Five new metabolites, including three cyclic dipeptide derivatives (-) and two new polyketides (-), together with nine known ones (- and -), were isolated from the mangrove-sediments-derived fungus sp. SCSIO 41431. Their structures were determined using detailed NMR, MS spectroscopic analyses, and quantum chemical calculations.

Fourier-transform infrared spectroscopy (FTIR) serves as a rapid analytical technique to characterize food specimens chemically. The purpose of this study was to investigate the potential of FTIR combined with multivariate statistics to detect Alpha-glucosidase (Alpha-glu) inhibitory activities of a non-cereal flour-like coconut testa flour (CTF). CTF of five distinct local cultivars was sequentially extracted with hexane, ethyl acetate (EtOAc), and methanol (MeOH) to assay the Alpha-glu inhibitory activity.

Article Synopsis
  • - The study explores the use of CdS nanorods modified with a catalyst to efficiently generate the nicotinamide cofactor 1,4-NADH, which is essential for energy transfer in biological systems and could enhance photosynthetic biohybrid systems.
  • - The semiconductor nanocrystal model system achieves high turnover frequency (TOF) for NADH production, making it one of the most efficient inorganic photosensitizer applications reported so far.
  • - Understanding the charge transfer kinetics in this setup, which ranges from 10 to 10 seconds, is crucial for improving solar energy conversion and developing systems that replicate natural photosynthesis for sustainable chemical production.
