SS-LUP-332 FAQ: Comparison of REV-ERB Agonists for Metabolic Research
Researchers evaluating REV-ERB agonists for metabolic studies often compare SS-LUP-332 with SR9009 (stenabolic) and GSK4112, two other commonly used compounds in this class. Each has distinct pharmacological properties that influence protocol design. SS-LUP-33

- Researchers evaluating REV-ERB agonists for metabolic studies often compare SS-LUP-332 with SR9009 (stenabolic) and GSK4112, two other commonly used compounds in this class. Each has distinct pharmacological properties that influence protocol design.
- SS-LUP-332
- High selectivity for REV-ERBα/β
- Moderate (requires parenteral dosing)
- Increased thermogenesis, mitochondrial biogenesis
- 14 days at 2–8°C
- Studies requiring selective REV-ERB modulation with minimal off-target effects
- SR9009
- Moderate selectivity, some off-target kinase activity
- Very low (essentially zero oral bioavailability)
- Enhanced exercise endurance, lipid oxidation
- 7 days at 2–8°C
- Short-term metabolic flux studies; avoid for long-term protocols
- GSK4112
- Lower selectivity, affects other nuclear receptors
- Low to moderate
- Circadian rhythm disruption, altered feeding behavior
- 21 days at 2–8°C
- Circadian biology research; less suitable for pure metabolic studies
- GW501516 (comparison. PPAR agonist, not REV-ERB)
- N/A. Different mechanism (PPARδ agonist)
- Moderate oral bioavailability
- Increased fat oxidation, endurance
- 30 days at 2–8°C
- Mechanistic comparison: PPAR-mediated vs REV-ERB-mediated metabolic effects
- SS-LUP-332 offers the best balance of selectivity and in vivo activity for researchers specifically interested in REV-ERB-mediated metabolic pathways. SR9009 suffers from bioavailability issues that make dose-response studies unreliable, and GSK4112's off-target effects complicate interpretation when metabolic endpoints are the primary outcome. For protocols where you need clean, reproducible REV-ERB modulation without confounding variables, SS-LUP-332 is the superior choice.
