  Novel Inhibitors of the Nuclear Factor of Activated T Cells (NFAT)-Mediated Transcription of .beta.-Galactosidase: Potential Immunosuppressive and Antiinflammatory Agents

  摘要：

  The preparation of a series of quinazoline-2,4-diones, 1-3, and pyrrolo[3,4-d]pyrimidine-2,4-diones, 4-8 is described. A small number of quinazolinedione analogs were identified from random screening to possess low micromolar (1.3-4.4 mu M) potency in the nuclear factor of activated T cells-1-regulated beta-galactosidase expression assay. An expanded analog search resulted in identifying pyrrolopyrimidinedione 4b which is 5-10-fold (0.26 mu M) more potent than the quinazolinediones. Replacement of the benzyl group with naphthyl led to greater potency and conformationally restricted analogs 4u-w. The naphthyl and acenaphthyl analogs are 10-100 times more potent inhibitors of beta-galactosidase expression than 4b. Binding affinity data for displacement of radiolabeled 4s from Jurkat cell membranes reflected an excellent correlation with the IC50 value for inhibition of beta-galactosidase activity. These products, whose structure-activity relationships are discussed, are of interest as potential agents for preventing interleukin-2 gene transcription.
