LX-3 is a selective activator of the p38 mitogen-activated protein kinase (MAPK) pathway, which de-represses a subset of endogenous genes repressed by DNA methylation.
BLX3887 is an inhibitor of 15-lipoxygenase type 1 (15-LO-1; IC50 = 32 nM in a cell-free enzyme assay).1 It is selective for 15-LO-1 over 15-LO-2, which it does not inhibit, 5-LO (IC50 = 472 nM), and 12-LO (IC50 = 3,310 nM). BLX3887 inhibits the production of 15-LO metabolites selectively in eosinophils over neutrophils when used at a concentration of 10 μM. It also inhibits endocytosis in, and the migration of, isolated human peripheral blood mononuclear cell-derived dendritic cells in vitro. |1. Archambault, A.-S., Turcotte, C., Martin, C., et al.

C18 dihydro Ceramide is a bioactive sphingolipid and precursor in the de novo synthesis of C18 ceramide that lacks the 4,5-trans double bond. [1] Increased C18 dihydroceramide lipid levels lead to increased triacylglycerol storage and autophagosome accumulation as well as upregulation of the fibrosis markers α-SMA and FGF2 in Chang and LX-2 liver cells. C18 dihydro Ceramide is elevated in the plasma of pre-diabetics up to 9 years prior to the onset of type 2 diabetes. [2] It is also elevated in the skin of patients with lesional atopic dermatitis.[3]
