1933 N. K. Adam et al. in Nature 5 Aug. 205/2 The parent saturated hydrocarbon of the œstrin group, C₁₈H₃₀, containing the sterol skeleton with one methyl group but without the side chain, may be termed ‘œstrane’.

1947 H. Selye Textbk. Endocrinol. i. 71/2 A side-chain at C₁₇ does not necessarily decrease folliculoid activity in the estrane series and..it may even increase it.

1973 Biochemistry 12 2221/1 All neutral and charged derivatives of estrane and androstane inhibit hydrolysis of bovine albumin.

2001 European Jrnl. Medicinal Chem. 36 659 The inhibitory activity of compound 7 was as potent as that of its previously reported estrane analogue, 17α-benzyl estradiol.
