| 摘要 |
Fused cyclic pyrimidine compounds, including tautomers thereof, and pharmaceutically acceptable salts, prodrugs, solvates and hydrates thereof, are disclosed. These compounds are useful in methods for treating cancer, selectively targeting cancerous cells via the proton coupled folate transporter, folate receptor alpha, and/or folate receptor beta pathways, inhibiting GARFTase in cancerous cells, and selectively targeting activated macrophages in a patient having an autoimmune disease, such as rheumatoid arthritis. |
