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.

Analogs of tubulin assembly inhibitors such as colchicine, combretastatin, and 3,4,5-trimethoxybiphenyl which incorporate a 6-diazo-2,4-cyclohexadienone (o-quinone diazide) ring have been synthesized and characterized. The compounds synthesized include 6-diazo-4-(2',3',4'-trimethoxyphenyl)cyclohexa-2,4-dien-1-one and its 3-methyl and 3-ethyl analogs (1a-c), 6-diazo-3-(2,3,4-trimethoxyphenyl)-2,4-cyclohexadien-1-one and its 4-methyl and 4-ethyl derivatives (2a-c), 4-[Z-2-(3',4',5'-trimethoxyphenyl)ethenyl]-6-diazocyclohexa-2,4-dienon e (3), 3-[Z-2-(3',4',5'-trimethoxyphenyl)ethenyl]-6-diazocyclohexa-2,4-dien-1 -one (4), the corresponding dihydro derivatives (5, 6) and two isomeric diazocyclohexadienones derived from N-acetylcolchinol (7, 8). Compounds in which the cyclohexadienone oxygen is approximately isostructural with carbonyl or hydroxy functions of the parent compounds exhibit good activity in the tubulin assembly inhibition assay. 2'-Alkyl-4'azido-3,4,5-trimethoxy-1,1'-biphenyls also show good activity as tubulin assembly inhibitors.

An array of cis-, trans-, and dihydrostilbenes and some N-arylbenzylamines were synthesized and evaluated for their cytotoxicity in the five cancer cell cultures A-549 lung carcinoma, MCF-7 breast carcinoma, HT-29 colon adenocarcinoma, SKMEL-5 melanoma, a
