  Discovery of Potent and Selective SH2 Inhibitors of the Tyrosine Kinase ZAP-70

  摘要：

  A series of 1,2,4-oxadiazole analogues has been shown to be potent and selective SH2 inhibitors of the tyrosine kinase ZAP-70, a potential therapeutic target for immune suppression. These compounds typically are 200-400-fold more potent than the native, monophosphorylated tetrapeptide sequences. When compared with the high-affinity xi-1-ITAM peptide (Ac-NQL-pYNELNLGRREE-pYDVLD-NH2, wherein pY refers to phosphotyrosine) some of the best 1,2,4-oxadiazole analogues are approximately 1 order of magnitude less active. This series of compounds displays an unprecedented level of selectivity over the closely related tyrosine kinase Syk, as well as other SH2-containing proteins such as Src and Grb2. Gel shift studies using a protein construct consisting only of C-terminal ZAP-70 SH2 demonstrate that these compounds can effectively engage this particular SH2 domain.

  的硝基苯并衍生物Ñ ' -羟基脒如吲哚胺-2,3-双加氧酶1的有效抑制剂

  摘要：

  通过犬尿氨酸途径的色氨酸代谢被认为是免疫耐受的关键机制。吲哚胺2,3-二加氧酶1（IDO1）在免疫系统的色氨酸分解代谢中起关键作用，它也被认为是治疗与犬尿氨酸途径相关的癌症和其他疾病的重要治疗靶标。在这项研究中，合成了一系列N'-羟基苯甲酰胺（1）和N'-羟基-2-苯基乙酰胺二酰亚胺（2）的硝基苯并呋喃衍生物，并通过体外和细胞酶活性试验测试了它们对人IDO1酶的抑制活性。 。通过优化可以确定有效的化合物1d，2i和2k（IC 50  = 39–80 nM），它们是IDO1酶的竞争性或非竞争性抑制剂。这些化合物 在MDA-MB-231细胞中也显示出纳摩尔范围（IC 50 = 50–71 nM）的IDO1抑制能力，而细胞毒性没有/可以忽略不计。有效化合物对IDO1酶的选择性比色氨酸2,3-二加氧酶（TDO）酶强（312–1593倍），也使其对进一步的免疫治疗应用具有极大的吸引力。
