Examples

“A B - hydroxy ketone ("pteroenone") with the formula CH40, has been reported to be the chemical defense compound (McClintock and Baker, 1998). Pteroenone causes a significant feeding deterrence in the Antarctic fishes[…]”

“Employing flash⟳ and high-pressure liquid chromatographic (HPLC) techniques, pteroenone (Figure⟳ 5.2), a linear β-hydroxyketone and the first example of a defensive secondary metabolite from a pelagic gastropod, was isolated from tissues[…]”

“In a bioassay-guided structure⟳ elucidation, pteroenone could be isolated and characterized as the main defensive principle of C. antarctica [82,83]. If embedded in alginate, this compound is a feeding-deterrent[…]”

“... provided a polypropionate-derived natural product, pteroenone (Figure⟳ 3.7), with strong feeding deterrence against fish⟳ predators […] Structure⟳ of pteroenone from the pteropod Clione limacina. (Yoshida et al.”
