متن کاملAbsolute configuration of Cecropia juvenile hormone.
The absolute configuration of the predominant Cecropia hormone, methyl 12,14-dihomojuvenate, has been determined to be methyl (E,E)-(10R,11S)-(+)-10,11-epoxy-7-ethyl-3,11-dimethyl-2, 6-tridecadienoate (I). The less abundant hormone, methyl 12-homojuvenate, can be presumed by analogy to have the corresponding 3,7,11-trimethyldienoate structure (II). The assignment has been established with micro...
متن کاملTotal 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 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....
متن کاملOn the Specificity of Juvenile Hormone Biosynthesis in the Male Cecropia Moth *
The accessory sex glands (ASG) of adult male Cecropia contain an enzyme that methylates juvenile hormone acids (JH-acids) in the presence of S-adenosyl-L-methionine (SAM). The methyltransferase is highly specific. The reaction rates decrease in the order JH-I-acid, JH-II-acid and JH-III-acid; in each case the natural enantiomer is esterified predominantly. Methyltrans ferase activity with the ...
