Total synthesis of the racemic form of the second juvenile hormone (methyl 12-homojuvenate) from the cecropia silk moth.
Methyl cis-10-epoxy-3,7,11-trimethyl-trans,trans-2,6-tridecadienoate has been stereoselectively synthesized in 12 steps starting from methyl trans-gamma-bromo-beta,beta-dimethylacrylate and 1-acetyl-1-methylcyclopropane. The final product proved to be identical with the second, less abundant juvenile hormone (methyl 12-homojuvenate) isolated from the Cecropia silk moth. The biological activitie...
متن کاملThe accessory sex glands as the repository for juvenile hormone in male cecropia moths.
Gas chromatographic determinations, bioassays, and radio-labelling experiments show that the juvenile hormone in adult male Hyalophora cecropia is accumulated exclusively in the accessory sex glands. Moths do not store measurable quantities of juvenile hormone if their accessory sex glands are removed shortly after adult eclosion.
متن کاملActivity of juvenile hormone acid in brainless, allatectomized diapausing cecropia pupae.
Pupal diapause in the cecropia silkmoth is terminated by activation of the prothoracic glands. Implantation of adult male cecropia corpora allata or injection of juvenile hormone-I (JH-I) or juvenile hormone-I acid (JH-I acid) causes initiation of development in debrained, allatectomized diapausing pupae. The subsequent development results in formation of second pupae or pupal-adult intermediat...
متن کاملActive transport by the cecropia midgut. V. Loss of potassium transport during larval-pupal transformation.
Few serious attempts have been made to study either alterations of active ion transport during ontogenic development or the developmental consequences of altered ion environments within and around cells (see Kroeger, 1966 and Harvey & Haskell, 1966 for references). Nevertheless, to cite but a few examples of the importance of the ionic mileau for molecular activities associated with development...
متن کاملOn the biosynthesis of juvenile hormone in the adult Cecropia moth.
tides. Origin and nature of these substances, which are characterized by their lacking binding capacity for charcoal, are not yet clear. CHOU and SCHERB A U M 3 1 working with Tetrahymena described an accumulation of acid-soluble phosphorylated deoxysugars by release from existing structures after a heat treatment. The question, if degradation products from D N A (e. g. deoxynucleosides, cf. 1....
