  基于片段的流感核酸内切酶抑制剂的鉴定

  摘要：

  流感病毒每年造成数百万例严重疾病。疫苗效力的逐年变化，加上新出现的耐药性，有必要开发用于治疗流感感染的新药。一种有吸引力的靶标是RNA依赖性RNA聚合酶PA亚基。本文中，我们报道了从金属结合药效团（MBP）库筛选中鉴定出的先导化合物衍生的流感PA核酸内切酶抑制剂的发展。发现焦果烯酸及其衍生物是核酸内切酶的有效抑制剂。在建模和先前报道的结构数据的指导下，从MBP命中中精心制作了分子的几个子库。建立了结构与活动的关系，使用片段增长和片段合并策略设计和合成了更有效的分子。这种方法最终导致了带有IC的铅化合物的开发50值为14 nM，显示MDCK细胞中针对H1N1流感病毒的EC 50值为2.1μM。

• Basic 3-hydroxypyridin-4-ones: Potential antimalarial agents

  3-Hydroxypyridin-4-ones selectively bind iron under biological conditions and one such compound has found application in the treatment of thalassaemia-linked iron overload. Related molecules have also been demonstrated to possess an antimalarial effect at levels which are non-toxic to mammalian cells. In an attempt to improve the efficiency of such molecules we have investigated the effect of introducing basic nitrogen centres into 3-hydroxypyridin-4-ones in an attempt to achieve targeting to lysosomes and other intracellular acidic vacuoles. Several of the compounds reported in this communication possess enhanced antimalarial activity over that of the simple hydroxypyridinone class. (C) 2007 Elsevier Masson SAS. All rights reserved.

  Epidermal growth factor and vascular endothelial growth factor-2 are important targets of tyrosine kinase for the treatment of various cancerous diseases. Combination of inhibition of both targets to produce synergy in the signal pathway is a critical approach to identify novel tyrosine kinase inhibitors. In this study, a series of new compounds derived from the 4-aminoquinoline as dual inhibitors were synthesized. The obtained results of cytotoxicity assay against human carcinoma cell lines indicated 0.8 mu M for 4c against A549 showing its high efficiency in comparison to erlotinib. Pharmacophore modeling as a structure-based method was investigated on dual inhibitors and 4c which was compared with co-crystallized in the active site of EGFR and VEGFR-2. They have shown the same binding orientation as vandetanib, erlotinib and sorafenib. Molecular dynamics simulation results approved that Met769, Lys721, Asp1046, and Lys868 are key residues in two binding sites for dual activity. Ala1050 and Pro968 were identified as new amino acid interaction sites for dual inhibition. 4c showed more favorable stability than vandetanib in VEGFR-2 receptor for a 50 ns dynamic simulation. The high correlation between essential pharmacophoric features of designed compounds and lead inhibitors interactions provided a deeper insight into the structural basis of 4-aminoquinoline inhibition.
