serine-palmitoyl-transferase (spt)

Myriocin (Thermozymocidin), a metabolite derived from Myriococcum albomyces, is a serine-palmitoyltransferase (SPT) inhibitor with potential antitumour, anticancer, and antiparasitic activities.Myriocin inhibits tumour growth by regulating macrophage polarisation and function through the PI3K/Akt/mTOR pathway.Myriocin inhibits HCV infection and can be used in the study of neurological diseases. Myriocin inhibits HCV infection and can be used to study neuropathy and fungal infections.

SPT-IN-1 (compound 1) is an orally active and highly potent inhibitor of serine palmitoyl transferase (SPT) with an IC50 value of 5.19 nM against human SPT1, SPT-IN-1 is utilized in metabolic disease research to explore sphingolipid biosynthesis regulation, insulin resistance mechanisms, and therapeutic strategies for type 2 diabetes and dyslipidemia.

3-Keto Sphinganine (d12:0) is a short-chain analog of 3-keto sphinganine (d18:0), which typically possesses a C18 chain length. The latter is a lyso-sphingolipid synthesized through the condensation of L-serine and palmitoyl-CoA mediated by the enzyme serine palmitoyl transferase (SPT). A deficiency in Vitamin K deactivates SPT, leading to a reduced synthesis of 3-keto sphinganine among other sphingolipids. [Matreya, LLC. Catalog No. 1893]
