Targeted Degradation of Picornaviral 3C Protease via PROTACs Confers High Barrier to Viral Resistance and Broad‐Spectrum Antiviral Activity

Advanced Science, EarlyView.
This study reports D34 as the first PROTAC degrader that targets the 3C protease of picornaviruses. D34 effectively degrades EV71 3C protease via the ubiquitin‐proteasome pathway. More importantly, D34 exhibits a high resistance barrier and shows broad‐spectrum antiviral activity against multiple picornaviruses, highlighting its potential as a novel ...

Radical‐Mediated In Situ Fluorescence Dye Deposition: A Simple Interfacial Signal Amplification Reaction for Ultrasensitive Immunoassay on Barcode Beads

Advanced Science, EarlyView.
A radical‐mediated in situ fluorescence dye deposition (RIFD) reaction containing merely three elements of beads, dyes, and radicals is discovered for the first time, and its underlying mechanism is elucidated. This simple RIFD enables the interfacial and ultrafast deposition of free dyes onto barcode beads, serving as a powerful signal amplification ...

Molecular Dynamics‐Guided Sterol Engineering of mRNA‐Lipid Nanoparticles Reprograms Biodistribution and Enhances Spleen‐Selective Immunity

Advanced Science, EarlyView.
Sterol engineering enables precise control of mRNA lipid nanoparticles by tuning membrane organization. Replacing cholesterol with bile acid‐derived sterols redirects protein expression from the liver to the spleen. Notably, CA‐20 LNP enhances antigen‐specific immune responses while exhibiting a favorable safety profile, highlighting sterols as a ...

Programmable Nanobody‐Targeting Chimeras Enable Intracellular Viral Protein Degradation

Advanced Science, EarlyView.
Nab‐TAC enables targeted degradation of HBV surface antigen (HBsAg) in vivo. By fusing nanobody‐based recognition domains with programmable proteasome‐recruiting degradation signals, Nab‐TAC reduces HBsAg levels in a hydrodynamic HBV mouse model. ABSTRACT Chronic hepatitis B virus (HBV) infection remains a major global health challenge, largely because

The glycans of horseradish peroxidase

Carbohydrate Research, 1996
Horseradish peroxidase (E.C. 1.11.1.7) isozyme c (HRPc) is a glycoprotein found to contain 21.8% carbohydrate with the average composition: 2 mol GlcNAc, 2.6 mol Man, and 0.8 mol each of Fuc and Xyl. The oligosaccharides of HRPc were investigated by a combination of High pH Anion-Exchange Chromatography with Pulsed Amperometric Detection, methylation ...

Stereospecificity of horseradish peroxidase

Biological Chemistry, 2004
We report here on the stereospecificity observed in the action of horseradish peroxidase (HRPC) on monophenol and diphenol substrates. Several enantiomers of monophenols and o-diphenols were assayed: L-tyrosinol, D-tyrosinol, L-tyrosine, DL-tyrosine, D-tyrosine, L-dopa, DL-dopa, D-dopa, L-alpha-methyldopa, DL-alpha-methyldopa, DL-adrenaline, D ...

Horseradish peroxidase C

Molecular and Cellular Biochemistry, 1981
Horseradish peroxidase C (HRP; ferric) reacts with H2O2 to form Compound I, with an equilibrium constant of about 10(14) M-1. Two-step reduction of Compound I to Compound II and further to the ferric enzyme occurs reversibly at Eo' values of 0.90 and 0.93 V (pH 7.0), respectively.

Chromogenic substrates for horseradish peroxidase

Analytical Biochemistry, 1991
Two new detection systems for horseradish peroxidase (HRP) have been developed for the staining of membranes used in immunoassays. These systems use dimethyl or diethyl analogues of p-phenylenediamine with 4-chloro-1-naphthol to generate a blue product or 3-methyl-2-benzothiazolinone hydrazone with 4-chloro-1-naphthol to generate a red product.
