Two lysosome-targeting fluorescent anion transporters derived from coumarins, trifluoromethylated arylsquaramides and morpholines were synthesized, and their specificity and efficiency to target and alkalize lysosomes were investigated. They are able to target lysosomes specifically. Compared with the previous analogue without trifluoromethyl substituents, these two conjugates, in particular the one
合成了两种香豆素靶向的溶酶体荧光阴离子转运蛋白,三氟甲基化的芳基方酸酰胺和吗啉,并研究了它们靶向和碱化溶酶体的特异性和效率。他们能够特异性地靶向溶酶体。与先前的不具有三氟甲基取代基的类似物相比,这两种缀合物,特别是具有3,5-双(三氟甲基)取代基的缀合物,具有促进氯离子转运,碱化溶酶体并降低溶酶体组织蛋白酶活性的显着更高的能力。 B酶。本发现表明,提高靶向溶酶体的荧光阴离子转运蛋白的阴离子活性,有利于碱化溶酶体并使溶酶体组织蛋白酶B酶失活的效率。
