The reaction of bis-sulfone conjugation reagents with disulfide bonds allows the site-specific modification of various peptides and proteins. Herein, we present the intracellular disintegration of bis-sulfide containing somatostatin bioconjugates under controlled, tumor-relevant glutathione levels. GSH responsive release is demonstrated, which offers high potential for designing tumor responsive therapeutics.
双
硫砜偶联试剂与二
硫键的反应能够对各种肽和蛋白质进行位点特异性修饰。在此,我们展示了含有双
硫键的
生长抑素生物共轭物在受控且与肿瘤相关的
谷胱甘肽水平下的细胞内解体。
谷胱甘肽响应性释放被证实,这为设计肿瘤响应性治疗药物提供了巨大潜力。
