In recent years, channels that mediate store-operated calcium entry (SOCE, ie, the ability of
cells to sense a decrease in endoplasmic reticulum luminal calcium and induce calcium
entry across the plasma membrane) have been associated with a number of disorders,
spanning from immune disorders to acute pancreatitis and have been suggested to be
druggable targets. In the present contribution, we exploited the click chemistry approach to

In recent years, channels that mediate store-operated calcium entry (SOCE, i.e., the ability of cells to sense a decrease in endoplasmic reticulum luminal calcium and induce calcium entry across the plasma membrane) have been associated with a number of disorders, spanning from immune disorders to acute pancreatitis and have been suggested to be druggable targets. In the present contribution, we exploited the click chemistry approach to synthesize a class of SOCE modulators where the arylamide substructure that characterizes most inhibitors so far described is substituted by a 1,4-disubstituted 1,2,3-triazole ring. Within this series, inhibitors of SOCE were identified and the best compound proved effective in an animal model of acute pancreatitis, a disease characterized by a hyperactivation of SOCE. Strikingly, two enhancers of the process were discovered, affording invaluable research tools to further explore the (patho)physiological role of capacitative calcium entry.
