The 70% ethanolic extracts from eight neglected fruits; , , , , , , and were evaluated for their 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, α-glucosidase inhibitory activities as well as total phenolic content. The results of this study revealed that fruit extract demonstrated the most potent radical scavenging activity. Among the fruits examined for α-glucosidase inhibitory activity, and exhibited strong activity with no significant difference. The Pearson correlation indicated that the activities of and contributed by phenolic compounds. A total of 65 metabolites were tentatively identified by using ultra-high-performance liquid chromatography tandem mass spectrometry (UHLPC-MS/MS). These findings suggested that the possible application of and as a functional food with antioxidant and α-glucosidase inhibitory properties.

The development of new medicines with unique methods of antimicrobial action is desperately needed due to the emerging multidrug-resistant bacteria, such as methicillin-resistant Staphylococcus aureus. Therefore, antimicrobial peptoids have emerged as potential new antimicrobials. Thirteen peptoid analogues have been designed and synthesized via solid phase synthesis.

Fifteen novel carbazole alkaloids, euchrestifolines A-O (1-15), were obtained from Murraya euchrestifolia. Their structures were elucidated by spectroscopic analysis, Mosher's ester, calculated ECD, and transition metal complex ECD methods. Notably, euchrestifolines A-C (1-3) are the first naturally occurring pyrrolidone carbazoles to be identified, while euchrestifolines D-F (4-6) represent rare carbazole alkaloids containing a phenylpropanyl moiety; euchrestifoline G (7) features a unique benzopyranocarbazole skeleton.

Unlabelled: The performance of the Liofilchem Compact Antimicrobial Susceptibility Panel (ComASP) Cefiderocol was evaluated in a multicenter study. Enterobacterales, , and clinical isolates and challenge isolates were tested by three and one sites, respectively. Minimum inhibitory concentration (MIC) testing was performed by the Clinical and Laboratory Standards Institute (CLSI) broth microdilution and ComASP, which included two reading endpoints (CLSI read; MIC is the first well in which reduction of growth is <1 mm or light haze/faint turbidity] and ComASP [ComASP read; MIC is the first well at which 100% inhibition of growth occurs]).

Determination of antimicrobial resistance (AMR) in pneumococcal isolates is important for surveillance purposes and in a clinical context. Antimicrobial susceptibility testing (AST) of pneumococci is complicated by the need for exact minimal inhibitory concentrations (MICs) of beta-lactam antibiotics. Two next-generation sequencing (NGS) analysis tools have implemented the prediction of AMR in their analysis workflow, including the prediction of MICs: Pathogenwatch (https://pathogen.

Brucellosis has therapeutic challenges due to 3%-15% relapses/therapeutic failures (R/TF) after antibiotic treatment. Therefore, determining the antibiotic concentration in tissues, the physiopathological parameters, and the R/TF after treatment is relevant. After exploring different antibiotic quantities, we found that a combined dose of 100 µg/g of doxycycline (for 45 days) and 7.
