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

research in our lab found that natural phenanthrenes derived from Traditional Chinese Medicine Baiyangjie could inhibit liver fibrosis through inhibiting TGF-β1, TNF-α and promoting the secretion of MMP-9. Herein, in order to optimize the structure of phenanthrenes to maximize their anti-fibrosis activities, a series of phenanthrene derivatives were designed and synthesized in an expeditious manner. Their
