Galanty A., Popiół J., Paczkowska-Walendowska M., Studzińska-Sroka E., Paśko P., Cielecka-Piontek J., Pękala E. & Podolak I. (2021): (+)-Usnic acid as a promising candidate for a safe and stable topical photoprotective agent - Molecules, 26(17): 5224 [11 p.]

The study aimed to examine whether usnic acid—a lichen compound with UV-absorbing properties—can be considered as a prospective photoprotective agent in cosmetic products. Moreover, a comparison of two usnic acid enantiomers was performed to preselect the more effective compound. To meet this aim, an in vitro model was created, comprising the determination of skin-penetrating properties via skin-PAMPA assay, safety assessment to normal human skin cells (keratinocytes, melanocytes, fibroblasts), … Read more...

Krajka‑Kuźniak V., Paluszczak J., Kleszcz R. & Baer‑Dubowska W. (2021): (+)‑Usnic acid modulates the Nrf2‑ARE pathway in FaDu hypopharyngeal carcinoma cells - Molecular and Cellular Biochemistry, 476: 2539–2549

Naturally occurring phytochemicals of different origin and structure, arctigenin, bergenin, usnic acid and xanthohumol, were shown to affect Nrf2 pathway in the context of various diseases, but their effect on this pathway in cancer cells was not extensively investigated. This study aimed to evaluate the effect of these compounds on Nrf2 expression and activation in hypopharyngeal FaDu squamous cell carcinoma cells. FaDu cells were treated with 2 or 10 μM arctigenin, bergenin, (+)- usnic acid … Read more...

Cordeiro L.M.C., Beilke F., Bettim F.L., Reinhardt V.F., Rattmann Y.D. & Iacomini M. (2012): (1 → 2) and (1 → 6)-linked β-d-galactofuranan of microalga Myrmecia biatorellae, symbiotic partner of Lobaria linita - Carbohydrate Polymers, 90(4): 1779-1785

A structural study of the cell wall polysaccharides of Myrmecia biatorellae, the symbiotic algal partner of the lichenized fungus Lobaria linita was carried out. It produced a rhamnogalactofuranan, with a (1 → 6)-β-d-galactofuranose in the main-chain, substituted at O-2 by single units of β-d-Galf, α-l-Rhap or by side chains of 2-O-linked β-d-Galf units. The structure of the polysaccharide was established by chemical and NMR spectroscopic analysis, and is new among natural polysaccharides. … Read more...
