  • Genital Morphology and Reproductive Function in the Rat B
    Long-term effects of prenatal oestrogen treatment on genital morphology and reproductive function in the rat B. Vannier and J. P. Raynaud Centre de Recherches Roussel Uclaf, 93230 Romainville, France Summary. Prenatal exposure to RU 2858(11\g=b\-methoxy-19-nor-17\g=a\-pregna\x=req-\ 1,3,5(10)-trien-20-yne-3,17-diol) alters the genital tract of rat offspring more markedly than does oestradiol which is bound to a specific plasma protein. The morphological changes observed in the male fetus are partly restored during infancy and maturity. The main effect of the treatment is seen in the female offspring and consists of alterations of the genital tract and of reproductive function. Introduction Numerous studies on the action and mechanism of perinatal oestrogen treatment in the rat have been reported, many of which are concerned with effects on sexual behaviour after oestrogen ad¬ ministration to the newborn (Whalen & Nadler, 1963; Gorski, 1963; Levine & Mullins, 1964; Harris & Levine, 1965; Barraclough, 1968; Passouant-Fontaine & Flandre, 1969; Dorner, Docke & Hinz, 1971; Brown-Grant, 1974; Brown-Grant, Fink, Greig & Murray, 1975; Hendricks & Weltin, 1976), whilst others describe the anatomical modifications of the genital tract of the fetus after treatment of mothers during embryonic sexual differentiation (Greene, Burrill & Ivy, 1940; Marois, 1968). In the present study we have investigated the effects of oestrogen treatment of mothers on the genital morphology of the rat fetus at term and of infant and adult offspring, and examined the consequences of treatment on reproductive function. The activity of the synthetic oestrogen, RU 2858 (moxestrol), was compared to that of oestradiol.

    10 February 20201 EMA/PRAC/8637/2020 Pharmacovigilance Risk Assessment Committee (PRAC) PRAC recommendations on signals Adopted at the 13-16 January 2020 PRAC meeting This document provides an overview of the recommendations adopted by the Pharmacovigilance Risk Assessment Committee (PRAC) on the signals discussed during the meeting of 13-16 January 2020 (including the signal European Pharmacovigilance Issues Tracking Tool [EPITT]2 reference numbers). PRAC recommendations to provide supplementary information are directly actionable by the concerned marketing authorisation holders (MAHs). PRAC recommendations for regulatory action (e.g. amendment of the product information) are submitted to the Committee for Medicinal Products for Human Use (CHMP) for endorsement when the signal concerns Centrally Authorised Products (CAPs), and to the Co-ordination Group for Mutual Recognition and Decentralised Procedures – Human (CMDh) for information in the case of Nationally Authorised Products (NAPs). Thereafter, MAHs are expected to take action according to the PRAC recommendations. When appropriate, the PRAC may also recommend the conduct of additional analyses by the Agency or Member States. MAHs are reminded that in line with Article 16(3) of Regulation No (EU) 726/2004 and Article 23(3) of Directive 2001/83/EC, they shall ensure that their product information is kept up to date with the current scientific knowledge including the conclusions of the assessment and recommendations published on the European Medicines Agency (EMA) website (currently acting as the EU medicines webportal). For CAPs, at the time of publication, PRAC recommendations for update of product information have been agreed by the CHMP at their plenary meeting (27-30 January 2020) and corresponding variations will be assessed by the CHMP.

  • MINI-REVIEW Sequence to Structure Approach Of
    DOI:http://dx.doi.org/10.7314/APJCP.2015.16.6.2161 Sequence to Structure Approach of Estrogen Receptor Alpha and Ligand Interactions MINI-REVIEW Sequence to Structure Approach of Estrogen Receptor Alpha and Ligand Interactions Aekkapot Chamkasem1, Waraphan Toniti2* Abstract Estrogen receptors (ERs) are steroid receptors located in the cytoplasm and on the nuclear membrane. The sequence similarities of human ERα, mouse ERα, rat ERα, dog ERα, and cat ERα are above 90%, but structures of ERα may different among species. Estrogen can be agonist and antagonist depending on its target organs. This hormone play roles in several diseases including breast cancer. There are variety of the relative binding affinity (RBA) of ER and estrogen species in comparison to 17β-estradiol (E2), which is a natural ligand of both ERα and ERβ. The RBA of the estrogen species are as following: diethyl stilbestrol (DES) > hexestrol > dienestrol > 17β-estradiol (E2) > 17- estradiol > moxestrol > estriol (E3) >4-OH estradiol > estrone-3-sulfate. Estrogen mimetic drugs, selective estrogen receptor modulators (SERMs), have been used as hormonal therapy for ER positive breast cancer and postmenopausal osteoporosis. In the postgenomic era, in silico models have become effective tools for modern drug discovery. These provide three dimensional structures of many transmembrane receptors and enzymes, which are important targets of de novo drug development. The estimated inhibition constants (Ki) from computational model have been used as a screening procedure before in vitro and in vivo studies.

  • Oral Contraceptives, Combined
    ORAL CONTRACEPTIVES, COMBINED 1. Exposure Combined oral contraceptives consist of the steroid hormone oestrogen in combi- nation with a progestogen, taken primarily to prevent pregnancy. The same hormones can also be used in other forms for contraception. Combined oral contraceptive pills generally refer to pills in which an oestrogen and a progestogen are given concurrently in a monthly cycle. In contrast, a cycle of sequential oral contraceptive pills includes oestrogen-only pills followed by five to seven days of oestrogen plus progestogen pills. Sequential oral contraceptive pills were removed from the consumer market in the late 1970s; they are covered in an IARC monograph (IARC, 1979, 1987). Combined oral contraceptives are thus usually administered as a pill containing oestrogen and progestogen, which is taken daily for 20–22 days, followed by a seven-day pill-free interval (or seven days of placebo), during which time a withdrawal bleed is expected to occur. The most commonly used oestrogen is ethinyloestradiol, although mestranol is used in some formulations. The pro- gestogens most commonly used in combined oral contraceptives are derived from 19-nor- testosterone and include norethisterone, norgestrel and levonorgestrel, although many others are available (Kleinman, 1990) (see Annex 2, Table 1). Chemical and physical data and information on the synthesis, production, use and regulations and guidelines for hormones used in combined oral contraceptives are given in Annex 1. Annex 2 (Table 1) lists the trade names of many contemporary combined oral contraceptives with their formulations.
