    vs rat A1 or A2A receptors. The 2-styryl-6-propoxy derivative, 20, of the furanochromone visnagin was 30-fold selective for human A3 receptors vs either rat A1 or A2A receptors. Several of the more potent derivatives effectively antagonized the effects of an agonist in a functional A3 receptor assay, i.e. inhibition of adenylyl cyclase in CHO cells expressing cloned rat A3 receptors. In conclusion,

    3-methoxyphenol (1) and 3,5-dimethoxyphenol (2), respectively, with methoxyacetyl chloride in the presence of aluminum chloride in 1,1,2,2-tetrachloroethane (Scheme 1). The electrophilic aromatic substitution by 2-methoxyacetylium cation occurred exclusively in the 6-position of 1 and the 2-position of 2 and afforded 3 and 4 with 82% and 73% yields, respectively, after acidic workup and chromatographic separation

    inhibitors. The inhibition of luteolin was noncompetitive with respect to the substrate in the NADPH-dependent reduction direction, but CBR1 exhibited moderate NADP(+)-dependent dehydrogenase activity for some alicyclic alcohols, in which the luteolin inhibition was competitive with respect to the alcohol substrate (Ki59nM). The SAR of the flavonoids indicated that the 7-hydroxy group of luteolin was responsible
    人羰基还原酶1(CBR1)是短链脱氢酶/还原酶超家族的成员,可还原包括治疗药物在内的多种羰基化合物。CBR1参与将蒽环类抗癌药还原为抗心脏癌性较低的C-13羟基代谢物。人们认为CBR1抑制剂是辅助治疗的有前途的药物,在延长蒽环类药物的抗癌功效同时降低心脏毒性(药物的副作用)方面具有双重有益作用。在这项研究中,我们评估了27种黄酮类化合物对CBR1的抑制活性,以探讨其结构-活性关系(SAR)。其中,木犀草素(2-(3,4-二羟基苯基)-5,7-二羟基-4H-1-苯并吡喃-4-酮)表现出最强的抑制作用(IC5095nM),与所有已知类别的CBR1抑制剂相比,它的功效更强。木犀草素的抑制作用相对于底​​物在NADPH依赖性还原方向上是非竞争性的,但是CBR1对某些脂环族醇表现出中等的NADP(+)依赖性脱氢酶活性,其中木犀草素的抑制作用相对于醇底物具有竞争性( Ki59nM)。黄酮类化合物的SA
