Biological Activity

(S)-Methoprene is a synthetic juvenile hormone analogue that acts as an agonist of the insect juvenile hormone receptor Methoprene-tolerant (Met). Activation of Met by (S)-methoprene stimulates juvenile hormone signaling pathways, promoting downstream transcription of genes involved in ribosomal biogenesis and vitellogenesis. Consequently, this disrupts normal insect growth and development, effectively preventing the transition from pupae to adult forms. [1][2]
