Certain 4,5-diarylisoxazole derivatives have been found to possess broad biological effects, including antiinflammatory and anticancer activities. Recently, we have reported preparation of certain isoflavone derivatives and investigated for their anti-osteoporotic and antiproliferative activities in a detailed SAR study. The present report describes the conversion of isoflavones into novel 4,5-diphenylisoxazole
已经发现某些4,5-二芳基异恶唑衍生物具有广泛的生物学作用,包括抗炎和抗癌活性。最近,我们报道了某些异黄酮衍生物的制备方法,并在详细的SAR研究中对其抗骨质疏松和抗增殖活性进行了研究。本报告描述了通过用NH2OH处理将异黄酮转化为新型4,5-二苯基异恶唑衍生物。烷基化,然后胺化这些4,5-二苯基异恶唑,得到所需的氨基烷氧基取代的4,5-二苯基异恶唑衍生物。在体外评估这些化合物的成骨分化和矿化定量。尽管5-异丙氧基-2- [4-(4-(4-甲氧基苯基)异恶唑-5-基]苯酚(3)表现出大约2。在促进成骨细胞活性(277%矿化),比细胞活力低(6%)和高细胞毒性(68%)方面,活性比伊普黄酮高8倍,这促使我们进一步寻求更合适的候选药物。引入了一系列氨基烷基侧链,目的是减少细胞毒性。其中,5- 4-异丙氧基-2- [4-(吡咯烷-1-基)丁氧基]苯基} -4-(4-甲氧基苯基)异唑(7a)的活性
