In some preferred embodiments, the compound ##STR1## is formulated together with pharmaceutically acceptable diluent or carrier for topical use in the treatment of androgen-dependent diseases associated with the skin.Type: GrantFiled: June 7, 1995Date of Patent: January 18, 2000Assignee: EndorechercheInventors: Fernand Labrie, Yves Merand, Shankar M. Singh
-
Patent number: 5879711Abstract: Pharmaceutical compositions for the topical treatment of androgen-related conditions, e.g., acne in humans containing an amount of the compound represented by formula II effective for the topical treatment of the androgen-related conditions, e.g., acne ##STR1## dissolved in an alcohol-water solvent system, such as ethanol-water ?97.6:2.4(w/w)! and having an apparent pH in the range of about 3.5 to 4.5, and containing a gelling agent are disclosed.Type: GrantFiled: November 7, 1997Date of Patent: March 9, 1999Inventors: Joel A. Sequeira, Fernand Labrie, Shanshank Mahashabde, Nicholas DeAngelis, Yves Merand, Marc Fournier
-
Patent number: 5840735Abstract: Inhibitors of sex steroid activity, for example those having the general structure ##STR1## may be used as part of a pharmaceutical composition to provide antiestrogenic effects and/or to suppress estrogen synthesis. Such pharmaceutical compositions are useful for the treatment of breast cancer or other diseases whose progress is aided by activation of sex steroid receptors.Type: GrantFiled: August 3, 1994Date of Patent: November 24, 1998Assignee: Endorecherche Inc.Inventors: Fernand Labrie, Yves Merand
-
Patent number: 5686437Abstract: Novel derivatives of estrogenic nuclei, contain a side-chain substitution of the formula --R.sup.1 ?B--R.sup.2 --!.sub.x L--G and may be used in pharmaceutical compositions as sex steroid activity inhibitors useful in the treatment of both androgen-related and estrogen-related diseases.Type: GrantFiled: June 7, 1995Date of Patent: November 11, 1997Assignee: Endorecherche Inc.Inventors: Fernand Labrie, Yves Merand

Such pharmaceutical compositions are useful for the treatment of breast cancer or other diseases whose progress is aided by activation of sex steroid receptors.Type: GrantFiled: June 7, 1995Date of Patent: November 11, 1997Assignee: Endorecherche Inc.Inventors: Fernand Labrie, Yves Merand
-
Patent number: 5585405Abstract: Certain steroidal and non-steroidal compounds have been found to inhibit androgen and estrogen formation. Such inhibition may aid in the reduction of the activity of these hormones and may be useful in the treatment of diseases where, for example, inhibition of androgen or estrogen activity is desired. Preferred inhibitors also possess antiestrogenic activity, thus providing the advantage of a double inhibitory action both on estrogen formation and on estrogen action (blockade of estrogen receptors by antiestrogenic action).Type: GrantFiled: August 1, 1994Date of Patent: December 17, 1996Assignee: Endorecherche Inc.Inventors: Fernand Labrie, Yves Merand
