The mode of action involves cleavage within the molecular structure of the eukaryotic membrane phospholipid sphingomyelin. Normal cleavages of phospholipids are necessary housekeeping processes for maintenance of healthy tissues, but when abnormal, wholesale cleavages occur in sphingomyelin, specifically between the choline and phosphate junction–i.e., at the D site–the result is actual tissue necrosis, or cell death.
