Two ternary copper(II) complexes with 2,2-biquinoline (BQ) and with sulfonamides: sulfamethazine (SMT) or sulfaquinoxaline (SDQ) whose formulas are Cu(SMT)(BQ)Cl and Cu(SDQ)(BQ)Cl¡¤CH3OH, in what follows SMTCu and SDQCu, resp., induced oxidative stress by increasing ROS level from 1.0 ¦ÌM and the reduction potential of the couple GSSG/GSH2. The co-treatment with L-buthionine sulfoximine (BSO), which inhibits the production of GSH, enhanced the effect of copper complexes on tumor cell viability and on oxidative damage. Both complexes generated DNA strand breaks given by-at least partially-the oxidation of pyrimidine bases, which caused the arrest of the cell cycle in the G2/M phase. These phenomena triggered processes of apoptosis proven by activation of caspase 3 and externalization of phosphatidylserine and loss of cell integrity from 1.0 ¦ÌM. The combination with BSO induced a marked increase in the apoptotic population. On the other hand, an improved cell proliferation effect was observed when combining SDQCu with a radiation dose of 2 Gy from 1.0 ¦ÌM or with 6 Gy from 1.5 ¦ÌM. Finally, studies in multicellular spheroids demonstrated that even though copper(II) complexes did not inhibit cell invasion in collagen gels up to 48 h of treatment at the higher concentrations, multicellular resistance outperformed several drugs currently used in cancer treatment. Overall, our results reveal an antitumor effect of both complexes in monolayer and multicellular spheroids and an improvement with the addition of BSO. However, only SDQCu was the best adjuvant of ionizing radiation treatment.

The herbal tea made from the leaves and stems of Cyclocarya paliurus is thought to be more flavorful than those made from the leaves only. However, evidence supporting this view is not available yet. 53 VOCs and 54 non-VOCs were identified via HS-SPME-GC-MS and UPLC-Q-TOF/MS, resp., which were found to vary dramatically in three groups of samples (combination of stems and leaves, separated leaves, and separated stems). 11 VOCs and 18 non-VOCs potential markers are responsible for the change of metabolic effects through the biosynthesis of flavonoids, the synthesis of terpenoids, and the oxidation of fatty acids and carotenoids. In response, the stems were effective to enhance fatty odors, the initial astringency and bitterness and the aftertaste of sweetness of the leaves. Stems are conducive to increasing total phenolic content, total flavonoid content and antioxidant capacity of Cyclocarya paliurus herbal extract because of the increase in polyphenols. In addition, the stems have the potential to be used as raw materials for nerolidol and polyphenols extraction This study has been the first to determine the contribution of stem to the flavor of Cyclocarya paliurus herbal tea and these results provide the theor. basis for making Cyclocarya paliurus herbal tea with stems.

In this research using Zedo gum (ZG) and CM-cellulose (CMC) as well as Lemon and Ferulago extracts (LVE/FAE) new active packaging was designed. Biodegradable films with five various proportions of ZG to CMC were made by applying the casting process. The incorporation of LVE or FAE into CMC/ZG composite films significantly reduced moisture content (MC) and water vapor permeability (WVP). The tensile strength increased from 6.92 (MPa) for CMC/ZG film to 11.51 MPa for CMC/ZG/2.5¦Ìl LVE and FAE film; as well as elongation at break decreased from 24.21% for CMC/ZG film to 6.10% for CMC/ZG/2.5¦Ìl LVE and FAE film. In conclusion, the 20:80 proportion of ZG/CMC along with 2.5¦Ìl LVE and FAE can be used as the best ratio for mech. properties, moisture content, and permeability compared to the CMC/ZG film with individual FAE or LVE and can be a good source for making edible films.

Mosquitoes are well-known vectors of malaria, dengue fever, chikungunya, yellow fever, Zika and many other diseases, and have become a great threat to public health. Nowadays, chem. insecticides are widely used for the control of mosquitoes. However, their widespread use has created some serious problems, such as insecticide resistance, environmental pollution, and toxicity to human beings. With the objectives to develop novel botanical and eco-friendly insecticides for mosquitoes, in this study we examined the chem. compositions of the essential oils (EOs) from different aging years of Pericarpium Citri Reticulatae (PCR, Guangchenpi in Chinese), and investigated their anti-mosquito activity in details. As a result, 39, 44, 48, and 40 main components were identified from the 1-, 5-, 10-, and 15-yr PCR EOs, resp. For each PCR EO, D-limonene (47.90-56.39%) and ¦Ã-terpinene (14.98-17.03%) were the major components. These PCR EOs showed potent larvicidal activity against Aedes albopictus (A. albopictus) larvae (LC50 = 54.50-68.23 ppm ppm), and some of the major components were also very active, including D-limonene (LC50 = 56.17 ppm), ¦Ã-terpinene (LC50 = 64.28 ppm), ¦Â-myrcene (LC50 = 54.51 ppm) and terpinolene (LC50 = 57.69 ppm). These PCR EOs exhibited similar larvicidal activity, and their insecticidal activity may be attributed to the major constituents such as D-limonene, ¦Ã-terpinene and terpinolene. In addition, thymol was found more effective against A. albopictus adults (LC50 = 96.82 ppm) than the other components, such as Me 2-(methylamino) benzoate (LC50 = 382.10 ppm) and ¦Á-terpineol (LC50 = 507.54 ppm), and this compound could be one of the active components responsible for the adulticidal activity. Enzyme inhibition assays suggested that the activity of acetylcholinesterase, mixed function oxidase and esterase were significantly inhibited, which may result in the mortality of A. albopictus larvae. The present findings clearly demonstrated that naturally-occurring PCR EOs and the functional components display potent insecticidal activity against A. albopictus larvae and adults, and therefore, strongly suggest that PCR EOs and the main components are exploitable as botanical insecticides for the control of mosquitoes.
