A method for the treatment of anemia, hypoxia, ischemia, peripheral vascular disease, myocardial infarction, stroke, diabetes, obesity, inflammatory bowel disease, ulcerative colitis, Crohn's disease, wounds, infection, burns and bone fracture comprising the step of administering to a patient in need thereof a therapeutically effective amount of compound having PHD inhibitor activity of formula (I):
- wherein:
- n is 2-4;
- each R1 is independently selected from H, halo, —C1-4alkyl, —C3-8cycloalkyl, —C1-4perhaloalkyl, trifluoroC1-4alkoxy, —OH, —NO2, —CN, CO2H, —OC1-4alkyl, —SC1-4alkyl, —S(C1-4alkyl)-Rc, —S(O)2(C1-4alkyl)-Rc, —S(O)—C1-4alkyl, —SO2—C1-4alkyl, —S—Rc, —S(O)—Rc, —SO2—Rc, —SO2—NH—Rc, —O—Rc, —CH2—O—Rc, —C(O)NH—Rc, —NRaRb, benzyloxy optionally substituted with Rd, phenyl or monocyclic heteroaryl optionally substituted with Rd, —C3-8cycloalkyl optionally containing O, S or N wherein said —C3-8cycloalkyl is optionally substituted with Rd, and two adjacent R1 groups may be joined to form an optionally substituted 3-8 member ring optionally containing one or more O, S or N;
- Ra and Rb are each independently H, C1-4alkyl, —C(O)C1-4alkyl, —C(O)—Rc, —C(O)CH2—Re, C1-4alkyl-Re, —SO2—Rc, —SO2—C1-4alkyl, phenyl optionally substituted with Rd, benzyl optionally substituted with Rd or monocyclic heteroaryl ring optionally substituted with Rd;
- or Ra and Rb can be taken together with the nitrogen to which they are attached to form an optionally substituted monocyclic heterocycloalkyl ring optionally containing one or more heteroatoms;
- Rc is —C3-8cycloalkyl, phenyl optionally substituted with Rd, benzyl optionally substituted with Rd, or a monocyclic heteroaryl ring optionally substituted with Rd;
- Rd is independently —H, halo, —OH, —C1-4alkyl or —C1-4perhaloalkyl, trifluoroC1-4alkoxy, —OC1-4alkyl, —O-phenyl, or —O-benzyl;
- Re is —C3-8heterocycloalkyl optionally containing one or more O, S or N;
- R2 and R3 are both H, —CF3, or C1-3alkyl;
- each Z is C or N, provided that no more than two Z's can simultaneously be N;
- and
- enantiomers, diastereomers, racemates, and pharmaceutically acceptable salts thereof.
