Table 1 Anticancer activities of CBF – in vitro and in vivo studies summary.
| Cancer | Cell lines/model | Activity | Mechanism(s) of action | Application | Reference |
|---|---|---|---|---|---|
| HepG2 | LD=170 ng/L(12 h)LD=78 ng/L (24 h)LD=40 ng/L (48 h) | Upregulates the p53 pathway and down-regulates the Akt and ERK pathways | In vitro | []16 | |
| HepG2 | IC=86.025 μM | Downregulation of prosurvival proteins (Bcl-2) and upregulation of the proapoptotic proteins (Fas and Bax) | In vitro | []11 | |
| Nude mice bearing HepG2 cells | 1.14 mg/kg CBF (intraperitoneal route every two day for 20 doses), tumors weight decreased | In vivo | []11 | ||
| Huh-7 | 1 μmol/L viability rate was 74.5±4.5% (12 h), 1 μmol/L viability rate was 53.7±3.8% (24 h), 1 μmol/L viability rate was 27.9±2.3% (36 h) | Triggers defects in spindle formation and cap-dependent translation by inhibiting the AURKA-mTOR-eIF4E Axis | In vitro | []17 | |
| Nude mice bearing Huh-7 cells | 10 mg/kg CBF (intratumorally injected for 21 days), tumors weight decreased | In vivo | []17 | ||
| U2OS | Inhibits the viability | Induces cell cycle arrest at G2/M phases and induces apoptosis via inhibition of the GSK-3β/NF-κB pathway. | In vitro | []18 | |
| MG63 | Inhibits the viability | In vitro | []18 | ||
| SaOS-2 | Inhibits the viability | In vitro | []18 | ||
| U2OS | Inhibits the viability | Downregulates the stem-like properties of osteosarcoma cells, thus inhibiting the process of tumorigenesis by inhibiting the IL-6-OPN-STAT3 pathway | In vitro | []19 | |
| MG63 | Inhibits the viability | In vitro | []19 | ||
| U2OS | IC=120 mg/L (24 h) | Triggers apoptosis and autophagic cell death via activation of the ROS/JNK/p-38 axis | In vitro | []20 | |
| A375 | IC=0.2 μg/mL (24 h) | Induces cell cycle arrest at the G2/M phase and induces apoptosis by inhibiting the PI3K/Akt pathway | In vitro | []21 | |
| B16 | Inhibits the viability | In vitro | []21 | ||
| OCM1 | IC=0.8023 μM (48 h) | CBF arrested the cell cycle in the G1 phase and induces apoptosis via intrinsic apoptosis pathway | In vitro | []22 | |
| Nude mice bearing OCM1 cells | 5 mg/kg CBF (injected once a day for 7 days), after 30 days, the mice were killed, the tumors weight decreased | In vivo | []22 | ||
| HCT116 | IC=0.7821uM (48 h) | Promotes cell apoptosis and inhibits the invasion and metastases via STAT3 signaling pathway | In vitro | []23 | |
| RKO | IC=0.3642uM (48 h) | In vitro | []23 | ||
| SW480 | IC=0.1822uM (48 h) | In vitro | []23 | ||
| Nude mice bearing HCT116 cells | 0.5 or 1.0 mg/kg CBF (intraperitoneal route every other day for 7 doses), the tumors weight decreased | In vivo | []23 | ||
| NB4 | Inhibits the viability | Induces cell apoptosis and PML-RARA degradation by inhibiting the β-catenin signaling pathway | In vitro | []26 | |
| NB4-R1 | Inhibits the viability | In vitro | []26 | ||
| HK-1 | IC=0.061 μg/ml | Induces cell cycle arrest at the S phase and induces apoptosis through the mitochondrial apoptosis pathway | In vitro | []27 | |
| 5–8F | 446.0 nM | Induces ENKUR to repress the β-catenin/c-Jun/MYH9 signal and thus decreased UBE3A-mediated p53 ubiquitination degradation, ultimately, epithelial-mesenchymal transition signal is inactivated to suppress nasopharyngeal carcinoma metastasis | In vitro | []28 | |
| HONE-1 | 627.6 nM | In vitro | []28 | ||
| U266 | Inhibits the viability | Inhibits ROS-mediated MAPKs signaling pathway and this led to the down-regulation of various gene products that mediate tumor cell survival, proliferation, metastasis and angiogenesis | In vitro | []29 | |
| SGC-7901 | 0.24 mM (24 h) | Induces cell apoptosis and inhibition of autophagy enhances CBF-induced apoptosis | In vitro | []30 | |
| MCF-7 | 0.94±0.08 μM (24 h)0.44±0.12 μM (48 h)0.22±0.03 μM (72 h) | Induces cell cycle arrest at the G1 phase and induces apoptosis through the mitochondrial apoptosis pathway | In vitro | []31 |
