Inhalable Polymeric Nanoparticle Containing Triphenylphosphanium Bromide‐modified Sonosensitizer for Enhanced Therapy of Acute Bacterial Pneumonia

Advanced Science, EarlyView.
Bacterial pneumonia is the sixth leading cause of death. In this study, an inhalable polymeric nanoparticle NPFCPS‐P is developed, which under US stimulation showed high efficacy in the treatment of acute bacterial pneumonia. This nanoplatform would be much less prone to select bacterial resistance and represented a promising measure for antibiotics ...

Efficient Nickel Precatalysts for Suzuki‐Miyaura Cross‐Coupling of Aryl Chlorides and Arylboronic Acids Under Mild Conditions

Angewandte Chemie, EarlyView.
The synthesis and catalytic properties of Ni(II) complexes, with the general formula Ni(NHC)[P(OR)3](Ar)Cl, are described. These air‐stable complexes are effective under mild conditions and low catalytic loading for the Suzuki‐Miyaura cross‐coupling for a range of electronically and sterically differentiated coupling partners.

Multi-reference protocol for (auto)ionization spectra: application to molecules [PDF]

, 2019
We present the application of the spherically averaged continuum model to the evaluation of molecular photoelectron and resonant Auger electron spectra. In this model, the continuum wave function is obtained in a numerically efficient way by solving the radial Schr\"odinger equation with a spherically averaged molecular potential.

HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

Advanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

Beyond Structure: Methylation Fine‐Tunes Stability and Folding Kinetics of bcl2Mid G‐Quadruplex

Angewandte Chemie, EarlyView.
The introduction of a single 5‐methylcytosine into a G‐rich sequence originating from the B‐cell lymphoma 2 (BCL2) gene promoter affects both the folding kinetics and thermodynamics of the two G4 structures and thus plays a crucial role in regulating G4 folding pathways, which has significant implications for the control of gene expression.

Solution of the Crow-Kimura and Eigen models for alphabets of arbitrary size by Schwinger spin coherent states [PDF]

, 2009
To represent the evolution of nucleic acid and protein sequence, we express the parallel and Eigen models for molecular evolution in terms of a functional integral representation with an $h$-letter alphabet, lifting the two-state, purine/pyrimidine assumption often made in quasi-species theory. For arbitrary $h$ and a general mutation scheme, we obtain

Pyrimidine biosynthesis in Pseudomonas veronii and its regulation by pyrimidines

Microbiological Research, 2012
Pyrimidine biosynthesis in the nutritionally versatile bacterium Pseudomonas veronii ATCC 700474 appeared to be controlled by pyrimidines. When wild type cells were grown on glucose in the presence of uracil, four enzyme activities were depressed while all five enzyme activities increased in succinate-grown cells supplemented with uracil.

A cytotoxic survey on 2‐amino‐1H‐imidazol based synthetic marine sponge alkaloid analogues

Drug Development Research, Volume 83, Issue 8, Page 1906-1922, December 2022., 2022
Abstract Here, we describe the synthesis and biologic activity evaluation of 20 novel synthetic marine sponge alkaloid analogues with 2‐amino‐1H‐imidazol (2‐AI) core. Cytotoxicity was tested on murine 4T1 breast cancer, A549 human lung cancer, and HL‐60 human myeloid leukemia cells by the resazurin assay.

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.
