Claims (37)

1. A compound having a structure of formula (I), a pharmaceutically acceptable salt thereof or an optical isomer thereof,

wherein,

ring A is a 5- to 6-membered heteroaryl;

X is N, C(R) or C;

R is H, a halogen, OH, CN, NO 2 , or selected from the group consisting of an amino, a C 1-6 alkylamino, a N,N-di(C 1-6 alkyl)amino, a C 1-6 alkyl, a C 1-6 heteroalkyl, a C 2-6 alkenyl, a C 2-6 alkynyl, a C 3-7 cycloalkyl, a C 3-7 heterocycloalkyl, a 5- to 7-membered aryl, and a 5- to 7-membered heteroaryl, each of which is optionally substituted by any substituent;

each of V and W is independently selected from the group consisting of a methylene, —CH 2 CH 2 —, C(═O), —S(═O)— and —S(═O) 2 —, wherein, the methylene and the —CH 2 CH 2 — are optionally substituted by 1 or 2 R(s);

Z is a methylene which is optionally substituted by 1 or 2 R(s);

L is a single bond, —O—, —S—, N(R), C(R)(R), —C(═O)—, —C(═S)—, —S(═O)—, or —S(═O) 2 − ;

each of R 1 and R 2 is independently selected from H, a halogen, OH, CN, NO 2 , or each of R 1 and R 2 is independently selected from the group consisting of an amino, a C 1-6 alkyl, a C 1-6 heteroalkyl, a C 2-6 alkenyl, a C 2-6 alkynyl, a C 3-7 cycloalkyl, a C 3-7 cycloalkyl-C 1-6 alkyl, a C 3-7 heterocycloalkyl, a 5- to 7-membered aryl or heteroaryl, each of which is optionally substituted by any substituent independently selected from the group consisting of H, F, Cl, Br, I, OH, ON, NH 2 , a C 1-4 alkyl and a C 1-4 heteroalkyl, wherein the C 1-4 alkyl and the C 1-4 heteroalkyl are optionally further substituted by 0 to 3 substituents selected from a halogen, OH, and NH 2 ;

optionally, the substituent R on Z and the substituent R on V are attached to the same atom or atomic group to form a 5- to 7-membered ring;

optionally, the moiety

may be replaced with

R 2 may also be absent;

m is 1, 2 or 3;

n is 0, 1, 2 or 3;

the “hetero” represents a heteroatom or a hetero-atomic group, which is selected from the group consisting of —C(═O)NH—, —NH—, —C(═NH)—, —S(═O) 2 NH—, —S(═O)NH—, —O—, —S—, N, ═O, ═S, —C(═O)O—, —C(═O)—, —C(═S)—, —S(═O)—, —S(═O) 2 —, and —NHC(═O)NH—;
