AI Article Synopsis
- The research introduces a new (arene)RuCl(monosulfonamide) catalyst for the dynamic kinetic resolution of β-aryl α-keto esters.
- This process produces three stereocenters with high selectivity via a reduction/lactonization mechanism.
- The resulting γ-butyrolactones are enantioenriched and versatile for further synthetic modifications.
Article Abstract
The dynamic kinetic resolution of β-aryl α-keto esters has been accomplished using a newly designed (arene)RuCl(monosulfonamide) transfer hydrogenation catalyst. This dynamic process generates three contiguous stereocenters with remarkable diastereoselectivity through a reduction/lactonization sequence. The resulting enantioenriched, densely functionalized γ-butyrolactones are of high synthetic utility, as highlighted by several secondary derivatizations.

Lung cancer is the leading cause of cancer-related fatalities globally, accounting for the highest mortality rate among both men and women. Mutations in the epidermal growth factor receptor (EGFR) gene are frequently found in non-small cell lung cancer (NSCLC). Since curcumin and CB[2]UN support various medicinal applications in drug delivery and design, we investigated the effect of curcumin and CB[2]UN-based drugs in controlling EGFR-mutant NSCLC through a dodecagonal computational approach.

To investigate heterogeneity of fibroblasts in human fetal skin, we analysed published single-cell RNA sequencing data (8 and 16 post conception weeks (PCW)) and performed single-molecule fluorescence in situ hybridisation to map their spatial distribution and predicted dynamic interactions. Clustering revealed 8 fibroblast populations with developmental stage-specific abundance changes. Proliferative cells (MKI67+) were present at all stages.

Introduction: Breathing and postural control is reported to be both neuromuscularly and mechanically interdependent. To date, the effects of voluntary abdominal and thoracic breathing (VAB and VTB) on the EMG activity of muscles involved in both respiratory and postural functions, as well as gait biomechanics related to these breathing patterns, have not been investigated in young, healthy adults. The aim of the study was to evaluate the EMG responses of neck and trunk muscles, as well as the kinematic, stability, and kinetic parameters of gait induced by VAB and VTB compared to involuntary breathing (INB).

Hydrogen/deuterium exchange mass spectrometry (HDX-MS) is a powerful technique to interrogate protein structure and dynamics. With the ability to study almost any protein without a size limit, including intrinsically disordered ones, HDX-MS has shown fast growing importance as a complement to structural elucidation techniques. Current experiments compare two or more related conditions (sequences, interaction partners, excipients, conformational states, etc.
