Abstract

The present invention relates to a selective estrogen receptor modulator of formula I or Ia: (I) (Ia); or a pharmaceutical acid addition salt thereof; useful for treating vasomotor symptoms, in particular hot flashes, night sweats and other symptoms that affect women around menopause.

Description

The selective estrogen receptor modulators that is used for the treatment of vasomotor symptoms
Background of invention
" vasomotor symptoms " is hot flush, night sweat, vagina drying, somnopathy, feels sick and mood swings, and it influences the women before and after the menopause usually.In fact, most of postmenopausal women all can experience vasomotor symptoms, and sizable per-cent continues to suffer from these symptoms and reaches (Psychosom.Med.1965,27,266 more than 5 years among these women; Med.Gynecol.Soc.1969,4,268).The women who has carried out bilateral oophorectomy, radiotherapy or GnRH (gonadotropin releasing hormone) agonist treatment is easy to take place hot flush (Br.J.Obstet.Gynaecol.1977,84,769) especially.According to reports, vasomotor symptoms is also taking place with (N.Engl.J.Med.1981,305,663) behind the GnRH agonist treatment or at male castration postoperative (Urology 1980,16,620) in the male sex.
Although be confirmed as menopausal complaints existing hundreds of years, the cutter reason is still unclear really to constitute the vasomotor symptoms reason.Yet, extensively be accepted with the contact of decrease in estrogen (due to natural menopause or other situation).What is interesting is, the women who has low estrogen level because of ovarian hypoplasia does not generally suffer from vasomotor symptoms, unless they at first are given hormone replacement therapy (HRT) and then with its termination (Clin.Endocrinol. (Oxf) 1985,22,293), this prompting oestrogenic hormon drug withdrawal may be the potential cause of vasomotor instability.HRT is the preferred standard therapy of present vasomotor symptoms, efficient in the women of begin treatment＞80%, and this provides support for the effect of oestrogenic hormon in its nosetiology once more.
Hot flush (flush) is characterised in that the warmth sensation that starts from chest and move to neck and head, and usually with perspiration, palpitaition and epidermis flush.Outbreak continues 30 seconds to 10 minutes.Think that the hot flush incident itself is the maincenter mediation, because due to the of short duration reduction of hypothalamic temperature regulation setting point (about summary, referring to: Can.J.Physiol.Pharmacol.1987,65,1312).The adjusting of temperature regulation process may relate to catecholamines, oestrogenic hormon, testosterone, opiates and serotonin etc. (about summary, referring to Mayo.Clin.Proc.2002,77,1207).In fact, aspect the treatment hot flush, each the compound of regulating in these hormone/neurotransmitters of signal transduction path is estimated.For example, referring to Ann.Intern.Med.2000,132,788; Br.Med.J.1974, i, 409; Maturitas, 1978,1,21; Med.J.Aust.1986,144,369; Fertil.Steril.1985,43,401; Br.J.Obstet.Gynaecol.1981,88,919; J.Clin.Endocrinol.Metab.1984,58,578; Clin.Endocrinol.1985,22,293; Maturitas 2000,36, and 155; J.Clin.Oncol 2002,20, and 1583; JAMA 2003,289, and 2827; Lancet 2000,356, and 2059; N.Engl.J.Med.1994,331,347; Obstet.Gynecol.1984,63,1; Obstet.Gynecol.1999,94,225; Br.J.Obstet.Gynecol.1998,105,904; Neurology 2000,54, and 2161; Obstet.Gynecol.1998,72,688; J.Clin.Oncol.1998,16,495; J.Clin.Oncol.2001,19,2739; And J.Nutr.2001,131 (11, supplementary issue), 3095s.
Although there is quite a large amount of treatments to can be used for hot flush, at present all therapies all exist the effect difference problem, have unacceptable side effect or there is taboo in some patient colony.For example, the women that mammary cancer, uterus carcinoma, ovarian cancer or venous thromboembolism medical history are arranged is not recommended to use HRT.Recent data show that also HRT may not be suitable for suffering from the women of coronary artery disease.Non-hormonotherapy generally very ineffective (for example clonidine) and/or cause undesirable action (for example Venlafaxine, gabapentin).
Occurred many publications in the past ten years, they disclose selective estrogen receptor modulators (SERM), and for example U.S. Patent No. 5,484, and 795,5,484,798,5,510,358,5,998,401 and WO 96/09040.In general, having been found that has many useful estrogen agonist activity that have in bone and cardiovascular systems among these SERM, has the useful estrogen antagonist activity of following simultaneously in mammary gland.Find that also useful especially sub-fraction has the oestrogenic hormon antagonistic action or has non-estrogen effect in this compounds in the uterus.Yet, the practical application of SERM in the treatment vasomotor symptoms also is subjected to the puzzlement of efficacy problems, for example be used for the treatment of/prevent in the III phase clinical study of postmenopausal osteoporosis at raloxifene, compare with placebo, raloxifene is relevant with the slight increase of the incidence of hot flush, and known tamoxifen brings out hot flush (Arch.Intern.Med.1991,151,1842) in the patient more than 50%.
Therefore, the medical requirement that can overcome the insufficient vasomotor symptoms therapy of existing treatment still is not met.Especially, there are demand in the active effect of disclosed SERM before having such as the raloxifene active effect of bone, uterus, mammary gland and cardiovascular systems (promptly to) and the medicine that can alleviate vasomotor symptoms.
