  Synthesis and biological evaluation of 3-amino-2-pyrones as selective cyclooxygenase-1 (COX-1) inhibitors

  摘要：

  A group of 3-amino-2-pyrones were synthesized and their biological activities were evaluated for inhibiting cyclooxygenase (COX) activity. This study has led to the identification of COX-1-selective inhibitors. Among the tested compounds, the compound 5j exhibited the most potent COX-1 inhibitory activity (IC50 = 19.32 mu g/mL) and COX-1 selectivity index (SI = 41.98). (C) 2013 Qing-Fa Zhou.

  Design, Synthesis, and Structure−Activity Relationship Studies of 3,4,6-Triphenylpyran-2-ones as Selective Cyclooxygenase-2 Inhibitors

  摘要：

  A group of regioisomeric 3,4,6-triphenylpyran-2-ones with a MeSO2 pharmacophore at the paraposition of either a C-3 phenyl or a C-4 phenyl substituent on the central six-membered pyran-2-one ring were prepared and evaluated in vitro for their abilities to inhibit the isozymes COX-1 and COX-2. Structure-activity relationship (SAR) data, acquired by substituent modification at the para-position of the C-6 phenyl ring attached to the central pyranone, showed that 6-(4-methoxyphenyl)-3-(4-methanesulfonylphenyl)-4-phenylpyran-2-one (12e) was the most potent and selective COX-2 inhibitor (COX-2 IC50 = 0.02 muM; COX-1 IC50 > 100 muM) with a high COX-2 selectivity index (SI > 5000) relative to the reference drugs celecoxib (COX-2 IC50 = 0.07 muM; SI = 474) and rofecoxib (COX-2 IC50 = 0.50 muM; SI > 200). 6-(4-Methoxyphenyl)-3-(4-methanesulfonylphenyl)-4-phenylpyran-2-one (12e) was a more potent oral antiinflammatory agent (ID50 = 5.6 mg/kg) than celecoxib (ID50 = 10.8 mg/kg) in a carrageenan-induced rat paw edema assay. In a 4% NaCl-induced abdominal constriction assay, a 5 mg/kg oral dose of 12e exhibited good analgesic activity at different time intervals producing 37.5 and 69% inhibition of writhing at 30 and 60 min, respectively. In contrast, the corresponding 6-(4-methoxyphenyl)-4-(4-methanesulfonylphenyl)-3-phenylpyran-2-one regiosiomer (12o) was a less potent and selective COX-2 inhibitor (COX-2 IC50 = 0.45 muM; SI = 70). A molecular modeling study for 12e indicated that the p-OMe substituent on the C-6 phenyl ring interacts with the COX-2 binding site amino acids Ile(345), Val(349), Leu(359), Leu(531), and Met(535) and that the OMe substituent may be responsible for proper orientation of the C-3 p-SO2Me-phenyl ring within the COX-2 secondary pocket (Gln(192), Arg(513), and Phe(518)). These results show that the COX-2 selectivity and potency of 3,4,6-triphenylpyranone regioisomers can be modulated by appropriate placement of the p-SO2Me pharmacophore on either the C-3 or C-4 phenyl moiety. In addition, electronic properties at the para-position of a C-6 phenyl substituent on the central pyranone ring govern COX-2 inhibitory potency and selectivity by controlling the orientation of the p-SO2Me pharmacophore within the COX-2 secondary pocket.

  Abstract An effective method for the synthesis of vinyl thioethers through the conjugate addition of ethanethiol to electron-deficient alkynes promoted by BF 3 ·Et 2 O has been developed. Electron-deficient internal alkynes react with ethanethiol in this system to yield mainly Z -isomer of vinyl thioether adducts, while electron-deficient terminal alkynes afford mainly E -isomer of vinyl thioether

Reported herein is an efficient rhodium(I)‐catalyzed intermolecular disilylation of a wide array of alkynones with unactivated disilanes.

  炔烃的二甲硅烷基化可以快速进入合成上有用的1,2-双甲硅烷基-烯烃，但目前仅限于以分子内方式反应的活化乙硅烷。本文报道的是大量的炔烃与未活化的乙硅烷的高效铑（I）催化的分子间二烯化反应。重要的是，该反应仅产生反式二甲硅烷基化产物，其选择性鲜见报道。这些二甲硅烷基化产物被转化为令人感兴趣的五环乙烯基硅烷醚，以及其他附加的合成操作。机理研究发现，未反应的乙硅烷在反应条件下容易发生Si-Si活化和交叉反应。

  The substituted benzene derivatives are essential to organic synthesis, medicinal chemistry, and material science. However, the 1,3-di- and 1,3,5-trisubstituted benzenes are far less prevalent in small-molecule drugs than other substitution patterns, likely due to the lack of robust, efficient, and convenient synthetic methods. Here, we report a Mo-catalyzed intermolecular deoxygenative benzene-forming

  取代苯衍生物对有机合成、药物化学和材料科学至关重要。然而，1,3-二-和 1,3,5-三取代苯在小分子药物中的普遍性远低于其他取代模式，这可能是由于缺乏稳健、高效和方便的合成方法。在这里，我们报告了一种 Mo 催化的分子间脱氧苯形成反应，该反应是现成的炔酮和烯丙基胺的反应。通过使用市售的钼催化剂，以高达 88% 的收率获得了多种不对称和未官能化的 1,3-二和 1,3,5-三取代苯。通过生物活性分子的合成转化、放大合成和衍生化进一步说明了该方法的合成潜力。初步的机理研究表明，这种苯形成过程可能通过钼催化的氮杂迈克尔加成/[1,5]-氢化物转移/环化/芳构化级联进行。该策略不仅为各种间位取代的苯衍生物，但也证明了钼催化在具有挑战性的分子间脱氧交叉偶联反应中的潜力。

  A stereoselective and effective method for the synthesis of vinyl thioethers has been developed. This method is based on the Michael addition of ethanethiol to various alkynyl ketones using 10 mol% of tributylphosphine as catalyst. Most of alkynyl ketones react with ethanethiol in this system to yield mainly Z-isomer of vinyl thioether adducts, only in one case mainly E-isomer of vinyl thioether adducts was observed.
