**Molecular Mechanism and Rationale**
The molecular foundation for SMPD1 inhibition in Alzheimer's disease centers on the dysregulated sphingolipid metabolism that occurs within membrane microdomains of affected neurons. Acid sphingomyelinase (ASM/SMPD1), a lysosomal enzyme encoded by the SMPD1 gene, catalyzes the hydrolysis of sphingomyelin to ceramide and phosphorylcholine. In healthy neurons, this process is tightly regulated, but in Alzheimer's disease, ASM activity becomes pathologically e
