  Discovery of 7-N-Piperazinylthiazolo[5,4-d]pyrimidine Analogues as a Novel Class of Immunosuppressive Agents with in Vivo Biological Activity

  摘要：

  Herein we describe the synthesis and in vitro and in vivo activity of thiazolo[5,4-d]pyrimidines as a novel class of immunosuppressive agents, useful for preventing graft rejection after organ transplantation. This research resulted in the discovery of a series of compounds with potent activity in the mixed lymphocyte reaction (MLR) assay, which is well-known as the in vitro model for in vivo rejection after organ transplantation. The most potent congeners displayed IC50 values of less than 50 nM in this MLR assay and hence are equipotent to cyclosporin A, a clinically used immunosuppressive drug. One representative of this series was further evaluated in a preclinical animal model of organ transplantation and showed excellent in vivo efficacy. It validates these compounds as new promising immunosuppressive drugs.

  An efficient synthesis of a library of 5-amino-thiazolo[4,5-d]pyrimidines is reported. Regioselective displacements of chlorines, as well as regioselective diazotation reactions are described, which allow the introduction of structural diversity on the scaffold by consecutive reactions. Screening of this focused library led to the discovery of SecA inhibitors from Escherichia coli and Staphylococcus
