1. What are Fatty Acid Synthesis Inhibitors?

Definition:
Fatty acid synthesis inhibitors target enzymes central to lipogenesis, primarily Fatty Acid Synthase (FASN), a multifunctional enzyme catalyzing de novo fatty acid production. Overexpression of FASN is linked to tumor growth, metabolic disorders, and pathogenic infections, making it a therapeutic target.

Target Enzymes and Pathways:

Enzyme	Role	Therapeutic Potential	Examples
FASN (Fatty Acid Synthase)	Catalyzes synthesis of palmitate	Cancer, obesity, infection	TVB-2640, GDC-0660
ACC (Acetyl-CoA Carboxylase)	Converts acetyl-CoA to malonyl-CoA	Metabolic disorders	NDGA, PF-05175157
ACLY (ATP Citrate Lyase)	Links citrate to acetyl-CoA production	Cancer, metabolic syndromes	SB-611075

Clinical Relevance:

• Oncology: Suppresses tumor proliferation by inhibiting lipogenesis required for membrane synthesis.
• Metabolic Diseases: Reduces lipogenesis, impacting obesity and diabetes.
• Infections: Limiting fatty acid synthesis impairs pathogen replication.
