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.
