Anti-Cancer Activity of Resveratrol and Derivatives Produced by Grapevine Cell Suspensions in a 14 L Stirred Bioreactor

2017

International audience; In the present study, resveratrol and various oligomeric derivatives were obtained from a 14 L bioreactor culture of elicited grapevine cell suspensions (Vitis labrusca L.). The crude ethyl acetate stilbene extract obtained from the culture medium was fractionated by centrifugal partition chromatography (CPC) using a gradient elution method and the major stilbenes contained in the fractions were subsequently identified by using a (13)C-NMR-based dereplication procedure and further 2D NMR analyses including HSQC, HMBC, and COSY. Beside δ-viniferin (2), leachianol F (4) and G (4'), four stilbenes (resveratrol (1), ε-viniferin (5), pallidol (3) and a newly characterized…

Cytotoxicity of Labruscol, a New Resveratrol Dimer Produced by Grapevine Cell Suspensions, on Human Skin Melanoma Cancer Cell Line HT-144

2017

IF 2.861; International audience; A new resveratrol dimer (1) called labruscol, has been purified by centrifugal partition chromatography of a crude ethyl acetate stilbene extract obtained from elicited grapevine cell suspensions of Vitis labrusca L. cultured in a 14-liter stirred bioreactor. One dimensional (1D) and two dimensional (2D) nuclear magnetic resonance (NMR) analyses including ¹H, 13C, heteronuclear single-quantum correlation (HSQC), heteronuclear multiple bond correlation (HMBC), and correlation spectroscopy (COSY) as well as high-resolution electrospray ionisation mass spectrometry (HR-ESI-MS) were used to characterize this compound and to unambiguously identify it as a new st…

Hipoacusia súbita: nueva pauta corticoidea intratimpánica precoz

2019

Desde hace unos años, el tratamiento intratimpánico de enfermedades como la hipoacusia súbita o la Enfermedad de Menière ha ido cobrando importancia. Cada vez han sido más los artículos y las conferencias en congresos que han profundizado en la eficacia del mismo. Hasta el momento, estos tratamientos han sido utilizados como terapias de segunda línea o como terapias de rescate ante el fracaso del tratamiento sistémico. No obstante, la efectividad de este tipo de tratamientos es significativa en comparación con placebo. Mientras que en la sordera súbita clásicamente se ha utilizado el tratamiento intratimpánico en pautas de una dosis semanal, el mismo tratamiento en la enfermedad de Menière …
