Inhibition of cell membrane
Webb1 maj 2016 · Phosphonic acids (like fosfomycin) inhibit the cell wall enzyme MurA and are used in some Gram-negative bacterial infections. Though, like many of the other antibiotics that target the membrane, several different forms of resistance to fosfomycin have developed, such as decreased drug uptake, and antibiotic inactivation [10]. WebbTo harvest the membranes, source cells (10 9 cells) were washed using phosphate-buffered saline (PBS) twice and lysed in 10 mL of hypotonic lysis buffer containing 10 mM Tris–HCl (pH 7.5), 1 mM KCl, 1 mM MgCl 2, and one phosphatase inhibitor cocktail tablet (Roche, Mannheim, Germany) per 10 mL of solution.

WebbInhibition of Cell Wall Biosynthesis by Antibiotics Antibiotics are molecules that specifically target and kill cells. The term antibiotic is frequently used interchangeably with the word antibacterial, but antiviral, antifungal and antineoplastic compounds are also classified as antibiotics. WebbInhibitors of Membrane Function A small group of antibacterials target the bacterial membrane as their mode of action (Table 4). The polymyxins are natural polypeptide antibiotics that were first discovered in 1947 as products of Bacillus polymyxa; only polymyxin B and polymyxin E ( colistin) have been used clinically.
