Modulators of 5′-nucleotidase, ecto and the use thereof
Compounds that modulate the conversion of AMP to adenosine by 5′-nucleotidase, ecto, and compositions containing the compounds and methods for synthesizing the compounds, are described herein. The use of such compounds and compositions for the treatment and/or prevention of a diverse array of diseases, disorders and conditions, including cancer- and immune-related disorders, that are mediated by 5′-nucleotidase, ecto is also provided.
1. A compound having the structure
or a pharmaceutically acceptable salt thereof.
2. A compound selected from the group consisting of
or a pharmaceutically acceptable salt thereof.
3. A method of treating a disease, disorder, or condition, mediated at least in part by CD73, said method comprising administering to a subject an effective amount of a compound of claim 2 , or a pharmaceutically acceptable salt thereof.
4. The method of claim 3 , wherein said disease, disorder, or condition is cancer.
5. The method of claim 4 , wherein said cancer is a cancer of the prostate, colon, rectum, pancreas, cervix, stomach, endometrium, brain, liver, bladder, ovary, testis, head, neck, skin, mesothelial lining, white blood cell, esophagus, breast, muscle, connective tissue, lung, adrenal gland, thyroid, kidney, or bone; or is glioblastoma, mesothelioma, renal cell carcinoma, gastric carcinoma, sarcoma, choriocarcinoma, cutaneous basocellular carcinoma, or testicular seminoma.
6. The method of claim 5 , wherein the cancer is selected from the group consisting of melanoma, colon cancer, pancreatic cancer, breast cancer, prostate cancer, small-cell lung carcinoma, non-small-cell carcinoma, leukemia, a brain tumor, lymphoma, ovarian cancer, and Kaposi's sarcoma.
7. The method of claim 3 , wherein said disease, disorder, or condition is an immune-related disease, disorder, or condition selected from the group consisting of rheumatoid arthritis, kidney failure, lupus, asthma, psoriasis, colitis, pancreatitis, allergies, fibrosis, anemia fibromyalgia, Alzheimer's disease, congestive heart failure, stroke, aortic valve stenosis, arteriosclerosis, osteoporosis, Parkinson's disease, infections, Crohn's disease, ulcerative colitis, allergic contact dermatitis and other eczemas, systemic sclerosis, and multiple sclerosis.
8. A method of treating cancer in a subject, said method comprising administering to said subject an effective amount of a compound of claim 2 , or a pharmaceutically acceptable salt thereof and an immune checkpoint inhibitor.
9. The method of claim 8 , wherein the immune checkpoint inhibitor inhibits PD-1, PD-L1, A 2a R, BTLA, CTLA-4, TIM-3, or LAG-3.
