Glucoconjugated Dinuclear Copper(II) Complex: An Efficient Catalyst for Stereoselective Synthesis of Trisubstituted Propargylamines via Solvent-free A Coupling Reaction.

Development of catalytic systems using nontoxic natural precursors is the need of the era, and along this line, we have synthesized a new D-glucose derived ligand (4,6-O-ethylidene-N-(2-hydroxy-4-(octyloxy)benzylidene)-β-D-glucopyranosylamine) and its dinuclear copper(II) complex. The molecular structure of the complex has been established by single-crystal X-ray diffraction studies and detailed noncovalent intermolecular interactions present in it have been explored by Hirshfeld surface analysis. Further, the complex has been used as a catalyst in the enantioselective (87-99 % ee) synthesis of propargylamines in good to excellent yield (82-95 %) via aldehyde-amines-alkynes (A) coupling reaction under solvent-free condition.

Clinical Profiles of Neonates Born to COVID-19 Positive Mothers in a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Nepal is one of the countries which has been hit hard by the COVID-19 pandemic and has resulted in high morbidity and mortality across all age groups including neonates. There has been a paucity of studies regarding maternal to neonatal COVID-19 transmission and the published studies also have a poor sample size to reach any definite conclusion. Hence this study was carried out to see the clinical profiles of neonates born to COVID-19 mothers.

Recombinant human interferon regulatory factor-1 (IRF-1) protein expression and solubilisation study in Escherichia coli.

Interferon regulatory factor-1 (IRF-1) is a tumor suppressor gene, which encodes a mammalian transcription factor that serves various vital functions in a cell, such as cell cycle regulation, immunomodulation, and antiviral response. We report full-length human IRF-1 cDNA cloning and expression in E. coli/BL21 cells with complete solubilisation of recombinant protein.

Dietary Polysaccharides in the Amelioration of Gut Microbiome Dysbiosis and Metabolic Diseases.

The prevalence of metabolic diseases including obesity, diabetes, cardiovascular diseases, hypertension and cancer has evolved into a global epidemic over the last century. The rate of these disorders is continuously rising due to the lack of effective preventative and therapeutic strategies. This warrants for the development of novel strategies that could help in the prevention, treatment and/ or better management of such disorders.
