Claim 2:
3. The compound according to claim 1, wherein the compound is a compound shown in a formula (II),, , or a tautomer, mesomer, racemate, enantiomer, and diastereoisomer thereof, or a mixture form thereof, or a pharmaceutically acceptable salt thereof, or a prodrug molecule thereof, wherein
K is, , or E is an oxygen atom;
R3 and R4 are each independently selected from a group consisting of hydrogen, alkyl, cycloalkyl, cycloalkylalkyl, alkylcycloalkyl, aryl, arylalkyl, alkylaryl, heteroaryl, heteroarylalkyl, alkylheteroaryl, heterocyclyl, heterocyclylalkyl, alkylheterocyclyl, alkenylalkyl, and alkynylalkyl, wherein the alkyl, the cycloalkyl, the cycloalkylalkyl, the alkylcycloalkyl, the aryl, the arylalkyl, the alkylaryl, the heteroaryl, the heteroarylalkyl, the alkylheteroaryl, the heterocyclyl, the heterocyclylalkyl, the alkylheterocyclyl, the alkenylalkyl, or the alkynylalkyl is not substituted or is substituted by one or more substituents, each of which is selected from a group consisting of alkyl, cycloalkyl, cycloalkylalkyl, alkylcycloalkyl, aryl, arylalkyl, alkylaryl, heteroaryl, heteroarylalkyl, alkylheteroaryl, heterocyclyl, heterocyclylalkyl, alkylheterocyclyl, alkenyl, alkynyl, amino, hydroxyl, mercapto, carboxyl, alkoxyl, cycloalkoxyl, haloalkyl, alkoxycarbonyl, acyloxy, amido, ureido, alkylsulfonyl, arylsulfonyl, haloalkyl, halogen, cyano, nitro, nitroso, thiocyano, isothiocyano, thioalkyl, sulfo, phosphate, phosphonate, alkylphosphate, alkylphosphonate, arylphosphate, and arylphosphonate;
or R3 and R4 together with a nitrogen atom for linking R3 and R4 form heterocyclyl, which is a monocyclic ring, a bicyclic ring or a tricyclic ring, or a fused ring, a bridge ring or a spiro-ring, wherein the heterocyclyl comprises at least one N atom or one, two or three heteroatoms optionally selected from N, S and O, and is not substituted or is optionally substituted by one or more substituents, each of which is independently selected from a group consisting of alkyl, cycloalkyl, cycloalkylalkyl, alkylcycloalkyl, aryl, arylalkyl, alkylaryl, heteroaryl, heteroarylalkyl, alkylheteroaryl, heterocyclyl, heterocyclylalkyl, alkylheterocyclyl, alkenyl, alkynyl, amino, hydroxyl, mercapto, carboxyl, alkoxyl, cycloalkoxyl, haloalkyl, alkoxycarbonyl, acyloxy, amido, ureido, alkylsulfonyl, arylsulfonyl, haloalkyl, halogen, cyano, nitro, nitroso, thiocyano, isothiocyano, thioalkyl, sulfo, phosphate, phosphonate, alkylphosphate, alkylphosphonate, arylphosphate, and arylphosphonate, which are used as a substituent alone or in a free combination thereof.
