Comparative Anticancer Potentials of Taxifolin and Quercetin Methylated Derivatives against HCT-116 Cell Lines: Effects of -Methylation on Taxifolin and Quercetin as Preliminary Natural Leads.

Six flavonoids present in , i.e., 7,3'-di--methyltaxifolin (), 3'--methyltaxifolin (), 7--methyltaxifolin (), taxifolin (), 3--methylquercetin (), and quercetin (), were tested for their anticancer activities.

Proposed Mechanism for Emodin as Agent for Methicillin Resistant Staphylococcus Aureus: In Vitro Testing and In Silico Study.

In the search for a new anti-MRSA lead compound, emodin was identified as a good lead against methicillin-resistant (MRSA). Emodin serves as a new scaffold to design novel and effective anti-MRSA agents. Because rational drug discovery is limited by the knowledge of the drug target, α-hemolysin of was used in this study because it has an essential role in infections and because emodin shares structural features with compounds that target this enzyme.

Phytochemical Characterization, In Vitro Anti-Inflammatory, Anti-Diabetic, and Cytotoxic Activities of the Edible Aromatic Plant; .

is a medicinal herb that alleviates inflammations and fever. Chromatographic separation, phytochemical characterization, and in vitro biological activities of the plant -hexane extract were conducted for the first time in this study. Six compounds were isolated for the first time from the -hexane fraction of aerial parts and were identified on the bases of NMR and MS analyses as pseudo-taraxaterol (), pseudo-taraxasterol acetate (), 3β-acetoxytaraxaster-20-en-30-aldehyde (), calenduladiol-3--palmitate (), stigmasterol (), and α-tocospiro B ().

New phytoconstituents, anti-microbial and cytotoxic activities of Schweinf.

is wild plant growing in the desert of Egypt, and it has folkloric medicinal uses. Phytochemical investigation of extracts led to the isolation and identification of seven compounds. Among these compounds are three new simple phenolics: Resacetophenone-6-methyl [], Resorcinol [], Resorcinol-O- β -Glucoside []; phenolic ester; and other four known compounds: Methylparaben [4]; two chromones, Noreugenin [], Eugenin []; and one cyclitol: pinitol [].
