Abstract

Described herein are compounds of Formula (I), pharmaceutically acceptable salts thereof, and pharmaceutical compositions thereof. Compounds of the present invention are useful for inhibiting PRMT5 activity. Methods of using the compounds for treating PRMT5-mediated disorders are also described.

Claims (62)

1 . A compound of Formula (I):

or a pharmaceutically acceptable salt thereof,

wherein

represents a single or double bond;

R 1 is hydrogen, R z , or —C(O)R z , wherein R z is optionally substituted C 1-6 alkyl;

L is —N(R)C(O)—, —C(O)N(R)—, —N(R)C(O)N(R)—, —N(R)C(O)O—, or —OC(O)N(R)—;

each R is independently hydrogen or optionally substituted C 1-6 aliphatic;

Ar is a monocyclic or bicyclic aromatic ring having 0-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur, wherein Ar is substituted with 0, 1, 2, 3, 4, or 5 R y groups, as valency permits;

each R y is independently selected from the group consisting of halo, —CN, —NO 2 , optionally substituted aliphatic, optionally substituted carbocyclyl, optionally substituted aryl, optionally substituted heterocyclyl, optionally substituted heteroaryl, —OR A , —N(R B ) 2 , —SR A , —C(═O)R A , —C(O)OR A , —C(O)SR A , —C(O)N(R B ) 2 , —C(O)N(R B )N(R B ) 2 , —OC(O)R A , —OC(O)N(R B ) 2 , —NR B C(O)R A , —NR B C(O)N(R B ) 2 , —NR B C(O)N(R B )N(R B ) 2 , —NR B C(O)OR A , —SC(O)R A , —C(═NR B )R A , —C(═NNR B )R A , —C(═NORA)R A , —C(═NR B )N(R B ) 2 , —NR B C(═NR B )R B , —C(═S)R A , —C(═S)N(R B ) 2 , —NR B C(═S)R A , —S(O)R A , —OS(O) 2 R A , —SO 2 R A , —NR B SO 2 R A , or —SO 2 N(R B ) 2 ;

each R A is independently selected from the group consisting of hydrogen, optionally substituted aliphatic, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, and optionally substituted heteroaryl;

each R B is independently selected from the group consisting of hydrogen, optionally substituted aliphatic, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, and optionally substituted heteroaryl, or two R B groups are taken together with their intervening atoms to form an optionally substituted heterocyclic ring;

R 5 , R 6 , R 7 , and R 8 are independently hydrogen, halo, or optionally substituted aliphatic;

each R x is independently selected from the group consisting of halo, —CN, optionally substituted aliphatic, —OR′, and —N(R″) 2 ;

R′ is hydrogen or optionally substituted aliphatic;

each R″ is independently hydrogen or optionally substituted aliphatic, or two R″ are taken together with their intervening atoms to form a heterocyclic ring; and

n is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, as valency permits.

2 - 3 . (canceled)

4 . The compound of claim 1 , wherein the compound is of Formula (I′):
