Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation

Advanced Healthcare Materials, EarlyView.
This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

Novel 5-oxo-hexahydroquinoline derivatives: design, synthesis, in vitro P-glycoprotein-mediated multidrug resistance reversal profile and molecular dynamics simulation study [PDF]

, 2017
Overexpression of the efflux pump P-glycoprotein (P-gp) is one of the important mechanisms of multidrug resistance (MDR) in many tumor cells. In this study, 26 novel 5-oxo-hexahydroquinoline derivatives containing different nitrophenyl moieties at C-4 ...

Nanobody‐Conjugated Theranostic Prodrug Targeting αvβ3 Integrin Enables Precision Cancer Therapy With Real‐Time Imaging

Advanced Healthcare Materials, EarlyView.
The image shows a schematic form a nanobody‐conjugated theranostic prodrug (NBD) platform targeting tumor‐associated αvβ3 integrin. The NBD system integrates selective nanobody‐mediated tumor recognition, glutathione‐responsive disulfide cleavage for doxorubicin release, and aza‐BODIPY‐based near‐infrared fluorescence for real‐time imaging.

Antioxidant, anticancer and antimicrobial effects of In vitro developed protocorms of Dendrobium longicornu

Biotechnology Reports, 2020
In vitro seed germination and protocorms formation were successfully established in traditionally used Dendrobium longicornu. Fresh protocorms (178.34 g – 183.90 g) were produced on the elicitor of Alternaria sp, Bacillus subtilis and Fusarium solani ...

Immunomodulatory effects of 17-O-acetylacuminolide in RAW264.7 cells and HUVECs : involvement of MAPK and NF-κB pathways [PDF]

, 2014
The terpenoid 17-O-acetylacuminolide (AA) was shown to inhibit the production of several inflammatory mediators. However, the mechanisms by which this compound elicited its anti-inflammatory activity remain to be elucidated.

Biomimetic Copper Nanoparticles Coated with ACE2‐Overexpressing Membranes for Selective SARS‐CoV‐2 Neutralization and Disinfection

Advanced Healthcare Materials, EarlyView.
By fusing ACE2‐overexpressing membrane‐integrated liposome (MIL) with copper nanoparticles, the biomimetic Cu@MIL nanostructures were created that directly hijack the SARS‐CoV‐2 entry pathway. These particles combine potent virus‐targeting precision with intrinsic antiviral activity, achieving rapid neutralization and disinfection.

Designed Liquid Crystalline Nanoassemblies From Clinically Validated Polyunsaturated Lipids for Combined Antioxidant, Anti‐Apoptotic, and Neurotrophic Treatments

Advanced Healthcare Materials, EarlyView.
Ionizable lipid nanoparticles target multiple pathological pathways in neurodegeneration. The designed self‐assembled materials undergo a pH‐triggered structural transformation from a cubosome/hexosome coexistence to a hexosome phase, enhancing intracellular delivery of a multi‐target phytochemical formulation. The antioxidant‐loaded pH‐responsive LNPs

Engineering Resatorvid‐Loaded Sub‐Microgels of Epigallocatechin‐3‐gallate/Hyaluronic Acid to Treat Acute Lung Injury

Advanced Healthcare Materials, EarlyView.
This study presents HAEP@Res sub‐microgels as a lung‐targeted delivery system integrating antioxidant activity with anti‐inflammatory therapy. The sub‐microgels demonstrate excellent biocompatibility, efficiently scavenge intracellular ROS, and downregulate pro‐inflammatory cytokines and genes in a Bleo‐induced ALI mouse model. These findings highlight
