Anticomplement and antitussive activities of major compound extracted from Chimonanthus nitens Oliv. leaf.

Chimonanthus nitens Oliv. leaf (CNOL), as a traditional Chinese medicine, has been widely used for the treatment of influenza and colds over a long history. However, the mechanism of colds related to the effects of CNOL have been little studied.

Polyoxometalates covalently bonded with terpyridine ligands.

A terpyridine ligand is covalently linked to a hexamolybdate cluster through the Mo-N imido bond, paving the way for the preparation of hybrids containing covalently bonded transition metal complexes and polyoxometalate clusters.

Hybrid Molecular Materials Based on Covalently Linked Inorganic Polyoxometalates and Organic Conjugated Systems.

The Mo≡N bond is conjugated with the organic segment in the novel molecular organic-inorganic hybrid materials that have been obtained by Pd-catalyzed coupling of an iodo-functionalized hexamolybdate anion and an alkyne (see scheme; Ar=4-methylphenyl,3-5-di(tert-butyl)phenyl). The interaction between the polyoxometalate cluster and the organic conjugated system is particularly apparent from the strong red-shifted absorption in the UV/Vis spectrum.
