  • Publication number: 20230295118
    Abstract: Disclosed herein are compounds of Formula (I): or a pharmaceutically acceptable salt, hydrate, solvate, prodrug, stereoisomer, or tautomer thereof, which act as protein degradation inducing moieties for cyclin-dependent kinase 4 (CDK4) and/or cyclin-dependent kinase 6 (CDK6). These compounds are useful in methods for the targeted degradation of CDK4 and/or CDK6 through the use of the bifunctional compounds that link a ubiquitin ligase-binding moiety to a ligand that is capable of binding to CDK4 and/or CDK6 which can be utilized in the treatment of disorders modulated by CDK4 and/or CDK6.

  • Publication number: 20230137175
    Abstract: The present disclosure relates to bifunctional compounds that serve as degraders (and/or inhibitors) of Bruton's tyrosine kinase (BTK). In the present disclosure, the bifunctional compounds, which contain a target protein (BTK) binding moiety and a E3 ubiquitin ligase (CRBN) binding moiety, are directed to bind to both the BTK and CRBN, such that the BTK is placed in close proximity to the E3 ligase to mediate ubiquitylation of the target protein followed by degradation of the target protein by the proteasome. The present disclosure provides methods for synthesizing the herein disclosed bifunctional compounds, and their pharmacological activities associated with degradation or inhibition of the target protein.

  • Publication number: 20220348595
    Abstract: The present disclosure relates to bifunctional compounds that serve as degraders (and/or inhibitors) of the estrogen receptor (target protein). In the present disclosure, the bifunctional compounds, which contain a target protein (estrogen receptor) binding moiety and a E3 ubiquitin ligase (CRBN) binding moiety, are directed to bind to both estrogen receptor and CRBN, such that the ER is placed in close proximity to the E3 ligase to mediate ubiquitylation of the target protein followed by degradation of the target protein by the proteasome. The present disclosure provides methods for synthesizing the herein disclosed bifunctional compounds, and their pharmacological activities associated with degradation or inhibition of the target protein. Further, the present disclosure teaches the utilization of such compounds in a treatment for proliferative diseases, including cancer, particularly breast cancer, and especially ER+ breast cancer.
