  N-Hydroxybenzimidazole inhibitors of ExsA MAR transcription factor in Pseudomonas aeruginosa: In vitro anti-virulence activity and metabolic stability

  摘要：

  ExsA is a multiple adaptational response (MAR) transcription factor, regulating the expression of a virulence determinant, the type III secretion system (T3SS) in Pseudomonas aeruginosa. Non-cytotoxic, non-antibacterial N-hydroxybenzimidazoles were identified as effective inhibitors of ExsA-DNA binding, and their potential utility as anti-virulence agents for P. aeruginosa was demonstrated in a whole cell assay. Select N-hydroxybenzimidazole inhibitors were stable in an in vitro human liver microsomal assay. (C) 2010 Elsevier Ltd. All rights reserved.

  Synthesis of novel tetrahydroisoquinoline bronchodilators

  摘要：

  The synthesis and bronchorelaxing effects of a series of novel tetrahydroisoquinoline amides are described. The compounds were evaluated for their ability to relax LTD4 contracted isolated human small airways ex-vivo. Several compounds demonstrated highly efficacious bronchorelaxing properties. Cinnamide 71 was selected for further studies and constitutes a promising candidate as a novel bronchorelaxing agent for the treatment of pulmonary disorders. (C) 2010 Elsevier Ltd.

  inaccessible with existing carbonyl desaturation protocols. Product inhibition is overcome through ligand-promoted preferential activation of C(sp3)–H bonds over C(sp2)–H bonds or a tandem dehydrogenation or vinyl C–H alkynylation sequence. The dehydrogenation reaction is compatible with molecular oxygen as the terminal oxidant.

  通过亚甲基 C-H 活化将烷基链脱氢转化为烯烃仍然是一个重大挑战。我们报道了两类吡啶-吡啶酮配体，它们通过钯催化的β-亚甲基C-H活化羧酸实现不同的脱氢反应，从而直接合成α,β-不饱和羧酸或γ-亚烷基丁烯内酯。这对反应的定向性质允许在其他烯醇化官能团（例如酮）存在下对羧酸进行化学选择性脱氢，从而提供现有羰基去饱和方案无法实现的化学选择性。通过配体促进的 C(sp 3 )–H 键相对于 C(sp 2 )–H 键的优先激活或串联脱氢或乙烯基 C–H 炔基化序列来克服产物抑制。脱氢反应与分子氧作为末端氧化剂相容。
