Three polyhydroxy-2-phenylnaphthalenes (1-3) and the oxy analogue of tetrahydroxypavinan (4) were prepared and evaluated for their antioxidant properties (inhibition of diphenylpycrylhydrazyl radical (DPPH), reduction of iron (III) ion) and inhibition of 5-lipoxygenase (5-LO) activity. Their three-dimensional structures were established on the basis of spectroscopic data and semi-empirical calculations. Compounds 1 and 2 were found as potent 5-LO inhibitors as nordihydroguaiaretic acid (NDGA), whereas 4 is 2.5 times less potent than NDGA. The reliability of the 3-D structures with the 5-LO inhibition properties is discussed. Their antioxidant properties show that tested compounds are expected to act as redox inhibitors.

Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. in vivo) to form a multimer (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding domains on a protein or on different proteins.
4-aminoantipyrine/phenol in the presence of carbidopa, an anti-Parkinsonian drug, and othercatechols, including l-dopa, were monitored spectrophotometrically and by measuring hydrogen peroxide consumption. RESULTS Chromophore formation in all three enzyme/substrate systems was blocked in the presence of carbidopa and othercatechols. However, the rates of hydrogen peroxide consumption were not much affected
