  摘要：

  The synthesis and biological properties of 35 2-(acylamino)oxazoles are described. The majority of the compounds inhibit the release of slow-reacting substance of anaphylaxis (SRS-A) in vitro from sensitized guinea pig chopped lung. In addition, several of the compounds inhibited the release of SRS-A from passively sensitized human chopped lung and protected guinea pigs from the effects of anaphylaxis in a modified Herxheimer test.

  Because of the double-edged nature of NO, the development of isoform-selective NOS substrates is a highly desirable goal. Given the striking similarity in the heme active sites of the three NOS isoforms, it presents an challenging problem. Several N-aryl-N'-hydroxyguanidines have recently been shown as substrates that are selective for iNOS over nNOS. Here, we report the first success that 3 is a good

  由于NO的双重优势，开发同工型选择性NOS底物是一个非常理想的目标。鉴于三种NOS亚型的血红素活性位点具有惊人的相似性，因此提出了一个具有挑战性的问题。最近已显示出几种N-芳基-N'-羟基胍作为对iNOS的选择性底物，而不是对nNOS的底物。在这里，我们报告的第一个成功是3是iNOS的nNOS（70％的NOHA活性，K（m）约为40 +/- 6 microM）的良好底物。

  method for the synthesis of cyanamides from dithiocarbamate salts via a double desulfurization strategy using molecular iodine is disclosed. Dithiocarbamates, by the action of iodine yield isothiocyanates in situ, which on treatment with aqueous NH3 give thioureas. The thioureas so generated undergo further oxidative desulfurization with I2 giving corresponding cyanamides in good yields. Environmental

  In a one-pot strategy we have achieved an efficient method for the synthesis of organic cyanamides starting from dithiocarbamic acid salts/amines. In this strategy the in situ generated alkyl or aryl isothiocyanates, obtained by the desulfurization of dithiocarbamic acid salts with diacetoxyiodobenzene (DIB) react with aqueous ammonia forming alkyl or aryl thiourea which on subsequent oxidative desulfurization

  在单罐策略中，我们已经获得了一种从二硫代氨基甲酸盐/胺开始合成有机氰胺的有效方法。在这种策略中，原位生成的烷基或芳基异硫氰酸酯是通过将二硫代氨基甲酸盐与二乙酰氧基碘苯（DIB）脱硫而获得的，与氨水反应生成烷基或芳基硫脲，随后再用DIB进行氧化脱硫，从而形成了相应的氰胺。产量。温和的反应条件，较短的反应时间，对环境有益的方案以及所需产物的容易分离，使得本方法学成为制备各种有机氰胺的合适替代方法。

  The synthesis of cyanamides and tetrazoles from isothiocyanates through tandem reaction using cobalt catalyst has been demonstrated. In the case of tetrazole preparation, the reaction involved addition/desulfurization/nucleophilic addition/electrocyclization, whereas aromatic cyanamides were constructed from isothiocyanates through addition/desulfurization. Cheap cobalt sulfate was used for the synthesis
