The Contraception and Reproductive Health Branch of the NICHD supports a Chemical Synthesis Facility (CSF) that provides services central to the Branch's programs to develop safe and effective contraceptive agents. This Facility provides the Government with drugs, chemicals, chemical intermediates, steroids, and optically pure and/or resolved unnatural amino acids possessing >99% enantipmeric excess, which are either commercially unavailable or unduly expensive, for further contraceptive development by the Government. Specific Aims: The areas of chemical synthesis include: 1) orally active steroids, including;{ estrogens without 17 -ethynyla1cohol, orally active and long ¿acting androgens, e.g., testosterone bucyclate and 7cm, 11 p..dimethyl-19~nortestosterone bucyclate & undecanoate, orally active 7&a-methyI-19¿nortestosterone (MENT) analogs, and progesterone receptor modulators (PRM),e.g., CDB-2914, 21-suhstituted analogs, e.g., CDB4124 (2nd generation) and novel derivatives (3rd generation) in combination of substititon at CllB-4-aryl and C17&a; 2) steroid haptens linked to bovine serum a1bumin as well as to histamine conjugates for the development of radioimmunoassay (RIA.); 3)radiolabeled compounds for RIA as tracers and for metabolism studies; 4) heterocyclic compounds including seconucleosides and hexahydroindenopyridine diastereomers ; and 5) alkylated iminosugars. The Contractor maintains and operate a Chemical Synthesis Facility (CSF) capable of (l) rapidly synthesizing laboratory scale quantities (1 to 5 grams) of specific chemical compounds required for initial contraceptive investigation in small animals, (2) synthesizing relatively larger quantities (up to <1 kg) of Some drugs for comprehensive antifertility testing by the Government, including preclinical and clinical studies under current Good Manufacturing Practices (cGMP); (3) synthesizing chemicals and/or chemical intermediates (up to < 1 kg) for use in other ongoing chemical. peptide and related contracts and other synthetic chemical contract programs; and (4) radiolabeled synthesis of compounds using 3H, I~C and 1251 for pharmacokinetics and metabolism studies.

避孕和生殖健康处支持一个化学合成设施，该设施为该处开发安全有效避孕药物的方案提供核心服务。该设施向政府提供药品、化学品、化学中间体、类固醇以及具有超过99%对映体过量的光学纯和/或已分解的非天然氨基酸，供政府进一步开发避孕药具之用，这些药品要么在商业上无法获得，要么价格过高。
