<p class="Abstract">The present study was performed to investigate the effect of 2-fluorobenzaldehyde retinoic acid conjugate on activation of STAT3 pathway in human glioma cells. The results revealed that the compound exhibited inhibitory effect on the activation of STAT3 induced constitutively and by interleukin-6. The inhibitory effect on STAT3 activation was found to be concentration- and time-dependent. In U373 glioma cells, 2-fluorobenzaldehyde retinoic acid conjugate treatment caused a significant enhancement in the expression of proapoptotic proteins like Bax and Bak. Its treatment inhibited the expression of genes including, cyclin D1, Bcl-2, Bcl-xL, survivin, Mcl-1, and vascular endothelial growth factor (VEGF) in U373 glioma cells. Furthermore, the conjugate inhibited proliferation, induced apoptosis and caused accumulation of cells in G1-G0 phase of cell cycle. Thus, 2-fluorobenzaldehyde retinoic acid conjugate acts as a potent inhibitor of STAT3 activation that can be promising importance for the prevention and treatment of gliomas.</p><p> </p>

Abstract Background: Vigabatrin (VGB) is an approved non-traditional antiepileptic drug that has been revealed to have potential for treating brain tumors; however, its effect on ionic channels in glioma cells remains largely unclear. Methods: With the aid of patch-clamp technology, we investigated the effects of VGB on various ionic currents in the glioblastoma multiforme cell line 13-06-MG. Results: In cell-attached configuration, VGB concentration-dependently reduced the activity of intermediate-conductance Ca2+-activated K+ (IKCa) channels, while DCEBIO (5,6-dichloro-1-ethyl-1,3-dihydro-2H-benzimidazol-2-one) counteracted the VGB-induced inhibition of IKCa channels. However, the activity of neither large-conductance Ca2+-activated (BKCa) nor inwardly rectifying K+ (KIR) channels were affected by the presence of VGB in human 13-06-MG cells. However, in the continued presence of VGB, the addition of GAL-021 or BaCl2 effectively suppressed BKCa and KIR channels. Conclusions: The inhibitory effect of VGB on IKCa channels demonstrated in the current study could be an important underlying mechanism of VGB-induced antineoplastic (e.g., anti-glioma) actions.

Antiviral Activities

Isatis indigoticais widely used in Chinese Traditional Medicine for clinical treatment of virus infection, tumor, and inflammation, yet its antiviral activities remain unclear. This study probed antiviral activity ofI. indigoticaextract and its marker compounds against Japanese encephalitis virus (JEV).I. indigoticamethanol extract, indigo, and indirubin proved less cytotoxic than other components, showing inhibitory effect (concentration-dependent) on JEV replicationin vitro. Time-of-addition experiments proved the extract, indigo, and indirubin with potent antiviral effect by pretreatment (before infection) or simultaneous treatment (during infection), but not posttreatment (after entry). Antiviral action of these agents showed correlation with blocking virus attachment and exhibited potent virucidal activity. In particular, indirubin had strong protective ability in a mouse model with lethal JEV challenge. The study could yield anti-JEV agents.
