viability/proliferation and COX-2 levels were evaluated. Moreover, using in vivo methods, the compounds were tested for antinociceptive activity in models of acute pain (the writhing and the hot-plate tests) in mice. Their influence on the motor coordination effect and locomotor activity was also tested. The obtained results revealed that the compounds F1–F4 strongly suppress the pain of peripheral origin and
本研究旨在设计和合成一系列 2-羟基-3-(4-aryl-1-哌嗪基)丙基邻苯二甲酰亚胺衍生物,它们是 1 H-吡咯并[3,4-c]吡啶-1,3的类似物。 (2 H )-二酮衍生物,具有经证实的镇痛作用。根据Lipinski 规则提出的基本原则,评估了F1 - F4邻苯二甲酰亚胺的可能生物利用度。所得值表明口服给药后吸收良好,并且能够穿过血脑屏障。四种化合物F1 – F4在酰亚胺氮原子上的 2-羟基-3-(4-芳基-1-哌嗪基)丙基的苯基中的药效团类型不同 (R, F1 –F3 ) 和 4-二苯甲基类似物 ( F4 ) 被选择用于体外和体内研究。基于体外研究,评估了化合物F1 – F4对细胞活力/增殖和 COX-2 水平的影响。此外,使用体内方法,在小鼠急性疼痛模型(扭体和热板测试)中测试了这些化合物的镇痛活性。还测试了它们对运动协调效果和运动活动的影响。获得的结果表明,化合物F1 - F
Design, Synthesis and Antimalarial Activity of Some New Aminoalcoholpyrrolo[1,2-a]quinoxaline Derivatives
Following our search for antimalarial compounds, novel series of piperazinylalcohol pyrrolo[ 1,2-a]quinoxalinederivatives 1-2 were synthesized from 2-nitroaniline or 2-amino-3- nitrophenol and tested for in vitro activity upon the intraerythrocytic stage of W2 and 3D7 Plasmodium falciparum strains. Biological results showed good antimalarial activity with IC50 ranging from 0.3 to 21.1 µM. In attempting
