EXP3179
Based on 1 Customer Validation
EXP3179 (Losartan Carboxaldehyde) is a metabolite of Losartan (HY-17512). EXP3179 binds to AT1R with an affinity of 20 nM and blocks ANGII-induced AT1R signaling, inhibiting ERK1/2 activation. EXP3179 reduces NADPH oxidase activity. EXP3179 inhibits Phenylephrine (HY-B0769)-induced aortic contraction through an endothelium-dependent, NO-dependent mechanism. EXP3179 dose-dependently inhibits type I collagen-induced platelet aggregation and activation through GPVI binding, reducing platelet adhesion to the injured site. EXP3179 lowers blood pressure in normotensive and spontaneously hypertensive rats and mice. EXP3179 can be used for research on type 2 diabetes, hypertensive heart disease, hypertension, thrombosis, and coronary artery disease.

In Vitro
EXP3179, as a metabolite of Losartan (HY-17512), reduces NADPH oxidase activity in circulating leukocytes[2].
EXP3179 (25 μM) blocks ANGII-AT1R signaling in HEK-AT1R cells[3].
EXP3179 (25 μM) completely blocks ANGII-induced ERK1/2 phosphorylation in primary rASMCs at 25 μM[3].
EXP3179 (500 μM) dose-dependently inhibits type I collagen-induced platelet aggregation and activation, with a significant effect at 500 μM[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. Further protocols information, click here.
In Vivo
EXP3179 (10 mg/kg; intravenous injection) significantly reduces systolic and diastolic blood pressure in spontaneously hypertensive rats within 30 min[3].
EXP3179 significantly reduces platelet adhesion at the site of vascular injury in a mouse carotid artery injury model[4].
EXP3179 (subcutaneous injection) does not mediate the antitumor effect of Losartan in orthotopic PDAC tumor-bearing mice; instead, the antitumor activity is mediated by EXP3174[7].

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.94 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Protocols

Research Protocol for Cardiovascular Diseases
Cardiovascular disease can be modeled as maladaptive cardiac remodeling, where ischemic injury or pressure overload activates inflammatory signaling, fibroblast activation, extracellular-matrix deposition, cardiomyocyte hypertrophy, vascular remodeling, and progressive ventricular dysfunction. The TGF-β/SMAD axis is a central profibrotic pathway after myocardial injury and pressure overload, while innate immune and cytokine pathways regulate leukocyte recruitment, scar formation, and adverse remodeling. Key unresolved questions include which inflammatory signals are reparative versus harmful, when fibrosis is protective versus maladaptive, and whether pathway inhibition improves function without weakening necessary infarct healing or compensatory remodeling.

Research Protocol for Metabolic Diseases
AMP-activated protein kinase, AMPK, is a conserved cellular energy sensor that responds to reduced cellular energy status and coordinates metabolism by increasing ATP-generating catabolic pathways while suppressing ATP-consuming anabolic processes. In metabolic disease research, the AMPK pathway is experimentally relevant because it regulates hepatic lipid synthesis, fatty acid oxidation, glucose production, skeletal-muscle glucose disposal, mTORC1-linked biosynthesis, autophagy, mitochondrial homeostasis, and whole-body energy balance. The central pathway logic is that energy stress, metformin, exercise-like stimulation, or direct AMPK activators increase AMPKα Thr172 phosphorylation and downstream substrate phosphorylation, including ACC and RAPTOR. Phosphorylation of ACC suppresses lipogenesis and supports fatty acid oxidation, whereas phosphorylation of RAPTOR suppresses mTORC1 signaling and links cellular energy status to growth and protein synthesis control. The pathway is linked
