oligomethylene chains terminated for the most part by charged 3,5-dimethylpyridinium (PY(+)) and/or neutral 3,5-dimethylphenyl (PH) groups, are reported. The complexes were obtained by treating equimolar amounts of the CBPQT(4+) ring and the dumbbells containing BIPY(2+) units with zinc dust in acetonitrile solutions. Whereas UV-Vis-NIR spectra revealed absorptionbands centered on ca. 1100 nm with quite different
A cobalt-catalyzed highly (Z)-selective semihydrogenation of alkynes using molecular H2 was developed using commercially available and cheap cobalt precursors. A variety of (Z)-alkenes were obtained in moderate to excellent selectivities...
Provided is a novel amine compound represented by the following formula (I) having a superior peripheral blood lymphocyte decreasing action and superior in the immunosuppressive action, rejection suppressive action and the like, which shows decreased side effects of, for example, bradycardia and the like, or a pharmaceutically acceptable acid addition salt thereof, or a hydrate thereof, or a solvate thereof.
wherein each symbol is as defined in the specification.
The invention relates to a method for synthesising tethered ruthenium catalysts and novel tethered ruthenium catalysts obtainable by this methods. The method involves carrying out an “arene swapping” reaction avoiding the requirement to use complicated techniques making use of unreliable Birch reductions and unstable cyclodienyl intermediates.

52b inhibited protein synthesis in cancer cells. Moreover, 52b significantly prevented tumor growth in a human non-small-cell lung cancer (NCI-H522) xenograft mouse model with no observable toxic effects. These findings are the first report of the synthetic compound 52b with a 1,4-benzodiazepine-2,5-dione skeleton that acts as a potentialprotein synthesis inhibitor to effectively inhibit tumor growth
