產(chǎn)品描述：
Precocene II is a chromene that has been found in A. houstonianum and has anti-juvenile hormone activity.1,2,3 It inhibits juvenile hormone biosynthesis in isolated spontaneously active cockroach (P. americana) corpora allata when used at concentrations of 1 mM or higher.1 Precocene II (8 μg/cm2 coating in Petri dish) inhibits development of the corpus allatum in newly eclosed female milkweed bugs and causes allatal regression when applied 120 hours post-eclosion in normally developing females.2 It induces precocious metamorphosis in milkweed bug second-stage nymphs when applied as a coating to Petri dishes at concentrations of 0.4 and 0.7 μg/cm2.3 Precocene II inhibits ovarian development in various insects, including milkweed bugs, cotton stainers, apple maggots, and Mexican bean beetles. Precocene II also inhibits production of the trichothecene mycotoxin 3-acetyldeoxy nivalenol in F. graminearum (IC50 = 1.2 μM) without inhibiting fungal growth.41.Pratt, G.E., and Bowers, W.S.Precocene II inhibits juvenile hormone biosynthesis by cockroach corpora allata in vitroNature265(5594)548-550(1977)
