Human umbilical vascular endothelial cells (HUVECs)	1 mM	4 days	To induce endothelial-to-mesenchymal transition (EndoMT) and study its reversibility. Results showed that the combination of L-NAME and Ang II can stimulate EndoMT in HUVECs, and this process can be reversed.	Front Pharmacol. 2022 Jun 23;13:912660.
mouse aortic segments	300 µM	20 min	To evaluate the involvement of the endothelial cell layer in regulating VSMC contraction and tone, L-NAME inhibits NO production, further increasing contraction.	Int J Mol Sci. 2021 Nov 26;22(23):12812.
Fetal vessels	100 μM		In fetal vessels, L-NAME was used along with ODQ and INDO to study ACh-induced vasodilation. Results showed that ACh-induced relaxation was significantly reduced in SD fetal vessels.	Sci Rep. 2015 May 8;5:9753.
Weanling vessels	100 μM		In weanling vessels, L-NAME was used along with ODQ and INDO to study ACh-induced vasodilation. Results showed that ACh-induced relaxation was significantly reduced in SD weanling vessels.	Sci Rep. 2015 May 8;5:9753.
Adult vessels	100 μM		In adult vessels, L-NAME was used along with ODQ and INDO to study ACh-induced vasodilation. Results showed that ACh-induced relaxation was significantly reduced in SD adult vessels.	Sci Rep. 2015 May 8;5:9753.

Mice	Gastric emptying model	Intraperitoneal injection	50 mg/kg	Single dose	L-NAME significantly delayed gastric emptying, while L-Arginine was not directly used in the experiment.	Gut. 2005 Aug;54(8):1078-84
Mice	Hypertension model	Oral	0.5mg/mL	2 weeks L-NAME, 3 weeks high salt diet	To study the role of CD70 and immunological memory in hypertension	Circ Res. 2016 Apr 15;118(8):1233-43
Mice	ACE 10/10 and ACE 3/3 mice	Drinking water	0.5 mg/mL for WT mice, 1.5 mg/mL for mutant mice	4 weeks of L-NAME, 1-week washout, 3 weeks of high salt diet	To study the development of salt sensitivity following renal injury, results showed that mice lacking renal ACE did not develop hypertension after high salt diet	Hypertension. 2015 Sep;66(3):534-42
Mice	EP3 receptor deficient mice	Drinking water	0.5 mg/mL	2 weeks L-NAME, 2 weeks washout, 3 weeks high-salt diet	To investigate the role of EP3 receptors in salt-sensitive hypertension, results showed that EP3 receptor deficient mice had significantly attenuated blood pressure elevation and renal inflammation during the salt-feeding phase.	Hypertension. 2019 Dec;74(6):1507-1515
Mice	Salt-sensitive hypertension model	Drinking water	0.5 mg/mL	2 weeks L-NAME, 2 weeks washout, 3 weeks high-salt diet	To study the role of SGK1 in CD11c+ antigen-presenting cells, finding that SGK1 deletion attenuates salt-sensitive hypertension and renal inflammation.	Hypertension. 2019 Sep;74(3):555-563
Rats	Chronic constriction injury model	Intrathecal injection	100 μg/10 μL	Once daily for 5 days	L-NAME reversed the analgesic effect of HBO on neuropathic pain and decreased the expression of PKG1 mRNA and protein in the spinal dorsal horn	J Headache Pain. 2017 Dec;18(1):51
Spontaneously hypertensive rats	Spontaneously hypertensive rat model	Intraperitoneal injection	30 mg/kg	Single administration, lasting 6 hours	To investigate the effect of L-NAME on the blood pressure-lowering effect of the peptide AVFQHNCQE. The results showed that L-NAME completely abolished the antihypertensive effect of AVFQHNCQE, indicating that its antihypertensive effect is mediated by changes in endothelium-derived NO availability.	Nutrients. 2019 Jan 22;11(2):225
Wistar rats	L-NAME-induced hypertension model	Drinking water	40 mg/kg	Once daily for four weeks	To investigate the changes in cardiac function and the renin-angiotensin-aldosterone system in the L-NAME-induced hypertension model, and the protective effect of ivabradine. L-NAME increased systolic blood pressure and left ventricular weight, enhanced hydroxyproline concentration in the LV, and deteriorated LV function. Ivabradine reduced heart rate and systolic blood pressure, and improved LV function.	Int J Mol Sci. 2018 Oct 3;19(10):3017
