Fourteen neo-clerodane diterpenoids isolated from Scutellaria altissima ( Lamiaceae) were tested for insect antifeedant activity against Leptinotarsa decemlineata Say. Potato leaf disks treated with small amounts of the compounds (concentration 1000, 100, 10 ppm) resulted in good to very good antifeedant activity. Clerodin (1), scutecyprin (11) and 11-epi-scutecolumnin C (12) showed strong feeding inhibition at 1000 ppm and exhibited significant antifeedant activity at a concentration of 100 ppm. Activity was established by calculating the feeding ratio (FR) between the consumed areas of treated disks (CTD) and control disks (CCD). For comparison, FR50 values were determined as the FR at a CCD of 50%. Structural features of the compounds associated with the changes in activity and structure-antifeedant activity relationships are discussed. For the first time the anti-feedant activity has been evaluated of neo-clerodane diterpenoids with an unusual R-configuration of the carbon atom C-11.

Several angularly functionalized decalins, synthethized during the preparation of three keto diacetate decalins, models for clerodane diterpenoids, were tested for antifeedant activity against the spruce budworm, Choristoneura fumiferana. Definite biological activity was observed for some of these compounds. A structure–activity relationship was discussed on the basis of these results.
