The glucosinolate, sinigrin (allyl- or 2-propenyl glucosinolate), present in several Gruciferae, was incorporated in varying concentrations into four different diet background mixtures to study the behavioural reactions of Mamestra configurata and Trichoplusia ni. Sinigrin concentrations were chosen to mimic normal levels in naturally occurring cruciferous plants, or to represent a plant during a particular stage in its growth cycle. One diet background mixture contained potassium chloride (KC1) and no stimulatory sugar or sugar alcohol, two backgrounds contained KC1 and a single sugar or sugar alcohol (sucrose or inositol, respectively), and the fourth background contained KC1 and both sugar and sugar alcohol (sucrose and inositol, respectively). Sinigrin acted primarily to reduce (deter) feeding in all backgrounds, although the effect varied with sinigrin concentration, background and species. When inositol or sucrose was included in the mixture, the deterrent effect of sinigrin was decreased in both species. When inositol and sucrose were present, suppression of the deterrent effect of sinigrin was greatest for M. configurata . The effects of mixtures were not predictable from a knowledge of the action of individual components. Differences observed between species may reflect different sensory capabilities.

The synthesis of 2-methylpyrrolo[1,2-a]pyrazin-1(2H)-one (2) present in the insect feeding deterrent peramine (1) through oxidation of the saturated lactam (3) is described. The preparation of the related 6- methyl-1H-pyrrolo[2,3-c]pyridin-7(6H)-one (12) through a Lewis-acid- catalysed cyclization of the amide acetal (7) is also described.

The decoction of the stem barks from Bowdichia virgilioides KUNTH is a folk remedy used to treat inflammatory disorders in Latin American and Brazil. In the present study, the wound healing activity of aqueous extract of the stem bark from B. virgilioides, called AEBv, was evaluated by the rate of healing by wound contraction and period of epithelization at different days post-wound using the wound excisional model. On day 9, the AEBv-treated animals exhibited significative reduction in the wound area when compared with controls. In wound infected with S. aureus, the AEBv significantly improved the wound contraction when compared to the saline-treated mice. The histological analysis showed that AEBv induced a collagen deposition, increase in the fibroblast count and few inflammatory cells than compared to saline-treated group. The expression of collagen type I was increased in the group treated with AEBv as indicated by immunohistochemical staining. In vitro, the AEBv was effective only against S. aureus but not against P. aeruginosa. Together, the results of this study demonstrate, for the first time, the healing and antimicrobiological effects of aqueous extract of the stem bark from B. virgilioides in the therapy of skin wounds.
