TARGETED BIFUNCTIONAL DEGRADERS

The present invention provides, in one aspect, bifunctional compounds that can be used to promote or enhance degradation of certain circulating proteins. In another aspect, the present invention provides bifunctional compounds that can be used to promote or enhance degradation of certain autoantibodies. In certain embodiments, treatment or management of a disease and/or disorder requires degradation, removal, or reduction in concentration of the circulating protein or the autoantibody in the subject. Thus, in certain embodiments, administration of a compound of the invention to the subject removes or reduces the circulation concentration of the circulating protein or the autoantibody, thus treating, ameliorating, or preventing the disease and/or disorder. In certain embodiments, the circulating protein is TNF.

Chromium-Salen Complex/Nitroxyl Radical Cooperative Catalysis: A Combination for Aerobic Intramolecular Dearomative Coupling of Phenols

We describe an aerobic intramolecular dearomative coupling reaction of tethered phenols using a catalytic system consisting of a chromium-salen (Cr-salen) complex combined with a nitroxyl radical. This novel catalytic system enables formation of various spirocyclic dienone products including those unable to be accessed by previously reported methods efficiently under mild reaction conditions.

SUBSTITUTED 1-METHYL-1,2,3,4-TETRAHYDROISOQUINOLINE MOLECULES AS PCSK9 ALLOSTERIC BINDERS

The present invention relates to PCSK9 allosteric binding compounds of Formula I: (Formula (I)) and pharmaceutically acceptable salts thereof, wherein X1, X2, Y, R1, R2, RA, RB and n are as defined herein. The present invention also relates to compositions which comprise an allosteric binding compound of the invention or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier. The invention further relates, inter alia, to methods for inducing PCSK9 protein degradation in a subject, and methods for treating atherosclerosis, hypercholesterolemia, coronary heart disease, metabolic syndrome, acute coronary syndrome, or related cardiovascular disease and cardiometabolic conditions, comprising administering to a subject an effective amount of a compound or a pharmaceutically acceptable salt of the invention. The invention also provides a means for the in vitro labeling, detection and/or quantification of PCSK9 in biological samples.
