生物活性

Fasentin, a potent glucose uptake inhibitor, inhibits GLUT-1/GLUT-4 transporters. Fasentin preferentially inhibits GLUT4 (IC50=68 μM) over GLUT1. Fasentin is a death receptor stimuli (FAS) sensitizer and sensitizes cells to FAS-induced cell death. Fasentin is also a tumor necrosis factor (TNF) apoptosis-inducing ligand sensitizer. Fasentin blocks glucose uptake in cancer cell lines and has anti-angiogenic activity[1][2][3].

体外研究
(In Vitro)

Fasentin (0.1-1000 μM; 72 hours) inhibits endothelial, tumour and fibroblast cell growth without inducing cell death[1].
Fasentin (25-100 μM; 16-24 hours) induces a cell cycle arrest in G0/G1 phase and reduces the cell number in S phase in a dose-dependent manner[1].
Fasentin (50 μM; 16 hours) alters expression of genes associated with glucose deprivation such as AspSyn and PCK-2[2].
Fasentin (15, 30, 80 μM; pretreatment 1 hour) induces glucose deprivation, partially blocks glucose uptake in PPC-1, DU145, and U937 cells[2].
Fasentin (100 μM; 16 hours) does not affect the migratory capability of endothelial cells[1].
Fasentin (25-100 μM; 16 hours) lowers levels of phospho-ERK in HMECs, indicating a partial inhibition on the ERK signalling pathway, even though the effect is not statistically significant. Fasentin does not inhibit the tyrosine kinase activity of VEGFR2[1].
Fasentin interacts with a unique site in the intracellular channel of GLUT1[3].

Cell Viability Assay[1]

Cell Line: Three types of endothelial cells ECs (HMEC, human microvascular endothelial cells; HUVEC, human umbilical vein endothelial cells; and BAEC, bovine aortic endothelial cells), three human tumour cell lines (MDA-MB-231 and MCF7 breast carcinoma cells, and HeLa cervix adenocarcinoma cells), and human gingival fibroblasts (HGF)
Concentration: 0.1, 1, 10, 100, 1000 μM
Incubation Time: 72 hours
Result: Inhibited endothelial, tumour and fibroblast cell growth (IC50=26.3-111.2 μM) without inducing cell death.

Cell Cycle Analysis[1]

Cell Line: HMECs
Concentration: 25, 50, 100 μM
Incubation Time: 16, 24 hours
Result: Induced a cell cycle arrest in G0/G1 phase and reduced the cell number in S phase in a dose-dependent manner.
Did not increase the subG1 population.

RT-PCR[2]

Cell Line: PPC-1 cells[2]
Concentration: 50 μM
Incubation Time: 16 hours
Result: Altered expression of genes associated with glucose deprivation such as AspSyn and PCK-2 not FLIP mRNA expression.
