Patent ID: 7087749

Claim:
A compound of formula II: wherein: R 1 is —OR 7 , —NR 7 R 8 , —COOR 7 , —CONR 7 R 8 , or —CH 2 OH; each R 7 is independently H, alkyl, cycloalkyl, alkylcycloalkyl, or aralkyl; each R 8 is independently H, alkyl, aralkyl, or aryl; R 3 is alkyl; R 6 is H or —(CHR 9 ) m W; each R 9 is independently H, alkyl, cycloalkyl, alkylcycloalkyl, aryl, aralkyl or heteroaryl; W is H, alkyl, cycloalkyl, alkylcycloalkyl, heterocycloalkyl, alkylheterocycloalkyl, aryl, heteroaryl, —CH 2 OH, —CH 2 OR 7 , or —C(═O)R 10 ; R 10 is —OR 7 or —NR 7 R 11 ; R 11 is H, alkyl, aralkyl, aryl or —(CHR 9 ) n C(═O )R 12 ; R 12 is —OR 7 or —NR 7 R 8 ; m is an integer from 1 to 4; and n is an integer from 1 to 4; provided that when R 1 is —OH, then W is heterocycloalkyl, alkylheterocycloalkyl, —CH 2 OH, or —C(═O)R 10 ; and when R 1 is —OH and W is heterocycloalkyl or alkylheterocycloalkyl in which the heterocyclic ring moiety of the heterocycloalkyl or alkylheterocycloalkyl contains only one heteroatom, wherein the heteroatom is nitrogen, then the heterocyclic ring moiety is connected to —(CHR 9 ) m — through a heterocyclic ring carbon atom; or a stereoisomer, prodrug, pharmaceutically acceptable salt, hydrate, solvate, acid hydrate or N-oxide form thereof.
