Synthesis and biological evaluation of 1-[2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl]-4-ethynylimidazole. A novel and highly potent anti-inflammatory and cytoprotective agent
摘要:
To explore more potent N-acylimidazole analogues of CDDO than CDDO-Im, which is one of the most potent compounds in several widely used bioassays related to protection against inflammation and carcinogenesis; we have synthesized and evaluated five new N-acyl(acetylenic) imidazole analogues. Among them, 4-ethynylimidazole 4 is nearly equivalent to CDDO-Im in potency in these bioassays. Remarkably, the solid form of 4 is more stable than that of CDDO-Im. These findings suggest that 4 is a very promising anti-inflammatory and cytoprotective agent and its further preclinical evaluation is warranted. (C) 2011 Elsevier Ltd. All rights reserved.
摘要我们描述了配体4-[((2-咪唑基乙炔基)]-5-(2-吡啶基乙炔基)杂芳基及其与银(I)和钯(II)的配位配合物的设计,合成和表征。1 H NMR滴定清楚地表明两种阳离子均形成1:1配位络合物。二氯化钯配合物的X射线结构证实了钯(II)的反式配位,三氟甲磺酸银配合物证实了关于银(I)的线性配位的几何形状。下载:下载高分辨率图像(74KB)下载:下载完整尺寸的图像
