1. Androsterone is one of the androgens, which are steroid hormones that affect the masculinization of the fetus and child and that maintain or create masculine traits in adults. Testosterone is the most active and abundant of the androgens. Androsterone was originally isolated from male urine in very small amounts. Many scientists believe it to be a metabolic byproduct of the breakdown of testosterone, and many scientists who study pheromones think it might be active in human relations.
2. A molecule of androsterone is very similar to testosterone. It consists of three six-member carbon rings and one five member ring joined along common sides. The molecular formula is C19 H30 O2. It has a beta-isomer called epiandrosterone, in which an hydroxyl group occupies a different geometric position. The ratio of androsterone to epiandrosterone is thought to be important in how masculine behavior is interpreted by others
3. Pheromones are well known in insect behavior. Their role in insect mating, navigation and nest protection has been studied, and active compounds have been isolated. Pheromones are the basis of some insect baits. Their effect on mammal behavior patterns is less well understood.
Androsterone, or 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone. It is a weak androgen with a potency that is approximately 1/7th that of testosterone.In addition, it can be converted to dihydrotestosterone (DHT) from 3α-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstenedione and testosterone, and as such, can be considered to be a metabolic intermediate in its own right.Androsterone is also known to be an inhibitory androstane neurosteroid,acting as a positive allosteric modulator of the GABAA receptor,and possesses anticonvulsant effects.The unnatural enantiomer of androsterone is more potent as a positive allosteric modulator of GABAA receptors and as an anticonvulsant than the natural form. Androsterone's 3β-isomer is epiandrosterone, and its 5β-epimer is etiocholanolone.
