Anti-chrondrosarcoma compounds
View Patent ↗The invention provides inhibitors of chondrosarcoma cell growth that are useful as anti-cancer and anti-tumor agents. The inhibitors are peptides having sequences related to cleavage regions of the proenzyme forms of matrix metalloproteinases and that can inhibit the activity of matrix metalloproteinases. The peptide inhibitors of the invention can be formulated into therapeutic compositions, lotions, creams and wound dressings.
1. A method for decreasing growth of chondrosarcoma cells that comprises contacting a chondrosarcoma cell with an effective amount of a peptide selected from the group consisting of SEQ ID NO:11, SEQ ID NO:12, or SEQ ID NO:13.
2. The method of claim 1 , wherein the peptide is SEQ ID NO: 11.
3. A method for decreasing growth of chondrosarcoma cells in a mammal that comprises administering an effective amount of a peptide selected from the group consisting of SEQ ID NO: 11, SEQ ID NO:12 or SEQ ID NO:13 to the mammal.
4. The method of claim 1 or 3 , wherein decreasing growth of chondrosarcoma cells decreases growth of conventional chondrosarcoma, myxoid chondrosarcoma, mesenehymal chondrosarcoma, clear cell chondrosarcoma, or dedifferentiated (spindle cell) chondrosarcoma.
5. The method of claim 3 , wherein the chondrosarcoma cells comprise a tumor.
6. The method of claim 5 , wherein the tumor is metastatic, non-metastatic, vascularized, non-vascularized, hard or soft.
7. The method of claim 5 , wherein the peptide is administered locally to the tumor.
