Sphingolipid biosynthesis inhibitor
Molecular Weight:
102.09
Purity:
98% by TLC, NMR (Conforms)
Form:
White solid
CAS Number:
[339-72-0]
Formula:
C3H6N2O2
Application Notes:
L-Cycloserine down-regulates sphingolipid biosynthesis via inhibition of serine palmitoyltransferase (3-ketodihydrosphingosine synthetase).1 The L isomer was shown to be 100-fold more potent than the D isomer at inhibition of the brain microsomal enzyme.1 It is a useful pharmacological agent for lowering sphingolipid levels in cells2 as well as in animal models3. Inhibition of de novo ceramide biosynthesis with L-cycloserine positively affected the senescent phenotype, restoring neuronal signaling and reducing mitochondrial dysfunction in a cortical neuronal model of senescence.4
