Embodiment

[2496] Assay and Degradation Data

[2497] Western blot screen for BRM degradation in SW1573 cells

[2498] To assess BRM degradation (D max and DC 50 ), the cells were seeded in 96-well black / transparent bottom plate at 8000 / well, and each well was 180L DMEM growth medium (containing 1% Pen-Strep, 1% HEPES and 10% FBS). Plates were incubated overnight to allow adhesion. The next morning, cells were treated by adding 20L of 10X compound concentration of interest (1% DMSO) to the appropriate wells and returned to the incubator overnight (18-20 hours). The final concentration of DMSO was 0.1%.

[2499] For lysis, adhered cells were washed once with 100 L DPBS. Cells were lysed in 40L 1X RIPA + HALT protease inhibitors on ice for 10 minutes and then frozen until use at -80C. Thawed lysates were cleaned by filtration in 1.2m filter plates, or by spinning at 2300g for 30 min at 4C.

[2500] For blots, for each Western sample, 30 L of lysate was added to 10 L of 4X LDS sample...

Abstract

The present disclosure relates to bifunctional compounds which find utility as modulators of SMARCA2 or BRM (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a ligand that binds to the Von Hippel-Lindau 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.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application Serial No. 62 / 651,186, filed April 1, 2018, entitled "BRM TARGETING PROTAC COMPOUNDS AND ASSOCIATED METHODS OF USE," and ASSOCIATED METHODS OF USE," U.S. Provisional Patent Application Serial No. 62 / 797,754, both of which are hereby incorporated by reference in their entirety. technical field [0003] This specification provides a bifunctional compound comprising a target protein binding part and an E3 ubiquitin ligase binding part, as well as related methods of use. Bifunctional compounds can be used as modulators targeting ubiquitination, especially with regard to the substrate-associated actin-dependent regulation of yeast mating type switch / sucrose nonfermentation complex (SWI / SNF)-associated chromatin subfamily A member 2 agents (SMARCA2) (ie, BRAHMA or BRM) that are degraded and / or otherwise inhibited by bifunctional compounds according to the present dis...
