The disclosed modulators of Rb:Raf-1 interactions are potent, selective disruptors of Rb:Raf-1 binding, with IC.sub.50 values ranging from 80 nM to 500 nM. Further, these compounds are surprisingly effective in inhibiting a wide variety of cancer cells, including osteosarcoma, epithelial lung carcinoma, non-small cell lung carcinoma, three different pancreatic cancer cell lines, two different glioblastoma cell lines, metastatic breast cancer, melanoma, and prostate cancer. Moreover, the disclosed compounds effectively disrupt angiogenesis and significantly inhibited tumors in nude mice derived from human epithelial lung carcinoma tumors. Accordingly, the disclosed compounds, pharmaceutical compositions comprising the compounds, methods of inhibiting cell proliferation, methods of treating subjects with cancer, and methods of preparing the disclosed compounds are provided.

Provided herein are novel compounds that inhibit ribonucleotide reductase (RR) by binding to RRM2 and interfering with the activity of the RRM1/RRM2 holoenzyme, as well as methods of synthesizing these novel compounds. The compounds may be used to inhibit RR activity and to treat various conditions associated with RRM2 expression, such as for example certain cancer types, mitochondrial diseases, or degenerative diseases.

Thiazole analog compounds and their pharmaceutically acceptable salts are disclosed, including pharmaceutical compositions comprising the thiazole analog compounds, either alone or in combination with at least one additional therapeutic agent, and/or with a pharmaceutically acceptable carrier. Methods of using the thiazole analog compounds, either alone or in combination with at least one additional therapeutic agent, in the prophylaxis or treatment of cellular proliferative diseases, such as cancer, are also disclosed.
