Several fluorescent derivatives of sphingomyelin have been synthesized and used as substrates for the acidic (lysosomal) or neutral (magnesium-dependent) sphingomyelinases of rat brain. These compounds were also successfully employed for demonstrating the deficiency of the enzyme in cells (skin fibroblasts or lymphoid cell lines) derived from patients with Niemann-Pick disease, Types A or B. The differences between the lipidotic and normal cells were demonstrated using cell extracts as well as intact, living cells “loaded” with the fluorescent sphingomyelin.
