Electrolyte and fluid transport in the kidney are regulated in part by arachidonic acid and its metabolites. 17-HETE is a cytochrome P450 (CYP450) metabolite of arachidonic acid that has stereospecific effects on sodium transport in the kidney.17(S)-HETE inhibits proximal tubule ATPase activity by as much as 70% at a concentration of 2 µM.
17(S)-HETE is arachidonic acid metabolite through cytochrome P-450 pathways. 17(S)-HETE serves as allosteric activator of the cytochrome P450 1B1 and inhibitor of ATPase, induces cardic hypertrophy.
