Hyaluronic acid in complexes with surfactants: The efficient tool for reduction of the cytotoxic effect of surfactants on human cell types.

The cationic surfactants carbethoxypendecinium bromide (Septonex) and cetyltrimethylammonium bromide (CTAB) are known to be harmful for certain cell types (bacteria, fungi, mammal cells, etc.). Colloidal complexes of these surfactants with negatively-charged hyaluronic acid (HyA) were prepared for potential drug and/or universal delivery applications. The complexes were tested for their cytotoxic effect on different human cell types - osteoblasts, keratinocytes and fibroblasts. Both the CTAB-HyA and Septonex-HyA complexes were found to reduce the cytotoxicity induced by surfactants alone concerning all the tested concentrations. Moreover, we suggested the limits of HyA protection provided by the surfactant-HyA complexes, e.g. the importance of the amount of HyA applied. We also determined the specific sensitivity of different cell types to surfactant treatment. Keratinocytes were more sensitive to CTAB, while osteoblasts and fibroblasts were more sensitive to Septonex. Moreover, it was indirectly shown that CTAB combines lethal toxicity with cell metabolism induction, while Septonex predominantly causes lethal toxicity concerning fibroblasts. This comprehensive study of the effect of surfactant-HyA complexes on various human cell types revealed that HyA represents a useful CTAB or Septonex cytotoxic effect modulator at diverse levels. Potential applications for these complexes include drug and/or nucleic acid delivery systems, diagnostic dye carriers and cosmetics production. Copyright © 2017 Elsevier B.V. All rights reserved.
