L-NAME HClL-NAME HCl (NG-Nitroarginine methyl ester, N-Nitro-L-arginine methylester) is a nonselective inhibitor of nitric oxide synthetases (NOS) for nNOS (bovine), eNOS (human), and iNOS (murine), with Ki of 15 nM, 39 nM and 4.4 μM, respectively. |
(C) HOSS1 cells were grown in soft agar, in the presence or absence of L-NAME (10 mM), and treated as indicated with drugs, as indicated, for 6 h and 12 h. Cells were subjected to electrophoresis and stained. The tail moments of cells were measured and presented below each image (n = 4, ± SEM) *P < 0.05 less than corresponding value in vehicle-treated cells. |

Ginsenoside Rb3Ginsenoside Rb3, extracted from the plant Panax ginseng, plays important roles in cardiovascular diseases, including myocardial ischemia-reperfusion (I/R) injury. Ginsenoside Rb3 (0.1-10 μM) is tested for inhibition of tumor necrosis factor-α (TNF)-induced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) luciferase reporter activity using a human kidney 293T cell-based assay. Ginsenoside Rb3 shows the significant activity with an IC50 of 8.2 μM. Ginsenoside Rb3 also inhibits the induction of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) messenger Ribonucleic acid (mRNA) in a dose-dependent manner after HepG2 cells have been treated with TNF-α (10 ng/mL). |
