  摘要：

  报道了一种简便的合成 2,3,6-三取代-5,6-二氢咪唑并[2,1- b ]噻唑的方法。通过用1,1'-硫代羰基二咪唑处理树脂结合的二胺形成树脂结合的环状硫脲，然后与α-卤代酮反应生成树脂结合的异硫脲。树脂结合异硫脲的 HF 处理导致产物裂解并同时形成烯胺键。这导致以高产率和纯度形成2,3,6-三取代-5,6-二氢咪唑并[2,1- b ]噻唑。

  Identification of 5,6-dihydroimidazo[2,1- b ]thiazoles as a new class of antimicrobial agents

  摘要：

  In an effort to develop novel antimicrobial agents against drug-resistant bacterial infections, 5,6-dihydroimidazo[2,1-b]thiazole compounds were synthesized and tested for their antimicrobial activity. Eight compounds comprised by two sub-scaffolds were identified as hits against methicillin-resistant Staphylococcus aureus (MRSA). These hits were modified at 6-position by replacing (S)-6 to (R)-6 configuration and the (R)-isomers increased their antimicrobial activities by two-fold. The most active compound showed a MIC90 value of 3.7 mu g/mL against MRSA in a standard microdilution bacterial growth inhibitory assay. This compound protected wax moth worms against MRSA at a dose of 5x MIC using a worm infectious model. This compound also exhibited inhibition of DNA gyrase activity in a DNA gyrase supercoil assay, suggesting the 5,6-dihydroimidazo[2,1-b]thiazoles may target DNA gyrase for the antimicrobial action.
