(+)-Isocorynoline

Isocorydine is isolated from Dicranostigma leptopodum (Maxim.) Fedde (DLF). Isocorydine combines with Doxorubicin (DOX) has a promising potential to eradicate hepatocellular carcinoma (HCC)[1].

Isocorydine (0-400 ug/ml; 48 hours) show a significant decrease in the IC50 for ICD and DOX, the CI values are 0.605, 0.644, 0.804, and 0.707 respectively for Huh-7, Hep-G2, SNU-449 and SNU-387[1]. Isocorydine (0-400 ug/ml; 48 hours) abrogates DOX-induced upregulation of mesenchymal markers and the downregulation of epithelial markers in human HCC cell lines[1]. Cell Viability Assay[1] Cell Line: Huh-7, Hep-G2 , SNU-387, SNU-449 cells Concentration: 0-400 ug/ml Incubation Time: 24 hours Result: Had a higher cytotoxicity in HCC cells in comparison to ICD or DOX alone. Western Blot Analysis[1] Cell Line: Huh-7, Hep-G2 , SNU-387, SNU-449 cells Concentration: Incubation Time: 24 hours Result: Downregulated protein levels of Claundin-1 and E-cadherin.

Isocorydine (intraperitoneal injection; 0.4 mg/kg; every 2 days for 2 weeks) retards the tumor growth, but the combined treatment of Doxorubicin (DOX) or ICD significantly inhibits tumor growth[1]. Animal Model: Female nude mice[1] Dosage: 0.4 mg/ml Administration: Injected intraperitoneally every 2 days for 2 weeks Result: Combined treatment of isocorydine and DOX showed a promising potential to eradicate HCC.
