  New imidazo[1,2-a]pyridines carrying active pharmacophores: Synthesis and anticonvulsant studies

  摘要：

  Five new series of imidazo[1,2-a]pyridines carrying biologically active pyrazoline (4a-e), cyanopyridone (5a, b), cyanopyridine (6a-f), 2-aminopyrimidine (7a-f) and pyrimidine-2-thione (8a-d) systems were designed and synthesized as prominent anticonvulsant agents. The target compounds were screened for their in vivo anticonvulsant activity following maximal electroshock (MES) and subcutaneous pentylene tetrazole (scPTZ) methods at a small test dose of 10 mg/kg. Further, Rotarod toxicity method was used to study the toxicity profile of selected compounds. Compounds 4b, 5a, 5b, 6a, 7e and 8d possessing 4-fluorophenyl substituent at 2nd position of imidazo[1,2-a]pyridine ring displayed potent anticonvulsant activity without displaying any toxicity. Enhanced activity profile was observed for new compounds in PTZ method over MES method. (c) 2012 Elsevier Ltd. All rights reserved.

  摘要：

  目的合成并评价稠合杂环咪唑并[1,2-a]吡啶肟作为对氧磷抑制乙酰胆碱酯酶的再激活剂。背景技术有机磷化合物(OP)包括对硫磷、马拉硫磷、毒死蜱、久效磷和二嗪农，它们通常用于农业中，通过杀死破坏作物的害虫来提高农业生产力。然而，人们可能会通过摄入、吸入或皮肤无意/有意地接触到 OPs 杀虫剂。目前的治疗方案包括再激活剂，例如单或双吡啶肟，以及推荐用于治疗 OP 中毒的抗胆碱能药物和抗惊厥药物。不幸的是，现有再活化剂的缺点是吡啶鎓上存在永久电荷，使它们无法通过血脑屏障 (BBB) 并重新激活 OP 抑制的中枢神经系统 (CNS) 乙酰胆碱酯酶。因此，需要一种可以穿过 BBB 并重新激活 OP 抑制的乙酰胆碱酯酶的再激活剂。目的该研究的目的是合成、分子对接、BSA 结合和体外评价各种取代的咪唑并[1,2-a] 吡啶的肟对对氧磷抑制乙酰胆碱酯酶的作用。方法 再活化剂分三步合成，并使用各种光谱技术进行表征。使用

  Abstract Herein, we report design, one pot synthesis and antibacterial evaluation of novel imidazopyridine bearing pyran bis-heterocycles. The compounds were synthesized in an aqueous solution of gluconic acid under both conventional heating and ultrasound irradiation. The target compounds were obtained in good to moderate yields with yield of 65–88% in 20–60 min under ultrasonic irradiation. The compounds

  摘要在此，我们报告了新型含吡喃双杂环的咪唑并吡啶的设计、一锅合成和抗菌评价。这些化合物是在葡萄糖酸水溶液中在常规加热和超声照射下合成的。目标化合物在超声波照射下以良好到中等的收率在 20-60 分钟内获得 65-88% 的收率。化合物通过光谱方法 IR、1H NMR、13C NMR、MS 和 HRMS 进行表征。还测定了 7i 的 X 射线单晶结构。通过使用圆盘扩散法测量抑菌圈来评估化合物的抗菌活性，该法显示一些化合物抑制革兰氏阳性菌和革兰氏菌属细菌的生长。最低抑菌浓度（MIC）结果表明，7a、7h 和 7a-7k 系列中的 7k 抑制了金黄色葡萄球菌的生长。确定 7a、7h 和 7k 的最小杀菌浓度 (MBC) 值。衍生物 7a、7k、7h 的 MBC/MIC 比率表明前两种衍生物充当杀菌剂，后来充当对抗革兰氏阳性菌的抑菌剂。溶血结果表明化合物对红细胞无细胞毒性。

  The present article reports the synthesis and anticonvulsant studies of new 2-arylimidazo[1,2-a]pyridines carrying suitably substituted 1,2,3-triazoles as well as their intermediates. The structures of newly synthesized compounds were confirmed by various spectroscopic techniques. The anticonvulsant study was carried out by MES and scPTZ screening methods, while their toxicity study was performed following Rotarod method. The active compounds showed enhanced seizure control in scPTZ method when compared with that of MES method. Compounds 3f, 4c, 4f, 5k, 5p and 5w carrying active pharmacophores exhibited complete protection against seizure and their results were comparable with standard drug diazepam. Majority of new compounds were found to be non-toxic, while few of them showed toxicity at 100 mg/kg. The c log P values of target compounds are in the range of 3.5-5.3, which confirm their lipophilic nature. (C) 2013 Elsevier Ltd. All rights reserved.
