Isosulfazecin (iSZ) 是一种新型 β-内酰胺类抗生素，由嗜酸假单胞菌属新种产生，在有氧条件下，在补充有甘油和硫代硫酸钠的营养液中与细菌生长同时合成。它通过色谱法和甲醇水溶液结晶纯化。物理化学分析确定其分子式为 C12H20N4O9S，显示出具有 β-内酰胺环、甲氧基和磺酸盐基团的结构。酸水解产生 L-丙氨酸和 D-谷氨酸。iSZ 是磺胺嘧啶的差向异构体，对革兰氏阳性菌和革兰氏阴性菌均表现出中等活性，但对耐 β-内酰胺类抗生素的细菌表现出强效活性。

生物活性

Isosulfazecin (iSZ) is a novel β-lactam antibiotic produced by Pseudomonas acidophilus sp., synthesized in a nutrient solution supplemented with glycerol and sodium thiosulfate under aerobic conditions in parallel with bacterial growth. It is purified by chromatography and crystallization from aqueous methanol. Physicochemical analysis determined its molecular formula to be C12H20N4O9S, showing a structure with a β-lactam ring, methoxyl and sulfonate groups. Acid hydrolysis yields L-alanine and D-glutamic acid. iSZ is a diastereomer of sulfadiazine and exhibits moderate activity against both gram-positive and gram-negative bacteria, but potent activity against bacteria resistant to β-lactam antibiotics[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
