| Peptide and Peptidomimetic Inhibitors of Smoothened Protein as Anti-neoplastic Agents |
Description of Invention:
Cancer is caused by the improper regulation of certain signaling proteins in the cell. One of these pathways is the Hedgehog/Patched (HH/PTCH) pathway. Hedgehog is a secreted protein involved in the growth and development of embryonic cells. Patched is the receptor for hedgehog proteins and regulates a membrane protein called Smoothened (SMO). This pathway is activated in many tumor cells, including those in prostate, pancreas, stomach, and small cell cancer.
The technology is directed towards several synthetic peptides (including all-D analogs) corresponding to specific region of the SMO protein. Experiments in vitro demonstrate that they potentially suppress the growth of cancer cells and inhibit the expression of the HH/PTCH pathway genes. These novel SMO inhibitors are much more effective in inhibiting cell growth than currently available cyclopamine and cyclopamine derivatives. These novel peptides and their metabolically more stable analogs have a high potential for cancer therapy. Due to their high hydrophobic properties, these can be easily formulated for specific intratumor delivery or topical creams for skin disorders.
Applications:
- A potent, highly soluble cancer therapeutic
- Novel compounds that inhibit HH/PTCH pathway genes
- Skin permeable compounds that can be formulated into tropical creams for skin malignancies treatment and prevention and treatment of psoriasis
Development Status:
The technology is currently in the pre-clinical stage of development.
