In the present study, a series of 3,4-dihydro-2(1H)-quinolinone derivatives were synthesized and evaluated as inhibitors of recombinant human monoamine oxidase (MAO) A and B. The 3,4-dihydro-2(1H)-quinolinone derivatives are structurally related to a series of coumarin (1-benzopyran-2-one) derivatives which have been reported to act as MAO-B inhibitors. The results document that the quinolinones are
potent inhibitory activity (MIC=2 μg/mL) against Pseudomonas aeruginosa 2742, indicating that its antibacterial spectrum is similar to those of the positive controls gatifloxacin and moxifloxacin. Structure‐activity relationships (SAR) analyses and dockingstudies implicated the dihydrotriazine group in increasing the antimicrobial potency of the quinoline compounds. In vitro enzyme study implied that compound

5‐dihydro[1,2,4]triazolo[4,3‐a]quinolin‐1‐amine) and 5i (7‐(p‐chlorobenzyloxy)‐4,5‐dihydro[1,2,4]triazolo[4,3‐a]quinolin‐1‐amine) showed the highest anti‐inflammatory activity (52% and 58% inhibition, respectively, at 2 h pre‐administration) which were comparable to or even slightly more potent than the reference drug ibuprofen (55%). Furthermore, the structure‐activity relationship of these 1,2,4‐triazole

A new series of 8-alkoxy-5,6-dihydro-[1,2,4]triazino[4,3-a]quinolin-1-one derivatives were synthesized. Their anticonvulsantactivities were evaluated by the maximal electroshock (MES) test, and their neurotoxicities were evaluated by the rotarod neurotoxicity test. The results showed that 8-heptyloxy-5,6-dihydro-[1,2,4]triazino[4,3-a]quinolin-1-one 5t was the most potent with median effective dose
合成了一系列新的8-烷氧基-5,6-二氢-[1,2,4]三嗪[4,3 - a ]喹啉-1-酮衍生物。通过最大电击(MES)测试评估其抗惊厥活性,并通过旋转脚架神经毒性测试评估其神经毒性。结果显示8-庚氧基-5,6-二氢-[1,2,4]三嗪[4,3 - a ]喹啉-1-酮5t最有效,中位有效剂量(ED 50)值为11.4。 mg / kg,中毒剂量(TD 50)为114.1 mg / kg,提供保护指数(PI = TD 50 / ED 50)值10.0,远大于原型药物卡马西平的PI(PI = 6.4)。为了解释抗惊厥活性的可能机制,在化学诱导的癫痫发作中对化合物5t进行了测试。
