An Insecticide Stabilized by Natural Zeolite

Journal of Thermal Analysis and Calorimetry, 1998
The synthetic pyrethroide insecticide (R, S)-α-cyano-3-phenoxybenzyl-IR, S-cis,trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanocarboxylate in solid form could be enclosed in and therefore stabilized by natural clinoptilolitic zeolite. The resulting host-guest complex exhibited characteristics different from those of the starting compounds and also ...

Insecticidal and cytotoxic effects of natural and hemisynthetic destruxins

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1994
The insecticidal and cytotoxic effects of 13 natural and hemisynthetic destruxins have been studied. DE shows insecticidal effects similar to those of DA, while DE and DA are more active than all the other natural compounds and analogues tested. Brominated destruxin is a relatively active analogue displaying particular modalities of cytotoxic effects ...
