(±) erso

(S)-ErSO is an inactive dextrorotatory enantiomer of ErSO.

(Rac)-ErSO-DFP is a derivative of ErSO-DFP and a selective small molecule Erα biomodulator. (Rac)-ErSO-DFP overactivates ERα+-dependent anticipatory unfolded protein responses and exhibits anti-estrogen receptor alpha-positive breast cancer, including its resistant tumours.

ErSO is a selective activator of anticipatory unfolded protein response (UPR) via ERα receptor. ErSO can be used in studies about anti-cancer.

(±)-ErSO is the racemic form of ErSO. ErSO is a selective anticipatory activator of the unfolded protein response (a-UPR).

ErSO-DFP is an expected activator of the unfolded protein response (a-UPR). erSO-DFP improves selectivity for oestrogen receptor alpha+ (ERα+) cancer cells with higher selectivity than ErSO. erSO-DFP has anti-tumour effects and significantly eliminates MCF-7 tumours in a mouse model.
