(S)-(+)-Methoprene is a widely-used insect growth regulator. It is remarkable for its lack of significant effects against a wide variety of mammals, although concerns remain for its effects on arthropod development. Methoprene acts as an activator of the juvenile hormone receptor, known as Methoprene-tolerant or Met (K_d = 12.3 nM). Met is a transcription factor that, upon activation with juvenile hormone or methoprene, regulates gene expression that inhibits metamorphosis.

Insecticide; insect growth regulator.

ChEBI: (S)-methoprene is a methoprene. It is an enantiomer of a (R)-methoprene.

S)-methoprene alone is well tolerated by dogs and cats, with a low toxicity and high safety margin. Side effects experienced by dogs and cats after treatment with products containing (S)-methoprene can generally be attributed to the other active or inert ingredients.
