Patent Claims:	1. A compound of Formula (B) having the structure: wherein: Y is alkylene or substituted alkylene, or a 4-, 5-, or 6-membered cycloalkyl ring; each Ra is independently H, halogen, —CF3, —CN, —NO2, OH, NH2, -La-(substituted or unsubstituted alkyl), -La-(substituted or unsubstituted alkenyl), -La-(substituted or unsubstituted heteroaryl), or -La-(substituted or unsubstituted aryl), wherein La is a bond, O, S, —S(═O), —S(═O)2, NH, C(O), CH2, —NHC(O)O, —NHC(O), or —C(O)NH; G is a Michael acceptor; R12 is H or lower alkyl; or Y and R12 taken together form a 4-, 5-, or 6-membered heterocyclic ring; or pharmaceutically acceptable salt thereof. 2. The compound of claim 1, having the structure: 3. The compound of claim 2, wherein Ra is -La-(substituted or unsubstituted aryl). 4. The compound of claim 3, Ra is —O-(substituted or unsubstituted phenyl). 5. The compound of claim 4, wherein Y and R12 taken together form a 4-, 5-, or 6-membered heterocyclic ring. 6. The compound of claim 5, wherein Y and R12 taken together form a pyrrolidine ring. 7. The compound of claim 5, wherein Y and R12 taken together form a piperidine ring. 8. The compound of claim 4, wherein Y is a 4-, 5-, or 6-membered cycloalkyl ring. 9. The compound of claim 8, wherein Y is a 6-membered cycloalkyl ring. 10. The compound of claim 4, wherein Y is substituted alkylene. 11. A pharmaceutical composition comprising a therapeutically effective amount of a compound of claim 1, and a pharmaceutically acceptable excipient. 12.
