Mussels, which occupy important positions in marine ecosystems, attach tightly to underwater substrates using a proteinaceous holdfast known as the byssus, which is tough, durable, and resistant to enzymatic degradation....

The reagent-free C(2)-C(7) thermal cyclization of a nonconjugated aryl-yne-carbodiimide yielded a dibenzo[b,g][1,8]naphthyridine derivative, whose congeners are known to possess fascinating pharmacological properties. This is the first heteroaromatic compound prepared by...

Water-soluble non-conjugated thienyl tetraynes (3-6) were synthesized and their DNA cleaving activity was evaluated using electrophoresis, atomic force microscopy (AFM) and Escherichia coli (E. coli) transformation techniques. The amino-functionalized compound...

The green mussel Perna viridis LINNE can be kept in simulated seawater for more than 6 months in good condition. The mussel forms many threads by secreting an adhesive protein...

The reaction of chiral 1,2-bis(2-pyridylethynyl)benzene ligands with copper(I) ions in dichloromethane at room temperature gives rise to the formation of molecular rectangular boxes in high yields. The structures of these...

[reaction: see text] The air-, water-, and heat-stable palladium(II) complexes 2a and 2b are prepared by the reaction of palladium(II) salts with the new trans-bidentate nitrogen ligands, 1,2-bis(2-pyridylethynyl)benzenes. The structure...

A novel Hantzsch 1,4-dihydropyridine derivative could function in an organic solvent-free solution, and thus it could function in biological systems. These functions can be accomplished through regeneration of the reduced...
