B12‐Cofactor Inactivation by Cobalt to Rhodium Mutation in Methylrhodibalamin: An Antivitamin B12 and Antibiotic

open access: yesChemistryEurope, EarlyView.
Replacement of cobalt in the organometallic B12‐cofactor methylcobalamin (MeCbl) by rhodium furnishes a structural mimic with a significantly stronger metal–carbon bond. This synthetically challenging formal metal‐mutation converts the naturally optimized biological methyl‐transfer catalyst MeCbl into a designed antivitamin B12, an inactivated B12 ...

Development of CPA‐Catalyzed β‐Selective Reductive Amination of Cardenolides for the Synthesis and Biological Evaluation of Hydrolytically Stable Analogs

open access: yesChemistry – A European Journal, EarlyView.
We describe a new method to produce hydrolytically stable cardiotonic steroids using a CPA‐controlled diastereoselective reductive amination of cardenolide aglycones. The oleandrin and digitoxigenin analogs exhibited promising activity against various cancer cell lines in the NCI‐60 screen.
