Claim:
A method for treating anemia comprising administering to a human or mammal in need of treatment an effective amount of one or more compounds having the formula: wherein R is a unit chosen from: i) substituted or unsubstituted phenyl; or ii) substituted or unsubstituted heteroaryl; said substitutions chosen from: i) C 1 -C 4 linear, branched, or cyclic alkyl; ii) C 1 -C 4 linear, branched, or cyclic alkoxy; iii) C 1 -C 4 linear, branched, or cyclic haloalkyl; iv) halogen; v) —CN; vi) —NHC(O)R 4 vii) —C(O)NR 5a R 5b ; viii) heteroaryl; or ix) two substitutions can be taken together to form a fused ring having from 5 to 7 atoms; R 4 is C 1 -C 4 linear, branched, or cyclic alkyl; R 5a and R 5b are each independently: i) hydrogen; ii) C 1 -C 4 linear, branched, or cyclic alkyl; or iii) R 5a and R 5b can be taken together to form a ring having from 3 to 7 atoms; R 2 is chosen from: i) —OR 6 ; or ii) —NR 7a R 7b ; R 6 is hydrogen or C 1 -C 4 linear, branched, or cyclic alkyl; R 7a and R 7b are each independently: i) hydrogen; ii) C 1 -C 4 linear, branched, or cyclic alkyl; or iii) R 7a and R 7b can be taken together to form a ring having from 3 to 7 ring atoms; R 3 is hydrogen, methyl, or ethyl; L is a linking unit having the formula: —[C(R 8a R 8b )] n — R 8a and R 8b are each independently hydrogen, methyl, or ethyl; the index n is from 1 to 3; R 9 is hydrogen or methyl; or a pharmaceutically acceptable salt thereof.
