Biochem/physiol Actions

HET0016 is a potent and selective inhibitor against cytochrome P450 (CYP450) ω-hydroxylases (human CYP4A11/4A22/4F2/4F3, rat CYP4A1/4A2/4A3/4A8)-mediated 20-hydroxyeicosatetraenoic acid (20-HETE) biosynthesis (IC50 = 8.9/35 nM using human/rat renal microsomes), exhibiting much reduced potency against epoxyeicosatrienoic acids (EETs) biosynthesis (IC50 = 2.8 μM/rat microsome) or the enzyme activities of CYP2C9/2D6/3A4 and COX (IC50 = 3.3/83.9/71 μM and 2.3 μM). HET0016 is widely employed both in cultures (1-10 μM) and in aminals in vivo (1-10 mg/kg via i.v., i.m., i.p. or s.c.) for probing 20-HETE-dependent physiological and pathological processes.

The present study examined the inhibitory effects of N-hydroxy-N'-(4-butyl-2-methylphenyl)-formamidine (HET0016) on the renal metabolism of arachidonic acid by cytochrome P450 (CYP) enzymes. HET0016 exhibited a high degree of selectivity in inhibiting the formation of 20-hydroxy-5,8,11,14-eicosatetraenoic acid (20-HETE) in rat renal

Cytochrome P450s enzymes catalyze the metabolism of arachidonic acid to epoxyeicosatrienoic acids (EETs), dihydroxyeicosatetraenoic acid and hydroxyeicosatetraeonic acid (HETEs). 20-HETE is a vasoconstrictor that depolarizes vascular smooth muscle cells by blocking K+ channels. EETs serve as endothelial derived hyperpolarizing factors.

20-HETE, an arachidonic acid metabolite synthesized by cytochrome P450 4A, plays an important role in acute brain damage from ischemic stroke or subarachnoid hemorrhage. We tested the hypothesis that 20-HETE inhibition has a protective effect after intracerebral hemorrhage (ICH) and

Contribution of salt wasting and volume depletion to the pathogenesis of hypercalciuria and hyperphosphaturia is poorly understood. Pendrin/NCC double KO (pendrin/NCC-dKO) mice display severe salt wasting under basal conditions and develop profound volume depletion, prerenal renal failure, and metabolic alkalosis

Prostaglandins & other lipid mediators, 134, 123-130 (2017-08-16)
We previously found that 20-hydroxyeicosatetraeonic acid (20-HETE) showed an effect on proteasome activity in cytochrome P450 F2 (CYP4F2) transgenic mice. Proteasome subunit β5 (PSMB5) is a primary subunit of the proteasome. In the current study, we examine whether 20-HETE has
