Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.

Green Methodologies for Copper(I)-Catalyzed Azide-Alkyne Cycloadditions: A Comparative Study

open access: yesMolecules, 2019
Successful copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reactions may be achieved by several methods. In this paper, four synthetic protocols were performed for direct comparison of time required for the synthesis, yield, and purity of the 1H-1,

Post-Functionalization of Organometallic Complexes via Click-Reaction

open access: yesMolecules, 2022
CuAAC (Cu catalyzed azide-alkyne cycloaddition) click-reaction is a simple and powerful method for the post-synthetic modification of organometallic complexes of transition metals. This approach allows the selective introduction of additional donor sites

Postsynthetic modification of zirconium metal-organic frameworks [PDF]

open access: yes, 2016
Metal-organic frameworks (MOFs) have been in the spotlight for a number of years due to their chemical and topological versatility. As MOF research has progressed, highly functionalised materials have become desirable for specific applications, and in ...

One‐Step Glycoengineering of NK Cells With High‐Affinity Siglec Ligands for Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study develops an engineered NmCSS enzyme with improved activity for bulky group modified sialic acids, enabling efficient synthesis of structurally diverse sialoside analogs in a single step. Glycan microarray screening identified Siglec high‐affinity ligands, which were incorporated onto natural killer (NK) cells via a one‐pot enzymatic system ...

Synergistische Entwicklungsstrategien von Inhibitoren gegen humane UDP‐Galactose‐4‐Epimerase

open access: yesAngewandte Chemie, EarlyView.
Die Epimerase GalE ist essenziell für die Biosynthese von krebsrelevanten O‐GalNAc Glykanen. Wir verwenden orthogonales, strukturbasiertes Screening niedermolekularer Fragmente an, um kovalente und nichtkovalente Inhibitoren gegen GalE mit nicht mehr als 22 optimierten Verbindungen zu erhalten.

Synthesis of substituted triazole–pyrazole hybrids using triazenylpyrazole precursors

open access: yesBeilstein Journal of Organic Chemistry
A synthesis route to access triazole–pyrazole hybrids via triazenylpyrazoles was developed. Contrary to existing methods, this route allows the facile N-functionalization of the pyrazole before the attachment of the triazole unit via a copper-catalyzed ...

A ribose-functionalized NAD+ with unexpected high activity and selectivity for protein poly-ADP-ribosylation. [PDF]

open access: yes, 2019
Nicotinamide adenine dinucleotide (NAD+)-dependent ADP-ribosylation plays important roles in physiology and pathophysiology. It has been challenging to study this key type of enzymatic post-translational modification in particular for protein poly-ADP ...
