Design and synthesis of new 7,8-dimethoxy-α-naphthoflavones as CYP1A1 inhibitors
摘要:
The flavonoids as inhibitors of CYP1A1 exhibit chemopreventive effects against certain procarcinogens and have been considered as the promising cancer preventive agents. A series of novel 7,8-dimethoxy-alpha-naphthoflavones as the substrate analogs were designed and prepared. The enzyme assay suggested that all of these new flavones were stronger inhibitors of CYP1A1 than the lead compound alpha-naphthoflavone. Among the tested ones, 3h showed the most potent inhibitory effects. (C) 2013 Shao-Shun Li. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.

Syntheses of substituted naphthalenes and naphthols are described. Based on Claisen rearrangement, ring-closing metathesis (RCM), and related reactions, isovanillin was successfully transformed into a series of substituted naphthalenes and naphthols with good overall yields.

AbstractBased on the oxidation of 1,5‐naphthalenediol (4) and 6‐bromo‐2‐naphthol (9) via Teuber reaction, an efficient synthesis of 5,6‐dimethoxy‐1‐naphthol (1) and 5,6‐dimethoxy‐2‐naphthol (2) was achieved with high overall yield (16% for 1 and 25% for 2). The key steps of the synthetic strategy involved the oxidation of naphthols (4 and 9) to the corresponding naphthoquinones (5 and 10) and the conversion of 5,6‐dimethoxy‐2‐naphthaldehyde to 5,6‐dimethoxy‐2‐naphthol formate through Baeyer‐Villiger oxidation‐rearrangement.
