Silymarin, an extract of Silybum marianum seeds, and the constituent flavonolignans silybin, silydianin and silychristin, as well as the flavonol quercetin, protected rat heart microsomes and mitochondria against iron-dependent doxorubicin induced lipid peroxidation. Quercetin was found to be more potent than either silymarin or its three constituents,(More)
The neonatal rat cardiomyocyte model enables heart researchers to study and understand the morphological, biochemical and electrophysiological characteristics of the heart. This model offers a broad spectrum of experiments, such as studies of contraction, ischaemia, hypoxia and the toxicity of various compounds. This review examines the methodology for the(More)
Silymarin, an extract of fl avonolignans 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 fl avonolignans did not exert cytotoxicity in the range 25-100(More)
The chemoprotective effects of caffeic (CA), chlorogenic (CHA) and rosmarinic (RA) acids were tested against the toxicity of doxorubicin (DOX) in neonatal rat cardiomyocytes and the iron-dependent DOX induced lipid peroxidation of heart membranes, mitochondria and microsomes. The protectivity of these acids was compared with dexrazoxan, used as an adjuvant(More)
Flavonoids are found universally in plants and act as free radical scavenging and chelating agents with antiinflammatory, antiischemic, vasodilating and chemoprotective properties. In this study, the antilipoperoxidative and cytoprotective effects of apigenin, baicalein, kaempferol, luteolin and quercetin against doxorubicin-induced oxidative stress were(More)
The cardioprotective effect of Prunella vulgaris ethylacetate fraction (PVEF) and its constituent rosmarinic acid (RA) was evaluated on isolated rat cardiomyocytes subjected to doxorubicin-induced oxidative stress. The cytoprotectivities of PVEF and RA were concentration-dependent in the range of 0.005 to 0.05 mg/ml and the effect of PVEF correlated with(More)
