the first polymer-on-polymer Mitsunobureaction, in which a polymeric phosphine is used simultaneously with a polymeric azodicarboxylate, is reported. This strategy employs the use of soluble oligomers generated from ring-opening methathesis polymerization. 31P NMR analysis revealed that the two polymers were interacting to generate the Mitsunobu products. Application to several substrates, as well

Nuclear factor-erythroid 2-related factor 2 (Nrf2) regulates the expression of over 200 genes of antioxidant and phase II drug-metabolizing enzymes, and is highly expressed in non-small cell lung cancer (NSCLC). Nine derivatives of 4-(2-cyclohexylethoxy)aniline were designed. Our previous study demonstrated that IM3829 increases radiosensitivity of several lung cancer cells in vitro and in vivo. Here, biological effects of IM3829 derivatives (2a-2i) were evaluated. Compound 2g derivative effectively inhibits mRNA and protein expression of Nrf2 and HO-1. In addition, we observed over two fold enhancement in IR-induced cell death, from $2.90\pm}0.22$ to $6.02\pm}0.87$, in H1299 cancer cell-line. Among the nine derivatives, compound 2g derivative exhibited the highest enhancement of radiosensitizing effect via inhibition of Nrf2 activity.

benzoxazines.' During the preparation of several of these substrates, we found that conversion of the required allylic alcohol to the bromide and 0-alkylation of 2-nitrophenol under basic conditions gave low yields of the desired products. We, therefore, sought a more direct approach involving nucleophilic substitution of an allylic alkoxide on 2-fluoro-lnitrobenzene. Nucleophilic aromatic substitution

New arylisothiocyanates corresponding to the formula ##STR1## wherein R represents alkyl, alkoxy or halogen X represents oxygen or sulfur and P represents an integer of from 2 to 5 are disclosed. They can be used for the regulation of plant growth especially for the dessication and defoliation of unlignified parts of plants above the soil.
