Chalcones are easily accessible synthetic building blocks that are used in various heterocyclic syntheses. The rearrangement reaction using an oxidant is a characteristic conversion of chalcones, but applications to organic synthesis have been limited. Here, the development of a new method for synthesizing 3-acylindoles and azaisoflavones using a chalcone rearrangement strategy with hypervalent iodine reagents was described. Furthermore, the obtained new insight was applied to the selective synthesis of two benzofuran isomers from 2-hydroxychalcone derivatives and have demonstrated this method to the synthesis of the natural product, puerariafuran.

Deciphering the interplay between biology and physics with a finite element method-implemented vertex organoid model: A tool for the mechanical analysis of cell behavior on a spherical organoid shell.

Understanding the interplay between biology and mechanics in tissue architecture is challenging, particularly in terms of 3D tissue organization. Addressing this challenge requires a biological model enabling observations at multiple levels from cell to tissue, as well as theoretical and computational approaches enabling the generation of a synthetic model that is relevant to the biological model and allowing for investigation of the mechanical stresses experienced by the tissue. Using a monolayer human colon epithelium organoid as a biological model, freely available tools (Fiji, Cellpose, Napari, Morphonet, or Tyssue library), and the commercially available Abaqus FEM solver, we combined vertex and FEM approaches to generate a comprehensive viscoelastic finite element model of the human colon organoid and demonstrated its flexibility.

is a Gram-positive bacterium that is responsible for severe nosocomial infections. The rise of multidrug-resistant strains, which can pose significant health threats, prompts the development of new treatment interventions, and much attention has been directed at the development of prophylactic and therapeutic vaccination strategies. Capsular polysaccharides (CPs) are key protective elements of the cell wall and have been proposed as promising candidate antigens.

Neo-vascularization plays a key role in achieving long-term viability of engineered cells contained in medical implants used in precision medicine. Moreover, strategies to promote neo-vascularization around medical implants may also be useful to promote the healing of deep wounds. In this context, a biocompatible, electroconductive borophene-poly(ε-caprolactone) (PCL) 3D platform is developed, which is called VOLT, to support designer cells engineered with a direct-current (DC) voltage-controlled gene circuit that drives secretion of vascular endothelial growth factor A (VEGFA).

Oral ganaxolone (ZTALMY), a synthetic analogue of the endogenous neuroactive steroid allopregnanolone, acts as a positive allosteric modulator of synaptic and extra-synaptic γ-aminobutyric acid (GABA) type A receptor function in the CNS. In the EU and the UK, it is approved for the adjunctive treatment of epileptic seizures associated with cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) in patients aged 2-17 years. In a multinational phase III study (Marigold), 17 weeks' therapy with adjunctive ganaxolone, administered orally three times daily with food, significantly reduced 28-day major motor seizure frequency from baseline versus placebo in patients aged 2-19 years with CDD-associated refractory epilepsy.

Background: Globally, Breast Cancer (BC) is the most frequent cancer in women and has a major negative impact on the physical and emotional well-being of its patients as well as one of the most common cancers to be diagnosed. Numerous studies have been published to identify various molecular pathways, including PI3K/AKT/PTEN. Moreover, growing evidence suggests that miRNAs have been found to play a vital role in the growth and carcinogenesis of tumors.
