  Synthetic analogs of daidzein, having more potent osteoblast stimulating effect

  摘要：

  A series of didzein derivatives were synthesized and assessed for stimulation of osteoblast differentiation using primary cultures of rat calvarial osteoblasts. Data suggested that three synthetic analogs, 1c, 3a and 3c were several folds more potent than daidzein in stimulating differentiation and mineralization of osteoblasts. Further, these three compounds did not show any estrogen agonistic activity, however had mild estrogen antagonistic effect. Out of the three compounds, 3c was found to maximally increase the mineralization of bone marrow osteoprogenitor cells. Compound 3c also robustly increased the mRNA levels of osteogenic genes including bone morphogenetic protein-2 and osteocalcin in osteoblasts. Unlike daidzein, 3c did not inhibit osteoclastogenesis. Collectively, we demonstrate osteogenic activity of daidzein analogs at significantly lower concentrations than daidzein. (C) 2010 Elsevier Ltd. All rights reserved.

  Recently we have shown that daidzin, the major active principle of an ancient herbal treatment for "alcohol addiction", suppresses ethanol intake in alcohol-preferring laboratory animals. Further, we have identified the monoamine oxidase (MAO)-aldehyde dehydrogenase (ALDH-2) pathway of the mitochondria as the potential site of action of daidzin. Daidzin analogues that potently inhibit ALDH-2 but have no or little effect on MAO are most antidipsotropic, whereas those that also inhibit MAO exhibit little, if any, antidipsotropic activity. Therefore, in the design and synthesis of more potent antidipsotropic analogues, structural features important for the inhibition of both ALDH-2 and MAO must be taken into consideration. To gain further information on the structure-activity relationships at the inhibitor binding sites of ALDH-2 and MAO, we prepared 44 analogues of daidzin and determined their potencies for ALDH-2 and MAO inhibition. Results indicate that a sufficient set of criteria for a potent antidipsotropic analogue is an isoflavone with a free 4 ' -OH function and a straight-chain alkyl substituent at the 7 position that has a terminal polar function such as -OH, -COOH, or -NH2. The preferable chain lengths for the 7-O-omega -hydroxy, 7-O-omega -carboxy, and 7-O-omega -amino subsitutents are 2 less than or equal to n less than or equal to 6, 5 less than or equal to 5 n less than or equal to 10, and n greater than or equal to 4, respectively. Analogues that meet these criteria have increased potency for ALDH-2 inhibition and/or decreased potency for MAO inhibition and therefore are likely to be potent antidipsotropic agents.
