Stemregenin 1 is a potent aryl hydrocarbon receptor (AhR) antagonist with IC50 of 127 nM.
Stemregenin 1 (SR1) acts by antagonizing the aryl hydrocarbon receptor (AhR). Stemregenin 1 increases the number of CD34+ cells after 5 to 7 days with an EC50 of ~120 nM. Stemregenin 1 inhibits photoaffinity ligand (PAL) binding (IC50=40 nM) These results support the conclusion that Stemregenin 1 -induced CD34+ cell expansion is mediated through direct binding and inhibition of the AhR[1]. An aryl hydrocarbon receptor antagonist, Stemregenin 1 (SR1), robustly promotes ex vivo expansion of human CD34+ cells. Stemregenin 1 treatment accelerates the proliferation of CD34+ cells and decreases the expression levels of VentX[2].
