What is CMS-121 Powder?
CMS‑121 Powder (CAS 1353224‑53‑9, ≥99% HPLC) is a potent, orally active ACC1 inhibitor with multi‑modal activity: neuroprotective, antioxidant, anti‑inflammatory, and renoprotective. It protects neurons at nM concentrations, improves cognition in aging models, and reduces renal inflammation. Ideal for neuroscience, metabolic, and anti‑aging R&D, its high purity and stability ensure reliable in vitro/in vivo results.
High purity ≥98%–99% (HPLC/LC‑MS) with strict impurity control
Orally bioavailable, stable crystalline form
Potent nM‑range activity in cellular assays
Multi‑target: neuroprotective, antioxidant, anti‑inflammatory, renoprotective
Well‑characterized in vitro & in vivo models


CMS-121 PowderMechanism of Action
1. Enzyme Target Inhibition
Inhibits acetyl‑CoA carboxylase 1 (ACC1) and fatty acid synthase (FASN)
Reduces lipid synthesis and peroxidation
Potently suppresses oxidative stress‑induced cell death and ferroptosis
2. Antioxidant and Anti‑inflammatory Effects
Scavenges reactive oxygen species (ROS) and reduces lipid peroxides
Inhibits the NF‑κB pathway and pro‑inflammatory cytokines (TNF‑α, IL‑6, etc.)
Alleviates oxidative stress and inflammation
3. Neuroprotective Pathways
Upregulates Akt phosphorylation, protecting neurons against ischemia‑reperfusion injury
Maintains brain mitochondrial gene expression and acetyl‑CoA levels
Improves cognition and slows neuronal degeneration
4. Other Protective Effects
Protects renal endothelial cells and reduces kidney injury
Attenuates age‑related hearing loss by inhibiting oxidative stress and ferroptosis

CMS-121 Powder Key Application Areas (Research Progress)
1. Neurodegenerative Diseases
In Alzheimer's disease mouse models: reduces lipid peroxidation, improves cognition and memory, and slows neuronal degeneration
Shows potential neuroprotection in Parkinson's disease models
2. Ischemic Brain Injury
In oxygen‑glucose deprivation/reoxygenation (OGD/R) neurons and mouse ischemia‑reperfusion models:
Reduces neurological deficit scores
Decreases infarct volume
Attenuates neuronal damage
3. Age‑Related Hearing Loss
In SAMP8 mice: inhibits ferroptosis and oxidative stress, delaying hearing decline
4. Kidney Protection
Reduces renal ischemia‑reperfusion injury
Decreases markers of inflammation and oxidative damage
5. Metabolic and Aging‑Related Diseases
Improves lipid metabolism disorders
Delays age‑related decline in cellular function
CMS-121 Powder Comparison with Related Compounds
| Compound | Core Targets | Advantages | Primary Applications |
|---|---|---|---|
| CMS‑121 | ACC1/FASN | Potent ferroptosis inhibition; strong neuroprotection | Neurodegenerative diseases, ischemic brain injury |
| Fisetin | Multiple antioxidant pathways | Natural source; high safety | Anti‑aging, metabolic regulation |
| 1‑MNA | Anti‑inflammatory pathways | Vitamin B3 metabolite; strong anti‑inflammatory effects | Cardiovascular, skin, neuroprotection |
| Urolithin A | Mitophagy | Activates PINK1/Parkin; strong anti‑aging effects | Anti‑aging, sports nutrition |
CMS‑121 is more potent than natural fisetin in ferroptosis inhibition and neuroprotection.
