Cellular membranes and biomolecules

Cellular membranes and biomolecules represent a broad structural and functional category rather than a specific, discrete therapeutic target. Cellular membranes, primarily composed of phospholipid bilayers, serve as essential barriers that regulate the internal environment of the cell, facilitate signal transduction, and manage molecular transport (Source: NIH, 2022). Biomolecules encompass the major classes of macromolecules, including proteins, lipids, carbohydrates, and nucleic acids, which are fundamental to all biological processes. In pharmacology, certain classes of drugs exert their effects by interacting with these structures; for example, polyene antifungals like Amphotericin B bind to ergosterol in fungal membranes to induce pore formation and cell death (Source: StatPearls, 2023). Similarly, lipopeptide antibiotics such as Daptomycin target bacterial membranes to cause rapid depolarization (Source: PubMed, 2020). However, because this term refers to the collective structural components of a cell rather than a specific protein or pathway, it is considered too broad for precise drug-target profiling in clinical development.

Drugs interacting with these structures typically act via physical disruption of the lipid bilayer, formation of transmembrane pores, or sequestration of essential membrane components like ergosterol or lipid II (Source: StatPearls, 2023; PubMed, 2020).
