In order to develop orally active pure antiestrogens, we incorporated the carboxy-containing side chains into the 7 alpha-position of the steroid scaffold and found that 17-keto derivative CH4893237 (12b) functioned as a pure antiestrogen with its oral activity much superior to clinically used pure antiestrogen, ICI182,780. Results from the pharmacokinetic evaluation indicated that the potent antiestrogen activity at oral dosing in mice attributed to both improved absorption from the intestinal wall and metabolic stability in liver.

A compound having the following general formula (1):
in which
R1 represents an ethyl group, etc.;
R2 represents a hydrogen atom, etc.;
R3 represents a C1-C5 perhalogenoalkyl group, etc.;
each of R4 and R5 independently represents a hydrogen atom, etc.;
X represents an oxygen atom or a sulfur atom;
m represents an integer of 2 to 14; and
n represents an integer of 2 to 7;
or an enantiomer of the compound, or a hydrate or a pharmaceutically acceptable salt of the compound or its enantiomer is advantageous in pharmaceutical use because of its anti-estrogenic activity.

halogenoalkyl group, etc.,
m represents an integer of 2 to 14, and
n represents an integer of 2 to 7,
or enantiomers of the compound, or hydrates or pharmaceutically acceptable salts of the compound or enantiomers thereof. The above compound is advantageous in pharmaceutical use because the group of general formula (1) allows compounds such as anti-estrogenic ones to show a significantly increased activity following oral administration when attached to the parent scaffolds of the compounds.
