Binding of the transcriptional co-activator, YAP1, to the transcription factor Oct4, induces Sox2, which is a transcription actor necessary for the self-renewal of stem-like cells from non-small cell lung cancer. The WW domain of YAP1 binds to the PPxY motif of Oct4 to induce Sox2. Delivering a peptide corresponding to the WW domain could prevent the induction of Sox2 and sternness. Similarly, peptides and mimetics of the PPxY motif would be able to inhibit sternness. Disclosed are compounds that affect the Yap1:Oct4 interaction.

The WW domain of YAP1 binds to the PPxY motif of Oct4 to induce Sox2. Delivering a peptide corresponding to the WAV domain could prevent the induction of Sox2 and stemness. Similarly, peptides and mimetics of the PPxY motif would be able to inhibit stemness. Disclosed are compounds that affect the Yap1:Oct4 interaction.

The present invention provides methods and uses of inhibitors of histone deacetylase 11 (HDAC11) in the treatment of diseases and/or disorders, such as, for example, cell proliferative diseases.

Methods using HDAC11 inhibitors

The disclosed modulators of Rb:Raf-1 interactions are potent, selective disruptors of Rb:Raf-1 binding, with ICvalues 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.
