Abstract

The present invention provides bivalent inhibitors of BET bromodomains, such as compounds of Formulae (I), (II), (III), (IV), (V), and (VI). Some bromodomain-containing proteins (e.g., BRD4) have a tandem bromodomain primary structure comprising more than one bromodomain binding site (e.g., BRD4 comprises BD1 and BD2). Bivalent inhibitors of BET bromodomains provided herein can target bromodomains through advantageous multivalent interactions, and can therefore can be to treat diseases or conditions associated with bromodomain-containing proteins. The present also provides pharmaceutical compositions and kits comprising the inventive compounds, as well as methods of using the inventive compounds.

First claim

or a pharmaceutically acceptable salt, stereoisomer, or tautomer thereof, wherein:
L is a linker comprising 1-40 carbon atoms, selected from the group consisting of optionally substituted alkylene, optionally substituted heteroalkylene, optionally substituted alkenylene, optionally substituted heteroalkenylene, optionally substituted alkynylene, optionally substituted heteroalkynylene, optionally substituted carbocyclylene, optionally substituted heterocyclylene, optionally substituted arylene, optionally substituted heteroarylene, and any combination thereof;
each instance of R 1 , R 2 , R 3 , and R 4 is independently hydrogen, halogen, —CN, —NO 2 , —N 3 , optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted acyl, —OR a , —N(R b ) 2 , or —SR c ;
each instance of R a is independently hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted acyl, or an oxygen protecting group;
each instance of R b is independently hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted acyl, or a nitrogen protecting group; or optionally two R b are joined together with the intervening carbon atoms to form optionally substituted heterocyclyl or optionally substituted heteroaryl;
each instance of R c is independently hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted acyl, or a sulfur protecting group;
R 5 is hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted aralkyl, optionally substituted heteroarylalkyl, optionally substituted heterocyclylalkyl, optionally substituted carbocyclylalkyl, optionally substituted acyl, —OR 5a , or —N(R 5b ) 2 ;
each instance of R 5a is independently hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted aralkyl, optionally substituted heteroarylalkyl, optionally substituted heterocyclylalkyl, optionally substituted carbocyclylalkyl, optionally substituted acyl, or an oxygen protecting group;
each instance of R 5b is independently hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted aralkyl, optionally substituted heteroarylalkyl, optionally substituted heterocyclylalkyl, optionally substituted carbocyclylalkyl, optionally substituted acyl, or a nitrogen protecting group; or optionally two R 5b are joined together with the intervening carbon atoms to form optionally substituted heterocyclyl or optionally substituted heteroaryl; and
each instance of m is independently 0, 1, 2, 3, 4, or 5.
