2
, or a substituted C.
The invention relates to novel compound of the general formula (I), in which R has the meanings indicated in Claim
1
, to the preparation thereof and to the use thereof as medicaments. The compounds (I) are inhibitors of steroid sulfatase and are used for the treatment of cancer.
Provided is steroid sulfatase inhibitors comprising, as the active ingredient, an estra-1,3,5(10)-triene derivative which is represented by formula (I):
1
{wherein R
1
and R
2
are the same or different and represent a hydrogen atom, a lower alkyl group or, etc.; R
3
represents a hydrogen atom etc.; R
4
represents a hydrogen atom etc.; R
5
represents a hydrogen atom etc.; R
6
represents a cyano group, an amino group, COR
53
(wherein R
53
represents a substituted lower alkyl group etc.), a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, etc}, or pharmaceutically acceptable salts thereof.
