  多数已知的合成杂环化合物的方法都具有缺点，例如反应时间长和条件苛刻。我们已经开发了一种新的，相当简单且有效的方法，该方法使用乙二膦酸（HEDP）作为“绿色催化剂”来合成水中的许多甘氨酰和乙内酰脲。因此，在HEDP的存在下，尿素与1，2-二羰基化合物的缩合反应首次出现。同样基于NMR研究，提出了这些反应的化学过程，这是逐步的。已经确定，使用HEDP合成乙二醇脲和乙内酰脲的最佳条件为：温度80°C-90°C，40-20分钟，尿素和HEDP的比例为1：1。在所有情况下，

  The instant invention provides compositions for downmodulation or upmodulation of the immune response. For example, constructs comprising an exposed surface having attached to it i) an antigen-binding portion of an antibody that binds to a CTLA-4 or CD28 molecule that is expressed on a T cell of the subject, and ii) an MHC molecule selected from the group consisting of: a class II molecule that is syngeneic to the subject, a class I molecule that is syngeneic to the subject, and a class I molecule that is allogeneic to the subject are provided. Methods of using the molecules of the invention in downmodulation or upmodulation of the immune response are also provided. Also provided are methods of downmodulating an immune response in a subject comprising causing a cell of the subject to express an antigen-binding portion of an antibody that binds a CTLA-4 or CD28 molecule that is expressed on a T cell of the subject, such that the immune response in the subject is downmodulated. Methods of preparing an allogeneic cell for transplantation and methods of transplanting engineered allogeneic cells are also provided.

  known methods for the synthesis of heterocyclic compounds have disadvantages, such as a long reaction time and aggressive conditions. We have developed a new, rather simple and efficient method for the synthesis of a number of glycoluryls and hydantoins in water using a etidronic acid (HEDP) as “Green catalyst.” So, for the first time, the condensation reaction of ureas with 1, 2‐dicarbonyl compounds
