1e(-) waves assigned to the Ru(III)/Ru(II) couple, while, in aqueous solutions, 2a, 2b, and 2c show pH-dependent, 2e(-) waves corresponding to the formation of Ru(IV)=O complexes. Second-order rate constants, k(cat), for benzylalcohol oxidation by the Ru(IV)=O complexes were determined electrochemically, yielding values of 22(1) M(-)(1) s(-)(1) for [Ru(trpy)(H(2)dppi)(O)](2+), 9(3) M(-)(1) s(-)(1)

The rigid linear ligands 1a-g and the macrocycle 2 undergo self-assembly via coordination with copper(I) ions to generate the series of rigid-rack inorganic pseudorotaxanes 3a-g. These complexes have been characterized by analytical and spectroscopic methods. Their architecture has been confirmed by determination of the crystalstructures of 3e,f. The complex [Cu(2)(1e)(2)(2)](PF(6))(2) (3e) crystallizes
Synthesis, characterization, and electrocatalytic oxidation of benzyl alcohol by a pair of geometric isomers of [Ru(trpy)(4,4′-Me2dppi)(OH2)]2+ where 4,4′-dppi is 3,6-di-(4-methylpyrid-2-yl)pyridazine

The present invention relates to a pharmaceutical composition for the treatment of cancer, which contains, as an active ingredient, a pyridylpyridazine compound or a transition metal complex thereof.
As described above, the pyridylpyridazine compounds according to the present invention and the transition metal complexes thereof have anticancer activity and can be easily prepared at low cost. Thus, these compounds are useful as anticancer agents against various cancers, including lung cancer, adenocarcinoma, skin cancer, colon cancer, uterine cancer and brain cancer, which are expressed due to immune system abnormality.
A helicalaromaticoligoamide foldamer encapsulates tartaric acid with exceptional affinity, selectivity, and diastereoselectivity. The structure of the complex has been elucidated both in solution by NMR spectroscopy and in the solid state by X-ray crystallography, making it possible to rationalize the strong effects observed, particularly the role of hydrogen bonds between the hydroxyl and carboxylic
