Variously substituted benzyl derivatives of chloronicotinyl insecticides were synthesized with a wide range of substituents including halogens, NO2, CN, CF, and small alkyl and alkoxy groups at the ortho, meta and para positions, as well as multiple-substituted benzyl analogues. Their binding activity to the alpha-bungarotoxin binding site in housefly (Musca domestica) head membrane preparations was measured. Among the compounds tested, the activity of the meta-CN derivative was the highest, being 20-100 times higher than those of imidacloprid, acetamiprid and nitenpyram. The synergized insecticidal activity against houseflies was also measured for selected compounds with the metabolic inhibitor, NIA16388 (propargyl propyl phenylphosphonate). For the nitromethylene analogues, including both benzyl and pyridylmethyl analogues, higher binding activity usually resulted in higher insecticidal activity. (C) 2000 Society of Chemical Industry.

The near infrared absorbing composition includes: a copper-containing polymer having a copper complex site at a polymer side chain; and a solvent, in which the copper complex site includes a site multidentate-coordinated to a copper atom and at least one selected from the group consisting of a site monodentate-coordinated to a copper atom and a counter ion to a copper complex skeleton, and a polymer main chain and a copper atom at the copper complex site are bonded to each other through the site monodentate-coordinated to a copper atom or the counter ion.

and to inhibit ERKs phosphorylation, without acting directly on microtubules and tubuline. Its theoretical recognition against duplex and quadruplexDNA structures have been compared to experimental thermodynamic measurements and by molecular modeling investigation leading to putative binding modes. Taken together these findings contribute to define this compound as potential Multitarget-Directed Ligands
