Chemical constituents and bioactivities of Blumea balsamifera (Sembung): a systematic review

Molecular Structure, Antioxidant Potential, and Pharmacokinetic Properties of Plant Flavonoid Blumeatin and Investigating Its Inhibition Mechanism on Xanthine Oxidase for Hyperuricemia by Molecular Modeling

“…According to Table , eight conventional hydrogen bonds formed between Thr1010 (CO and O–H), Val1011 (CO), Arg880 (O–H), Phe914 (O–H), and Ala1078 (O–H) are 2.70, 3.26, 2.93, 2.97, 3.08, 2.03, 4.04, and 3.58 Å, respectively. Strong (almost covalent), moderate (mostly electrostatic), and weak electrostatic hydrogen bonds refer to the distances between 2.2 and 2.5, 2.5–3.2, and 3.2–4.0 Å, respectively. , Based on these definitions, blumeatin binds to XO with very strong (almost covalent) bonds (2.03 Å) via Arg880, moderate hydrogen bonds (2.70, 2.93, and 2.97 Å) via Thr1010, and weak hydrogen bonds (3.26, 3.08, 4.04, and 3.58 Å) via Thr1010, Val1011, Phe914, and Ala1078, respectively. Finally, the rest of the residues in XO surrounding blumeatin formed hydrophobic interactions via Glu802, Asn768, Ser1008, Glu1261, Phe1013, Phe1150, Ser876, Lys771, and Thr803 (mainly van der Waals and hydrophobic).…”

“…In their study, Hadi and Nastiti also demonstrated that blumeatin interacted with Tyr, Leu, Asn, and Cys residues . Another study focused on a detailed review on selected particular flavonoids including blumeatin and their chemical constituents, and bioactivities were evaluated, but their study did not give any detailed information on blumeatin . On the other hand, two selected flavonoids (blumeatin and luteolin) were also docked against caspase-1 by optimizing these two ligands by semiempiric optimization method (AM1), and it was considered that blumeatin and luteolin were suggested to be anti-inflammatory agents .…”

Surface plasmonic biosensors: principles, designs and applications

“…In 2023, Tan et al proposed a universal SPR sensor capable of detecting environmental contaminants in water, using nucleic acids, antibodies and receptors as specific recognition molecules. 73 Common toxic metal ions, biotoxins, and endocrine disruptors in the environment are monitored (Fig. 4c).…”

Treatment of MB wastewater with a Fe–RGO/TiO2/PTFE photocatalytic composite membrane

“…7 Appropriate metal ion doping improves crystal integrity, inhibits crystal growth, and broadens the light absorption band of TiO 2 . 8 Choi et al investigated the photocatalytic effect of TiO 2 doped with Fe 3+ , Mo 3+ , Ru 3+ , Os 3+ , Re 3+ , V 4+ , and Rh 3+ , and found that doping with all these metal ions effectively enhanced the photocatalytic activity of TiO 2 . Notably, Fe 3+ doping, with its half-filled d electron configuration and a similar ionic radius to Ti 4+ , proved particularly effective.…”
