Introduction: Gallic acid (GA), a phenolic molecule that occurs naturally, has been shown to have anti-tumor properties for a number of cancer types. The effect of GA on breast tumor cells MDA-MB-231 Triple Negative was examine in the current study. Methods: Techniques were utilised for cell cycle analysis, GSH concentration, Annexin V assay, light and fluorescence microscopy, restriction of cell growth (MTT assay), preparation, characterisation, and measurement of the mitochondrial membrane potential. Results: It was shown that the produced GANP significantly reduced the ability of MDAMB-231 cells to multiply. Moreover, this might result in glutathione depletion, an increase in ROS levels, and cytotoxic activity in MDA-MB-231 cells. Analysis using flow cytometry revealed so as to the GANP enhanced the inhabitants of sub-G1 cells. Also, the Annexin V/PI test and fluorescence labelling both established so as to the addition of GA dramatically increased the amount of apoptotic cells. Therefore, research of the oxidative damage-related sickness revealed that the amalgamation of GA greatly decrease oxidative damage in healthy cells while increasing glutathione levels and lowering lipid peroxidase levels in MDA-MB-231 cells Conclusion: These consequences propose that GA as GANP may have potential as a chemopreventive treatment for triple negative breast cancer.

BACKGROUNDBotryosphaeria dieback is a canker disease caused by fungal species of the Botryosphaeriaceae family that threatens almond productivity. The most common control measure to prevent canker development is the application of fungicides which are being phased out by European Union regulations. In the present study, two sets of bacterial strains were evaluated for their antifungal activity against pathogenic Botryosphaeriaceae species through in vitro and in vivo antagonism assays.RESULTSThe rhizospheric bacteria Pseudomonas aeruginosa AC17 and Bacillus velezensis ACH16, as well as the endophytic bacteria Bacillus mobilis Sol 1–2, respectively inhibited 87, 95, and 63% of the mycelial growth of Neofusicoccum parvum, Botryosphaeria dothidea, Diplodia seriata, and Macrophomina phaseolina. Additionally, they significantly reduced the length of lesions caused by N. parvum and B. dothidea in artificially inoculated detached almond twigs. All these bacterial strains produce hydrolytic enzymes that are able to degrade the fungal cell wall. P. aeruginosa AC17 also produces toxic volatile compounds, such as hydrogen cyanide. This strain was the most effective in controlling Botryosphaeria dieback in planta under controlled conditions at a level similar to the biocontrol agent Trichoderma atroviride and standard chemical fungicide treatments.CONCLUSIONPseudomonas aeruginosa AC17 is the best candidate to be considered as a potential biocontrol agent against Botryosphaeriaceae fungi affecting almond. © 2023 Society of Chemical Industry.

BACKGROUNDIn the perpetual struggle to manage mosquito populations, there has been increasing demand for the development of biopesticides to supplant/complement current products. The insecticidal potential of Xenorhabdus and Photorhabdus has long been recognized and is of interest for the control of important mosquitoes like Aedes albopictus which vectors over 20 different arboviruses of global public health concern.RESULTSThe larvicidal effects of cell‐free supernatants, cell growth cultures and cell mass of an extensive list of Xenorhabdus and Photorhabdus spp. was investigated. They were quite effective against Ae. albopictus causing larval mortality ranging between 52–100%. Three Photorhabdus spp. and 13 Xenorhabdus spp. release larvicidal compounds in cell‐free supernatants. Cell growth culture of all tested species exhibited larvicidal activity, except for Xenorhabdus sp. TS4. Twenty‐one Xenorhabdus and Photorhabdus bacterial cells (pellet) exhibited oral toxicity (59–91%) against exposed larvae. The effect of bacterial supernatants on the mosquito eggs were also assessed. Bacterial supernatants inhibited the hatching of mosquito eggs; when unhatched eggs were transferred to clean water, they all hatched. Using the easyPACId approach, the larvicidal compounds in bacterial supernatant were identified as fabclavine from X. szentirmaii and xencoumacin from X. nematophila (causing 98 and 70% mortality, respectively, after 48 h). Xenorhabdus cabanillasii and X. hominickii fabclavines were as effective as commercial Bacillus thuringiensis subsp. israelensis and spinosad products within 5 days post‐application (dpa).CONCLUSIONFabclavine and xenocoumacin can be developed into novel biolarvicides, can be used as a model to synthesize other compounds or/and can be combined with other commercial biolarvicides.This article is protected by copyright.
