Quassin and 8 congeners, 1-9, were identified as active principles in Picrasma quassioides for the paralytic/acute insecticidal activity upon subcutaneous injection in the American cockroach. The activity was prolonged by applying the metabolic inhibitors for oxidation and esterification before injecting the quassinoids. The nature of the insecticidal activity seems to differ from that of other...
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
Fractions obtained from partitioning of aerial methanolic extract of Euphorbia Aellenii with chloroform (E2), ethyl acetate (E3), n-butanol (E4) and water (E5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. Sample E2 appeared to have significant phytotoxic activity. In the insecticidal screening study o...
A new series of N-oxydihydropyrrole derivatives was synthesized and evaluated for insecticidal activity against Nilaparvata lugens and Myzus persicae. Various substituents were introduced to the 1-position of the dihydropyrrole ring, and the derivatives obtained exhibited systemic and/or contact insecticidal activity. The structure-activity relationship revealed that small alkyoxy and alkoxyalk...
W.C. RICE. 1999. A PCR-based method was developed for the rapid detection of vip3A gene encoding a novel Bacillus thuringiensis vegetative insecticidal protein with a wide spectrum of activities against lepidopteran insects. Specific primer combinations (three primers for the normal strand and two primers for the complementary strand) were capable of generating diagnostic fragments that success...
