    Chemoprotective effect of plant phenolics against anthracycline-induced toxicity on rat cardiomyocytes. Part I. Silymarin and its flavonolignans

  • Original language description

    Silymarin, an extract of flavonolignans from the dried fruits of milk thistle (Silybum marianum L. Gaertneri) and its constituents silibinin, dehydrosilibinin, silychristin and silydianin were tested for protective effects on rat cardiomyocytes exposed to doxorubicin. Silymarin and individual flavonolignans did not exert cytotoxicity in the range 25-100 #m (incubation 9 h). Dehydrosilibinin was tested only at 25 #m concentration due to its low solubility. All substances increased the cell ATP level. Silymarin and flavonolignans displayed a dose-dependent cytoprotection against doxorubicin (100 #m, incubation 8 h). The protective effects of silymarin, silibinin, dehydrosilibinin and silychristin were comparable to that of dexrasoxane, while silydianin exerted the best protective effect. The ability of silymarin complex and its components to protect cardiomyocytes against doxorubicin-induced oxidative stress is due mainly to their cell membrane stabilization effect, radical scavenging an

    Chemoprotektivní vliv rostlinných fenolů vůči toxicitě indukované anthracyklinem u potkaních kardiomyocytů. Část II. Silymarin a jeho flavonolignany

  • Czech description

    Cytoprotektivní efekt silymarinu, extraktu flavonolignanů ze semen ostropestřce mariánského (Silybum marianum L., Gaertneri) a jeho obsahových látek silibininu, dehydrosilibininu, silychristinu a silydianinu byl testován na potkaních kardiomyocytech intoxikovaných doxorubicinem. Silymarin a jednotlivé flavonolignany nevykazovaly toxický efekt v rozsahu 25-100 mM (inkubace 9 hod). Dehydrosilybin byl testován pouze do koncentrace 25 mM díky své nízké rozpustnosti. Všechny látky zvyšovaly v buňkách hladinuATP. Silymarin a flavonolignany vykazovaly koncentračně závislý cytoprotektivní účinek vůči doxorubicinu (100 mM, 8 hod). Protektivní efekt silymarinu, silibininu, dehydrosilibininu a silychristinu byl srovnatelný s účinkem dexrazoxanu, zatímco silydianin vykazoval nejlepší ochranný efekt. Schopnost silymarinového komplexu a jeho obsahových látek chránit kardiomyocyty před oxidativním stresem vyvolaným doxorubicinem je založena na jejich schopnosti stabilizovat membrány, vychytávat radi
