However. the bioactive conformations of anthranilic diamides are still unclear until now. In the present study, DFT-based potential energy surface scanning was used to detect the low energy conformations of chlorantraniliprole, then were used respectively in the structure alignment for a series of anthranilic diamide compounds followed by detailed CoMFA and CoMSIA analyses. Finally, the bioactive conformations of anthranilic diamide insecticides were revealed from a series of low energy conformations, which might provide some clues for future insecticide design.展开更多

The obtained copolymer exhibits the expected structure as indicated by the result of characterization. Two amino acids (L-arginine, L-tyrosine) were covalently attached to the copolymer after converting the sulfonate group, to sulfonyl chloride. So the new reactive graft copolymer (PTMG-g-PEG-CH2CH2CH2SO3-Na+) is expected to be very useful in attachment of potentially bioactive moieties to polymer via a hydrophilic PEG spacer.展开更多
