Computational Design, Synthesis, and Biological Assessment of Some Pyrrolo[3,4‐c]Pyrroles Targeting Mycobacterium Tuberculosis

open access: yesChemistrySelect, Volume 10, Issue 17, May 5, 2025.
A new set of spirooxindole‐ and spiroindenoquinoxaline‐derived pyrrolo[3,4‐c] pyrroles has been synthesized through atom‐economic one‐pot multicomponent reactions. Based on the results, compounds 4b and 5a demonstrated promising Glide scores and exhibited strong binding affinity with decaprenylphosphoryl‐β‐D‐ribofuranose oxidoreductase.

Lycium‐Barbarum Polysaccharide‐Loaded Dual‐Crosslinked Rigid Hydrogel Enhances Bone Healing in Diabetic Bone Defects by Scavenging Reactive Oxygen Species

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 11, April 25, 2025.
A novel hydrogel (HLBP) incorporating natural polysaccharides from goji berries is developed to enhance diabetic bone defect healing. The hydrogel efficiently scavenges ROS, improves osteogenic differentiation, and promotes in vivo bone regeneration. This strategy offers a biocompatible and localized approach, overcoming the challenges of traditional ...

3‐D Sustained‐Release Culture Carrier Alleviates Rat Intervertebral Disc Degeneration by Targeting STING in Transplanted Skeletal Stem Cells

open access: yesAdvanced Science, Volume 12, Issue 15, April 17, 2025.
Schematic representation of mechanisms by which the 3‐D sustained‐release culture carrier prevents accumulation of ROS by continuously releasing C‐176@PDA‐NPs and inhibiting the cGAS‐STING activated by sudden hypoxia, thereby preventing ferroptosis and promoting differentiation in SSCs and ultimately attenuating IVDD progression.

Bio‐inspired Catalyst‐Modified Photocathode for Bias‐Free Photoelectrochemical NADH Regeneration

open access: yesAdvanced Science, Volume 12, Issue 8, February 24, 2025.
Inspired by the structure and function of the thylakoid membrane and electron transport mediator function of Ferredoxin, a catalyst‐immobilized photocathode is constructed by self‐assembly of the aliphatic chain substituted [Rh(Cp*)(bpy)] molecules (Rh‐vi2+) and aliphatic chain decorated polythiophene semiconductors (PTTH), which can be coupled with a ...

Enzymatic and Enzyme‐Free Electrochemical Lactate Sensors: A Review of the Recent Developments

open access: yesElectrochemical Science Advances, Volume 5, Issue 1, February 2025.
ABSTRACT Lactate is a useful analytical indicator in various fields. The lactate monitoring benefits from evaluating the body's condition, as excessive muscle use or fatigue can result in injury. Further, it is useful for alerting to emergencies like haemorrhage, hypoxia, respiratory distress, and sepsis.

Star‐Like Polypeptides as Simplified Analogues of Horseradish Peroxidase (HRP) Metalloenzymes

open access: yesMacromolecular Bioscience, Volume 24, Issue 10, October 2024.
Peroxidases like HRP are powerful biocatalysts for oxidation reactions. Inspired by HRP, star‐shaped polypeptide analogues are synthesized via a grafting‐from approach, ring‐opening polymerization, and manganese porphyrins. These analogues exhibit enhanced resistance to denaturation and catalytic activity in oxidation reactions with H2O2.

Biomimetic models for redox enzyme systems [PDF]

open access: yes, 2009
Supramolecular chemistry involves the study of noncovalent interactions that take place between molecules. A supramolecule or host-guest complex is formed when a noncovalent binding or complexation event occurs between two such molecules. Hydrogen bonds,
