Aurantiamide

Avis client

Based on 1 Customer Validation

Aurantiamide is a non-covalent, orally active, blood-brain-permeable GRPR selective antagonist with anti-inflammatory and neuroprotective effects. Aurantiamide reduces inflammation and oxidative stress in renal tissue by inhibiting GRPR-mediated renal necrosis pathways (such as RIPK3/MLKL signaling) and NF-κB inflammatory pathways, exerting anti-acute kidney injury and endothelial function activities. Aurantiamide also inhibits the M1 polarization of microglia and inhibits NLRP3 activation, thereby improving AD mouse models. Aurantiamide has in vivo inhibitory efficacy in acute kidney injury models such as ischemia/reperfusion, sepsis, and hypertension models.

In Vitro

Aurantiamide (25, 50, 100 μM; 12 h) significantly reduces the protein and mRNA expression of the renal injury marker KIM1 in the human renal proximal tubular epithelial cell (HK-2) hypoxia/reoxygenation and LPS (1 mg/mL) stimulation model, inhibits the phosphorylation of proteins related to the RIPK3/MLKL necrosis pathway and NF-κB inflammatory pathway, and alleviates cell damage and inflammatory response^[1].
Aurantiamide (10, 20 μM; 24 h) inhibits LPS and IFN-γ-induced BV2 activation and M1 polarization in mouse BV2 cells, inhibited the activation of NLRP3, and thus exerted anti-CNS inflammatory activity^[2].
Aurantiamide promotes M2 polarization of microglia and improves cognitive ability of Alzheimer's disease mice^[3].
Aurantiamide (3 μM; 18 h) significantly upregulates the mRNA and protein expression of endothelial nitric oxide synthase (eNOS) in human umbilical vein endothelial cells (HUVECs), promotes the production of nitric oxide (NO), and has no significant toxic effect on cell viability^[4].

WB (Western blot) : Reduced protein expression of renal injury marker KIM1, phosphorylated RIPK3 (p-RIPK3), phosphorylated MLKL (p-MLKL), and phosphorylated P65 (p-P65) in a dose-dependent manner, compared to H/R or LPS-stimulated controls.
qPCR : Downregulated mRNA levels of KIM1, MCP-1, and IL-6, with significant inhibition at 50 μM and 100 μM.
IF (Immunofluorescence) : Decreased immunofluorescent intensity of p-MLKL and KIM1 in cytoplasm, indicating reduced necroptosis and tubular injury.

Human umbilical vein endothelial cells (HUVEC)
Concentration:

3 μM
Incubation Time:

18 h
Result:

No significant cytotoxicity observed, with cell viability maintaining over 90% compared to control.
WB (Western blot) : Upregulated eNOS protein expression by 1.8-fold compared to control, with enhanced NO production detected by nitrite/nitrate assay.
\qPCR : Increased eNOS mRNA expression by 2.3-fold, confirming transcriptional activation of eNOS.

In Vivo

Aurantiamide (2.5, 5, 10 mg/kg; oral gavage; 3 times, 24 hours apart) improves cognitive impairment in C57BL/6 mice after ischemia/reperfusion (I/R) and cecal ligation and puncture (CLP) in a dose-dependent manner, and inhibits microglial polarization and NLRP3 activation^[2].
Aurantiamide (0.5 mg/kg; intraperitoneal injection; once a day, 5 days a week; 4 weeks) significantly reduces mean arterial blood pressure, improves endothelium-dependent vasodilation, upregulates aortic endothelial nitric oxide synthase (eNOS) protein expression and promotes nitric oxide (NO) production in the two-kidney-one-clip (2K-1C) renovascular hypertension model in Sprague-Dawley rats^[4].
The metabolic characteristics of Aurantiamide (0.1 mg/kg; oral gavage; single dose) and Aurantiamide acetate (HY-N2905) (0.2 mg/kg; oral gavage; single dose) in rats shows that they have the characteristics of rapid diffusion, wide distribution, and can pass through the blood-brain barrier, with a peak time of 0.5 h. In addition, the decline rate of aurantiamide acetate is faster than that of aurantiamide^[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Male C57BL/6 mice (6-8 weeks old, 20-22 g) + cisplatin-induced, I/R, or CLP-induced acute kidney injury model^[1]

Result:

Renal function : Reduced serum creatinine and BUN levels by 30-45% compared to model controls, with the 10 mg/kg dose showing the most pronounced effect.
Histopathology : PAS staining revealed decreased tubular dilation, glycogen deposition, and interstitial fibrosis; immunofluorescence showed reduced KIM1 (renal injury marker) and F4/80⁺ macrophage infiltration in renal tissues.
Protein expression : Western blot demonstrated dose-dependent inhibition of p-RIPK3, p-MLKL, and p-P65 (NF-κB) in renal lysates, with corresponding reduction in pro-inflammatory cytokines (IL-6, TNF-α) by qPCR.

Animal Model:

Male Sprague-Dawley rats (8 weeks old, 230-250 g) + two-kidney one-clip (2K-1C) renovascular hypertension model^[4]

Administration:

Intraperitoneal injection, once daily for 5 days/week, total 4 weeks
Result:

Blood pressure : Reduced mean arterial pressure (MAP) by 20-25% compared to hypertensive controls, with significant improvement in endothelium-dependent relaxation to acetylcholine (ACh) and reduced constriction to phenylephrine (Phe).
Vascular function : Organ bath assays showed enhanced ACh-induced vasodilation and attenuated Phe-induced vasoconstriction in aortic rings, correlated with increased eNOS protein expression (1.5-fold by Western blot) and NO production (measured as nitrite/nitrate levels).
Red blood cell deformability : Ektacytometry revealed increased erythrocyte deformability (Elmax) in treated rats, indicating improved blood fluidity and microvascular flow.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
