Proteasome Inhibitors for Selectively Inducing Apoptosis in Cancer Cells

The subject invention concerns compounds having activity as inhibitors of proteasomes and methods of using the subject compounds. In one embodiment, a compound of the invention has the chemical structure shown in Formula (I), wherein R1 is an organic cyclic ring structure bonded to a sulfonamide structure; R2 is H, halogen, alkyl, -NR6R7, or heteroalkyl; R3 is H, halogen, -OH, -O-alkyl, alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, -NO2, -NH2 or substituted amines; R4 is H, alkyl, heteroalkyl, aryl, or heteroaryl, any of which can be optionally substituted with one or more of -NO2, alkyl, heteroalkyl, aryl, or heteroaryl, or halogen; R5 is H, -OH, halogen, alkyl, aryl, heteroaryl, cycloalkyl, heterocycloalkyl, -O-alkyl, -O- aryl, heteroalkyl, -NO2, -NH2, or substituted amine; and R6 and R7 are independently H, O, alkyl, aryl, heterocycloalkyl, or heteroaryl, or together can form a heterocycloalkyl or a heteroaryl, any of which can be optionally substituted with one or more of -NO2, alkyl, heteroalkyl, aryl, or halogen; or a pharmaceutically acceptable salt or hydrate thereof. In another embodiment, a compound of the invention has the chemical structure shown in Formula (II), wherein Q, W, X, Y, Z are each independently carbon, oxygen, or nitrogen; R1 is H, or X1R8; R2 is heteroalkyl, which can be optionally substituted with one or more of -OH, halogen, -C(O)OR4, alkyl, heteroalkyl, heterocycloalkyl, or heteroaryl; R3 is heterocycloalkyl, aryl, heteroaryl, any of which can be optionally substituted with one or more of a halogen or -OH; and R4 is H or alkyl; R5 is halogen, alkyl or nitro; R6 is nitro, X2R9 or a halogen; R7 is H or alkyl; R8 is H, alkyl, aryl, CH2-alkyl-aryl, -alkyl-C(O)OH, or alkyl-tetrazole (aromatic and aliphatic heterocyclic groups); R9 is H or alkyl; X1 is oxygen, nitrogen, or sulfur; X2 is oxygen, nitrogen, or sulfur; or a pharmaceutically acceptable salt or hydrate thereof.
