A FRET ratiometric fluorescent sensor was developed for detecting H2S in aqueous media and serum, as well as inside live cells. For this sensor, carbon dots serve as the energy donor and also the anchoring site for the probe. This sensor is highly selective and sensitive with a detection limit of 10 nM which is the lowest among fluorescent H2S sensors.

overall increase the prognosis rate. A newseries of substituted naphthalimide moieties conjugated via ester and amide linkages with artesunate were designed, synthesized, and characterized. In addition to the conjugates, to further achieve a theranostic molecule, FITC was incorporated via a multistep synthesis process.

淋巴瘤可以用化疗方案有效治疗,但化疗方案会因耐药性增加而产生不良副作用,因此迫切需要替代的小分子抑制剂来克服淋巴瘤治疗中出现的耐药性并总体提高预后率。设计、合成并表征了一系列通过酯键和酰胺键与青蒿琥酯缀合的新的取代萘酰亚胺部分。除了缀合物之外,为了进一步实现治疗诊断分子,还通过多步合成过程掺入了 FITC。通过紫外可见 (UV-vis)、荧光光谱、嵌入染料(EtBr、吖啶橙)-DNA 竞争性测定和小沟结合染料 Hoechst 33342-DNA 竞争性测定对这些选定衍生物进行 DNA 结合研究表明,合成的新分子由于其萘甲酰亚胺部分而插入 DNA 的两条链之间,而其对应物青蒿酯与 DNA 的小沟结合。萘甲酰亚胺-青蒿琥酯缀合物抑制淋巴瘤的生长并诱导细胞凋亡,包括快速掺入和细胞活力降低。该改造药物对 BALB/c 小鼠体内产生的实体 DL 肿瘤具有显着的杀瘤作用,且呈剂量依赖性。与未经治疗的同
