Fish Poisons as Insecticides

Saponins as Insecticides: a Review

Chaieb, I. 2010. Saponins as insecticides: a review. Tunisian Journal of Plant Protection 5: 3950. Saponins are heterosides (substances containing in their structure one or more sugar molecule) of plant origin. This type of molecules has an interesting pesticide potential and this review constitutes an inventory of principal researches realized in this direction. In the first part of this revie...

Fragments of the Bacterial Toxin Microcin B17 as Gyrase Poisons

Fluoroquinolones are very important drugs in the clinical antibacterial arsenal; their success is principally due to their mode of action: the stabilisation of a gyrase-DNA intermediate (the cleavage complex), which triggers a chain of events leading to cell death. Microcin B17 (MccB17) is a modified peptide bacterial toxin that acts by a similar mode of action, but is unfortunately unsuitable ...

Two new flavonol glycosides as DNA topoisomerase I poisons.

Flavonoids are secondary plant metabolites whose anticancer properties are actually being studied from an epidemiological and pharmacological point of view. They are believed to be implicated in the lower risk of some forms of cancer observed in Asian countries, due to their capacity to control cell proliferation, to act on certain regulatory enzymes as protein kinases or topoisomerases. Based ...

Bacteria, spirochetes, and rickettsia as insecticides.

Most bacteria pathogenic to insects are classified in the families Pseudomonadaceae, Enterobacteriaceae, Lactobacillaceae, Micrococcaceae, and Bacilliaceae; spirochetes and rickettsia are in the families Spirochaetaceae and Rickettsiaceae, respectively. Except for Bacilliaceae, these families contain nonsporulating microorganisms. Most spore-forming bacteria pathogenic to insects belong to the ...
