CPC C12Q 1/04 (2013.01) [C07D 311/18 (2013.01); C09K 11/07 (2013.01); G01N 33/56911 (2013.01)] | 6 Claims |
1. A compound or a fluorescent probe selected from the group consisting of:
(A) a compound or a fluorescent probe obtained by connecting an amino group of a coumarin fluorescent dye having the amino group at position 7 of a coumarin skeleton and a carboxyl group of myristoyl asparagine via an amide bond;
(B) a compound or a fluorescent probe obtained by connecting an amino group of a naphthalimide fluorescent dye having the amino group at position 4 of a naphthalimide skeleton and a carboxyl group of myristoyl asparagine via an amide bond;
(C) a compound or a fluorescent probe obtained by connecting an amino group of naphthalene, pyrene or anthracene having the amino group at position 2 thereof and a carboxyl group of myristoyl asparagine via an amide bond;
(D) a compound or a fluorescent probe obtained by connecting one or both of amino groups of a rhodamine fluorescent dye having the amino group at position 3 and/or 9 of a xanthene skeleton and carboxyl group(s) of myristoyl asparagine via an amide bond;
(E) a compound or a fluorescent probe obtained by connecting one or both of amino groups of Bodipy fluorescent dye having the amino group at position 1 and/or 7 of Bodipy mother nucleus and the carboxyl group(s) of myristoyl asparagine via an amide bond;
(F) a compound or a fluorescent probe obtained by connecting said carboxyl group and said amino group in any one of (A) to (E) via alanine (—NH—CH(CH3)-CO—) (each forms an amide bond with alanine);
(G) a compound or a fluorescent probe obtained by connecting a carboxyl group of myristoyl asparagine and a hydroxyl group of oFlu, which is a fluorescent group that exhibits fluorescence when the hydroxyl group is released, via a self-cleavable linker, wherein the selfcleavable linker is connected to the carboxyl group of myristoyl asparagine via an amide bond;
and the hydroxyl group of oFlu is liberated when the amide bond is decomposed by hydrolysis; and
(H) a compound or fluorescent probe having a fluorescent dye connected to a carboxyl group of myristoyl asparagine via an amide bond, wherein fluorescence is emitted after the amide bond is cleaved in a ClbP dependent manner.
