In the present investigation, aqueous, ethanol and petroleum ether, ethanol (1:1) root extracts of Seidenfia rheedii were tested against 12 different human pathogenic bacteria for antibacterial activity. It was found that ethanolic extracts inhibited the growth of all the bacterial strains tested whereas moderate antibacterial activity was associated with petroleum ether, ethanol (1:1) root extracts. The aqueous extract did not show antibacterial activity. Thus the present investigation reveals that the selected plant extracts have potential of bactericidal effect on test bacteria.

Candida is a commensal fungus of clinical interest that commonly lives in oral cavity and intestine but can become an opportunist microrganism and cause severe infections. A serie of 10 aminochalcones were designed and synthetized to obtain compounds anti-Candida with potent and broad-spectrum activity. The most active compound J34 demonstrated excellent in vitro activity against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata and Candida krusei with minimum inhibitory concentration between 1.

Piperazine-based compounds have garnered significant attention due to their notable biological and pharmacological activities, making them essential in fine chemical and pharmaceutical applications. In this study, we managed to synthesize a novel hybrid bis-cyanoacrylamide bearing the piperazine core via phenoxymethyl linker and incorporating sulphamethoxazole moiety. The novel compound was fully characterized using different spectral data including 1H-NMR, C-NMR, and FTIR spectroscopy.

Bacterial infections can lead to severe medical complications, including major medical incidents and even death, posing a significant challenge in clinical trauma repair. Consequently, the development of new, efficient, and non-resistant antimicrobial agents has become a priority for medical practitioners. In this study, a stepwise hydrothermal reaction strategy is utilized to prepare FeO@MoS core-shell nanoparticles (NPs) with photosynthesis-like activity for the treatment of bacterial infections.

Infectious diabetic wounds pose an arduous threat to contemporary healthcare. The combination of refractory biofilms, persistent inflammation, and retarded angiogenesis can procure non-unions and life-threatening complications, calling for advanced therapeutics potent to orchestrate anti-infective effectiveness, benign biocompatibility, pro-reparative immunomodulation, and angiogenic regeneration. Herein, embracing the emergent "living bacterial therapy" paradigm, a designer probiotic-in-hydrogel wound dressing platform is demonstrated.
