nNOS Inhibitor

nNOS Inhibitors (10):

Cat. No. Product Name Effect Purity
  • HY-18732A
    L-NMMA acetate
    		Inhibitor 98.58%
    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-N6607
    Tryptanthrin
    		Inhibitor 99.89%
    Tryptanthrin is an indole quinazoline that could be an alkaloid from indigo-bearing plants. Tryptanthrin is a potent and orally active cellular Leukotriene (LT) biosynthesis inhibitor. Tryptanthrin has anticancer activity. Tryptanthrin suppresses the expression levels of NOS1, COX-2, and NF-κB and regulates the expression levels of IL-2, IL-10, and TNF-α.
  • HY-P0117A
    Tat-NR2B9c TFA
    		Inhibitor 99.67%
    Tat-NR2B9c TFA (Tat-NR2Bct TFA) is a postsynaptic density-95 (PSD-95) inhibitor, with EC50 values of 6.7 nM and 670 nM for PSD-95d2 (PSD-95 PDZ domain 2) and PSD-95d1, respectively. Tat-NR2B9c TFA disrupts the PSD-95/NMDAR interaction, inhibiting NR2A and NR2B binding to PSD-95 with IC50 values of 0.5 μM and 8 μM, respectively. Tat-NR2B9c TFA also inhibits neuronal nitric oxide synthase (nNOS)/PSD-95 interaction, and possesses neuroprotective efficacy.
  • HY-P0117
    Tat-NR2B9c
    		Inhibitor 99.97%
    Tat-NR2B9c (Tat-NR2Bct; NA-1) is a postsynaptic density-95 (PSD-95) inhibitor, with EC50 values of 6.7 nM and 670 nM for PSD-95d2 (PSD-95 PDZ domain 2) and PSD-95d1, respectively. Tat-NR2B9c disrupts the PSD-95/NMDAR interaction, inhibiting NR2A and NR2B binding to PSD-95 with IC50 values of 0.5 μM and 8 μM, respectively. Tat-NR2B9c also inhibits neuronal nitric oxide synthase (nNOS)/PSD-95 interaction, and possesses neuroprotective efficacy.
  • HY-W484263
    hnNOS-IN-3
    		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-115410
    NG-Amino-L-arginine hydrochloride
    		Inhibitor
    NG-Amino-L-arginine hydrochloride induces inactivation of the citrulline-forming activity of the nNOS, iNOS, and eNOS isoforms with Ki values of 0.3 μM, 3 μM, and 2.5 μM, respectively.
  • HY-P0184A
    Camstatin TFA
    		Inhibitor
    Camstatin TFA, a functionally active 25-residue fragment of PEP-19's IQ motif, binds calmodulin and inhibits neuronal nitric oxide (NO) synthase.
  • HY-115916
    NOS-IN-2
    		Inhibitor
    NOS-IN-2 (Compound 4i) is a potent, selective, imidamide derived NOS inhibitor with an IC50 against iNOS of 20 µM, without inhibiting eNOS. NOS-IN-2 has little toxicity and can be used for studying inflammatory disorders.
  • HY-135224
    1,4-PBIT dihydrobromide
    		Inhibitor
    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-115917
    NOS-IN-3
    		Inhibitor
    NOS-IN-3 (Compound 9a) is a potent, selective, imidamide derived NOS inhibitor with an IC50 against iNOS of 4.6 μM, without inhibiting eNOS. NOS-IN-3 has little toxicity and can be studied in the research of inducible isoform involved diseases, such as septic shock.
