The present application provides bifunctional compounds of Formula (X): ##STR00001##
or an enantiomer, diastereomer, or stereoisomer thereof, or pharmaceutically acceptable salt, hydrate, solvate, or prodrug thereof, which act as protein degradation inducing moieties for protein kinases. The present application also relates to methods for the targeted degradation of one or more protein kinases through the use of the bifunctional compounds that link a ubiquitin ligase-binding moiety to a ligand that is capable of binding to one or more protein kinases which can be utilized in the treatment of disorders modulated by protein kinases.

The present disclosure relates to bifunctional compounds, which find utility as modulators of α-synuclein (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, 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.

The present disclosure provides, inter alia, bivalent nanobody molecules and methods for treating or ameliorating the effects of a disease, such as long QT syndrome, or cystic fibrosis, in a subject, using the bivalent nanobody molecules disclosed herein. Also provided are methods of identifying and preparing nanobody binders that target proteins of interest.

The present disclosure relates to bifunctional compounds, 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.

Disclosed are bispecific compounds (degraders) that target α-synuclein protein for degradation. Also disclosed are pharmaceutical compositions containing the degraders and methods of using the compounds to treat neurodegenerative diseases.

A bioorthogonal molecule can include a molecule having a structure according the above wherein R.sup.1-R.sup.8 are independently selected from H, a substituted or unsubstituted C.sub.1-C.sub.4 alkyl or alkylene group, COOH, COOR.sup.9, COR.sup.9, CONR.sup.9R.sup.10, CN, CF.sub.3, and SO.sub.2R.sup.9, and where R.sup.9 and R.sup.10 are independently selected from H and a substituted or unsubstituted C.sub.1-C.sub.4 alkyl or alkylene group, with the proviso that one of R.sup.3-R.sup.8 comprises a leaving group, and wherein X is O, S, N, SO, SO.sub.2, SR.sup.+, Se, PO.sub.2.sup.−, or NRR′.sup.+, and where R and R′ are independently selected from H or a substituted or unsubstituted C.sub.1-C.sub.4 alkyl or alkylene group. ##STR00001##
