Parmoferone A, a new depsidone from the lichen .

A new depsidone, parmoferone A (), together with three known compounds, parmosidone K (), albifolione (), and 4-chloroorcinol () were isolated from the lichen (Taylor) Hale (Parmeliaceae). The structures of isolated compounds were identified from its spectroscopic data and by comparison with the literature. Compounds were evaluated for alpha-glucosidase inhibition.

Recurvataside, a new saponin from aerial parts of .

A new glycoside, recurvataside () and six known compounds, quinovic acid (), quinovic acid 28---D-glucopyranosyl ester (), 3---D-glucopyranosylquinovic acid (), 3---D-glucopyranosylquinovic acid 28---D-glucopyranosyl ester (), pomolic acid (), and ursolic acid () were isolated from aerial parts of . The structure of compound was identified from its spectroscopic data and by comparison with the literature. Recurvataside represents the first occurrence of -oleanolic acid saponin bearing two D-glucose units at C-3 and C-28 in nature.

Synthesis, Docking Study, Cytotoxicity, Antioxidant, and Anti-microbial Activities of Novel 2,4-Disubstituted Thiazoles Based on Phenothiazine.

Unlabelled: A series of novel 1,3-thiazole derivatives (5a-i) with a modified phenothiazine moiety were synthesized and tested against cancer cell line MCF-7 for their cytotoxicity. Most of them (5a-i) were less cytotoxic or had no activity against MCF-7 cancer cell line.

Material And Methods: The IC50 value of compound (4) was 33.

Cytotoxic activity and phytochemical composition of V.S. Dang leaves.

For the first time, the cytotoxic and phytochemical investigation of the leaves of V.S. Dang, a new species discovered in Viet Nam were finalized and led to purify nine compounds, including one furancoumarin , one chromone , two triterpenoids , two flavonoids , , two flavanoids and one iridoid using various chromatography methods.

Green synthesis of silver nanoparticles using Nelumbo nucifera seed extract and its antibacterial activity.

Silver nanoparticles (AgNPs) were synthesized using a Nelumbo nucifera dry seed extract, which is a simple, non-toxic, eco-friendly "green material". The synthesized nanoparticles were confirmed by the color changes and characterized by UV-visible spectroscopy. The AgNPs were stable at room temperature for 2 months.
