d-threo sphinganine

D-threo Sphinganine (d18:0) is a synthetic bioactive sphingolipid and stereoisomer of sphinganine (d18:0) and L-erythro sphinganine (d18:0) . It induces autophagy in HCT116 cells when used at a concentration of 12 μM. D-threo Sphinganine (d18:0) is metabolized via sphinganine N-acyltransferase and sphinganine kinase in vivo in rat liver.

DL-erythro/threo Sphinganine (d16:0) is a sphingolipid that is decreased in rats following long-term, low-dose administration of dimethoate and is used as a biomarker for dimethoate exposure. It has been found in the fermentation broth of Bacterium SRCnm, which has antimicrobial and antioxidant activities. This product is a mixture of sphinganine (d16:0), L-erythro sphinganine (d16:0), D-threo sphinganine (d16:0), and L-threo sphinganine (d16:0).
