Photostabilizers for Azadirachtin‐A (A Neem‐Based Pesticide)

Journal of Environmental Science and Health, Part B, 2003
Photostability of azadirachtin-A (a neem based pesticide) has been studied without and with adding stabilizers such as ter. butyl-p-cresol, 8-hydroxy quinoline and ter. butyl hydroquinone as thin film on glass surface and on leaf surface under sunlight and UV light.

In Vitro Azadirachtin Production

2008
The secondary metabolite azadirachtin (C35H44O16) is a tetranortriterpenoid obtained from the neem tree (Azadirachta indica). It has long been investigated for its biopesticidal properties. It is a natural insecticide, known to affect feeding, growth, reproduction and metamorphosis of the insect pests.

Enantioselective route to an azadirachtin substructure

Chirality, 1997
An enantioselective route to the hydroxyfuran acetal substructure 36 of azadirachtin is described. The enantiopure key intermediate 29 was obtained in both absolute configurations by a kinetic resolution experiment, making use of an optical pure cyclopentadiene.

A theoretical study on the conformations of azadirachtin

Journal of Molecular Structure: THEOCHEM, 1996
Abstract The conformation and the charge distribution of azadirachtin were analysed using molecular mechanics and AM1 calculations. The present paper reports our computational efforts that aim to characterise the skeletal conformational behaviour of azadirachtin and to determine the conformational flexibility of the functional groups present in the ...

Corpus cardiacum — a target for azadirachtin

Experientia, 1989
Azadirachtin A, an insect growth inhibitor derived from neem seed, when injected at a physiological dose, inhibits the hormonally controlled ovarian development inLocusta migratoria. Its tritiated dihydro derivative concentrates more in the corpus cardiacum than in the brain. Translocation and release of the neurosecretory proteins labeled with L-[35S]-
