dibenzoquinoline 33b, showed improved solubility compared to tylophorine 9a, in vivo efficacies in a lung A549 xenografted tumor mouse model and a murine paw edema model, good bioavailability, and no significant neurotoxicity (as tested by a rota-rod test for motor coordination). This is the first study to explore in detail the role of the tylophorine E ring on biological activity and very strongly suggests
合成了一系列新颖的酪氨酸衍生的二苯并喹啉,并对其生物学活性进行了评估。进行了三种测定:抑制癌细胞增殖,抑制针对抗冠状病毒活性的TGEV复制以及抑制RAW264.7细胞中一氧化氮的产生(一种抗炎措施)。这些测定中最有效的化合物二苯并喹啉33b与酪氨酸9a相比显示出更高的溶解度,在肺A549异种移植肿瘤小鼠模型和鼠爪水肿模型中的体内功效,良好的生物利用度,并且没有明显的神经毒性(通过运动协调性旋转棒检验)。这是首次详细研究酪氨酸E环对生物活性的作用的研究,并且非常有力地表明,酪氨酸衍生的二苯并喹啉应进一步发展为口服活性剂。
