Biochem/physiol Actions

17-Octadecynoic acid (7-ODYA) is an irreversible inhibitor of cytochrome P450 isozymes, that participates in long-chain fatty acid metabolism.
Suicide substrate inhibitor that selectively and irreversibly inhibits cytochrome P450 epoxygenases and ω-hydrolases.

The endothelium plays an important role in maintaining vascular homeostasis by synthesizing and releasing several mediators of vasodilation, which include prostacyclin (PGI(2)), nitric oxide, and endothelium-derived hyperpolarizing factor (EDHF). We have recently defined the role of nitric oxide and PGI(2)

We characterized the inhibitory activity of several acetylenic and olefinic compounds on cytochrome P450 (CYP)-derived arachidonic acid omega-hydroxylation and epoxidation using rat renal cortical microsomes and recombinant CYP proteins. Among the acetylenic compounds, 6-(2-propargyloxyphenyl)hexanoic acid (PPOH) and N-methylsulfonyl-6-(2-propargyloxyphenyl)hexanamide were found

Protein fatty-acylation is the covalent addition of a lipid chain at specific amino acids. This modification changes the inherent hydrophobicity of a protein, often targeting it to cellular membrane compartments. Acylation may also regulate protein activity, stability, and protein-protein interactions.
