    Fragment based search for small molecule inhibitors of HIV-1 Tat-TAR
    摘要:
    Basic molecular building blocks such as benzene rings, amidines, guanidines, and amino groups have been combined in a systematic way to generate ligand candidates for HIV-1 TAR RNA. Ranking of the resulting compounds was achieved in a fluorimetric Tat-TAR competition assay. Although simple molecules such as phenylguanidine are inactive, few iteration steps led to a set of ligands with IC50 values ranging from 40 to 150 mu M. 1,7-Diaminoisoquinoline 17 and 2,4,6-triaminoquinazoline 22 have been further characterized by NMR titrations with TAR RNA. Compound 22 is bound to TAR at two high affinity sites and shows slow exchange between the free ligand and the RNA complex. These results encourage investigations of dimeric ligands built from two copies of compound 22 or related heterocycles. (C) 2014 Elsevier Ltd. All rights reserved.

    喹唑啉的 1,2,3-三唑衍生物通过将 RNF168 拴系到 SQSTM1/P62 表现出抗肿瘤活性
    摘要:
    喹唑啉及其衍生物在潜在抗肿瘤药物的开发中备受关注。在这里,我们在 C6 位合成了一系列喹唑啉的 1,2,3-三唑衍生物,并评估了它们在各种人类癌细胞系中的细胞毒活性。我们发现化合物5a对 HCT-116 细胞的细胞毒性最强(IC 50 , 0.36 μM)。目标分析发现5a直接与自噬相关蛋白 SQSTM1/P62 和 E3 连接酶 RNF168 结合,促进它们的相互作用。一致地,5a处理诱导 RNF168 介导的 H2A 泛素化减少并损害同源重组介导的 DNA 修复,从而增加 HCT-116 对 X 射线辐射的敏感性。而且,5a以剂量依赖性方式抑制小鼠异种移植肿瘤的生长。总之,基于其促进 P62/RNF168 相互作用的作用,喹唑啉5a的 1,2,3-三唑衍生物可用作肿瘤治​​疗的新型化合物。
