  Regioselectivity of the Diels-Alder reactions of 2,5,8(1H)-quinolinetriones

  摘要：

  Diels-Alder reactions of 2,5,8(1H)-quinolinetriones were completely regioselective for all the unsymmetrical dienes tested, except in the case of isoprene. This corresponds to a level of regioselectivity higher than the one found by previous workers for 5,8-quinolinequinone.

  6-(3-Indolyl)quinolinequinone derivatives gave regioselective Diels–Alder reactions with a variety of dienophiles, yielding polycyclic carbazole derivatives. One-pot reactions, proceeding through a cascade of reactions including regioselective Michael and Diels–Alder steps, gave heptacyclic derivatives starting from indoles and 2,5,8(1H)-quinolinetriones.

  that is different from the initially expected Bartoli indole synthesis. Thus, instead of giving fused indole derivatives, these reactions provide a very mild and efficient new procedure for the synthesis of synthetically relevant aromatic systems containing an o‐nitrovinyl moiety, such as 5‐nitro‐4‐vinylindoles, 6‐nitro‐7‐vinylindoles, 6‐nitro‐5‐vinyl‐2(1H)quinolinones, and 4‐nitro‐3‐vinylanilines.

Sulfur-containing quinolinequinones (21, 24) were prepared by oxidation of the corresponding 5, 8-dimethoxy- or 5, 6, 8-trimethoxy-2(1H)-quinolinethiones (20, 23).

• Discovery of quinone-directed antitumor agents selectively bioactivated by NQO1 over CPR with improved safety profile

  In this work, we mainly focused on discovering compounds with good selectivity for NQO1 over CPR. The NQO1-mediated two-electron reduction of compounds would kill cancer cells selectively, while CPR-mediated one-electron reduction would induce potential hepatotoxicity. Several novel quinone-directed antitumor agents were discovered as specific NQO1 substrates through structure-activity relationship studies. Among them, compound 3,7,8-trimethylnaphtho[1,2-b] furan-4,5-dione (12b) emerged as the most specific substrate of the two-electron oxidoreductase NQO1 and could hardly be reduced by CPR. It afforded the highest selectivity between NQO1/CPR (selectivity ratio = 6.37), much higher than the control beta-lapachone (selectivity ratio = 1.36), indicated 12b may possess superior safety profile. The electrochemical studies provided a reasonable explanation to the good selectivity toward NQO1. Molecular docking studies supported that 12b was capable of forming additional C-H... pi interactions with Trp105 and Phe178 residues compared to the control beta-lap. In addition, compound 12b was shown to kill cancer cells efficiently both in vitro and in vivo model. This work gave us a promising and novel scaffold for further investigation.

• Synthesis of Casimiroin and Optimization of Its Quinone Reductase 2 and Aromatase Inhibitory Activities

  An efficient method has been developed to synthesize casimiroin (1), a component of the edible fruit of Casimiroa edulis, on a multigram scale in good overall yield. The route was versatile enough to provide an array of compound 1 analogues that were evaluated as QR2 and aromatase inhibitors. In addition, X-ray crystallography studies of QR2 in complex with compound 1 and one of its more potent analogues has provided insight into the mechanism of action of this new series of QR2 inhibitors. The initial biological investigations suggest that compound 1 and its analogues merit further investigation as potential chemopreventive or chemotherapeutic agents.
