    D-erythro-2-myristoylamino-1-phenyl-1-propanol (D-MAPP) is an inhibitor of alkaline ceramidase due to it being structurally similar to ceramide. D-erythro-MAPP has the opposite stereochemical configuration of natural D-erythroceramides which causes it to inhibit alkaline ceramidase. D-MAPP is also a poor inhibitor of acid ceramidase. The L-erythro- MAPP isomer is inactive towards ceramidase due to it having the same stereochemical configuration as natural ceramides. The inhibition of ceramidase by D-MAPP causes an elevation of ceramide levels in cells leading to growth suspension and cell cycle arrest1 but not apoptosis or TNF/IFN induced cell death.2 In cancer cell lines D-MAPP and other ceramidase inhibitors have been used to increase the levels of endogenous ceramides. The higher levels of ceramides causes an increase in the apoptotic effects following radiation of the cells.3 D-MAPP and N,N-dimethyl-sphingosine inhibit mitogen-activated protein kinase activation induced by oxidized low-density lipoproteins.4
