  Synthesis and evaluation of new coumarin–pyridine hybrids with promising anti-osteoporotic activities

  摘要：

  Anti-osteoporotic effects of the newly synthesized coumarin pyridine hybrids were evaluated in primary cultures of rat calvarial osteoblasts in vitro. Compounds 6a, i, j and k were potent in stimulating osteoblast differentiation and mineralization as assessed by the alkaline phosphatase production and alizarin red-S staining assay, respectively. These compounds were also found to be nontoxic in osteoblast cells as compared to the control group in an MTT assay. Furthermore, the effect of these compounds on the transcript levels of osteogenic genes revealed that the compound 6j robustly enhanced mineralization of the osteogenic genes in calvarial osteoblasts. In this context, compound 6j was selected as a potential lead for further structural optimization in the development of new anti-osteoporotic agents. (C) 2013 Elsevier Masson SAS.

  First synthesis of novel coumarin–trioxane hybrids is reported. The synthesis was achieved via condensation of β-hydroxyhydroperoxides with coumarinic-aldehydes in presence of p-toluenesulfonic acid in good yields and the novel hybrids were evaluated for their antimalarial activity both in vitro and in vivo.

  A series of coumarin-chalcone hybrids have been synthesized and evaluated for their in vitro cytotoxicity against a panel of four human cancer cell lines and normal fibroblasts (NIH3T3). Among 21 compounds screened, three compounds (23, 25 and 26) showed IC50 range from 3.59 to 8.12 mu M. The most promising compound 26 showed around 30-fold more selectivity towards C33A (cervical carcinoma) cells over normal fibroblast NIH3T3 cells with an IC50 value of 3.59 mu M.

  The concept of molecular hybridization led us to discover a novel series of coumarin- dihydropyridine hybrids that have potent osteoblastic bone formation in vitro and that prevent ovariectomy-induced bone loss in vivo. In this context, among all the compounds screened for alkaline phosphatase activity, four compounds 10, 14, 18, and 22 showed significant activity at picomolar concentrations. A series of other in vitro data strongly suggested compound 18 as the most promising bone anabolic agent, which was further evaluated for in vivo studies. From these studies compound 18 proved to be useful, which at low oral dose of 1 (mg/kg)/day body weight increased bone mass density and volume, expression of osteogenic genes (RUNX2, BMP-2, and Coll), bone formation rate (BFR), and mineral apposition rate (MAR), improved the trabecular microarchitecture, and decreased bone turn over markers in an ovariectomized rodent model for postmenopausal osteoporosis.

  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
