| Targets |
L-NIL HCl targets inducible nitric oxide synthase (iNOS), an enzyme that catalyzes the production of nitric oxide (NO) from L-arginine. iNOS is induced by inflammatory stimuli such as LPS and cytokines and produces large amounts of NO that contribute to inflammation and tissue damage. By selectively inhibiting iNOS, L-NIL HCl reduces the production of NO in inflammatory conditions. The compound shows selectivity for iNOS over eNOS and nNOS, which are constitutively expressed and have important physiological functions.

| ln Vitro |
L-NIL is significantly more effective in inhibiting mouse inducible NOS (miNOS) than rat brain constitutive NOS (rcNOS), and it does so in a concentration-dependent manner. According to the IC50 values of 3.3 and 92 pM for L-NIL with miNOS and rcNOS, respectively, L-NIL is 28 times more selective for miNOS. Furthermore, compared to L-NMA or L-NNA, L-NIL has a roughly 6-fold higher efficacy for miNOS[2].
In vitro, L-NIL HCl is a relatively selective inhibitor of iNOS with IC50 values of 0.4-3.3 µM for iNOS, 8-38 µM for eNOS, and 17-92 µM for nNOS. It effectively inhibits iNOS activity in cell-based assays. The compound's ability to inhibit iNOS has been confirmed in various cell types stimulated with LPS or inflammatory cytokines. L-NIL HCl has anti-inflammatory activity through the reduction of NO production. |
| ln Vivo |
In mice with renal IR, L-NIL (10 and 30 mg/kg, IP) inhibits autophagy, oxidative stress, and inflammation[1].
In vivo, L-NIL HCl effectively inhibits iNOS activity and has been used to demonstrate a critical role for iNOS in the immune response to infection by the protozoan L. major. It has anti-inflammatory activity in animal models. However, specific in vivo efficacy data in animal models are not extensively detailed in the available literature. The compound is a research tool for studying the role of iNOS in inflammation and immune responses. |
| Enzyme Assay |
In vitro enzyme/receptor binding assays for L-NIL HCl are iNOS inhibition assays using purified iNOS, eNOS, and nNOS enzymes. Each enzyme is incubated with L-arginine and cofactors in the presence of varying concentrations of L-NIL HCl, and the production of nitric oxide (NO) is measured using the Griess assay or chemiluminescence. The IC50 for inhibition of each NOS isoform is determined from dose-response curves.
|
| Cell Assay |
In vitro cellular assays for L-NIL HCl are performed using macrophages (RAW 264.7) or other cell types that express iNOS upon stimulation. Cells are treated with L-NIL HCl and stimulated with LPS or IFN-γ. Nitric oxide production is measured by the Griess assay. iNOS expression is assessed by Western blotting or quantitative PCR. Cell viability is evaluated using MTT assays to ensure that the observed inhibition of NO production is not due to cytotoxicity.

| Animal Protocol |
Animal/Disease Models: Adult male Balb/c (20-25 g)[1].
Doses: 10 and 30 mg/kg. Route of Administration: Intraperitoneally at the end of CLP and at 6 h after sepsis induction. Experimental Results: Led to a negligible increase in plasma NGAL compared to sham mice. Led to a significant decrease in both TLR4 and IL1β Protein contents and clusterin transcript. demonstrated an increase in NFAT5 mRNA levels, as compared with mice treated with vehicle. Promoted a decrease in AR protein expression, as compared with animals treated with vehicle. In vivo animal experiments for L-NIL HCl are conducted in rodent models of inflammation and infection. Mice are administered L-NIL HCl via oral or intraperitoneal injection, and inflammatory markers or pathogen load are assessed. In models of L. major infection, L-NIL HCl has been used to demonstrate a critical role for iNOS in the immune response. However, detailed protocols are not extensively documented in the available literature. |
| ADME/Pharmacokinetics |
L-NIL HCl has a molecular weight of 260.16 g/mol and a molecular formula of C8H19Cl2N3O2. It is a relatively selective iNOS inhibitor. The compound should be stored under recommended conditions. Detailed pharmacokinetic parameters such as half-life, Cmax, and bioavailability have not been extensively reported. As a research compound, L-NIL HCl is primarily used in in vitro and in vivo studies.
|
| Toxicity/Toxicokinetics |
The toxicological profile of L-NIL HCl has not been extensively characterized. As an iNOS inhibitor, the compound may have potential effects on immune function and NO-mediated physiological processes. No significant toxicity has been reported in the available literature. Standard toxicology studies would be necessary to establish its safety profile. The compound is a research tool and is not intended for human use.
