我们使用基于结构的设计策略确定了p38 MAP激酶的新型有效抑制剂。X射线晶体学表明,当p38MAP激酶与络合TAK-715(1在共晶体结构),Phe169采用两种构象,其中,一个与相互作用1,而另一个示出了具有没有相互作用1。我们基于结构的设计策略表明,这两个构象通过增强的蛋白质-配体疏水相互作用融合为一个构象。根据该策略,我们专注于支架转化以鉴定咪唑并[1,2- b ]哒嗪衍生物作为p38 MAP激酶的有效抑制剂。在本文所述和评估的化合物中,N-氧化物16在人单核细胞THP-1细胞中显示出对p38 MAP激酶和LPS诱导的TNF-α产生的有效抑制作用,并且在大鼠胶原诱导的关节炎模型中具有显着的体内功效。在本文中,我们报告发现具有吡啶N-氧化物基团的有效,选择性和口服可生物利用的咪唑并[1,2 - b ]哒嗪基p38 MAP激酶抑制剂的发现。

trifluoromethyl ketones starting from readily accessible aryl bromides and fluorosulfates, the latter easily prepared from the corresponding phenols. The methodology utilizes low pressure carbon monoxide generated ex situ from COgen to generate Weinreb amides as reactive intermediates that undergo monotrifluoromethylation affording the corresponding aromatic trifluoromethyl ketones (TFMKs) in good

The invention relates to tetra-substituted heteroarylic compounds of the formula (I) wherein X1, X3 and X4 are independently C or N, Y is C-H, N-H or N, wherein the total number of nitrogen atoms represented by X1, X3, X4 and Y is 1 or 2; rings A and B are independently selected from phenyl or pyridyl; R1, R4, R', R", n and m are as defined herein. Such compounds are suitable for the treatment of a disorder or disease which is mediated by the activity of MDM2 and/or MDM4, or variants thereof.

agriculture, but the presence of a steroid skeleton hampers the field application of BL in agriculture because of its high synthetic cost. We discovered NSBR1 as the first nonsteroidal BL-like compound using in silico technology. Searching for more potent BL-like compounds, we modified the structure of NSBR1 with respect to 2 benzene rings and the piperazine ring. The activity of synthesized compounds
