Title: Extremely potent antifeedant neo-clerodane derivatives of scutecyprol A. Author: Rosselli S, Maggio A, Piozzi F, Simmonds MS, Bruno M. Journal: J Agric Food Chem; 2004 Dec 29; 52(26):7867-71. PubMed ID: 15612769. Abstract: Two known neo-clerodane diterpenoids, scutecyprol A (1) and scutalbin C (2), have been isolated from the acetone extract of the aerial parts of Scutellaria sieberi. The antifeedant activity of scutecyprol A (1), of its 15-oxo derivative (3), and of several halohydrins (4-9), synthesized starting from compounds 1 and 3, against Spodoptera littoralis have been determined and structure-antifeedant relationships are discussed.[Abstract] [Full Text] [Related] [New Search]
