Simple, Chemoselective Hydrogenation with Thermodynamic Stereocontrol
摘要:
Few methods permit the hydrogenation of alkenes to a thermodynamically favored configuration when steric effects dictate the alternative trajectory of hydrogen delivery. Dissolving metal reduction achieves this control, but with extremely low functional group tolerance. Here we demonstrate a catalytic hydrogenation of alkenes that affords the thermodynamic alkane products with remarkably broad functional group compatibility and rapid reaction rates at standard temperature and pressure.

Singly and multiply charged imidazolium cations (ICs) have been identified as a class of chemical compositions that possess potent antineoplastic, antibacterial and antimicrobial properties. The imidazolium cations disclosed demonstrate greater or equivalent potency towards cancerous cells as the current clinical standard, cisplatin. These imidazolium cations, however, achieve this efficacy without any of the known toxic side effects caused by heavy metal-based antineoplastic drugs such as cisplati.

The anti-tumor activity of imidazolium salts is highly dependent upon the substituents on the nitrogen atoms of the imidazolium cation. We have synthesized and characterized a series of naphthalene-substituted imidazolium salts and tested them against a variety of non-small-cell lung cancer cell lines. Several of these complexes displayed anticancer activity comparable to cisplatin. These compounds induced apoptosis in the NCI-H460 cell line as determined by Annexin V staining, caspase-3, and PARP cleavage. These results strongly suggest that this class of compounds can serve as potent chemotherapeutic agents.
