3‐[3‐(Phenalkylamino)cyclohexyl]phenols: Synthesis, biological activity, and in silico investigation of a naltrexone‐derived novel class of MOR‐antagonists

Archiv der Pharmazie, Volume 356, Issue 1, January 2023., 2023
Based on a simplified version of the morphinan scaffold, 3‐[3‐(phenalkylamino)cyclohexyl]phenol analogues were designed, synthesized and evaluated for their µ‐opioid receptor (MOR) antagonist activity in vitro and in silico. Docking studies indicate a peculiar combination of C‐1 stereochemistry and N‐substitutions as feasibly essential for MOR‐ligand ...

Decoding the Chemical Language of Ribosomally Synthesized and Post‐Translationally Modified Peptides from the Untapped Archaea Domain

Angewandte Chemie, EarlyView.
Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

Automated Identification and Classification of Stereochemistry: Chirality and Double Bond Stereoisomerism [PDF]

arXiv, 2013
Stereoisomers have the same molecular formula and the same atom connectivity and their existence can be related to the presence of different three-dimensional arrangements. Stereoisomerism is of great importance in many different fields since the molecular properties and biological effects of the stereoisomers are often significantly different.

In-Pocket 3D Graphs Enhance Ligand-Target Compatibility in Generative Small-Molecule Creation [PDF]

arXiv, 2022
Proteins in complex with small molecule ligands represent the core of structure-based drug discovery. However, three-dimensional representations are absent from most deep-learning-based generative models. We here present a graph-based generative modeling technology that encodes explicit 3D protein-ligand contacts within a relational graph architecture.

Stereochemistry of post-transition metal oxides: revision of the classical lone pair model.

Chemical Society Reviews, 2011
The chemistry of post transition metals is dominated by the group oxidation state N and a lower N-2 oxidation state, which is associated with occupation of a metal s(2) lone pair, as found in compounds of Tl(I), Pb(II) and Bi(III).

Circularly Polarized Luminescence Inversion in AIE‐Active Crystal Enabled by Solvent‐Induced Transition Dipole Moment Regulation

Aggregate, EarlyView.
Crystals of chiral AIEgens exhibit achiral solvent‐induced CPL sign inversion with good optical waveguide properties, while the same helical structure and molecular chirality are retained in the crystalline state. Nonbonding interactions between the cocrystallized solvent molecules and AIEgens affect the θμ,m (S1 → S0) of electric and magnetic ...

A Key Fragment in Carbon Schwarzite Unit Cells and Its Triple [6]Helicene Precursor

Angewandte Chemie, EarlyView.
Adjusting the conditions of Scholl reactions has enabled the selective synthesis of polycyclic arenes with two related π‐skeletons. One π‐skeleton is a key fragment of theoretical carbon schwarzites, while the other is a triple [6]helicene, which exhibits unique supramolecular structures in the clathrate with chloroform and an absorption dissymmetry ...

Unscrambling Structured Chirality with Structured Light at Nanoscale Using Photo-induced Force [PDF]

, 2018
We introduce a microscopy technique that facilitates the prediction of spatial features of chirality of nanoscale samples by exploiting photo-induced optical force exerted on an achiral tip in the vicinity of the test specimen. The tip-sample interactive system is illuminated by structured light to probe both the transverse and longitudinal (with ...

Mechanism of Cationic Peptide‐Induced Assembly of Gold Nanoparticles: Modulation of Electrostatic Repulsion

Aggregate, EarlyView.
Cationic peptides aggregate citrate‐capped gold nanoparticles (AuNPs), producing a colorimetric change. The figure highlights the interplay between the intermolecular attractive and repulsive forces governing the colloidal stability of the nanoparticles.
