it to selectively bind to DNA at the C4' position of cytosine. The compound's anticancer effects are due to its ability to inhibit the transcription of genes involved in cancer cell proliferation and its ability to induce apoptosis via caspase activation. 4-Methoxybenzamide has been shown to be synergistic when used with other chemotherapeutics, such as cisplatin, doxorubicin or 5-fluorouracil. This drug also inhibits the uptake of these drugs by cancer cells, limiting their therapeutic effects on healthy tissues.

3-Chloro-2-nitroaniline is an organic compound that regulates the neuron and can be used in the treatment of Alzheimer's disease. It has been shown to bind to the potassium channel, which regulates the flow of potassium ions across neuronal membranes. 3-Chloro-2-nitroaniline also binds to the CB2 receptor, which is found on immune cells, and has been shown to be a potent agonist for this receptor. The affinity of 3-chloro-2-nitroaniline for the CB2 receptor is about 100 times greater than for the CB1 receptor. 3-Chloro-2-nitroaniline also binds to other proteins such as ABCA1 and Abca1, which regulate cholesterol transport in cells. 3-Chloro-2-nitroaniline is currently being studied as a potential drug candidate for treatment of Alzheimer's disease and other neurological disorders.
