BIFUNCTIONAL SUBSTITUED PYRIMIDINES AS MODULATORS OF FAK PROTEOLYSE
-
Paragraph 00400; 00418, (2020/02/16)
The present disclosure relates to bifunctional compounds, which find utility as modulators of focal adhesion kinase (FAK) or protein tyrosine kinase 2 (PTK2). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

Enzymatic inhibition has proven to be a successful modality for the development of many small-molecule drugs. In recent years, small-molecule-induced protein degradation has emerged as an orthogonal therapeutic strategy that has the potential to expand the druggable target space. Focal adhesion kinase (Fak) is a key player in tumor invasion and metastasis, acting simultaneously as a kinase and a scaffold for several signaling proteins. While previous efforts to modulate Fak activity were limited to kinase inhibitors with low success in clinical studies, protein degradation offers a possibility to simultaneously block Fak's kinase signaling and scaffolding capabilities. Here, we report the development of a selective and potent Fak degrader, PROTAC-3, which outperforms a clinical candidate, defactinib, with respect to Fak activation as well as Fak-mediated cell migration and invasion. These results underline the potential that PROTACs offer in expanding the druggable space and controlling protein functions that are not easily addressed by traditional small-molecule therapeutics.
