(+)-octopamine is an enantiomer of octopamine, a naturally occurring phenolamine acting as a neurotransmitter in invertebrates. Octopamine is considered to be trace amine present in mammalian tissues at very low (nanomolar) concentrations. Generally, the (+)-enantiomers of octopamine are less active than the (-)-enantiomers at adrenergic receptors. However (+)-octopamine is more potent than the (-)-octopamine as an inhibitor of semicarbazide-sensitive amine oxidase.

Sodium 2-Mercaptobenzothiazole (sodium MBT) is utilized as a corrosion inhibitor and fungicide. By analogy to MBT, sodium MBT is identified as a skin sensitizer. Sodium 2-Mercaptobenzothiazole is also used to make rubber accelerators, as a preservative for latex paint and wood, a metal chelator, and a thermal stabilizer (methyl methacrylate copolymers, acrylonitrile polymers, polyester fibers, anion exchange resins, polyoxyphenylene, and silicon fluids), also used in electroplating (silver, nickel, and cobalt), to separate sulfide ore from copper ore, for dyeing textiles, in transmission fluids, and to prevent discoloration of freeze dried bananas; uses of 50% aqueous solution include as a corrosion inhibitor for nonferrous metals in antifreeze and coolants and in paper mill systems; used as a biocide in metalworking fluids and paper manufacturing.

Adrenalone is a keton form of the natural substrate epinephrine. Adrenalone is evidently formed in vivo by hydrolytic cleavage of the diester by esterases. It is an adrenergic receptor agonist. Adrenalone inhibits the norepinephrine synthesis and dopamine beta oxidase. It is known to have very weak sympathomimetic activity when compared to adrenaline. Adrenalone has the high radioprotective effect. It is a topical nasal decongestant. Adrenalone has hemostatic, sympathomimetic and vasoconstrictor therapeutic functions.

Guanoclor is an anti-hypertensive agent developed by Pfizer Ltd. (U.K.). It seems to be effective in various types of hypertension (unknown aetiology, renal, and malignant). It affects both systolic blood-pressure and diastolic blood-pressure. It is an adrenergic neurone-blocking agent, which also interferes with noradrenaline synthesis by inhibition of the enzyme dopamine beta-hydroxylase. Clinical use of the compound was first reported by Lawrie et al. (1964), who achieved satisfactory blood-pressure control in 60% of their cases with guanoclor alone, and in a further 18% with the addition of a thiazide diuretic. They also noted a significant reduction in urinary noradrenaline levels during guanoclor administration. Guanochlor has an affinity for the Na+/H+ exchanger ranging between 0.5 uM and 6 uM in different systems and is more potent than amiloride in all systems studied. It is suggested that guanochlor recognizes a binding site on the Na+/H+ exchanger that is distinct from the amiloride binding site.
