Description:SPR741是一種衍生自多粘菌素B的陽離子多肽,序列中含有9個氨基酸,并且含有酰胺鍵的環(huán)狀結構,是一種增效劑分子。SPR741可提高革蘭氏陰性細菌外膜的通透性,用于抑制嚴重的革蘭氏陰性細菌感染。SPR741抑制具有多重耐藥性的革蘭氏陰性細菌。當與抗生素結合使用時,SPR741具有擴展抗生素活性譜的能力。
SPR741 is a cationic peptide derived from Polymyxin B, with a sequence containing 9 amino acids and a cyclic structure containing amide bonds. It is a synergistic molecule. SPR741 can improve the permeability of the outer membrane of Gram negative bacteria and be used to inhibit severe Gram negative bacterial infections. SPR741 inhibits Gram negative bacteria with multiple drug resistance. When used in combination with antibiotics, SPR741 has the ability to expand the antibiotic activity spectrum.
