Out of three promising compounds, 6l and 6o significantly induced apoptosis in MDA-MB-231 cancer cells via mitochondrial depolarisation without affecting normal cells. In an in vitro co-culture model of bone metastasis, we investigated the ability of coumarin–imidazo[1,2-a]pyridine hybrids to reverse the negative impact of MDA-MB-231 cancer cells on osteoblast differentiation. The results illustrate
利用银(I)催化的Groebke-Blackburn-Bienayme多组分反应合成了一系列具有重要生物学意义的6-(咪唑并[1,2 - a ]吡啶-2-基)-2 H -chromen-2-one衍生物。通过碱性磷酸酶测定法和茜素红-S染色测定法在原发性颅盖骨成骨细胞中测试了合成的化合物的可能的骨保护特性。此外,通过qPCR测量活性化合物6h,6l和6o对成骨基因BMP2,RUNX2,COL1和OCN表达的影响。在三种有前途的化合物中,每升6升6a和6o通过线粒体去极化显着诱导了MDA-MB-231癌细胞的凋亡,而不影响正常细胞。在体外骨转移共培养模型中,我们研究了香豆素-咪唑并[1,2- a ]吡啶杂化物逆转MDA-MB-231癌细胞对成骨细胞分化的负面影响的能力。结果说明了设计的杂交体重建骨骼稳态的潜力。这些发现证明了新合成的杂种作为先导分子的重要性,既具有抗骨质疏松性又具有抗癌性,可
