Plasma lipids and cell membranes

Plasma lipids and cell membranes represent a broad class of non-protein therapeutic targets essential for cellular structure and systemic metabolism. Plasma lipids, including cholesterol and triglycerides, are primarily targeted to manage cardiovascular risk, while cell membranes serve as the site of action for various anti-infective and anesthetic agents [StatPearls: Hyperlipidemia, 2023]. Drugs like Amphotericin B and Daptomycin exert their effects by binding to specific lipid components such as ergosterol or phosphatidylglycerol, leading to membrane pore formation and cell death [PubMed: PMC4562675]. Additionally, the physicochemical properties of cell membranes influence the pharmacokinetics of nearly all drugs through passive diffusion [NCBI: Membrane Lipids]. While often considered non-specific compared to protein receptors, targeting the lipid environment is a validated strategy in treating dyslipidemia and severe fungal or bacterial infections [NIH: Lipid Metabolism Disorders]. The structural integrity of the lipid bilayer is also a key factor in the mechanism of action for certain general anesthetics [PubMed: 11511513].
