  Solid-phase synthesis and biological evaluation of a parallel library of 2,3-dihydro-1,5-benzothiazepines

  摘要：

  Solid-phase synthesis of a parallel library of 3'-hydroxy-2,3-dihydrobenzothiazepines has been carried out through [4+3] annulation of alpha,beta-unsaturated ketones with aminothiophenol, using Wang resin as solid support. The synthesized compounds were evaluated for their potential as antibacterial, tumor inhibitors as well as acetyl- and butyrylcholinesterase inhibitors. None of the compounds showed any significant antibacterial activity. However, quite a few compounds showed significant potential as crown gall tumor inhibitors. These results reflect a strong exploratory potential in search of new benzothiazepines as source of anticancer agents. The results of the inhibition of cholinesterase revealed that benzothiazepines have a greater potential as butyrylcholinesterase inhibitors as compared to acetylcholinesterase. Moreover, the substitution of hydroxy group at C-3 in ring A led to increased activity when compared to unsubstituted- and 2'-OH substituted benzothiazepines. (C) 2008 Elsevier Ltd.

  查耳酮作为H1N1神经氨酸酶抑制剂的设计，合成和评估

  摘要：

  基于异寡糖原蛋白（最活跃的天然查尔酮非竞争性神经氨酸酶（NA）抑制剂）设计了一系列查尔酮衍生物（1a – 2i）。分子模型研究表明，异寡糖原蛋白及其设计的类似物占据了NA的430环腔，并与催化位点残基相互作用。合成了有利的衍生物，并评价了其对H1N1病毒的细胞毒性和对细胞病变作用的抑制作用。通过血凝（HA）测定，H1N1-NA抑制和抑制动力学进一步量化了抑制作用。HA分析表明，化合物1e的最低EC 50为1.71 nM。相反，H1N1-NA抑制试验显示化合物1f具有3.58μM的IC 50最佳活性。酶动力学研究表明化合物1f和2f的抑制机理是非竞争性的。

  A series of chalcone derivatives (1a–2i) were designed based on isoliquiritigenin (the most active natural chalcone non-competitive neuraminidase (NA) inhibitor). Molecular modeling studies revealed that isoliquiritigenin and its designed analogs occupied 430-loop cavity of NA and interacted favorably with catalytic site residues. The favorable derivatives were synthesized and evaluated for cytotoxicity
