Background:

Estrone 3-sulfate is an endogenous steroid and an estrogen ester that is biologically inactive. It is converted by steroid sulfatase into estrone . Estrone 3-sulfate has been investigated as a ligand for targeting organic anion transporting polypeptides for the detection of hormone-dependent breast cancers.[1]
