Zusammenfassung
Anwendungen cyclodextrin-veredelter Textilien im dermatologischen oder kosmetischen
Bereich machen eine Abklärung der Hautverträglichkeit der verwendeten Cyclodextrine
notwendig. In der vorliegenden Arbeit wurde der Einfluss von unsubstituierten Cyclodextrinen
und Cyclodextrin-Derivaten auf das Proliferationsverhalten epidermaler Zellen (HaCaT-Keratinozyten)
untersucht. Während α- und γ-Cyclodextrine und ihre Derivate auch in hoher Konzentration
(1 % w/v) gut von den Zellen toleriert werden, wirken β- und Methyl-β-Cyclodextrine
dosisabhängig stark zytotoxisch. Diese Eigenschaften sollten beim In-vivo- Einsatz von Cyclodextrinen im dermatologischen Bereich unbedingt berücksichtigt werden.
Abstract
Applications of textiles finished with cyclodextrins for dermatological or cosmetic
purposes require an assessment on the skin tolerability of the fixed cyclodextrins.
In the present work, the influence of natural and chemically modified cyclodextrins
on the proliferation behavior of a human epidermal cell line (HaCaT keratinocytes)
was investigated. It was shown, that α- and γ-cyclodextrin were well tolerated by
the cells even at high concentrations (1 % w/v). However, β- and methyl-β-cyclodextrin
induce cytotoxic effects in a dose-dependent manner. For in vivo applications of β- and methyl-β-cyclodextrins these findings should be taken into
consideration.
