in vitro cytotoxicity activity of thiazolidin-4-ones against Vero cells was also performed and four compounds (4a, 4c, 4d and 4f) showed no toxic effect at 500 μg/mL. A docking simulation of compounds into the 1Q4G (COX-1) and 4PH9 (COX-2) enzymes binding site was conducted. This preliminary result will guide us in for further studies to improve the anti-inflammatory activity.
通过4-(2-氨基乙基)吗啉(2-吗啉代乙胺),戊二醛和巯基乙酸回流甲苯一锅反应19小时,可轻松合成七个带有吗啉代基团的新的4-噻唑烷酮(45–97 %)。这些新型化合物已通过NMR光谱法和质谱法得到了全面鉴定和表征。使用巴豆油诱导的BALB C小鼠炎症耳水肿模型确定噻唑烷定-4-酮的体内抗炎活性。对于化合物4c(49.20 mmol / kg),4d(49.20 mmol / kg)和4f发现最佳结果(52.48 mmol / kg),与标准药物消炎痛相比,该药具有分别使小鼠耳部水肿减少50%,48%和54%的能力。此外,噻唑烷-4-酮对Vero细胞的体外细胞毒性活性也得到了证实,四种化合物(4a,4c,4d和4f)在500μg/ mL下均无毒性作用。进行了化合物到1Q4G(COX-1)和4PH9(COX-2)酶结合位点的对接模拟。该初步结果将指导我们进行进一步的研究以提高抗炎活性。
