  Synthesis and activity of a new series of chalcones as aldose reductase inhibitors

  摘要：

  A new series of chalcone derivatives has been synthesized and tested in vitro in order to assess their ability to inhibit aldose reductase enzyme (ALR2) and their specificity towards the target enzyme with respect to other oxidoreductases, such as aldehyde reductase, sorbitol dehydrogenase, and glutathione reductase. All the compounds display affinity for ALR2. The X-ray crystal structure of 1-(2,4-dihydroxyphenyl)-3-(2-methoxyphenyl)propen-1-one was determined. (C) Elsevier, Paris.

Although possessing certain limitations, the most generally suitable methods involve the condensation of a suitably substituted acetophenone and the appropriate benzaldehyde by means of alkali. Most of the compounds describejd here were prepared by this general procedure. The use of Russell’s2 method was found necessary in a few cases.

  synthesized isoliquiritigenin analogs with electron-donating and electron-withdrawing functional groups. These analogs were evaluated for neuroprotective effect against glutamate-induced neurotoxicity in HT22 cells. Among these analogs, compound BS11 was selected as a potent neuroprotective agent. Cellular Ca2+ concentration, ROS level, MAPKs activation and AIF translocation to the nucleus were increased upon

  Two series of compounds (chalcones and bis-chalcones) were designed, synthesized, and evaluated as aglucosidase inhibitors (AGIs) with 1-deoxynojirimycin as positive control in vitro. Most of the compounds with two or four hydroxyl groups showed better inhibitory activities than 1-deoxynojirimycin towards aglucosidase with noncompetitive mechanism. Moreover, most of the hydroxy bis-chalcones exhibit good a-glucosidase inhibitory activities in enzyme test. Inspiringly, bis-chalcones 2g (at 1 mu M concentration) has stronger effect than 1-deoxynojirimycin on reducing the glucose level in HepG-2 cells (human liver cancer cell line).
