MedKoo CAT#: 206119

CAS#: 334969-03-8 (sodium)

Description: Recilisib, also known as ON 01210.Na, is a radioprotectant, which modifys cell cycle distribution patterns in cancer cells subjected to radiation therapy, and it has been identified as a potential candidate for radiation protection studies. It appears that Recilisib radioprotective mechanisms involve prevention of p53-dependent and independent radiation-induced apoptosis.
