Gramicidin S (Gramicidin soviet) is a cationic cyclic peptide antibiotic that selectively targets bacterial cell membranes and has anticancer activity. Gramicidin S also exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S inserts into the phospholipid bilayer through hydrophobic amino acid residues, specifically binds to negatively charged membrane lipids and disrupts membrane structure, thereby inhibiting cell division and cell wall synthesis, and ultimately causing bacterial death. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na +/K +-ATPase, tobacco leaf plasma membrane Mg 2+/K +-ATPase, and rat heart plasma membrane Ca 2+-ATPase, respectively .

Tetrachloroauric acid is an Au (III) compound and bilayer disruptor that can be used to damage red blood cells. Tetrachloroauric acid specifically disrupts the bilayer structure of representative phospholipids (dimyristoylphosphatidylcholine and dimyristoylphosphatidylethanolamine) in human red blood cell membranes, and induces morphological changes in intact human red blood cells. Tetrachloroauric acid causes downregulation of MT I-II and GFAP expression in the mouse brain following chronic treatment. Tetrachloroauric acid is being used in studies related to neurotoxicity and hematotoxicity, including analyses of human red blood cells and molecular models of red blood cell membranes, as well as immunohistochemical evaluation of the mouse brain .

Dehydroergosterol is a fluorescent cholesterol analog (Ex/Em = 325/375 nm) used in cholesterol transport, membrane structure research, and live-cell imaging. Unlike cholesterol, Dehydroergosterol contains three additional double bonds, an extra methyl group, and an ergosterol side chain, forming a conjugated system that produces intrinsic fluorescence. In its monomeric form, Dehydroergosterol exhibits excitation peaks at 310-311, 324, and 338-340 nm, as well as emission peaks at 354, 371-375, 390-394, and 414 nm; in its microcrystalline form, Dehydroergosterol shows enhanced excimer emission around 404 and 426 nm. Dehydroergosterol mimics the properties of cholesterol, integrates into membranes and lipoproteins, and localizes to organelles .
