scopolin/悪性腫瘍

Cytotoxic effect of five known compounds, khellin, berberine, lupeol, scopolin, rapanone, obtained from Colombian plants, were determined against human tumor cell lines as an indicator of the potential anticancer activity of these compounds. Berberine and rapanone presented interesting cytotoxicity.

The high expression of fatty acid synthase (FAS) in tumor cells is consistent with their elevated requirement for fatty acids for cell membrane synthesis and energy supply to support their almost unlimited proliferation. The expression levels of FAS in tumor cells are related to their proliferation,

In this work, LC-ESI-TOF-MS and GC-EI-MS were used to assess the potential of Artemisia herba alba as a source of health-promoting constituents. Besides, the antioxidant, the antimicrobial and the cytotoxic potentials were evaluated. A total of 86 metabolites, including C-glycosylated and methylated

OBJECTIVE To investigate the chemical and bioactive constituents from the stems and leaves of Micromelum integerrimum. METHODS The chemical constituents were isolated and purified by silica gel, Sephadex LH-20, and HPLC. Their structures were mainly elucidated on the basis of extensive 1D- and

Continued chemical investigation on the fruits of North American Aesculus pavia L. resulted in the isolation and identification of 13 polyhydroxyoleanene pentacyclic triterpenoid saponins, named aesculiosides IIe-IIk (1-7), and IIIa-IIIf (8-13), together with 18 known compounds: aesculiosides Ia-Ie

Carbonic anhydrase IX (hCAIX) is a membrane-spanning metalloenzyme, encoded by CA9 gene, which can lead to various carcinomas if upregulated. Due to its overexpression in many cancer tissues, hCAIX has become a promising target for developing anticancer therapeutics. Furthermore, several
