Glaucocalyxin B is an ent kaurane diterpenoid isolated from the Chinese traditional medicine Rabdosia japonica with anticancer and antitumor activity; decreases the growth of HL-60 cells with an IC50 of approximately 5.86 μM at 24 h.
Glaucocalyxin A (GlnA) and (GlnB) dose-dependently decrease the growth of HL-60 cells with an IC50 of approximately 6.15 and 5.86 µM at 24 h, respectively. Both Gln A and B could induce apoptosis, G2/M-phase cycle arrest, DNA damage and the accumulation of reactive oxygen species (ROS) in HL-60 cells[1]. GlnB inhibits the proliferation of human cervical cancer cells in vitro through the induction of apoptosis andautophagy, which may be mediated by the phosphatidylinositol 4,5 bisphosphate 3 kinase/Akt signaling pathway. Treatment with GlnB inhibits the proliferation of HeLa and SiHa cervical cancer cell lines in a dose dependent manner. GlnB increases the apoptotic cell population of and enhanced poly (ADP ribose) polymerase 1 cleavage. GlnB also induces increased light chain 3 II/I protein cleavage, indicating the induction of autophagy. GlnB treatment increases the expression of phosphatase and tensin homolog and decreases the expression of phosphorylated protein kinase B[2]. Glaucocalyxin B (GLB), one of five ent-kauranoid diterpenoids, significantly decreased the generation of nitric oxide (NO), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) in the lipopolysaccharide (LPS)-activated microglia cells[3].

Cell experiment: | The microglia cells viability is assessed by MTT assay. Cells are seeded in 96-well plates at the density of 5 × 104 cells/well. The cell culture supernatant is discarded after treatment with various agents, and then 30 μL of MTT (0.5 mg/mL) solution is added into each well. After incubation for 4 h at 37 °C, 100 μL of DMSO is added into each well to dissolve the formazan dye, and then the absorbance of solubilized formazan is measured by microplate reader[3]. |
