Synthetic pheromones that promote inter-male aggression in mice

Synthetic pheromones that promote inter-male aggression in mice

M Novotny et al. Proc Natl Acad Sci U S A. 1985 Apr.

Abstract

Two volatile constituents of male mouse urine, dehydro-exo-brevicomin and 2-(sec-butyl)-dihydrothiazole, have been found active in bioassays of inter-male aggressive behavior. The two synthetic compounds act synergistically when added to castrated male urine but not when added to water, and they provoke fighting that is quantitatively and qualitatively comparable to that elicited by intact male urine.
