combustion synthesis-bismuth oxide (Bi2O3) as catalyst for the simple and efficient synthesis of 1,2-oxazine based derivatives of 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazoles, 1-arylpiperazine and carbazoles. (4aR,8aR)-4-(4-Methoxyphenyl)-3-((4-(4-methoxyphenyl)piperazin-1-yl)methyl)-4a,5,6,7,8,8a-hexahydro-4H-benzo[e][1,2]oxazine was found to be the most potent compound with a high degree of selectivity in
在本研究中,我们使用固溶燃烧合成-氧化铋(Bi 2 O 3)作为催化剂,可以简单有效地合成基于1,2-恶嗪的6-氟-3-(哌啶丁-4-基)苯并衍生物。 [ d ]异恶唑,1-芳基哌嗪和咔唑。(4a R,8a R)-4-(4-甲氧基苯基)-3-(((4-(4-甲氧基苯基)哌嗪-1-基)甲基)-4a,5,6,7,8,8a-六氢- 4 H-苯并[ e发现[] [1,2]恶嗪是最有效的化合物,对COX2(1.7μM)的抑制作用比对COX1(40.4μM)的抑制作用高,证明了1,2-恶嗪衍生物在开发COX2特异性抑制剂中的重要性。分子对接分析表明,COX1活性位点中的异亮氨酸残基负责降低与COX1的亲和力并提高对COX2的效力。总体而言,我们的研究表明,新的基于1,2-恶嗪的小分子在开发用于抗炎治疗的COX2特异性抑制剂中符合铅结构的条件。
