COMPOUNDS FOR MALT1 DEGRADATION

Provided herein are bifunctional compounds that inhibit MALTl and/or promote targeted ubiquitination for the degradation of MALTl. In particular, provided are compounds that can bind MALTl, a protein whose activity is responsible for constitutive NF-KB signaling in certain cancers (e.g., activated B-cell diffuse large B-cell lymphoma (ABC-DLBCL)), and can assist in its degradation by recruiting an E3 ubiquitin ligase (e.g., Cereblon, VHL), which can ubiquitinate MALTl, marking it for proteasome degradation. Also provided are pharmaceutical compositions comprising the bifunctional compounds, methods of treating cancer with the bifunctional compounds, methods of promoting the degradation of MALTl, and methods of binding E3 ubiquitin ligase activity in a subject by administering a compound or composition described herein.

Discovery of ((S)-5-(methoxymethyl)-7-(1-methyl-1 H -indol-2-yl)-2- (trifluoromethyl)-4,7-dihydropyrazolo[1,5- a ]pyrimidin-6-yl)((S)-2-(3- methylisoxazol-5-yl)pyrrolidin-1-yl)methanone as a potent and selective I Kur inhibitor

Previously disclosed dihydropyrazolopyrimidines are potent and selective blockers of IKur current. A potential liability with this chemotype is the formation of a reactive metabolite which demonstrated covalent binding to protein in vitro. When substituted at the 2 or 3 position, this template yielded potent IKur inhibitors, with selectivity over hERG which did not form reactive metabolites. Subsequent optimization for potency and PK properties lead to the discovery of ((S)-5-(methoxymethyl)-7-(1-methyl-1H-indol- 2-yl)-2-(trifluoromethyl)-4,7-dihydropyrazolo[1,5-a]pyrimidin-6-yl)((S) -2-(3-methylisoxazol-5-yl)pyrrolidin-1-yl)methanone (13j), with an acceptable PK profile in preclinical species and potent efficacy in the preclinical rabbit atrial effective refractory period (AERP) model.
