Nitrogenase is the metalloenzyme that catalyzes the nucleotide-dependent reduction of N(2), as well as reduction of a variety of other triply bonded substrates, including the alkyne, acetylene. Substitution of the alpha-70(Val) residue in the nitroge

Two-step redox switching in enantiopure helquat system [P-1](2+) ⇌ [P-1](•+) ⇌ [P-1](0) is demonstrated. The viologen-type electroactive unit embedded directly in the helical scaffold of 1 is responsible for the prominent chiroptical switching

Ferrocene-terminated oligo(phenylenevinylene) (OPV) methyl thiols have been prepared by orthogonal coupling of phenylene monomers. Ethoxy substituents on the phenyl rings improve the solubility of OPV, enabling the synthesis of longer oligomers. Self

Oxy-peptide nucleic acids (OPNAs) of [-NH-CH(CH2-CH2-Base)-CH2-O-CH2-CO-]-type main chain with four different types of nucleobases (Base = A, G, C, and U) or with an abasic side group (X) were synthesized. Melting curves of the 1:1 hybrids of o(A(n))

A tripyrrole peptide-Hoechst conjugate (FPH-1) has been designed which recognizes nine dA/dT base pair A/T rich dsDNA sequences at subnanomolar concentrations and complexes its targets at near diffusion controlled rates to form a fluorescent product.
