PR280 is a potent inhibitor of dihydroceramide desaturase 1 (Des1) with an IC50 of 700 nM. It forms hydrogen bonds with amino acid residues of Des1, while its cyclopropenone group may coordinate with the iron center, stabilizing its binding at Des1s active site. This inhibits the ceramide biosynthesis pathway, preventing dihydroceramide (dhCer) from converting into ceramide. PR280 can be used in research related to sphingolipid metabolism disorders, including cancer and metabolic diseases.
