- Vomeropherine sind Pheromone, die über das vomeronasale Organ (Geruchsorgan bei Säugetieren, auch Jacobson-Organ) wirken sollen. Der Begriff „Vomerophine“ [zusammengesetzt aus latein. vomer, vomeris ‚Pflugschar‘ (anatom. ‚Pflugscharbein‘) und Pheromon] wurde von Luis Monti-Bloch und Mitarbeitern für diese Gruppe chemischer Substanzen geprägt.

- Pherines, also known as vomeropherines, are odorless synthetic neuroactive steroids that engage nasal and induce dose-dependent and reversible pharmacological and behavioral effects. Pherines target human chemosensory receptors and possibly other receptors such as the GABAA receptor and influence central nervous system activity. Currently known pherine molecules are being developed for the treatment of various medical conditions. Pherines specifically target nasal chemosensory cells and mediate selective modulation of brain areas like the limbic amygdala, hypothalamus, hippocampus, and prefrontal cortex. In clinical trials, pherines formulated for intranasal administration in ultra low doses (nanogram to low microgram quantities) showed rapid onset of efficacy (10–15 minutes) and an excellent safety and tolerability profile. Pherines are also minimally invasive (do not require systemic absorption) to exert their pharmacological effects and can be used on demand Pherines described in the scientific literature include PH10, , , and fasedienol (PH94B, Aloradine, or 4,16-androstadien-3β-ol, a positional isomer of androstadienol). Pherines are chemically and pharmacologically different from natural pheromones including androstadienone, androstenone, androstenol, androsterone, and estratetraenol. (en)
