    An the present study we evaluated the effect of natural sesquiterpene lactones of plants of the genus Inula on the cells of neuroblastoma SK-N-MC under conditions of toxic stress induced by H2O2 and glutamate. Lactones increased cell survival under these conditions and the leader compounds were identified in this series. A putative mechanism for the protective action of lactones on cells under condition toxic stress has been proposed.ИсслСдовано дСйствиС ΠΏΡ€ΠΈΡ€ΠΎΠ΄Π½Ρ‹Ρ… сСсквитСрпСновых Π»Π°ΠΊΡ‚ΠΎΠ½ΠΎΠ² растСний Ρ€ΠΎΠ΄Π° Inula Π½Π° ΠΊΠ»Π΅Ρ‚ΠΊΠΈ нСйробластомы SK-N-MC Π² условиях токсичСского стрСсса, ΠΈΠ½Π΄ΡƒΡ†ΠΈΡ€ΠΎΠ²Π°Π½Π½ΠΎΠ³ΠΎ H2O2 ΠΈ Π³Π»ΡƒΡ‚Π°ΠΌΠ°Ρ‚ΠΎΠΌ.

    The results of in vitro studies demonstrate cytotoxic activity alantolactone and isoalantolactone, presented in the elecampane plant (Inula helenium) of the natural sesquiterpene lactones. These compounds show toxicity against human cancer cell lines: MS, A549, HCT116, MCF7, RD and K562. The involvement of the p53 signaling pathway in the death of tumor cells, as well as the contribution of reactive oxygen species (ROS) formation during cell death, was studied.ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½Ρ‹ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ исслСдований in vitro цитотоксичСской активности ΠΏΡ€ΠΈΡ€ΠΎΠ΄Π½Ρ‹Ρ… сСсквитСрпСновых Π»Π°ΠΊΡ‚ΠΎΠ½ΠΎΠ² – Π°Π»Π°Π½Ρ‚ΠΎΠ»Π°ΠΊΡ‚ΠΎΠ½Π° ΠΈ ΠΈΠ·ΠΎΠ°Π»Π°Π½Ρ‚ΠΎΠ»Π°ΠΊΡ‚ΠΎΠ½Π°, содСрТащихся Π² растСнии дСвясил высокий (Inula helenium).

    The paper contains analytical overview of the most important unique/critical objects and the computational analysis problems of the mechanical safety, carried out by the team of Research & Development Centre StaDyO (StaDyO R&D Centre) researchers for the last two years (2016-2018). Corresponding complex coupled problems of continuum mechanics were solved with the use of contemporary methods and models of numerical modeling (nonlinear models, coupled problems, substructures, submodeling, etc.), implemented in verified software complexes. Some of these results are briefly considered and analyzed. Conclusions about the main directions of further research and development are presented as well.
