Fluorescent sensor compounds having the formula:
1
wherein L is selected from the group consisting of alkyl, alkylene, aryl, cycloalkyl, alkoxy, aryloxy, arylalkyl, and arylalkyloxyl;
each m, m′, n, n′, p, and p′ is independently an integer from 0 to 4, inclusive; and
each R
1
, R′

and R′
3
is independently selected from the group consisting of hydrogen, alkyl, alkylene, aryl, cycloalkyl, alkoxy, aryloxy, arylalkyl, arylalkyloxyl, halo, substituted and unsubstituted amino, and substituted and unsubstituted thiol, are useful for the selective detection of saccharides such as glucose and sialyl Lewis X. The compounds find particular use in detecting saccharides in biological samples, and in detecting cancer cells that express cell surface polysaccharides such as sialyl Lewis X.
具有以下公式的荧光传感器化合物:1其中L选择自烷基,烷基烯,芳基,环烷基,烷氧基,芳氧基,芳基烷基和芳基烷氧基的群;每个m,m',n,n',p和p'是独立的整数,范围从0到4,包括0和4;每个R1,R'1,R2,R'2,R3和R'3是独立选择自氢,烷基,烷基烯,芳基,环烷基,烷氧基,芳氧基,芳基烷基,芳基烷氧基,卤素,取代和未取代氨基,以及取代和未取代硫醇的群,可用于选择性检测葡萄糖和唾液酸Lewis X等糖类。该化合物在检测生物样品中的糖类和检测表达细胞表面多糖体如唾液酸Lewis X的癌细胞中具有特殊用途。
