we adopted 3-chlorobenzenesulfonyl derivative 20a as a lead compound for structural development. Among the synthesized compounds, 3-trifluoromethyl derivative 32 exhibited the most potent PR-antagonistic activity, with high binding affinity for PR and selectivity over androgenreceptor (AR). It is structurally distinct from other nonsteroidal PR antagonists, including cyanopyrrole derivatives, and

This invention pertains generally to the field of therapeutic compounds, and more particularly, to certain bicyclosulfonyl acid (BCSA) compounds which act as inhibitors of Tumour Necrosis Factor-α Converting Enzyme (TACE). The compounds are useful in the treatment of conditions mediated by TNF-α, such as rheumatoid arthritis; inflammation; psoriasis; septic shock; graft rejection; cachexia; anorexia; congestive heart failure; post ischaemic reperfusion injury; inflammatory disease of the central nervous system; inflammatory bowel disease; insulin resistance; HIV infection; cancer; chronic obstructive pulmonary disease (COPD); and asthma. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, in the inhibition of TACE, and in the treatment of conditions that are ameliorated by the inhibition of TACE.

industry. A one-step synthesis catalyzed by a copper salt was developed using stable solid commodity chemicals in sulfolane or, alternatively, in green solvents such as γ-valerolactone, iPrOAc, or nBuOAc with acetic acid. The method tolerated diverse functional groups commonly presented in current medicines and drug intermediates. The mechanistic study showed a radical coupling pathway between the sulfonyl
官能化芳基磺酰胺是制药工业中的重要组成部分。使用稳定的固体商品化学品在环丁砜中或在绿色溶剂(如 γ-戊内酯、 i PrOAc 或n BuOAc 与乙酸)中开发了由铜盐催化的一步合成。该方法耐受当前药物和药物中间体中常见的多种官能团。机理研究表明,磺酰基和苯胺自由基之间的自由基偶联途径分别通过使用 K 2 S 2 O 8和铜催化剂。

photoexcitation of aryl(hetero)diazonium salts and sulfonamides enabled this strategy under visible-light irradiation through an EDA complex used to carry out a one-step synthesis without a catalyst. This approach tolerated various functional groups of primary sulfonamides and (hetero)aryl diazonium salts, frequently found in modern medications and pharmacological intermediates. This method also enabled
