  The structure–activity relationship of the series of non-peptide small antagonists for p56lck SH2 domain

  摘要：

  The antagonists for the SH2 domain are regarded as novel therapeutic candidates for cancer, autoimmune disease, and chronic inflammatory disease. Previously, we identified rosmarinic acid (alpha-o-caffeoyl-3,4-dihydroxyphenyl-lactic acid; RosA) from Prunella vulgaris as an antagonist for the p56lck SH2 domain by screening natural products. RosA not containing phosphotyrosine surrogate had a considerable inhibitory activity for T-cell antigen receptor (TCR)-induced interleukin (IL)-2 expression, and subsequent T-cell proliferation in vitro cell assay. To investigate the structure-activity relationship of RosA and to identify a novel p56lck SH2 antagonist with more potent in vitro T-cell inhibitory activity, we synthesized several analogs of RosA by using rational design. All synthesized compounds were tested in vitro binding activity for the SH2 domain and in vitro T-cell inhibitory activity. All four hydroxyl groups of RosA were essential for binding with the p56lck SH2 domain and T-cell inhibitory activity. Unexpectedly, conformationally less constrained analogs 4 and 9 showed a more potent binding affinity for the SH2 domain than that of RosA, and chirality of the analog did not play an important role in protein binding. We successfully identified several RosA analogs with a more potent T-cell inhibitory activity than that of RosA. Overall results revealed important structural requirements of the p56lck SH2 antagonists for in vitro T-cell inhibitory activity and in vitro protein binding activity. (C) 2006 Elsevier Ltd.

  氯丁酰胺及其相关化合物抑制淀粉样蛋白β聚集的构效关系。

  摘要：

  阿尔茨海默氏病（AD）是一种神经退行性疾病，其特征是淀粉样β蛋白（Aβ）聚集。Aβ通过β折叠形成聚集，并诱导针对神经元细胞的细胞毒性。因此，天然存在的化合物抑制Aβ聚集是治疗AD的有前途的策略。我们已经报道了具有两个或多个邻苯二酚部分的咖啡酰奎尼酸和苯乙酮类糖苷强烈抑制了Aβ聚集。从可可豆（Theobroma cacao L.）分离的含有两个邻苯二酚部分的环丙酰胺（1）被认为对Aβ聚集具有预防作用。为了研究氯丁酰胺（1）抑制Aβ聚集的构效关系，我们通过1-DOPA，d-DOPA，l-酪氨酸，或l-苯丙氨酸和咖啡酸，对香豆酸或肉桂酸，化合物12和13衍生自1。在测试的化合物1-13中，含有一个或两个邻苯二酚部分的化合物表现出强的抗聚集活性，而非儿茶酚类相关化合物几乎没有活性。这表明至少一个儿茶酚部分对于抑制Aβ42聚集是必不可少的，并且该活性根据儿茶酚部分的数目而增加。因此，clovamid

  the structure-activity relationship of clovamide (1) for the inhibition of Aβ aggregation, we synthesized 1 and related compounds 2-11 through reaction between l-DOPA, d-DOPA, l-tyrosine, or l-phenylalanine and caffeic acid, p-coumaric acid, or cinnamic acid, and compounds 12 and 13 were derived from 1. Among tested compounds 1-13, those containing one or two catechol moieties exhibited potent anti-aggregation
