Structural analogs of PFI-1 varying at the sulfur core were prepared, and their activities as BET inhibitors in myeloid cell lines and primary cells from patients with acute myeloid leukemia were studied. Docking calculations followed by mol. dynamics simulations revealed the binding mode of the newly prepared inhibitors, suggesting explanations for the observed high enantiospecificity of the inhibitory activity.

Reactive oxygen species (ROS) depletion and low ROS production that result from the intratumoral redox metabolism equilibrium and low energy conversion efficiency from ultrasound mech. energy to ROS-represented chem. energy, resp., are two vital inhibitory factors of sonodynamic therapy (SDT). To address the two concerns, a tumor metabolism-engineered composite nanoplatform capable of intervening intratumoral ROS metabolism, breaking the redox equilibrium, and reshaping the tumor microenvironment is constructed to reinforce SDT against tumors. In this metabolism-engineered nanoplatform, Nb2C nanosheets serve as the scaffold to accommodate TiO2 sonosensitizers and L-buthionine-sulfoximine. Systematic experiments show that such nanoplatforms can reduce ROS depletion via suppressing glutathione synthesis and simultaneously improving ROS production via the Nb2C-enhanced production and separation of electron-hole pairs. Contributed by the combined effect, net ROS content can be significantly elevated, which results in the highly efficient anti-tumor outcomes in vivo and in vitro. Moreover, the combined design principles, i.e., tumor metabolism modulation for reducing ROS depletion and electron-hole pair separation for facilitating ROS production, can be extended to other ROS-dependent therapeutic systems.

Origanum compactum is a medicinal species endemic to Morocco and highly exploited for its therapeutic properties. In the present study, we examined the chem. composition and biol. activities of the essential oils from wild and cultivated O. compactum. The chem. composition was analyzed by gas chromatog. coupled with mass spectrometry (GC/MS). The yield of essential oils was 3.5% for the wild plants and 3.4% for the cultivated plants. Twelve compounds have been identified in the essential oils of wild plants. Carvacrol was the predominant compound (59.0%), followed by p-cymene (18.4%) and then by ¦Ã-terpinene (8.4%). For the cultivated plants, 27 compounds were identified. Here again, carvacrol was the predominant compound (45.3%), followed by p-cymene (22.2%) and by ¦Ã-terpinene (10.1%). The antifungal activity of essential oils was evaluated against four Candida strains using the aromatogram method, the min. inhibitory concentration (MIC) and the min. fungicidal concentration (MFC). In semi-solid medium, essential oils were active against all the strains tested. In liquid medium, MIC values ranged from 216 to 234¦Ìg/mL, while the MFC was 288¦Ìg/mL. Antioxidant activity was investigated by 2,2-diphenyl-1,1,picrylhydrazil radical (DPPH) and the findings showed that the essential oils of both plants have a good antioxidant effect. In conclusion, domestication is a practical approach to preserve O. compactum from extinction without compromising its biol. activities. Besides, the essential oils of O. compactum could be a promising and sustainable alternative to replace the synthetic compounds used currently in pharmaceutical and food industries.

Plant-based phytotoxins play an important role in plant-plant interaction and are of great promise for the development of bioherbicide. In this study, screening of essential oils from six different Curcuma rhizomes identified black turmeric (Curcuma caesia Roxb.) oil as an efficient growth inhibitor in wheatgrass coleoptile bioassay (IC50 57.1¦Ìg/mL). The phytotoxic efficacy of this oil was further confirmed through the dose dependent (10.0-300.0¦Ìg/mL) inhibition of germination, coleoptile and radicle growth of wheatgrass seeds in water medium (IC50 176.7, 90.6 and 93.0¦Ìg/mL resp.) and the pre-germinated seeds in agar medium. Activity-guided fractionation and purification of the crude oil identified curzerenone, a major furanosesquiterpene in this oil as the most active phytotoxin (IC50 13.0¦Ìg/mL in coleoptile bioassay; 188.3, 34.7 and 36.7¦Ìg/mL resp. in water medium). Structure-activity relationship study indicated the importance of all the functional groups for its phytotoxicity. A significant contribution by the oxygenated monoterpenes towards oil phytotoxicity was also evidenced. Though inhibitory efficacy of the oil was comparatively weak in soil, a profound activity through aerial diffusion was observed against germination and/or growth of fresh and pre-germinated wheatgrass seeds (IC50 1.4-6.2 mg/L air). The study also confirmed the uptake of active phytotoxins with no detectable transformation by the seeds in water and their persistence in the soil for at least one and half months. Further, its applicability was demonstrated through an efficient post-emergence growth inhibition (IC50 37.0-81.4¦Ìg/mL) of bermudagrass weed in water and agar medium.

Summary : To find an innovative use for orange peels discarded in the orange juice-making process, a fermentative process was assessed using a Lactiplantibacillus plantarum strain. Blanched or rinsed peels were submerged in a 5% NaCl-3% inoculated sucrose brine for 10 days. Total soluble solids, pH, sugars and total aerobic and anaerobic counts were determined in the brines to characterize the process. The final products were characterised by instrumental texture, color and volatile composition The blanching pretreatment had a significant effect on the whole process and the final product characteristics. Anaerobic bacteria total counts were significantly higher in the blanched samples during the whole fermentation, and pH decreased significantly slower in these samples than in the rinsed ones. Rinsed samples were characterised by higher aerobic total counts, higher sucrose consumption and higher glucose, fructose and polyalcs. production The texture was softer in the pretreated samples, probably due to the blanching process rather than the fermentation The volatile composition was quite similar between samples, although it was different from one of the raw orange peels due to a significant decrease in various volatile compounds
