Continuing our search for natural product-based compounds for the control of B. longissima Larvae, 25 stilbene analogs were synthesized and evaluated for insect antifeedant activity against third-instar larvae of B. longissima for the first time. Among all the tested compounds, especially compounds 3a, 3c, and 6 showed pronounced antifeedant activities with AFC50 values of 0.218, 0.327, and 0.226 mg/mL, respectively. The different antifeedant activity ranges of these compounds indicated that variation of chemical structures in the stilbene skeleton markedly affected the activity profiles of this compound class, and some important SAR information has been revealed from it. In addition, to understand the structural requirements for antifeedant activities of the 25 synthesized stilbene analogs, a comparative molecular field analysis (CoMFA) model, which yielded the leave-one-out (LOO) cross-validated correlation coefficient (q 2) of 0.533 and a non-cross-validated correlation coefficient (r 2) of 0.929, was constructed. Together, these preliminary results may be useful in guiding further modification of stilbenes in the development of potential new antifeedants.

A number of 2,4-thiazolidinedione derivatives of aryl-substituted cinnamic acid were synthesized and studied for their antihyperglycemic activity in neonatal streptozotocin- induced diabeticWistermale rats. Substitution of the aryl ring resulted in higher activity. 3-(2,4-Dimethoxyphenyl)- 2-{4-[4-(2,4-dioxothiazolidin-5-ylmethyl)phenoxy]-phenyl}- acrylic acid methyl ester (Thz7), was found to be most active compound in this series which showed that disubstitutions on aryl ring by electron releasing groups were found suitable for promising antihyperglycemic activity. Increase in the ester carbon chain length decreased the activity.

A re-investigation of resveratrol synthesis by Perkins reaction allowed to improve this method and to determine the configuration of the intermediates. The results were applied to the synthesis of several aryl cinnamic acids for biological evaluation.
