Synthesis of 6- or 8-Carboxamido Derivatives of Imidazo[1,2-a]pyridines via a Heterogeneous Catalytic Aminocarbonylation Reaction

Molecules
Imidazo[1,2-a]pyridines and especially their amide derivatives exhibit a wide range of favourable pharmacological properties. In this work, Pd-catalysed carbonylation was used for the first time for the introduction of the carboxamide moiety into ...

How Secondary and Tertiary Amide Moieties are Molecular Stations for Dibenzo-24-crown-8 in [2]Rotaxane Molecular Shuttles?

Molecules, 2017
Interlocked molecular machines like [2]rotaxanes are intriguing aesthetic molecules. The control of the localization of the macrocycle, which surrounds a molecular axle, along the thread leads to translational isomers of very different properties ...

Encapsulation of Small Extracellular Vesicles into Selectively Disassemblable Shells of PEGylated Metal‐Phenolic Networks

Advanced Healthcare Materials, EarlyView.
Small extracellular vesicles (sEVs) are encapsulated into protective shells composed of metal‐phenolic networks (MPNs) and secondary poly(ethylene glycol) layers. This surface modification approach enhances the storage stability of sEVs while maintaining their integrity and functionality. The shells can be selectively disassembled under mild conditions.

Nucleophilic Addition Reactions to 10-Acetonitrilium Derivative of nido-Carborane and Intramolecular NH⋯HB Interactions in N-Alkyl Amidines 10-RNHC(Me)=NH-7,8-C₂B₉H₁₁

Molecules
The addition reactions of water, alcohols, and primary and secondary amines to the 10-acetonitrilium derivative of nido-carborane were studied. Hydrolysis of 10-MeC≡N-7,8-C2B9H11 results in iminol 10-MeC(OH)=HN-7,8-C2B9H11, which, on treatment with a ...

Practical Spectrophotometric Assay for the \u3cem\u3edapE\u3c/em\u3e-Encoded \u3cem\u3eN\u3c/em\u3e-Succinyl-L,L-Diaminopimelic Acid Desuccinylase, a Potential Antibiotic Target [PDF]

, 2018
A new enzymatic assay for the bacterial enzyme succinyl-diaminopimelate desuccinylase (DapE, E.C. 3.5.1.18) is described. This assay employs N6-methyl-N2-succinyl-L,L-diaminopimelic acid (N6-methyl-L,L-SDAP) as the substrate with ninhydrin used to detect

Tri‐Layered Bioactive Cutaneous Scaffold with Integrated Bioactive Metal Organic Frameworks to Promote Full‐Thickness Infected Diabetic Wound Healing: Multifaceted Therapeutic Strategies

Advanced Healthcare Materials, EarlyView.
The limitations of existing clinical treatments highlight the need for a more comprehensive strategy for addressing infected diabetic wounds. A tri‐layered scaffold is developed to deliver therapeutics loaded in CuBDC and ZIF‐8 MOFs that are tailored to the requirements of deep‐infected diabetic wounds.

Inferential protein structure determination and refinement using fast, electronic structure based backbone amide chemical shift predictions [PDF]

arXiv, 2015
This report covers the development of a new, fast method for calculating the backbone amide proton chemical shifts in proteins. Through quantum chemical calculations, structure-based forudsiglese the chemical shift for amidprotonen in protein has been parameterized. The parameters are then implemented in a computer program called Padawan.
