eNOS Inhibitor

eNOS Inhibitors (12):

Cat. No. Product Name Effect Purity
  • HY-18732A
    L-NMMA acetate
    		Inhibitor ≥99.0%
    L-NMMA acetate is a nitric oxide synthase inhibitor of all NOS isoforms including NOS1, NOS2, and NOS3. The Ki values for nNOS (rat), eNOS (human), and iNOS (mouse) are approximately 0.18, 0.4, and 6 μM, respectively.
  • HY-100986
    L-NIO dihydrochloride
    		Inhibitor
    L-NIO dihydrochloride is a potent, non-selective and NADPH-dependent nitric oxide synthase (NOS) inhibitor, with Kis of 1.7, 3.9, 3.9 μM for neuronal (nNOS), endothelial (eNOS), and inducible (iNOS), respectively. L-NIO dihydrochloride induces a consistentfocal ischemic infarctin rats.
  • HY-P3168
    Martentoxin
    		Inhibitor
    Martentoxin, a 4,046 Da polypeptide toxin, is a large-conductance Ca2+-activated K+ (BKCa) channel inhibitor. Martentoxin attenuates NO release, inhibits iNOS activation and upregulates eNOS mRNA expression in HUVECs induced by TNF-α. Martentoxin can be used for vascular diseases research.
  • HY-176779
    Guanidino ethyl disulfide
    		Inhibitor
    Guanidino ethyl disulfide (GED) (Compound 23) is a NO Synthase (NOS) inhibitor with EC50s of 110, 630 and 180  μM for iNOS, eNOS and bNOS, respectivly. Guanidino ethyl disulfide effectively inhibits nitrite production in J774.2 macrophages. Guanidino ethyl disulfide can be used for circulatory shock, inflammation and neurological diseases research.
  • HY-125740
    Malvidin-3-glucoside chloride
    		Inhibitor 99.87%
    Malvidin-3-glucoside (Malvidin-3-O-glucoside; Oenin) chloride is an orally active inhibitor of the NF-κB pathway, which blocks inflammatory responses induced by TNF-α, reduces IκB-α degradation and p65 nuclear translocation, and upregulates endothelial nitric oxide synthase eNOS to increase NO production. Malvidin-3-glucoside chloride exerts anti-inflammatory and antioxidant effects by inhibiting pro-inflammatory molecules such as MCP-1, ICAM-1, and IL-6, and regulating intestinal microorganisms and metabolites, while protecting endothelial cells and improving intestinal microecological dysbiosis under inflammatory conditions. Malvidin-3-glucoside chloride can be used to study chronic inflammatory-related diseases such as atherosclerosis and inflammatory bowel disease, and has the potential to prevent vascular inflammation and improve intestinal health.
  • HY-W003969
    Aminopicoline
    		Inhibitor 99.99%
    Aminopicoline (Ascensil) is a potent and nonselective inhibitor of NO synthase (NOS) isoenzymes (iNOS, nNOS, eNOS).
  • HY-W022047
    nNOS-IN-1
    		Inhibitor 99.53%
    nNOS-IN-1(Compound 14) is an inhibitor for nitric oxide synthases (NOS), that exhibits inhibitory activities against neuroal, inducible and endothelial NOS, with IC50s of 2.5, 5.7 and 13 μM, respectively.
  • HY-135224
    1,4-PBIT dihydrobromide
    		Inhibitor ≥98.0%
    1,4-PBIT (1,4-PB-ITU) dihydrobromide (compound 46) is a potent nitric oxide synthases (NOS) inhibitor, with Ki values of 7.6 nM, 360 nM, and 16 nM for the inducible (iNOS), endothelial (eNOS), and neuronal (nNOS) isozymes, respectively.
  • HY-152536
    iNOS inhibitor-10
    		Inhibitor
    iNOS inhibitor-10 is an iNOS inhibitor (IC50: 65 nM). iNOS inhibitor-10 has antiproliferative effect against triple negative breast cancer cells.

    		Inhibitor
    hnNOS-IN-3 (compound 39) is a selective nNOS inhibitor, with a Ki of 0.32 μM. The nNOS binding of hnNOS-IN-3 is competitive with L-arginine. The selectivity of hnNOS-IN-3 for nNOS versus iNOS (Ki=37 μM) and eNOS (Ki=9.4 μM) is 115-fold and 29-fold, respectively.
  • HY-125740R
    Malvidin-3-glucoside chloride (Standard)
    		Inhibitor
    Malvidin-3-glucoside (Malvidin-3-O-glucoside; Oenin) chloride (Standard) is the analytical standard of Malvidin-3-glucoside chloride (HY-125740).
