  4-Quinazolinones: synthesis and reduction of prostaglandin E2 production

  摘要：

  We synthesized and evaluated the anti-inflammatory activity of a series of 4-quinazolinone derivatives. Two approaches were used to yield the title compounds. A first group of quinazolinone derivatives was obtained by the appropriate substituted anthranilates. A second group of quinazolinone compounds was prepared through the benzoxazin-4-ones intermediate. The pharmacological results reveal that the synthesized derivatives exhibit a significant anti-inflammatory effect in an experimental ocular inflammation model. In fact, all the tested compounds lowered the prostaglandin E-2 (PGE(2)) production with respect to the control group (P < 0.05). The 3-cyclohexyl-6-chloro-quinazolin-4(3H)-one and 3-cyclohexyl-quinazolin-4(3H)-one derivatives were the most active compounds. These compounds significantly reduced PGE(2) levels even more than the reference drug tolmetin and significantly lower protein concentration and polymorphonuclear leukocytes number compared to the control group (P < 0.05). Therefore, these compounds may be useful to prevent ocular inflammatory reactions. (C) 1999 Elsevier Science S.A. All rights reserved.

  Two new families of closely related selective, non‐cytotoxic, and potent antitubercular agents were discovered: thioquinolines and thiazoloquinolines. The compounds were found to possess potent antitubercular properties in vitro, an activity that is dependent on experimental conditions of MIC determination (resazurin test and the presence or absence of Tween‐80). To clarify the therapeutic potential

  bioactive compounds. However, the atropisomerism arising from a restricted rotation around an N–N bond is largely overlooked. Here, we describe a method to access the first enantioselective synthesis of N–N biaryl atropisomers via a Cu-bisoxazoline-catalyzed Friedel–Crafts alkylation reaction. A wide range of axially chiral N–N bisazaheterocycle compounds were efficiently prepared in high yields with

  highly efficient heterogeneous palladium-catalyzed carbonylative annulation of 2-iodoanilines and acid anhydrides has been developed. The reaction proceeds effectively in toluene using N,N-diisopropylethylamine (DiPEA) as the base at 100 °C under 2 bar of CO and provides a novel, general, and practical method for the assembly of a wide variety of 2-alkylbenzoxazinones with high functional group tolerance
