the first committed step of cholesterol biosynthesis is catalyzed by squalenesynthase, we explored whether inhibiting this enzyme protected cells against cholesterol‐dependent cytolysins. We first synthesized 22 different nitrogen‐containing bisphosphonate molecules that were designed to inhibitsqualenesynthase. Squalenesynthase inhibition was quantified using a cell‐free enzyme assay, and validated
The preparation of N-substituted aminomethylidenebisphosphonates and their tetraalkyl esters via reaction of isonitriles with trialkyl phosphites and hydrogen chloride. Part 1
The reaction of isonitriles with trialkyl phosphites in the presence of hydrogen chloride gives tetraalkyl N-substituted aminomethylidenebisphosphonates via N-methylideneaminium (isonitrilium) salts. Hydrolysis or dealkylation of these tetraalkyl esters gives N-substituted aminomethylidenebisphosphonic acids in high yields.
