Use of synthetic fluorescent ceramide molecules allows the discovery of the first selective drug-like smallmoleculeinhibitors for alkaline ceramidase 3, an intra-membrane enzyme involved in sphingolipid metabolism in health and disease. These inhibitors represent a new paradigm for controlling lipid metabolism with drug-like smallmolecules targeting conformationally dynamic membrane proteins.
This study explored the potential of a series of PZM21 analogues for pain treatment. Specifically, the hydroxyphenyl ring of PZM21 was replaced with a naphthyl ring, the thienyl ring was substituted with either a phenyl ring or furan rings, and the essential dimethylamine and urea groups were retained. These compounds aimed to enhance safety and minimize the adverse effects associated with opioid drugs
