Exploring the reactivity of N-heterocyclic diazoolefins

Diazo compounds of the type R1R2CN2 are widely used in organometallic catalysis and synthetic chemistry. Stable diazoolefins, R1R2C=CN2, have only been isolated recently. Diazoolefins undergo cycloaddition reactions and tend to be carbon donors when used a ...

Benzene with Alkyl Chains Is a Universal Scaffold for Multivalent Virucidal Antivirals

Jay-Ar Bautista Dela Cruz, Francesco Stellacci, Paulo Henrique Jacob Silva, Matteo Gasbarri, Lixia Wei, Yong Zhu, Heyun Wang, Sujeet Pawar

Most viruses start their invasion by binding to glycoproteins' moieties on the cell surface (heparan sulfate proteoglycans [HSPG] or sialic acid [SA]). Antivirals mimicking these moieties multivalently are known as broad-spectrum multivalent entry inhibito ...

Accessing elusive σ-type cyclopropenium cation equivalents through redox gold catalysis

Jérôme Waser, Matthew Wodrich, Xiangdong Li

Cyclopropenes are the smallest unsaturated carbocycles. Removing one substituent from cyclopropenes leads to cyclopropenium cations (C3 + systems, CPCs). Stable aromatic pi-type CPCs were discovered by Breslow in 1957 by removing a substituent on the aliph ...

Effect of the structural modification of Candesartan with Zinc on hypertension and left ventricular hypertrophy

Nikolaos Stergiopoulos, Augusto Martins Lima

Hypertension is the most common cause of left ventricular hypertrophy, contributing to heart failure progression. Candesartan (Cand) is an angiotensin receptor antagonist widely used for hypertension treatment. Structural modifications were previously perf ...

Metabolic, cellular and defense responses to single and co-exposure to carbamazepine and methylmercury in Dreissena polymorpha

Florian Frédéric Vincent Breider, Dominique Grandjean

Carbamazepine (CBZ) and Hg are widespread and persistent micropollutants in aquatic environments. Both pollutants are known to trigger similar toxicity mechanisms, e.g. reactive oxygen species (ROS) production. Here, their effects were assessed in the zebr ...

Method Development towards Orthogonal Electrophile Delivery

Lingxi Wang

Redox signaling events mediated by reactive electrophilic species (RES) are key players in several cellular processes. However, the studies on RES have been challenging due to their high reactivity towards numerous nucleophilic groups present in the cells ...

Ligand Effects in Low-Valent Co(I) Clathrochelate Complexes

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Ophélie Marie Planes

Clathrochelate complexes of cobalt are known in the oxidation states I, II, and III. Low-valent Co(I) complexes are highly reactive compounds, and there is only limited knowledge about their structures in the solid state. Herein, we describe the crystallog ...

Reactivity and biological activity of N,N,S-Schiff-base rhodium pentamethylcyclopentadienyl complexes

Paul Joseph Dyson, Lucinda Kate Batchelor

Neutral piano-stool complexes of the general formula [(eta(5)-C5Me5)Rh(L-OR)] (R = Me, 1; R = Et, 2; R = Pe(i), 3) have been prepared in alcohols (methanol, 1; ethanol, 2; isopropanol, 3) from the Schiff-base 5-methyl-4-{(pyridin-2-ylmethylene)amino}-4H-1, ...

Clofarabine Commandeers the RNR-alpha-ZRANB3 Nuclear Signaling Axis

Yimon Aye, Yi Zhao

Ribonucleotide reductase (RNR) is an essential enzyme in DNA biogenesis and a target of several chemotherapeutics. Here, we investigate how antileukemic drugs (e.g., clofarabine [CIF]) that target one of the two subunits of RNR, RNR-alpha, affect noncanoni ...

Measurement of Mitochondrial Mass and Membrane Potential in Hematopoietic Stem Cells and T-cells by Flow Cytometry

George Coukos, Olaia Maria Naveiras Torres-Quiroga, Alexandre Harari, Mukul Girotra, Nicola Vannini

A fine balance of quiescence, self-renewal, and differentiation is key to preserve the hematopoietic stem cell (HSC) pool and maintain lifelong production of all mature blood cells. In recent years cellular metabolism has emerged as a crucial regulator of ...

The orphan nuclear receptor LRH-1/NR5a2 critically regulates T cell functions

Kristina Schoonjans

LRH-1 (liver receptor homolog-1/NR5a2) is an orphan nuclear receptor, which regulates glucose and lipid metabolism, as well as intestinal inflammation via the transcriptional control of intestinal glucocorticoid synthesis. Predominantly expressed in epithe ...

Compact lensless digital holography

Manon Rostykus

Microscopy is of high interest for biology since it allows imaging features that are too small to be seen with naked eyes. However, cells are mostly transparent to visible and infrared light which makes it difficult to see with a traditional microscope. To ...
