OBJECTIVETo evaluate the effect of irbesartan on the proliferation, apoptosis, and VEGF mRNA expression of human umbilical vein cell line EA.hy926 in vitro.
METHODSThe human umbilical vein cell line EA.hyY926 were treated with various concentrations of irbesartan for 24 h. The cell proliferation after the treatment was detected by CCK8 assay, flow cytometry and FITC Annexin V/PI kit were used to detect changes in the cell apoptosis. RT-PCR was used to evaluate the expression of VEGF mRNA.
RESULTSThere were no changes in cell shape with various concentration of irbesartan. CCK-8 assay showed a greater rate of the cell proliferation in irbesartan group than that in control group with a dose-independent manner after 24 h treatment. After incubation with irbesartan, cell proliferation rate was significant (P < 0.05). FCM analysis showed no significantly changes in the cell apoptosis. Irbesartan increased the proliferation of EA.hy926 cells. At concentration of 1 x 10(-4), 1 x 10(-5), 1 x 10(-6) mol/L, VEGF mRNA expression enhanced either (P < 0.05).
CONCLUSIONIrbesartan could promote the proliferation and up-regulated VEGFmRNA expression in EA.hy926 cell line. This result suggested that in addition to antihypertensive effect, angiotensin receptor antagonist might be a novel therapeutic approach to chronic ischemic heart disease as heart failure.

In order to develop potent antidiabetic agents that have inhibitory effect to a-glucosidase, twelve β-acetamido ketone derivatives such as N-{[(substituted-4-oxo-thiochroman-3-yl)phenyl]-methyl}acetamide are designed and synthesized through one-pot Dakin-West reaction. Their chemical structures are confirmed by 1H NMR, 13C NMR, IR and HR-MS. In vitro α-glucosidase inhibition assays of compounds 4a-41 were carried out using glucose oxidase method. The result indicated that most of them possess inhibitory activity in vitro. Compound 4k showed the most potent inhibitory activity with 87.3% inhibition of α-glucosidase at the concentration of 5.39 mmol x L(-1). The structure-activity relationship of these β-acetamido ketone derivatives was discussed preliminarily. Moreover, the molecular docking method was used to study the interaction mode of compound 4k and α-glucosidase. Our results will be helpful for designing of α-glucosidase inhibitors in the future.

BACKGROUNDTreatment for malignant glioma generally consists of cytoreductive surgery followed by radiotherapy and chemotherapy. In this study, we intended to investigate the effects of 2-propylpentanoic acid (VPA), a histone deacetylase inhibitor, on chemosensitivity and radiosensitivity in human glioma cell lines.
METHODSHuman glioma cell lines, T98-G, and SF295, were treated with temozolomide (TMZ) or irradiation (IR), with or without VPA (1.0 mmol/L). Then, cytotoxicity and clonogenic survival assay was performed. Cell cycle stage, apoptosis, and autophagy were also detected using flow cytometry and dansyl monocadaverin (MDC) incorporation assay. One-way analysis of variance (ANOVA) and t-test were used to analyze the differences among variant groups.
RESULTSMild cytotoxicity of VPA was revealed in both cell lines, T98-G and SF295, with the 50% inhibiting concentration (IC50) value of (3.85 ± 0.58) mmol/L and (2.15 ± 0.38) mmol/L, respectively; while the IC50 value of TMZ was (0.20 ± 0.09) mmol/L for T98-G and (0.08 ± 0.02) mmol/L for SF295. Moreover, if combined with VPA (1.0 mmol/L) for 96 hours, the sensitivity of glioma cells to TMZ was significant increased (P < 0.05). The surviving fractions at 2 Gy (SF2) of T98-G and SF295 cells exposed to IR alone were 0.52 and 0.58. However, when VPA was combined with IR, the SF2 of T98-G and SF295 dropped to 0.39 (P = 0.047) and 0.49 (P = 0.049), respectively. Treatment with VPA plus TMZ or IR also resulted in a significant decrease in the proportion of cells in the G2 phase and increased apoptotic rates as well as autophagy in T98-G and SF295 cell lines (P < 0.01).
CONCLUSIONVPA may enhance the activities of TMZ and IR on glioma cells possibly through cell cycle block and promote autophagy, and thus could be a potential sensitizer of glioma treatment.
