[:es]Newly discovered ‘magic methyl’ reaction could turbocharge the potency of some drugs[:]

For years, drug discovery chemists have struggled to streamline a process that can boost a drug’s potency up to 2000-fold: “magic methylation.” The reaction sweeps out single hydrogen atoms and replaces them with methyl groups—reshaping the drug molecule to more easily interact with its biological targets. But carrying out this sleight of hand is so…
