Mycophenolic acid (MPA) has been previously reported as an inhibitor of the chikugunya virus (CHIKV) with an EC50 value of 0.2 μM. We used MPA as a lead compound designing and synthesizing a series of isatins and benzolactones in a typical medicinal chemistry program. The synthesis and testing of 19 derivatives produced compounds with no desired activity which prompted us to retest the lead compound, MPA. We can reveal that MPA shows no anti-CHIKV activity and therefore needs to be reassessed as a lead compound for this target.

Deactivation of heterogeneous hydrogenation catalysts by alcoholic solvents

Hydrogenations using supported metal catalysts are ubiquitous in organic chemistry; yet often times there is a lack of knowledge of key subtle mechanistic features of these reactions that can spell the difference between success or failure in a given synthetic application. Herein we detail an unexpected deactivation of certain heterogeneous hydrogenation catalysts caused by the typical solvent of choice for such reactions, simple aliphatic alcohols. This phenomenon was found to be general for several classes of substrates using either Raney Ni or supported Pd-catalysts. The characteristics of this phenomenon, including the reversibility of the catalyst deactivation upon exposure to air, are consistent with literature reports of alcohol decomposition on metal surfaces forming adsorbed CO.
