  摘要：

  死亡相关的蛋白激酶相关的凋亡诱导激酶2（DRAK2）是一种丝氨酸/苏氨酸激酶，在多种细胞死亡信号传导途径中起关键作用。发现抑制DRAK2可有效保护胰岛β细胞免于凋亡，因此DRAK2抑制剂代表了治疗糖尿病的有前途的治疗策略。目前仅知道靶向DRAK2的化学实体很少。我们进行了高通量筛选，并将化合物4鉴定为中度DRAK2抑制剂，IC50值为3.15μM。随后对命中化合物4的SAR研究导致开发出新型的benzofuran-3（2H）-DRAK2抑制剂系列，具有针对26种所选激酶的增强的效能和有利的选择性。重要的是，大多数有效化合物40（IC50 = 0.33μM）和41（IC50 = 0。发现25μM）以剂量依赖性方式保护胰岛β细胞免于凋亡。这些数据支持以下观点：DRAK2的小分子抑制剂代表了治疗糖尿病的有前途的策略。

• Synthesis and Insect Antifeedant Activity of Aurones against <i>Spodoptera litura</i> Larvae

  A series of aurones were prepared from various phenols via phenoxy acetic acids and coumaranones and evaluated for insect antifeedant activity against the common cutworm (Spodoptera litura). The naturally occurring aurone was most active at an ED50 of 0.12 mu mol/cm(2). The synthetic precursor, coumaranones, showed that the introduction of methoxyl and methyl groups to the benzene ring increased insect antifeedant activity. Similarly, the tested aurones showed that the introduction of methoxyl group to the A and/or B rings increased the insect antifeedant activity, but 4,5,6- and 3',4',5'-trisubstituted compounds did not show this activity in this test. The hydroxylation of aurones in the B ring should be disadvantageous for insect antifeedant activity against S. litura. Although the melting points did not correlate well with the insect antifeedant activity, compounds that were nearly inactive had high melting points. A significant correlation was noted between biological activity (pED(50)) and a hydrogen-bonding parameter calculated from the R-f value obtained from SiOH thin-layer chromatography and a lipophilicity parameter (log k) calculated from the retention time in ODS high-performance liquid chromatography. The respective correlation coefficients (r) were -0.83 and -0.70. The introduction of alkoxy and alkyl groups along with adequate hydrogen bonding seems to contribute to the antifeedant activity of the compounds tested.

  kinase-related apoptosis-inducing kinase-2 (DRAK2) is a serine/threonine kinase that plays a key role in a wide variety of cell death signaling pathways. Inhibition of DRAK2 was found to efficiently protect islet β-cells from apoptosis and hence DRAK2 inhibitors represent a promising therapeutic strategy for the treatment of diabetes. Only very few chemical entities targeting DRAK2 are currently known. We carried
