Twonovel chlorinated fluoresceins 2′,4′,5′,7′-tetrachloro-6-(5-carboxypentyl)-4,7-dichloro fluorescein succinimidyl ester (1G) and 2′,4′,5′,7′-tetrachloro-6-(3-carboxypropyl)-4,7-dichlorofluorescein succinimidyl ester (2G) were synthesized as fluorescent probes for labeling proteins. Structures of target compounds and intermediates were determined via IR, MS, 1H NMR and element analysis. The investigation
两种新型氯化荧光素2',4',5',7'-四氯-6-(5-羧基戊基)-4,7-二氯荧光素琥珀酰亚胺酯(1G)和2',4',5',7'-合成了四氯-6-(3-羧丙基)-4,7-二氯荧光素琥珀酰亚胺酯(2G)作为标记蛋白质的荧光探针。通过IR,MS,1 H NMR和元素分析确定目标化合物和中间体的结构。免疫荧光组织化学研究表明,它们具有较强的荧光性,较高的光稳定性和良好的生物相容性。
