Stereochemistry-Controlled Mechanical Properties and Degradation in 3D-Printable Photosets.

open access: yesJournal of the American Chemical Society, 2021
Stereochemistry provides an appealing handle by which to control the properties of small molecules and polymers. While it is established that stereochemistry in linear polymers affects their bulk mechanical properties, the application of this concept to ...

Synthesis of New C-3 Substituted Kynurenic Acid Derivatives

open access: yesMolecules, 2020
The application of kynurenic acid (KYNA) as an electron-rich aromatic system in the modified Mannich reaction has been examined. The extension possibility of the reaction was tested by using amines occurring in a number of bioactive products, such as ...

Fast and Accurate Prediction of Refractive Index of Organic Liquids with Graph Machines

open access: yesMolecules, 2023
The refractive index (RI) of liquids is a key physical property of molecular compounds and materials. In addition to its ubiquitous role in physics, it is also exploited to impart specific optical properties (transparency, opacity, and gloss) to ...

A global Ramachandran score identifies protein structures with unlikely stereochemistry

open access: yesbioRxiv, 2020
Ramachandran plots report the distribution of the (φ, Ψ) torsion angles of the protein backbone and are one of the best quality metrics of experimental structure models. Typically, validation software reports the number of residues belonging to “outlier”,

Synthesis and Conformational Analysis of Naphthoxazine-Fused Phenanthrene Derivatives

open access: yesMolecules, 2020
The synthesis of new phenanthr[9,10-e][1,3]oxazines was achieved by the direct coupling of 9-phenanthrol with cyclic imines in the modified aza-Friedel–Crafts reaction followed by the ring closure of the resulting bifunctional aminophenanthrols with ...

Advancing peptide siRNA-carrier designs through L/D-amino acid stereochemical modifications to enhance gene silencing

open access: yesMolecular Therapy: Nucleic Acids, 2021
The 599 peptide has been previously shown to effectively deliver small interfering RNAs (siRNAs) to cancer cells, inducing targeted-oncogene silencing, with a consequent inhibition of tumor growth. Although effective, this study was undertaken to advance

Solvent-Free C-3 Coupling of Azaindoles with Cyclic Imines

open access: yesMolecules, 2019
By direct coupling 7-azaindole and cyclic imines, such as 3,4-dihydroisoquinoline, 6,7-dihydrothieno[3,2-c]pyridine, 3,4-dihydro-β-carboline, and 4,5-dihydro-3H-benz[c]azepine, new 3-substituted 7-azaindole derivatives have been synthesized.

Femtosecond dynamics of hydrogen elimination: benzene formation from cyclohexadiene [PDF]

open access: yes, 2000
Using femtosecond-resolved mass spectrometry in a molecular beam, we report real-time study of the hydrogen elimination reaction of 1,4-cyclohexadiene. The experimental observation of the ultrafast stepwise H-elimination elucidates the reaction dynamics ...
