Two new polyoxovanadate clusters templated through cysteamine

Surface properties of water-soluble glycine-cysteamine-protected gold clusters.

We report the synthesis of water-soluble, nearly monodisperse glycine-cysteamine (Gly-CSA) gold monolayer protected clusters (MPCs) via base deprotection of Fmoc-Gly-CSA MPCs. The resulting Gly-CSA MPCs, which have terminal primary amine groups, are fully characterized by (1)H and (13)C NMR, UV-vis spectroscopy, and TEM, and their surface properties were probed by dynamic light scattering and a...

Two birds with one stone: anion templated ball-shaped Ag56 and disc-like Ag20 clusters.

One-pot reaction of AgSBu(t) and AgOAc in the methanol-ethanol-DMF solvent system under room temperature gave a ball-shaped Ag56 cluster and a disc-like Ag20 cluster. The formations of clusters and are templated by an in situ generated S(2-) ion from the cleavage of the S-C bond of SBu(t) and CO3(2-) ion from the fixation of atmospheric carbon dioxide, respectively. Interestingly, cluster 1 onl...

Evaluation of Two BSP Libraries through Parallel Sorting on Clusters

Old and New Neuroendocrine Molecules: Somatostatin, Cysteamine, Pantethine and Kynurenine.

The aim of this review is to commemorate Hans Selye, endocrinologist, the most famous researchers of stress and to briefly summarize the major features of somatostatin (SST), cysteamine (CysA) and patethine (PAN) in neuroendocrinological aspect, which are closely related to his scientific work. In addition, some metabolites of kynurenine pathway (KP) were also mentioned in this paper, as new, p...

Construction of anti-parallel G-quadruplexes through sequential templated click.

Biologically relevant DNA sequences were assembled onto addressable cyclopeptide scaffolds through sequential oxime and CuAAc reactions. The resulting conjugates are able to fold into well-defined anti-parallel DNA G-quadruplex structures, which exhibit high stability and reduced polymorphism.
