- C1 to C8 alkyl optionally substituted with one or more substituents independently selected from hydroxyl, halogen, C1 to C4 alkoxy, C1 to C4 alkoxy-C1 to C4 alkoxy, amino, alkylamino, dialkylamino, acetamide, —C(O)—Rb, —C(O)O—-Rb, aryl, morpholinyl, thiomorpholinyl, pyrrolidinyl, piperidinyl, piperazinyl, 1,3-dioxolan-2-one, oxiranyl, tetrahydrofuranyl, tetrahydropyranyl, 1,2,3-triazole, 1,2,4-triazole, furan, imidazole, isoxazole, isothiazole, oxazole, pyrazole, thiazole, thiophene or tetrazole;
- wherein amino is optionally substituted with C1 to C4 alkoxycarbonyl, imidazole, isothiazole, pyrazole, pyridine, pyrazine, pyrimidine, pyrrole or thiazole, wherein pyridine and thiazole are each optionally substituted with C1 to C4 alkyl;
- wherein alkylamino and dialkylamino are each optionally substituted on alkyl with hydroxyl, C1 to C4 alkoxy, imidazole, pyrazole, pyrrole or tetrazole;
- and
- wherein morpholinyl, thiomorpholinyl, pyrrolidinyl, piperidinyl, piperazinyl and oxiranyl are each optionally substituted with —C(O)—Rn, —C(O)O—Rn or C1 to C4 alkyl, wherein C1 to C4 alkyl is optionally substituted with hydroxyl;
- Rb is hydroxyl;
- amino;
- alkylamino, optionally substituted on alkyl with hydroxyl, amino, alkylamino or C1 to C4 alkoxy;
- C1 to C4 alkoxy;
- C2 to C8 alkenyl;
- C2 to C8 alkynyl;

- Rd is phenyl optionally substituted by one or more substituents independently selected from halogen, nitro, C1 to C6 alkyl, —C(O)O—Re, and —ORe;
- Re is hydrogen;
- C1 to C6 alkyl optionally substituted with one or more substituents independently selected from halogen and alkoxy;
- or phenyl, wherein phenyl is optionally substituted with one or more substituents independently selected from halogen and alkoxy;
- and
- Rn is hydroxyl, C1 to C4 alkoxy, amino or C1 to C6 alkyl;
- wherein the compound reduces VEGF levels as measured by an ELISA assay or a quantitative immunofluorescence assay, or reduces VEGF levels in HT1080 clones stably expressing epitope-tagged VEGF with a 5′-UTR;
- and
- wherein the disease is solid tumor cancer, diabetic retinopathy, rheumatoid arthritis, psoriasis, atherosclerosis, chronic inflammation, a chronic inflammation-related disease or disorder, obesity, or exudative macular degeneration.
A method for treating a disease associated with elevated levels of VEGF in a subject in need thereof comprising administering a therapeutically effective amount of a compound selected from the group consisting of:
- or a pharmaceutically acceptable salt, racemate or stereoisomer thereof, to the subject;
- and wherein the disease is solid tumor cancer, diabetic retinopathy, rheumatoid arthritis, psoriasis, atherosclerosis, chronic inflammation, a chronic inflammation-related disease or disorder, obesity, or exudative macular degeneration.
