Lasalocid (CAS 25999-31-9)

Lasalocid is a polyether ionophore, originally isolated from the bacterium Streptomyces lasaliensis. Its structure is characterized by a complex ring system capable of forming stable complexes with various cations, particularly sodium ions. This ability to bind and transport ions across lipid membranes underlies its primary action in research focused on cellular and molecular biology, particularly in the study of ion transport mechanisms. In scientific studies, lasalocid is extensively used to explore ion exchange and the regulation of ion gradients across biological membranes. By binding to sodium ions, lasalocid facilitates their transport across the hydrophobic lipid bilayers of cell membranes, thereby disrupting the natural ion balance within cells. This disruption is crucial for understanding the role of ion gradients in cellular processes such as energy production, signal transduction, and volume regulation. Furthermore, lasalocid′s ionophoric activity makes it an important tool in synthetic and systems biology. It has been employed in constructing synthetic bio-membranes and studying the artificial modulation of ion gradients, which is essential for developing models that mimic biological systems. These studies help explain fundamental biophysical principles and contribute to the design of bio-inspired technologies.
