MedKoo CAT#: 561398

CAS#: 1820684-31-8

Description: M443 is a specific small molecule inhibitor of MRK. M443 strongly radiosensitizes UW228 medulloblastoma cells as well as UI226 patient-derived primary cells, whereas it does not affect the response to radiation of normal brain cells. M443 also inhibits radiation-induced activation of both p38 and Chk2, two proteins that act downstream of MRK and are involved in DNA damage-induced cell-cycle arrest.
