[0005]
In summary, thalidomide and its derivatives play a vital role in the treatment of multiple myeloma and other related malignant tumors, but there are few reports of such compounds substituted by heteroatoms. The biological activity needs to be further improved, so it is urgent to design and synthesize a series of highly active thalidomide drugs in order to achieve better curative effect

Abstract
The present disclosure relates to compound shown in a formula (I) or salts, solvates, isotope-enriched analogs, tautomers, polymorphs, stereoisomers, or mixtures of stereoisomers of the compound, andthe application thereof in the treatment of tumours. The present disclosure also provides tumor treatment application of the compound showed in a formula (I') or pharmaceutically acceptable salts, solvates, isotope-enriched analogs, tautomers, polymorphic substances, stereoisomers, or mixtures of stereoisomers of the compound.
Description
technical field [0001] The present disclosure generally relates to compounds represented by general formula (I) or salts, solvates, isotopically enriched analogs, tautomers, polymorphs, stereoisomers (including enantiomers) ), or mixtures of stereoisomers, and their use in the treatment of tumors. [0002] Background technique [0003] Multiple myeloma (Multiple myeloma, MM) is a malignant blood cancer, accounting for about 1% of all tumors and 10% of hematological malignancies. The clinical manifestations are anemia, renal dysfunction, repeated infection, and osteolytic bone destruction, and it mostly occurs in middle-aged and elderly people. The main treatment for multiple myeloma is chemotherapy and early autologous stem celltransplantation, but this treatment has poor prognosis and high recurrence rate. The latest research results show that immunomodulatory drugs are an important cornerstone in the treatment of multiple myeloma, which has an important impact on the...
