    摘要:
    FMS样酪氨酸受体激酶3(FLT3)的异常激活与20-30%的患者的急性髓细胞性白血病(AML)的发病机制有关。在这项研究中,我们确定了高选择性(苯基乙烯基)喹唑啉化合物家族作为FLT3-ITD和FLT3-D835Y激酶的新型有效抑制剂。通过生化和细胞增殖测定以及随后的小鼠异种移植研究,证实了它们的显着效果。我们的建模实验和化合物的化学结构预测了共价抑制的可能性。最有效的化合物触发了FLT3-ITD AML细胞的凋亡,但在不依赖FLT3的白血病和非白血病细胞系中作用微弱或没有作用。

    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.

  • Visible light induced tandem reactions: An efficient one pot strategy for constructing quinazolinones using in-situ formed aldehydes under photocatalyst-free and room-temperature conditions

    aminobenzamides and in-situ generated aldehydes. Visible light was found to play a dual role: first oxidizes the alcohol to the aldehyde and then facilitates its cyclization with o-substituted aniline. Furthermore, alcohols are perfect alternatives to aldehydes because they are greener, more available, more economical, more stable, and less toxic than aldehydes. The first reaction step continuously
    已经开发了一种从各种氨基苯甲酰胺和原位生成的醛构建喹唑啉酮的简便串联途径。发现可见光起着双重作用:首先将醇氧化成醛,然后促进其与邻苯二甲酸的环化。取代的苯胺。此外,醇是醛的完美替代品,因为它们比醛更绿色,更易得,更经济,更稳定且毒性更低。第一反应步骤连续地为第二步骤提供材料,该材料有效地减少了由于醛的挥发,氧化和聚合而造成的损失,同时避免了其毒性。可以在可见光存在下制备各种喹唑啉酮,而无需任何其他光催化剂。发达的合成方案具有温和条件,广泛的底物范围,操作简便和高原子效率的优点,并在无金属,无光催化剂和环境条件下具有生态能源。
