Pyrithiamine is an antimicrobial agent that inhibits the growth of bacteria by disrupting the disulfide bond between two cysteine residues. It has been shown to inhibit the formation of bacterial spores, which are resistant to many antibiotics. Pyrithiamine also has antioxidant properties and can reduce oxidative stress in neurons, leading to neuronal death. This drug also has a strong effect on energy metabolism and may be used as a treatment for mitochondrial diseases.

3-Amino-4-hydroxybenzoic acid hydrochloride (3ABA) is a crystalline compound with a molecular formula of C6H5NO2. It is an acidic compound that is soluble in water and alcohol, but not in ether. 3ABA has been used as the starting material for the synthesis of many other organic compounds. It can be obtained by reacting phenol with chlorobenzoyl chloride to form the chlorobenzoate salt, which on hydrolysis yields 3ABA. This compound has also been used as a reagent for synthesizing carbon nanotubes. The crystal structure of 3ABA was determined using X-ray diffraction data from crystallographic studies, and it was found to have three independent molecules per unit cell. Diffraction indicated that each molecule is composed of two benzene rings joined by a single bond between carbon atoms 1 and 2 and another bond between carbon atoms 2 and 3.

2-Aminoresorcinol is a synthetic chemical compound that inhibits the reaction of amines with chlorine atoms. It is used as an intermediate in the production of resorcinol and 2-aminophenol. The reaction mechanism involves the formation of a chloramine (chlorine atom attached to an amine) which, in turn, reacts with malonic acid to produce an intermediate that undergoes intramolecular hydrogen transfer. This reaction results in the formation of a chloroform molecule. A second step involves hydroxylation by hydrochloric acid, which leads to the formation of chloral hydrate. In this way, 2-aminoresorcinol can be used for the synthesis of both resorcinol and 2-aminophenol. 2-Aminoresorcinol is also known for its inhibitory effects on certain reactions involving amines and sulfur compounds such as thiourea and carbonyl compounds such as malonic acid.

1-Aminoadamantane sulphate is a drug that has been used for the treatment of autoimmune diseases, such as multiple sclerosis and chronic inflammatory demyelinating polyneuropathy. It inhibits Na channels in nerves and therefore blocks the transmission of nerve impulses. 1-Aminoadamantane sulphate has also shown to inhibit amyloid protein formation, which is associated with Alzheimer's disease. This drug binds to an adenine nucleotide and inhibits the transport of hydrogen fluoride into cells. The drug also has anti-viral properties. 1-Aminoadamantane sulphate is able to bind to calcium ions and prevent the binding of viruses to cells by interfering with their ability to attach themselves to the cell surface.

Tridodecylmethylammonium chloride (TDMAC) is a biocompatible and non-toxic polymer that is used in the manufacture of sensors. TDMAC can be used as a coating on electrodes to increase their sensitivity to changes in pH and ionic strength. TDMAC is also used as a blood substitute, and has been shown to have anticoagulant properties. TDMAC has been shown to be effective at preventing heparin-induced thrombocytopenia when combined with dextran sulfate. This polymer has also been studied for use in biosensors and bioelectrochemical impedance spectroscopy devices.

5-Aminopyridine-3-carboxylic acid (5APC) is a structural analog of nicotinic acid that has been shown to have anti-inflammatory effects. 5APC inhibits the production of inflammatory cytokines, such as IL-10 and IL-17, by inhibiting the activation of NFκB and MAPK pathways. This drug also has significant inhibitory activities against dextran sulfate sodium (DSS)-induced acute colitis in experimental models. 5APC is thought to act by interrupting the assembly of p38 mitogen activated protein kinase (MAPK) and nuclear factor kappa B (NFκB) signaling complexes.
