  • Progestin - Wikipedia, the Free Encyclopedia
    Progestin - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Progestin From Wikipedia, the free encyclopedia A progestin is a synthetic[1] progestogen that has progestinic effects similar to progesterone. [2] The two most common uses of progestins are for hormonal contraception (either alone or with an estrogen), and to prevent endometrial hyperplasia from unopposed estrogen in hormone replacement therapy. Progestins are also used to treat secondary amenorrhea, dysfunctional uterine bleeding and endometriosis, and as palliative treatment of endometrial cancer, renal cell carcinoma, breast cancer, and prostate cancer. High-dose megestrol acetate is used to treat anorexia, cachexia, and AIDS-related wasting. Progesterone (or sometimes the progestin dydrogesterone or 17α-hydroxyprogesterone caproate) is used for luteal support in IVF protocols, questionably for treatment of recurrent pregnancy loss, and for prevention of preterm birth in pregnant women with a history of at least one spontaneous preterm birth.[3] They are also used in judicial chemical castration of sex offenders as well as a treatment options for those suffering from paraphilia.

Rogowsky Director of Operations Karen Laney-Cummings Director of Industries Address all communications to Secretary to the Commission United States International Trade Commission Washington, DC 20436 U.S. International Trade Commission Washington, DC 20436 www.usitc.gov Advice Concerning the Addition of Certain Pharmaceutical Products and Chemical Intermediates to the Pharmaceutical Appendix to the Harmonized Tariff Schedule of the United States Investigation No. 332--476 Publication 3883 September 2006 This report was prepared principally by Office of Industries Philip Stone, Project Leader With assistance from Elizabeth R. Nesbitt Primary Reviewers David G. Michels, Office of Tariff Affairs and Trde Agreements, John Benedetto, and Nannette Christ, Office of Economics Administrative Support Brenda F. Carroll Under the direction of Dennis Rapkins, Chief Chemicals and Textiles Division ABSTRACT Under the Pharmaceutical Zero-for-Zero Initiative, which entered into force in 1995, the United States and its major trading partners eliminated tariffs on many pharmaceuticals, their derivatives, and certain chemical intermediates used to make pharmaceuticals. The U.S. list of pharmaceutical products and chemical intermediates eligible for duty-free treatment under the agreement is given in the Pharmaceutical Appendix to the Harmonized Tariff Schedule of the United States. The Pharmaceutical Appendix is periodically updated to provide duty relief for additional such products, including newly developed pharmaceuticals. This report provides advice on the third update to the agreement, in which approximately 1,300 products are proposed to receive duty-free treatment.

  • Fluorine-Substituted Tanaproget As a Progesterone Receptor Imaging Agent for Positron Emission Tomography
    中国科技论文在线 http://www.paper.edu.cn 1096 Bioconjugate Chem. 2010, 21, 1096–1104 Development of [F-18]Fluorine-Substituted Tanaproget as a Progesterone Receptor Imaging Agent for Positron Emission Tomography Jae Hak Lee,‡ Hai-bing Zhou,†,‡ Carmen S. Dence,§ Kathryn E. Carlson,‡ Michael J. Welch,§ and John A. Katzenellenbogen*,‡ Department of Chemistry, University of Illinois at Urbana-Champaign, 600 South Matthews Avenue, Urbana, Illinois 61801, and Mallinckrodt Institute of Radiology, Washington University School of Medicine, 510 South Kingshighway, St. Louis, Missouri 63110. Received February 24, 2010; Revised Manuscript Received March 29, 2010 The level of progesterone receptors (PRs) in breast tumors can be used to guide the selection of endocrine therapies for breast cancer patients. To this end, we have prepared a fluorine-18 labeled analogue of Tanaproget, a nonsteroidal progestin with very high PR binding affinity and low affinity for androgen and glucocorticoid receptors, and have studied its tissue distribution in estrogen-primed rats to evaluate its potential for imaging PR levels by positron emission tomography. 4-[18F]Fluoropropyl-Tanaproget ([18F]9, FPTP) was prepared in three steps, within 140 min at an overall decay-corrected yield of 5% and effective specific activity of >550 Ci/mmol. In biodistribution studies, [18F]9 uptake was high in target tissues at both 1 and 3 h (uterus, 4.55 and 5.26%ID/g; ovary, 2.32 and 2.20%ID/g, respectively) and was cleanly blocked by coinjection of excess unlabeled compound. Uterus to blood and muscle activity ratios were 9.2 and 5.2 at 1 h and 32 and 26 at 3 h, respectively.
