    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 main pharmacokinetic parameters of a new stimulator of cognitive brain functions, OSPL – 502 have been determined: area under the concentration-time curve, elimination rate constant, half-elimination period, time to reach the maximum concentration, maximum concentration, volume distribution, total clearance and bioavailability of the dosage form. The main metabolites of the active substance of the dosage form of the new stimulator of cognitive functions OSPL – 502 have been analyzed. The data obtained predict the effects of the drug in humans relevant for further clinical investigation.ΠŸΡ€ΠΎΠ²Π΅Π΄Π΅Π½Π½ΠΎΠ΅ исслСдованиС фармакокинСтичСских ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€ΠΎΠ² лСкарствСнной Ρ„ΠΎΡ€ΠΌΡ‹ Π½ΠΎΠ²ΠΎΠ³ΠΎ стимулятора ΠΊΠΎΠ³Π½ΠΈΡ‚ΠΈΠ²Π½Ρ‹Ρ… Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΉ ΠΌΠΎΠ·Π³Π° OSPL-502 ΠΏΠΎΠ·Π²ΠΎΠ»ΠΈΠ»ΠΎ ΠΎΠΏΡ€Π΅Π΄Π΅Π»ΠΈΡ‚ΡŒ основныС фармакокинСтичСскиС ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€Ρ‹ (ΠΏΠ»ΠΎΡ‰Π°Π΄ΡŒ ΠΏΠΎΠ΄ ΠΊΡ€ΠΈΠ²ΠΎΠΉ β€œΠΊΠΎΠ½Ρ†Π΅Π½Ρ‚Ρ€Π°Ρ†ΠΈΡ-врСмя”; константа скорости элиминации; ΠΏΠ΅Ρ€ΠΈΠΎΠ΄ полуэлиминации; врСмя достиТСния максимальной ΠΊΠΎΠ½Ρ†Π΅Π½Ρ‚Ρ€Π°Ρ†ΠΈΠΈ; максимальная концСнтрация; ΠΎΠ±ΡŠΡ‘ΠΌ распрСдСлСния; ΠΎΠ±Ρ‰ΠΈΠΉ клирСнс).

    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 aqueous extract of blueberry leaves inhibits the glutamate-induced Ca2+ influx into the synaptosomes of rat brain neurons and the IC50 value of this process is close to the IC50 for MK-801, a well-known noncompetitive antagonist of glutamate NMDA subtype receptors. The aqueous extract of blueberry leaves protected the cultured neurons of the rat cerebral cortex from the neurotoxic effect of glutamate, and the inhibition intensity depended on the incubation time with the extract.Π’ΠΎΠ΄Π½Ρ‹ΠΉ экстракт Π»ΠΈΡΡ‚ΡŒΠ΅Π² Ρ‡Π΅Ρ€Π½ΠΈΠΊΠΈ ΠΈΠ½Π³ΠΈΠ±ΠΈΡ€ΡƒΠ΅Ρ‚ Π³Π»ΡƒΡ‚Π°ΠΌΠ°Ρ‚-ΠΈΠ½Π΄ΡƒΡ†ΠΈΡ€ΠΎΠ²Π°Π½Π½Ρ‹ΠΉ Π²Ρ…ΠΎΠ΄ ΠΈΠΎΠ½ΠΎΠ² Π‘Π°2+ Π² синаптосомы Π½Π΅ΠΉΡ€ΠΎΠ½ΠΎΠ² ΠΌΠΎΠ·Π³Π° крыс, ΠΈ IC50 этого процСсса Π±Π»ΠΈΠ·ΠΊΠ° ΠΊ IC50 для MK-801 – извСстного Π½Π΅ΠΊΠΎΠ½ΠΊΡƒΡ€Π΅Π½Ρ‚Π½ΠΎΠ³ΠΎ антагониста Π³Π»ΡƒΡ‚Π°ΠΌΠ°Ρ‚Π½Ρ‹Ρ… Ρ€Π΅Ρ†Π΅ΠΏΡ‚ΠΎΡ€ΠΎΠ² NMDA-ΠΏΠΎΠ΄Ρ‚ΠΈΠΏΠ°.

    Compounds that act on mitochondrial functions are considered as promising drugs for the treatment of neurodegenerative diseases and age-related dementias. As a basis for the creation of such potential drugs, bioisosteric cinnamic acid analogs and polymethoxybenzene derivatives were selected. Derivatives of cinnamic acid have a wide range of biological activities, which can be important for drugs aimed at the treatment of neurodegenerative diseases, in particular Alzheimerβ€²s disease. In this work, the neuroprotective activity of bioisosteric cinnamic acid analogs and polymethoxybenzene derivatives was studied. Among the compounds studied, lead substances 3, 4, and 7 have been identified. These compounds show no intrinsic toxicity and have a neuroprotective effect on the cellular model of neurodegeneration associated with calcium stress. The mechanism of their cytoprotective activity is probably due to the influence on mitochondrial functions, because these compounds effectively suppress the calcium-induced process of mitochondrial permeability jump. In addition, one of the substances investigated (7) has antioxidant properties, showing the ability to inhibit lipid peroxidation (LPO) of rat brain homogenate, which may be an additional mechanism of neuroprotective effect. The data obtained make it possible to recommend the investigated substances as a basis for the creation of effective neuroprotective drugs capable of influencing early stages of the development of neurodegenerative diseases.БоСдинСния, Π½Π°ΠΏΡ€Π°Π²Π»Π΅Π½Π½ΠΎ Π΄Π΅ΠΉΡΡ‚Π²ΡƒΡŽΡ‰ΠΈΠ΅ Π½Π° ΠΌΠΈΡ‚ΠΎΡ…ΠΎΠ½Π΄Ρ€ΠΈΠ°Π»ΡŒΠ½Ρ‹Π΅ Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠΈ, Ρ€Π°ΡΡΠΌΠ°Ρ‚Ρ€ΠΈΠ²Π°ΡŽΡ‚ΡΡ ΠΊΠ°ΠΊ пСрспСктивныС лСкарствСнныС ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚Ρ‹ для лСчСния Π½Π΅ΠΉΡ€ΠΎΠ΄Π΅Π³Π΅Π½Π΅Ρ€Π°Ρ‚ΠΈΠ²Π½Ρ‹Ρ… Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ ΠΈ возрастных Π΄Π΅ΠΌΠ΅Π½Ρ†ΠΈΠΉ.

    Novel 3,5-bis(arylidene)-4-piperidones modified with diethyl[(aryl)methyl]phosphonate moiety attached to the piperidone nitrogen atom have been synthesized by crotonic condensation of aromatic aldehydes with diethyl[(4-oxopiperidin-1-yl)(aryl)methyl]phosphonates in the presence of LiClO4/Et3N system or acetonitrile solution of boron trifluoride etherate. The synthesized phosphonate derivatives of 3,5-bis(arylidene)-4-piperidone series displayed inhibitory properties toward RD, PC3, HCT116, and MCF7 human cancer cell lines with IC50 values in the range of 2.5–8.5 ΞΌM, as assessed by an in vitro 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay.
