Summary: The synthesis of tertiary phosphines(III) has been a long-standing challenge in synthetic chemistry due to issues including harsh conditions, sensitive organometallic reagents, and pre-functionalized substrates. In this study, a strategically novel C(sp(3))-H bond phosphorylation method is reported, which allows for the synthesis of structurally diverse tertiary phosphines(III) from industrial phosphine(III) sources under mild photocatalytic conditions. The combination of ligand-to-metal charge transfer (LMCT) and hydrogen atom-transfer (HAT) process enables the generation of alkyl radicals from hydrocarbons. Furthermore, this catalytic system can also be applied for the polymerization of electron-deficient alkenes.

Summary: Crystalline Pd7P3 and Pd3P0.8 nanoparticles were obtained by thermolysis of palladium(II)-complexes of two different ligands. These nanoparticles showed lower catalytic activity than the parent complexes in Suzuki-Miyaura coupling reactions. The catalysis involved the formation of Pd-NPs associated with ligands or their fragments. Three phase tests revealed that both the complexes and the nanoparticles had both homogeneous and heterogeneous catalytic processes.

Summary: Structural units containing imidazole motif are crucial in many functional and biologically active molecules. The arylation of C-H bond with a high degree of regioselectivity is an effective approach for derivatizing imidazole. The C-4 carbon in imidazole is the least preferred site for C-H arylation reaction, while the C-2 and C-4 carbon centers are highly susceptible.

Summary: The aim of this study was to determine the optimum condition for preparing chitooligosaccharide-catechin conjugate (COS-CAT) liposomes using different stabilising agents. COS-CAT liposomes were prepared using soy phosphatidylcholine (SPC) and either glycerol or cholesterol, and their encapsulation efficiency, loading capacity, physicochemical characteristics, FTIR spectra, thermal stability, and structure were assessed. The results showed that COS-CAT loaded liposome stabilised by cholesterol (COS-CAT-CHO) exhibited higher stability, with the highest encapsulation efficiency and loading capacity, and the lowest zeta potential, polydispersity index, and releasing efficiency.

Summary: Enrichment of n-3 polyunsaturated fatty acids (PUFA) in skipjack tuna eyeballs oil (STEO) was investigated using lipases from different yeast strains. Among all lipases tested, Candida rugosa extracellular lipase (Cr-ECL) showed promising enrichment of EPA and DHA in STEO. RSM was used to optimize reaction conditions and resulted in a significant increase in DHA and EPA concentration in STEO. The established hydrolysis protocol successfully converted fish oil from tuna waste to valuable fish oil enriched with n-3 fatty acids.

Summary: The gelling behaviors of partially purified myofibrillar proteins (PPMP) extracted from Indian mackerel (IM) and threadfin bream (TB) were compared at different heating temperatures. The results demonstrated that IM-MP exhibited lower turbidity, surface hydrophobicity, and disulfide bond content compared to TB-MP. The amino acid profile showed no significant difference between the two species, except for lysine and glutamine. Structural analysis confirmed these differences, and the transmission analysis revealed lower aggregation and crosslinking ability of IM-MP. Therefore, the gelling behavior of IM-MP was poorer compared to TB-MP.

Summary: The inhibitory effects of chitooligosaccharide (CHOS) conjugates, including CHOS-catechin (CHOS-CAT), CHOS-epigallocatechin gallate (CHOS-EGCG), and CHOS-gallic acid (CHOS-GAL), on Pacific white shrimp cephalothorax polyphenoloxidase (PPO) were studied. CHOS-CAT showed the strongest inhibitory activity against PPO and exhibited mixed-type inhibition. Molecular docking analysis revealed that CHOS-CAT interacts with various amino acid residues near the active site of PPO. Therefore, CHOS-CAT could serve as an anti-melanosis agent to prevent discoloration in crustaceans.

Summary: The effects of epigallocatechin gallate (EGCG) at 200 or 400 ppm on the quality changes of cooked Harpiosquillid mantis shrimp (Harpiosquilla raphidea) (CHMS) meat subjected to varying freeze-thaw cycles (F-T-C; 0, 1, 3, and 5) were studied. With increasing F-T-C, the CHMS meat deteriorated to a higher extent, indicated by increased exudate loss, tougher texture, and higher microbial counts. The addition of EGCG could dose-dependently retard these changes, as well as prevent microbial growth and lipid oxidation. The alterations in disulfide bond content and surface hydrophobicity of CHMS added with EGCG were more pronounced with higher EGCG concentration.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
