L. exerts antineurodegenerative and antioxidant activities and induces prooxidant effect in glioblastoma cell line.

Despite the significant advances in drug development we are witnessing the inability of health systems to combat both neurodegenerative diseases and cancers, especially glioblastoma. Hence, natural products are comprehensively studied in order to provide novel therapeutic options. This study aimed to explore anti-neurodegenerative and anti-glioblastoma potential of extract of L. using model systems. It was found that the methanol extract of was able to efficiently reduce activities of enzymes linked to neurodegenerative disease including acetylcholinesterase, butyrylcholinesterase and tyrosinase. Furthermore, extract has shown excellent antioxidant potential, as evidenced by six different methods. Analysis of cytotoxic effect of extract on A172 glioblastoma cell line revealed that the concentration of the extract necessary for 50 % inhibition of A172 growth (IC) was 710 μg/mL. The extract did not induce changes in proliferation and morphology of A172 glioblastoma cells. On the other side, production of ROS was increased in A172 cells treated with the extract. Observed cytotoxic effect of extract might be based on increase in ROS generation upon treatment. Quantitative chemical analysis revealed the presence of twelve different polyphenols with the 3--caffeoylquinic acid being the most abundant. This study provided scientific evidence for further exploration of as a promising natural anti-neurodegenerative therapeutic option.
