Disease relevance of octadec-17-ynoic acid

  • However, after partial blockade of cytochrome P-450 4A enzymes with 17-octadecynoic acid (17-ODYA), hypoxia increased the diameter by 65 +/- 6 micrometer (P < 0.05) [1].

High impact information on octadec-17-ynoic acid

  • Microiontophoresis of ACh evoked vasodilation that conducted along arterioles; the local (direct) response was inhibited by N(omega)-nitro-L-arginine (LNA), and both local and conducted responses were inhibited by 17-octadecynoic acid (17-ODYA) [2].
  • High sensitivity toward the specific P450 inhibitor 17-octadecynoic acid suggested that omega-hydroxylation of VLCFAs is catalyzed by P450 enzymes belonging to the CYP4A/F subfamilies [3].
  • In contrast, we observed that CYP450 inhibitors such as SKF-525A, 17-octadecynoic acid, 1-aminobenzotriazole, and 6-(2-propargyloxyphenyl)hexanoic acid reduced 12(S)-HETE levels, 3T6 fibroblast growth, and DNA synthesis induced by FBS [4].
  • The high sensitivity toward the more specific cytochrome P450 inhibitors ketoconazole and 17-octadecynoic acid suggests that hydroxylation of C22:0 and omega-hydroxy-C22:0 may be catalyzed by one or more cytochrome P450 hydroxylases belonging to the CYP4A and/or CYP4F subfamily [5].
  • Carbenoxolone, a gap junction inhibitor, significantly attenuated the SLIGRL-amide-evoked, EDHF-dependent relaxation, although neither 17-octadecynoic acid, a P450 epoxygenase inhibitor, nor catalase, a hydrogen peroxide scavenger, revealed inhibitory effects [6].

Biological context of octadec-17-ynoic acid

  • Enzyme inactivation by 17-octadecynoic acid and 16-hydroxy-17-octadecynoic acid is due to alkylation of the prosthetic heme group to given an adduct tentatively identified as N-(2-oxo-3-hydroxy-17-carboxyheptadecyl)protoporphyrin IX by its chromatographic and spectroscopic properties [7].
  • This study examined whether cortical or papillary blood flow is altered after removal of the clip from the renal artery of 1-K,1C hypertensive rats, and the effects of blockade of the renal metabolism of arachidonic acid by P-450 with 17-octadecynoic acid (17-ODYA) on the fall in blood pressure [8].

Anatomical context of octadec-17-ynoic acid


Associations of octadec-17-ynoic acid with other chemical compounds

  • Miconazole (10 microM) or 17-octadecynoic acid (17-ODYA; 10 microM) diminished local vasodilation by 15-20% and conducted responses by 50-70% (P < 0.05), suggesting a role for cytochrome P-450 (CYP) metabolites in arteriolar responses to ACh [12].
  • This ACh-induced relaxation was inhibited and converted to constriction by catalase (-53 +/- 10%, n = 6) or KCl (-30 +/- 3%, n = 7), whereas 17-octadecynoic acid and 6-(2-propargylloxyphenyl) hexanoic acid, two inhibitors of cytochrome P450 monooxygenase, had no significant effect (3 +/- 1% and 20 +/- 8%, n = 5, respectively) [13].
  • The cytochrome P-450 monooxygenase inhibitor 17-octadecynoic acid (17-ODYA) and the protein kinase C inhibitor staurosporine both significantly attenuated the effects of fenoldopam by 67% [14].
  • In contrast, 17-octadecynoic acid (17-ODYA; 10(-5) M), a suicide-substrate inhibitor of renal cytochrome P450 omega-hydroxylase, completely blocked the transport response to bradykinin, while the cyclooxygenase inhibitor sodium meclofenamate (10(-5) M) had no effect [15].
  • The endothelium removal but not the inhibition of prostanoid synthesis with either 10 microM indomethacin or 10 microM 17-octadecynoic acid potentiated the contractions to noradrenaline and to KCl both under control conditions as well as after the chronic in vivo administration of L-NAME [16].

Gene context of octadec-17-ynoic acid


Analytical, diagnostic and therapeutic context of octadec-17-ynoic acid

  • Administration of 17-octadecynoic acid (17-ODYA), which is a P450 4A inhibitor, attenuated the constriction of third-order cremasteric arterioles in response to elevation of superfusion solution PO2 from approximately equal to 3 to 5 mm Hg to approximately equal to 35 mm Hg [20].
