Abstract:
Inhibition of acetyl-CoA carboxylase (ACC), with its resultant inhibition of fatty acid synthesis and stimulation of fatty acid oxidation, has the potential to favorably affect, in a concerted manner, a multitude of the cardiometabolic risk factors associated with diabetes, obesity, and the metabolic syndrome. Studies in ACC2 knockout mice and in experimental animals treated with isozyme-specific antisense oligonucleotides or with isozyme-nonselective ACC inhibitors have demonstrated the potential for treating metabolic syndrome through this modality. Co-crystallization of the biotin carboxylase and carboxyltransferase domains of eukaryotic ACC in the presence of substrates and inhibitors has revealed characteristics of the catalytic center that can be exploited in drug discovery. A variety of structurally diverse, mechanistically distinct classes of ACC inhibitors have been disclosed in the scientific and patent literature. Isozyme-nonselective ACC inhibitors may provide the optimal therapeutic potential. However, demonstration of the full potential of isozyme-selective inhibitors, once identified, should reveal advantages and liabilities associated with single isozyme inhibition.
Insights
Inhibiting acetyl-CoA carboxylase (ACC) can improve heart health and metabolic risk factors by reducing fat synthesis and increasing fat breakdown. This approach shows promise for treating metabolic syndrome, obesity, and diabetes.
Area of Science:
- Biochemistry
- Pharmacology
- Metabolic Diseases
Background:
- Acetyl-CoA carboxylase (ACC) regulates fatty acid synthesis and oxidation.
- Dysregulation of ACC is linked to cardiometabolic risk factors like obesity and diabetes.
- Targeting ACC offers a potential therapeutic strategy for metabolic syndrome.
Purpose of the Study:
- To explore the therapeutic potential of inhibiting acetyl-CoA carboxylase (ACC) for cardiometabolic risk factors.
- To review the current landscape of ACC inhibitors and their therapeutic implications.
- To assess the potential of isozyme-selective vs. nonselective ACC inhibition.
Main Methods:
- Review of scientific and patent literature on ACC inhibitors.
- Analysis of studies involving ACC2 knockout mice and animal models.
- Examination of co-crystallization data of ACC domains with substrates and inhibitors.
Main Results:
- ACC inhibition favorably affects cardiometabolic risk factors by inhibiting fatty acid synthesis and stimulating oxidation.
- Studies in animal models demonstrate the potential of ACC inhibition for metabolic syndrome treatment.
- Diverse classes of ACC inhibitors have been identified, with varying mechanisms.
Conclusions:
- ACC inhibition is a promising therapeutic strategy for metabolic syndrome, obesity, and diabetes.
- Isozyme-nonselective ACC inhibitors may offer optimal therapeutic benefits.
- Further research is needed to fully elucidate the advantages and liabilities of isozyme-selective inhibitors.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...
