Cholesterol‐Mediated Metabolic‐mechanotransductive Crosstalk Orchestrates Castration Resistance in Prostate Cancer

open access: yesAdvanced Science, EarlyView.
Full androgen deprivation (FAD) induces paracrine cholesterol in prostate cancer that drives the polarization of cancer‐associated fibroblasts (CAFs) and subsequent elevated matrix stiffness. Matrix stiffness in turn potentiates tumor cell survival under FAD pressure via dual mechanotransductive activation of the IRE1α‐XBP1s stress‐response axis ...

Molecular Mobility of N‐Acetylgalactosamine‐Modified Cyclodextrins on a Polyrotaxane for Highly Efficient Liver Targeting of Antibody Chimeras and Genome‐Editing Ribonucleoproteins

open access: yesAdvanced Science, EarlyView.
Monovalent N‐acetylgalactosamine (GalNAc)‐modified polyrotaxane enables efficient liver targeting by utilizing ligand mobility. The sliding and rotating cyclic components i.e., cyclodextrin in the polyrotaxane dynamically cluster GalNAc moieties, thereby mimicking trivalent interactions with asialoglycoprotein receptors.

Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing

Comparison of Association Constants of Cyclodextrins and Their tert-Butyl Derivatives With Halogenbenzoic Acids and Acridine Derivatives

open access: yesMolecules, 2001
Association constants of complexes of a new class of cyclodextrin alkyl derivatives - randomly susbstituted tert-butyl derivatives (TB-CDs) with complete set of mono-halobenzoic acids and acridine derivatives were measured using capillary electrophoresis

Modeling the effects of cyclodextrin on intracellular membrane vesicles from Cos-7 cells prepared by sonication and carbonate treatment [PDF]

open access: yesPeerJ, 2015
Cholesterol has important functions in the organization of membrane structure and this may be mediated via the formation of cholesterol-rich, liquid-ordered membrane microdomains often referred to as lipid rafts.

Real‐Time Stress Visualization of Hydrogels Enabled by Supramolecularly Switched Stretch‐Induced Phase Separation

open access: yesAdvanced Science, EarlyView.
Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Nano‐Confined Radical Anion as An NIR‐II Photothermal Immunogenic Amplifier for In Situ Cancer Vaccination

open access: yesAdvanced Science, EarlyView.
A nano‐confined radical anion acts as a photothermal immunogenic amplifier. Kinetically stabilized nanoparticles couple high near‐infrared‐II (NIR‐II) photothermal efficacy with glutathione (GSH) depletion to boost reactive oxygen species (ROS) and immunogenic cell death (ICD).

Artificial Host‐Guest Recognition Directs Glycometabolically Engineered Macrophages to Tumors

open access: yesAdvanced Science, EarlyView.
Glycoengineered supramolecular macrophages (GSAR‐M) are developed using glycometabolic labeling for bioorthogonal host‐guest tumor targeting. This engineering approach unexpectedly enhances macrophage migration, phagocytosis, and pseudopodia formation. Consequently, GSAR‐M demonstrate robust tumor‐targeting specificity, effectively arrest tumor growth,

Virus‐Mediated Self‐Assembly of Functional Cyclodextrins for Antiviral Inhibition

open access: yesAngewandte Chemie, EarlyView.
A sialic acid (SA)‐functionalized cyclodextrin (CD) self‐assembles on SARS‐CoV‐2 through ligand–receptor recognition, nucleating cooperative supramolecular polymer growth that blocks infection. The adaptive assembly requires both ligand binding and host–guest polymerization, remains active across variants, and can be tuned by coassembly, establishing ...
