We prepared amide compounds which were derived from ferulic acid using various amines, and investigated their stimulatory effects on insulin secretion using rat pancreatic RIN-5F cells. Most of these compounds exhibited significant promotion of the insulin-release at a concentration of 10 muM and in particular, the amides having n-butyl, n-pentyl, pyrrolidine, and piperidine groups showed high activity.

In Silico Design and Enantioselective Synthesis of Functionalized Monocyclic 3‐Amino‐1‐carboxymethyl‐β‐lactams as Inhibitors of Penicillin‐Binding Proteins of Resistant Bacteria
novel class of monocyclic 3‐amino‐β‐lactams to inhibit penicillin‐bindingproteins (PBPs) of various (resistant) bacteria was assessed, revealing the potential of α‐benzylidenecarboxylates as interesting leads in the pursuit of novel PBP inhibitors. No deactivation by representative enzymes belonging to the four β‐lactamase classes was observed, while weak inhibition of class C β‐lactamase P99 was demonstrated
