HET0016 is a potent and selective 20-HETE synthase inhibitor [IC50s: 17.7 nM, 12.1 nM, and 20.6 nM for recombinant CYP4A1-, CYP4A2- and CYP4A3-catalyzed 20-HETE synthesis]. HET0016 is also a selective CYP450 inhibitor shown to inhibit angi.
1-Deoxysphingosine (m18:1(14Z)) is an unconventional sphingolipid featuring a (14Z) double bond at the n-4 position, synthesized when serine palmitoyltransferase combines palmitoyl-CoA with alanine, not serine, during sphingolipid production. Unlike typical sphingolipids, it lacks the essential C1-hydroxyl group for standard degradation but undergoes metabolism by cytochrome P450 (CYP) subfamilies CYP4A and CYP4F in MEF cells.
