MedKoo CAT#: 463262

CAS#: 216014-14-1 (CRX-527)

Description: CRX-527 is a TLR4 ligand. CRX-527 induced differentiation of HSCs protecting the intestinal epithelium from radiation damage. Administration of CRX-527 improved the survival rate of total body irradiation (TBI) to 100% in wild-type mice but not in TLR4-/- mice. After TBI, hematopoietic system damage was significantly alleviated, and the recovery period was accelerated in CRX-527-treated mice. Moreover, CRX-527 induced differentiation of HSCs and the stimulation of CRX-527 significantly increased the proportion and number of LSK cells and promoted their differentiation into macrophages, activating immune defense.
