substituents representative of the naturally occurring sphingolipid families. The screening on mammalian sphingomyelin synthase (SMS) and glucosylceramide synthase (GCS) and yeast inositol phosphorylceramide synthase (IPCS) enzymes identified several inhibitors of GCS and IPCS, but no inhibition of SMS was observed among the tested compounds.
