Patent number: 6645974Abstract: Compounds of structural formula (I) as herein defined are disclosed as useful in a method for modulating the androgen receptor in a tissue selective manner in a patient in need of such modulation, as well as in a method of agonizing the androgen receptor in a patient, and in particular the method wherein the androgen receptor is antagonized in the prostate of a male patient or in the uterus of a female patient and agonized in bone and/or muscle tissue. These compounds are useful in the treatment of conditions caused by androgen deficiency or which can be ameliorated by androgen administration, including: osteoporosis, periodontal disease, bone fracture, bone damage following bone reconstructive surgery, sarcopenia, frailty, aging skin, male hypogonadism, post-menopausal symptoms in women, atherosclerosis, hypercholesterolemia, hyperlipidemia, aplastic anemia and other hematopoietic disorders, pancreatic cancer, renal cancer, arthritis and joint repair, alone or in combination with other active agents.Type: GrantFiled: July 25, 2002Date of Patent: November 11, 2003Assignee: Merck & Co., Inc.Inventors: John H. Hutchinson, Michael J. Breslin, Gideon A. Rodan, Soumya P. Sahoo, Mark E. Duggan, Shun-Ichi Harada, Azriel Schmidt, Wasyl Halczenko, Dwight A. Towler
