SPR-741 CAS 1179330-52-9

Product Overview

SPR-741 (CAS 1179330-52-9), also known as NAB741, is a synthetic polymyxin-derived cyclic peptide designed to permeabilize the outer membrane of Gram-negative bacteria. It acts as an antibiotic potentiator by disrupting lipopolysaccharide interactions in outer cell membranes, facilitating the entry of co-administered hydrophobic molecules during scientific research and pharmacological assays. As a professitional manufacturer of SPR-741 in China, Conscientia Industrial produces this peptide via advanced solid-phase peptide synthesis (SPPS) combined with chromatographic purification to ensure high structural integrity and batch consistency.
