GABA_A receptor^[1]

(-)-Securinine is a major plant-derived alkaloid and also a GABA_A receptor antagonist. (-)-Securinine is significantly potent on HeLa cells growth inhibition with IC₅₀ values of 7.02±0.52 μg/mL (32.3 μM). (-)-Securinine induces apoptosis in a dose-dependent manner in the tested cells, increases the percentage of ROS positive cells and depolarized cells as well as stimulates the activity of ERK1/2, caspase-9 and -3/7. (-)-Securinine also induces cell cycle arrest in S phase. Real-time PCR analysis shows high expression of tumor necrosis factor receptor superfamily (TNFRSF) genes in the cells stimulated with (-)-Securinine^[1].

In this tumor model, tumor growth is significantly impaired with (-)-Securinine treatment indicating that (-)-Securinine has potential as an Acute Myeloid Leukemia (AML) therapeutic. (-)-Securinine treated mice (n=5 mice, bilateral tumors), exhibit an average of more than 75% smaller tumors than vehicle treated mice at the end of the study period^[2].

The cells are seeded in 12-well plates (1×10⁵/well) and treated with (-)-Securinine at concentrations of 1.0 to 50.0 μg/mL. The control cells are exposed to DMSO at a concentration of 0.5% (v/v). After 6 h and 24 h of exposure, the activity of caspase-9 is measured by Caspase-Glo 9 Assay Kit and Glomax Multi+ Detection System, according to the manufacturer’s instruction. The activity of caspase-3/7 is assessed after 24 h of exposure the cells to (-)-Securinine. Then the cells are harvested and prepared using Muse Caspase-3/7 Assay Kit according with the manufacturer’s protocol. The stained cells are analyzed by Muse Cell Analyzer. The experiments are performed at least in three independent repeats^[1].

The viability of the cells is determined by MTT assay. HeLa cells are seeded in 96-well plates at a density of 5×10³ cells/well and treated for 24 h with (-)-Securinine in the concentration range of 1.0 to 20.0 μg/mL. The maximal concentrations of the solvents used in all the MTT experiments are 5.0% (v/v) and 1.0% (v/v) for methanol and DMSO, respectively. The absorption of the obtained formazan solution is measured with a plate reader. The viability results are presented as IC₅₀ mean values of at least three independent experiments^[1].

6 week old female nude mice are used and injected bilaterally s.c. with 10×10⁶ HL-60 cells. (-)-Securinine treatment is started 10 days after tumor cell injection. Palpable tumors are present for the established tumor model prior to initiating drug treatment. 15 mg/kg of (-)-Securinine or vehicle (30 µL of DMSO and 70 µL of water) are injected i.p. 2 or 3 times a day for 5 days followed by once a day for two days. This injection schedule is repeated for two additional weeks^[2].
