The new synthetically prepared quinolone derivative 7-ethyl 9-ethyl-6-oxo-6,9-dihydro[1,2,5]selenadiazolo [3,4-h]quinoline-7-carboxylate (E2h) showed in our previous study cytotoxic effects towards tumor cells and immunomodulatory activities on RAW 264.7 cell line murine macrophages. E2h may have a potential use as a novel chemotherapeutic agent with immunomodulatory properties and the ability to induce apoptotic death of cancer cells. The aim of the present study was to examine the antiproliferative/cytotoxic activities of E2h on human non-cancer fibroblast BHNF-1 cells and reconstructed human epidermis EpiDerm™. Further the effects of E2h on tissue structure and morphology were examined. Cytotoxic/toxic studies showed that selenadiazoloquinolone is not toxic on normal human fibroblast cells BHNF-1 and dimensional skin constructs EpiDerm™. Evaluation of morphological changes in EpiDerm™ showed no change in the construction and morphology of skin tissue treated by E2h compared to control.
