ECDYSONE 20-MONOOXYGENASE ACTIVITY DURING LARVAL-PUPAL-ADULT DEVELOPMENT OF THE TOBACCO HORNWORM, MANDUCA SEXTA
Ecdysone 20-monooxygenase is the insect cytochrome P-450 dependent steroid hydroxylase system responsible for the conversion of ecdysone to 20-hydroxyecdysone. Using an in vitro radioassay, theExpand
Effects of plant flavonoids and other allelochemicals on insect cytochrome P-450 dependent steroid hydroxylase activity.
The plant flavonoids flavone, chrysin, apigenin, kaempferol, morin, quercetin, myricetin and phloretin were found to inhibit in a dose-dependent manner the cytochrome P-450 dependent ecdysoneExpand
Characterization of ecdysone 20-monooxygenase activity in wandering stage larvae of Drosophilamelanogaster: Evidence for mitochondrial and microsomal cytochrome P-450 dependent systems
Ecdysone 20-monooxygenase, the enzyme system that hydroxylates ecdysone to 20-hydroxyecdysone, was characterized in wandering stage larvae of Drosophila melanogaster using an in vitro radioassay inExpand
ECDYSONE 20-MONOOXYGENASE SYSTEMS IN A LARVAL AND AN ADULT DIPTERAN: AN OVERVIEW OF THEIR BIOCHEMISTRY, PHYSIOLOGY AND PHARMACOLOGY
Abstract Ecdysone 20-monooxygenase, the enzyme system that hydroxylates ecdysone to 20-hydroxyecdysone, was characterized in wandering stage larvae of Drosophila melanogaster and blood fed adultExpand
Ecdysone 20-monooxygenase activity throughout the life cycle of Drosophila melanogaster.
Effects of the compounds 2-methoxynaphthoquinone, 2-propoxynaphthoquinone, and 2-isopropoxynaphthoquinone on ecdysone 20-monooxygenase activity.
The effects of the natural compound 2-methoxy-1,4-naphthoquinone, isolated from the leaves of Impatiens glandulifera and the synthetic compounds 2-propoxy-1,4-naphthoquinone andExpand
Effects of the neem tree compounds azadirachtin, salannin, nimbin, and 6-desacetylnimbin on ecdysone 20-monooxygenase activity.
The effects of azadirachtin, salannin, nimbin, and 6-desacetylnimbin on ecdysone 20-monooxygenase (E-20-M) activity were examined in three insect species. Homogenates of wandering stage third instarExpand
Effects of the chitin synthetase inhibitor plumbagin and its 2-demethyl derivative juglone on insect ecdysone 20-monooxygenase activity
The chitin synthetase inhibitor plumbagin and its 2-demethyl derivative juglone were found to inhibit in a dose-response fashion the cytochrome P-450 dependent ecdysone 20-monooxygenase activityExpand
Effects of the adenylate cyclase activator forskolin and its inactive derivative 1,9-dideoxyforskolin on insect cytochrome P-450 dependent steroid hydroxylase activity
The adenylate cyclase activator forskolin and its pharmacologically inactive derivative 1,9-dideoxyforskolin were found to inhibit in a dose-dependent fashion the ecdysone 20-monooxygenase activityExpand
Infectibility of some new raspberry cultivars with arabismosaic and raspberry ringspot viruses and further evidence for variation in British isolates of these two nepoviruses
Summary In field trials at sites of an outbreak of arabis mosaic nepovirus (AMV) in England and of raspberry ringspot nepovirus (RRV) in Scotland, the results of exposure of some new raspberryExpand
