The present disclosure relates to
bifunctional compounds, ULM- L-PTM, which find utility as modulators of Rapidly Accelerated
Fibrosarcoma (RAF, such as c-RAF, A- RAF and / or B-RAF; the
target protein). 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 RAF, 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, or the constitutive activation of the target protein, are treated or prevented with compounds and compositions of the present disclosure.
