Biological Activity

Description Lycorine (Galanthidine, Amarylline, Narcissine, Licorine, Belamarine) is a toxic crystalline alkaloid found in various Amaryllidaceae species that weakly inhibits acetylcholinesterase (AChE) and ascorbic acid biosynthesis.
In vitro Lycorine can inhibit protein synthesis in eukaryotic cells and acetylcholinesterase activity. Lycorine could effectively arrest the cell cycle at the G2/M phase and induce apoptosis in HL-60 cells. It is able to block the KM3 cell cycle at G0/G1 phase through the down-regulation of both cyclin D1 and CDK4[2].
In vivo Lycorine, when tested in the human leukemia xenograft models, appears to exhibit anti-tumor activity in vivo. It prolongs the mean survival time of SCID leukemia xenograft models. Lycorine could alleviate the infiltration of tumor cells into tissues[2].

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    Caki-1; ACHN; KPK-1 and Renca cell lines

  • Concentrations

    0, 0.5, 1, 5, and 10 μM

  • Incubation Time

    24, 48, 72, and 96 h

  • Method

    The cell lines Caki-1; ACHN; KPK-1 and Renca are diluted in 96-well plates at a density of 1 × 103 and incubated with medium alone or serial dilutions of lycorine hydrochloride (0, 0.5, 1, 5, and 10 μM). Cell viability is monitored after 24, 48, 72, and 96 h. For each time point, the XTT labeling reagent and an electron coupling reagent is added to the culture. The cells are incubated for 4 h at 37°C and 5% CO2, and absorbance at 450–500 nm, with a reference wavelength at 650 nm, is recorded using a Bio-Rad microplate reader.

Animal Study:[1]
  • Animal Models

    C57BL/6 mice inoculated with Renca-Luc cells into the sub-renal capsule kidney and tail vein (orthotopic tumor and metastatic lung tumors model)

  • Dosages

    5 mg/kg

  • Administration

    i.p.
