What was measured
Whether small molecules protect desmoplakin protein from trypsin and calpain digestion in vitro, plus computational docking and molecular dynamics

What the authors reported

Several molecules, including sodium dodecyl sulfate, palmitoylethanolamide, GW0742, salirasib, eprosartan mesylate and GSK1838705A, prevented degradation of wild-type and disease-variant desmoplakin by trypsin and calpain without changing protease activity. Computational screening did not predict which molecules would work. Simulations suggest long hydrophobic molecules can sit in a groove beside the cleavage site.

Limits of this study

A test-tube protein study; it cannot show effect in people or animals. PEA was one of many hits and no concentration is given in the abstract. The authors declare no conflict of interest and state funders had no role.
