  通过混合安息香-咪唑并硫醇途径制备异构5（6）-（4-吡啶基）-和6（5）-（4-取代苯基）-2,3-二氢咪唑并[2,1-b]噻唑。通过光谱比较将它们的结构分配给已建立取代模式的化合物。通过X射线分析确认了结构分配。通过佐剂关节炎大鼠测定法对化合物的抗炎活性的检查显示，一个类似系列的化合物的功效显着高于其异构体。在恶唑酮诱导的接触敏感性模型中反映出，这种选择性与刺激细胞介导的免疫能力平行。提出了需要至少三个相互作用位点的药物-受体复合物。

  A series of substituted 5,6-diaryl-2,3-dihydroimidazo[2,1-b]thiazoles were synthesized and evaluated in the rat adjuvant-induced arthritis and mouse oxazolone-induced contact sensitivity assays to determine the potential of these compounds for use as immunoregulatory antiinflammatory agents. This class of compounds was derived by combining salient structural features of the antiinflammatory agent flumizole and the immunoregulatory drug levamisole. Unlike the latter two, a number of compounds in the target series were found to possess the desired combination of activities. Exploration of structure-activity relationships in the adjuvant-induced arthritic rat assay revealed that optimal potency was exhibited by symmetrically substituted 5,6-diaryl compounds having one of the following alkyl heteroatom or halogen functions at the para position: methoxy, ethoxy, methylthio, N-ethyl-N-methylamino, fluoro, or chloro. Scrambling of these two substituent classes to yield the asymmetrically substituted 5,6-diaryl compounds resulted in potent activity only with the 5-alkyl heteroatom, 6-halo-substituted regioisomers. However in the oxazolone-induced contact sensitivity assay, no consistent relationship of variation in activity with structural change was apparent. The initial target compound 5,6-bis(4-methoxyphenyl)-2,3-dihydroimidazo[2,1-b]thiazole (1) was compared with its progenitors in additional models of inflammation and immunoregulation.
