Mesoporous silica nanoparticles (MSNs) have been used as an anticancer drug delivery system with high safety and entrapment capacity thanks to their large internal space for drug accommodation, durable structure, and good biocompatibility. However, the treatment efficiency of the bare MSNs is limited due to its drug leakage and burst release. In this study, a phospholipid bilayer was covered on the MSNs surface (MSN@Lip) as a liposomal cap that not only reduced drug leakage but also improved the stability of the colloidal system.

. In vitro biological evaluation revealed the most active compound 4d with an inhibitory concentration of 42.87 μM against K562 and 47.42 μM on A549 cells. The anticancer activity of this naphthylidene isoxazolidinedione derivative was evident by cell cycle and apoptosis assays, which showed arrest of the G2/M phase (65.6%) of the K562 cells and induction of apoptosis with 21.47% apoptotic cells as compared to 0.2% of untreated cells, respectively.

The present study investigated the phytochemical and biological properties of the rhizomes C. aromatica. From the CHCl3 extract of C. aromatic rhizomes, six known compounds, including (-)-hannokinol, (3R,5R)-3,5-diacetoxy-1,7-bis(4- hydroxyphenyl)heptane, naringenin, 2-(4- (hydroxymethyl)phenyl)propan-2-ol, 5-hydroxymethylfurfural, and bisacurone, were isolated. All compounds were tested on the biological inhibitory activities against tyrosinase, αglucosidase, and urease. It was the first time all compounds were isolated from rhizomes of C. aromatica Salisb.

Usnic acid isolated from lichen was a potential bioactivity compound. It has a broad spectrum bioactivity, including antiviral, anti-inflammatory, anticancer… However, low solubility in water limited its application. Many researchs have done to overcome the restriction. Recent results showed that usnic acid derivatives bearing triazole, enamine, pyrazole and benzylidene groups had strong antiviral and anticancer activities. Thus, investigation of usnic acid derivatives synthesis was an attractive aspect due to the diversity of bioactivities of usnic acid derivatives.

Three fungal metabolites, (1) O-methylsilvaticol, (2) orthosporin and (3) diplosporin were isolated from a rare fungus, Kretzschmaria sandvicensis, collected in Dien Bien, in northwest Vietnam. Their structures were established using a combination of high resolution MS (FT-ICR-MS) and 1H-NMR, 13C-NMR, HSQC and HMBC spectroscopy. They were evaluated for anticancer properties against the KB cell line.

Nuclear factor erythroid-2 related factor 2 (Nrf2) is a crucial transcription factor that regulates the expression of defensive antioxidants and detoxification enzymes in cells. In a previous study, we showed that expression of the Nrf2 gene is regulated by an epigenetic modification. Rauvolfia verticillata, a traditional Chinese herbal medicine widely used in China, possesses anticancer and antioxidant effects. In this study, we investigated how Nrf2 is epigenetically regulated by reserpine, the main active component in R. verticillata, in mouse skin epidermal JB6 P+ cells.
