Patent ID: 8053428

Claim:
A method for treating a condition selected from the group consisting of Hodgkin's Disease, breast cancer, and non-small cell lung cancer in mammals, said method comprising: administering to the mammal a therapeutically effective amount of a compound of Formula (I) as follows: where: R 1 is: alkenyl; alkynyl; aryl; heterocyclyl; halogen; CN; CH(O); COR 5 ; SO 2 NHNH 2 ; SO 2 NR 5 NH 2 ; SO 2 NR 5 NHR 6 ; SO 2 NR 5 NR 6 R 7 ; SO 2 NHNHR 5 ; SO 2 NHNR 5 R 6 ; CO 2 R 5 ; SR 5 ; SSR 5 ; SOR 5 ; SO 2 R 5 ; SO 2 NHR 5 ; SO 2 NR 5 R 6 ; B(OR 5 ) 2 ; CF 3 ; SH; SO 2 NH 2 ; NH 2 ; NHR 5 ; NHCOR 5 ; NHSO 2 R 5 ; NR 5 R 6 ; NR 5 COR 6 ; or NR 5 SO 2 R 6 ; R 5 and R 6 can form a ring; R 2 =alkyl or CH(O); R 3 =hydrogen, alkyl, or C(O)R 5 ; R 4 =hydrogen or C(O)R 5 ; R 5 and R 6 each are independently alkyl, alkenyl, alkynyl, aryl, or heterocyclyl; X=OR 5 , NR 5 R 6 , NHNH 2 , NHNHC(O)R 5 , OH, NHR 5 , NH 2 , or NHNHC(O)H; R 4 and X may be linked together with intervening atoms to form a ring; or a pharmaceutically acceptable salt thereof, wherein the alkyl and alkenyl groups may be branched, straight, unsubstituted, and/or substituted and wherein the aryl, alkynyl, and heterocyclyl groups are substituted or unsubstituted.
