MedKoo Cat#: 206045 | Name: Reparixin

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Reparixin is an inhibitor of CXCR2 function, which attenuates inflammatory responses and promotes recovery of function after traumatic lesion to the spinal cord. In a human breast cancer cell line, both reparixin reduced the number of breast cancer stem cells compared with no treatment. I n mice with primary human breast cancer xenografts, reparixin alone or in combination with docetaxel reduced tumor growth compared with saline control. The combination had greater efficacy than either reparixin or docetaxel alone.
