The cytotoxicity-guided study of the dichloromethane and ethanol extracts of Thymus mastichina L. using the HCT colon cancer cell line allowed the identification of nine compounds, sakuranetin (1), sterubin (2), oleanolic acid (3), ursolic acid (4), lutein (5), beta-sitosterol (6), rosmarinic acid
Cancer is one of the biggest problems in public health worldwide. Plants have been shown important role in anticancer research. Viscum album L. (Santalaceae), commonly known as mistletoe, is a semi-parasitic plant that grows on different host trees. In complementary medicine, extracts from European
Alzheimer's disease (AD) is a high-incidence neurodegenerative disease with complex and diverse pathogenesis. With aging of the population and continuous improvement of living standards, the incidence of AD is on the increase. Therefore, there is need to develop more effective AD drugs in order to
Sakuranetin belongs to the group of methoxylated flavanones. It is widely distributed in Polyomnia fruticosa and rice, where it acts as a phytoalexin. Other natural sources of this compound are, among others, grass trees, shrubs, flowering plants, cheery, and some herbal drugs, where it has
Activity-based fractionation of Eriodictyon californicum resulted in the isolation of 12 flavonoids that inhibit the metabolism of the carcinogen benzo[a]pyrene by hamster embryo cells in tissue culture. One was identified as a new flavanone, 3'-methyl-4'-isobutyryleriodictoyol [1], on the basis of
The bark of Prunus yedoensis is used in antitussive medicines and in oral herbal formulations for inflammatory skin disorders. In the present study, we explored whether P. yedoensis bark extract (PYE) and its solvent partitioned fractions could modulate lipopolysaccharide (LPS)-induced tumor
Double-strand breaks (DSBs) may result from endogenous (e.g., reactive oxygen species, variable (diversity) joining, meiotic exchanges, collapsed replication forks, nucleases) or exogenous (e.g., ionizing radiation, chemotherapeutic agents, radiomimetic compounds) events. DSBs disrupt the integrity
Photooxidative damage affects cellular lipids, proteins and DNA in addition to being involved in the pathobiochemistry of erythema formation, premature skin aging, photodermatoses development and skin cancer. Phenolic compounds, flavonoids and hydroxycinnamic acid esters protect plant tissues
Four interconverting flavanone glycosides [(2R)- and (2S)-3',4',5,6-tetrahydroxyflavanone 7-O-β-D-glucopyranoside, and (2R)- and (2S)-3',4',5,8-tetrahydroxyflavanone 7-O-β-D-glucopyranoside], in addition to eight known flavonoids [naringenin, asebogenin, sakuranetin, 6-hydroxyluteolin
The objective of the present study was to examine the antitumor efficacy of the ethanol extract from Artemisia dracunculus as well as the compounds isolated from it on cultured EC‑109 esophageal squamous cell carcinoma (ESCC) cells. Apoptotic activities of the compounds were also studied using flow
The multidrug resistance (MDR) proteins that belong to the ATP-binding cassette superfamily such as P-glycoprotein (P-gp) and MRP1, are present in a majority of human tumors and constitute an important cause of therapeutic failure. Selective inhibitors of the MDR-efflux proteins may improve the
