Discovery of a Rapidly Metabolized, Long-Acting β2 Adrenergic Receptor Agonist with a Short Onset Time Incorporating a Sulfone Group Suitable for Once-Daily Dosing
摘要:
A series of novel, potent, and selective human beta(2) adrenoceptor agonists incorporating a sulfone moiety on the terminal right-hand-side phenyl ring of (R)-salmeterol is presented. Sulfone 10b had salmeterol-like potency and selectivity profile, long duration of action on guinea pig trachea, and longer than salmeterol duration of action in vivo, suitable for once-daily dosing. It had lower than salmeterol oral absorption in rat, lower bioavailability in rat and dog, and a high turnover in human hepatocytes. It was metabolized in human hepatocytes by hydroxylation, oxidation, cleavage, and conjugation; most of the metabolites would be expected to have reduced or no beta(2) activity. The 4-biphenylsulfonic acid was identified as a crystalline, non-hygroscopic salt of 10b, suitable for inhaled delivery. Furthermore, it was free of any genetic toxicity issues and was considered as a backup to vilanterol.

interest in the discovery of inhibitors as biological tools and, potentially, therapeutics. Although several PRMT4 inhibitors have been reported, most display poor selectivity against other members of the PRMT family of methyl transferases. Herein, we report the structure‐based design of a new class of alanine‐containing 3‐arylindoles as potent and selective PRMT4 inhibitors, and describe key structure–activity

Compounds of formula (I) and salts, solvates, and physiologically functional derivatives thereof, useful for the prophylaxis or treatment of a clinical condition for which a selective β2-adrenoreceptor agonist is indicated, for example asthma or chronic obstructive pulmonary disease (COPD).
Herein, we report a borane-promoted reductive deoxygenation coupling reaction to synthesize sulfides. This reaction features excellent functional group compatibility, high efficiency, broad substrate scope, and application in late-stage functionalization of biomolecules. Preliminary mechanistic studies suggest diaryl sulfides are the intermediates of this reaction. Moreover, the real active aryl sulfide
在此,我们报告了一种硼烷促进的还原脱氧偶联反应来合成硫化物。该反应具有官能团相容性好、效率高、底物适用范围广等特点,可应用于生物分子的后期官能化。初步机理研究表明二芳基硫化物是该反应的中间体。此外,真正的活性芳基硫阴离子可以在B 2 pin 2的帮助下原位生成,并通过协同的S N 2 途径与烷基甲苯磺酸盐反应。
