  • Publication number: 20250064837
    Abstract: The present disclosure relates to compounds of formula (I) and their anti-tumor uses, and their intermediates of formula (III), and uses of the intermediates. The compound of formula (I) has a degrading effect on a specific target protein, which is mainly composed of three parts. The first part is a small molecule compound (SMBP, Small Molecules Binding Protein) that can bind to a protein, the second part LIN is a linker, and the three-part ULM is a ubiquitin ligand (ULM, Ubiquitin Ligase Binding Moiety), wherein SMBP is covalently bound to LIN, and LIN is covalently bound to ULM. A series of compounds designed and synthesized in the present disclosure have a wide range of pharmacological activities, including the functions of degrading specific proteins and/or inhibiting activities of specific proteins, and thus can be used in related tumor treatments.

  • Patent number: 11639343
    Abstract: The present disclosure provides a compound of formula (I) targeting and degrading BCR-ABL protein and its use in the field of antitumor. The compound of formula (I) shows degradation and inhibitory effects on BCR-ABL target protein, which is mainly comprised of four moieties, wherein the first moiety (BCR-ABL-TKIs) is compound moiety with BCR-ABL tyrosine kinase inhibited activity; the second moiety (the LIN) is link units; the third moiety (the ULM) is a small molecule ligand for VHL or CRBN proteases with ubiquitination; and the four moiety (the group A) is carbonyl group that covalently binds to BCR-ABL-TKIs and LIN, and the LIN is further covalently bonded to ULM. A series of compounds designed and synthesized by the present disclosure shows extensive pharmacological effective, which function to degrade BCR-ABL protein and inhibit BCR-ABL effective, and can be utilized for treating relevant tumor.
