  Benzylidenemalononitrile compounds as activators of cell resistance to oxidative stress and modulators of multiple signaling pathways. A structure–activity relationship study

  摘要：

  Benzylidenemalononitrile (BMN) tyrphostins are well known as potent tyrosine kinase inhibitors. Moreover, in recent years it has been recognized that members of the tyrphostin family possess additional biological activities independent of their ability to inhibit protein tyrosine kinases. In this study, we examined the relationship between the structure of 49 BMNs and related compounds, and their capacity to induce heme oxygenase 1 (HO-1) gene expression in U937 human monocytic cells, to activate upstream signaling pathways and to protect cells against menadione-induced oxidative stress. It was found that the electron-withdrawing (NO2, CN, halogen) groups in BMN molecules and double meta-MeO substituents increased the HO-1 gene induction, while the electron-donating groups in ortho/para position (OH, MeO and N-morpholino) significantly decreased it. The magnitude of activation of c-Jun, Nrf2, p38 MAPK, and p70S6K correlated with specific substitution patterns in the BMN structure. BMN-dependent maximal up-regulation of HO-1 required parallel increase in Nrf2 and phospho-c-Jun cellular levels. Liquid chromatography mass spectrometry (LC-MS) analysis revealed that BMNs can generate conjugates with one or two glutathione equivalent(s). This study supports the hypothesis that BMNs induce the expression of protective genes by alkylating sensitive cysteine residues of regulatory factors. (C) 2011 Elsevier Inc. All rights reserved.

  摘要：

  抑制α-葡萄糖苷酶对于治疗糖尿病（DM）至关重要。除许多有机支架外，以前已报道吡啶基化合物具有广泛的生物活性。本研究报告了一系列基于吡啶的合成类似物，通过体外，动力学和计算机模拟研究评估了其对α-葡萄糖苷酶抑制的潜力。为此目的，合成了2-氨基-4-芳基-6-（苯硫基）吡啶-3，5-二腈1-28，并进行了体外筛选。与标准阿卡波糖（IC50 = 750±10 µM）相比，包括1-3、7、9、11-14和16在内的几种类似物显示出许多潜在的抑制作用增加。有趣的是，化合物7（IC50 = 55.6±0.3 µM）的抑制强度是标准阿卡波糖的13倍。对最有效分子7的动力学研究揭示了竞争型抑制机制。在计算机上进行了研究以检查配体（化合物7）与α-葡糖苷酶的活性位点残基的结合模式。

  beta-Lactams are used routinely to treat Staphylococcus aureus infections. However, the emergence of methicillin-resistant S. aureus (MRSA) renders them clinically precarious. We describe a class of cinnamonitrile adjuvants that restore the activity of oxacillin (a penicillin member of the beta-lactams) against MRSA. The lead adjuvants were tested against six important strains of MRSA, one vancomycin-intermediate S. aureus (VISA) strain, and one linezolid-resistant S. aureus strain. Five compounds out of 84 total compounds showed broad potentiation. At 8 mu M (E)-3-(5-(3,4-dichlorobenzy1)-2-(trifluoromethoxy)phenyl)-2-(methylsulfonyl)acrylonitrile (26) potentiated oxacillin with a >4000-fold reduction of its MIC (from 256 to 0.06 mg.L-1). This class of adjuvants holds promise for reversal of the resistance phenotype of MRSA.
