FIELD: chemistry.SUBSTANCE: invention relates to a novel heterocyclic compound of formula (I). In formula (I), each of R1 and R2 independently represents H, a halogen atom, an amino, C1-6 alkyl, C4-5 heterocycloalkyl containing in ring 1–2 nitrogen atoms or nitrogen atom and oxygen atom； or R1 and R2 together with two carbon atoms to which they are bonded, are C4 heterocycloalkyl containing a nitrogen atom as a heteroatom, phenyl or 5-member heteroaryl containing a nitrogen atom in the cycle, a sulphur atom or two nitrogen atoms, where each of the C4-5 heterocycloalkyl, phenyl and heteroaryl is optionally substituted with a halogen atom, C1-6 alkyl, C1-6 alkoxy or C(O)ORa, in which Ra is H or C1-10 alkyl； and each of R3 and R4 independently represents NRbRc, or , wherein at least one of R3 and R4 is , in which each of Rb and Rc independently represents H or C1-6 alkyl； R5 is H, C1-6 alkyl, benzyl, optionally substituted cyano, or 5-member heteroaryl C1 alkyl containing 2 nitrogen atoms as heteroatoms； R6 is H； L1 is 5-member heteroaryl containing 3 nitrogen atoms as heteroatoms, C4-5 heterocycloalkyl containing 1–2 nitrogen atoms in a cycle, NH or NRd, in which Rd is C(O)(CH2)2CHNH2CO2Re, where Re is H or C1-6 alkyl； R7 is H, C1-6 alkyl, C1-6 alkoxy, C3-10 cycloalkyl, C4 heterocycloalkyl containing in the cycle a nitrogen atom or a nitrogen atom and an oxygen atom, phenyl or 5- or 6-member heteroaryl containing 1–3 nitrogen atoms as heteroatoms, wherein each of said C1-6 alkyl, C1-6 alkoxy, C3-10 cycloalkyl, C4 heterocycloalkyl, phenyl and heteroaryl is optionally substituted with hydroxy, hydroxy C1-6 alkyl, halogen atom, amino C1-6 alkyl, amino C3-10 cycloalkyl, amino C4 heterocycloalkyl, C3-10 cycloalkyl, C4 heterocycloalkyl containing a nitrogen atom and an oxygen atom in the cycle, phenyl, optionally substituted with halogen, or 5-member heteroaryl containing 2 nitrogen atoms as heteroatoms； m is 1–6； n is equal to 2–3； each of R8 and R9 independently represen
