Herboxidiene is a potent phytotoxic polyketide with herbicidal and antitumor activities[1]. Herboxidiene binds to SAP155 protein of the SF3b complex and impairs the function of SF3b, which disturbs the pre-mRNA splicing, producing unspliced RNA species of the p27 gene[2]. Herboxidiene has been widely used to upregulate the gene expression of low-density lipoprotein receptor[3].
In vitro, Herboxidiene treatment for 72 hours significantly inhibited the viability of A431, A549, and DLD-1 cells, with IC50 values of 3.7nM, 21nM, and 51nM, respectively[4]. 0.1µM of Herboxidiene treatment for 6 hours inhibited the invasion and tube formation of human umbilical vein endothelial cells (HUVECs) induced by VEGF[5]. Treatment with 1µM Herboxidiene for 6 hours induced the selective splicing of MCL-1 and apoptosis in KOPN-8 cells[6].
In vivo, Herboxidiene treatment via intravenous injection of 1mg/kg significantly reduced tumor growth in mice with SV-T2 xenografts within 4 days[4].

Protocol
| Cell experiment [1]: | |
|
Cell lines |
Human umbilical vein endothelial cells (HUVECs) |
|
Preparation Method |
Human umbilical vein endothelial cells (HUVECs) were cultivated in Endothelial growth medium-2 (EGM-2) supplemented with 10% heat-inactivated fetal bovine serum (FBS) at 37°C in an incubator with 5% CO2. Cells were seeded in a 96-well plate at a density of 3×103 cells/well for 24h, with three replicates for each treatment. Cells were incubated with Herboxidiene (0, 0.001, 0.01, 0.04, and 0.16µM) for 72h, the cell viability was detected. |
|
Reaction Conditions |
0, 0.001, 0.01, 0.04, and 0.16µM; 72h |
|
Applications |
Herboxidiene treatment inhibited the cell viability of HUVECs in a dose-dependent manner. |
| Animal experiment [2]: | |
|
Animal models |
BALB/c-nu/nu mice |
|
Preparation Method |
BALB/c-nu/nu mice (6 weeks old; 18-22g) were maintained in a controlled environment at 22±1°C and 60% relative humidity under a 12h light/dark cycle, and were fed ad libitum. SV-T2 cells were subcutaneously transplanted into the abdomen of BALB/c-nu/nu mice by using a trocar. Eleven days after the transplantation, the growth of the tumor was confirmed. Herboxidiene was administered via a single intravenous injection of a 1mg/kg dose, and the tumor growth was analyzed in mice. |
|
Dosage form |
1mg/kg; once; i.v. |
|
Applications |
Herboxidiene treatment significantly reduced tumor growth in mice with SV-T2 xenografts. |
