Hydroxyl Radical-π Interaction in a Single Crystal.
JACS Au
January 2025
Department of Chemistry, Indian Institute of Technology Roorkee, Roorkee 247667, Uttarakhand, India.
Numerous attempts for organic radical stability mostly entail steric hindrance, spin-delocalization, supramolecular interaction with the host, π-π interactions, and hydrogen bonding. To date, there is no report of single crystals containing a hydroxyl radical (OH). In this work, we have stabilized OH in the crystal, which has been obtained from the filtrate after separating the precipitate of the chromenopyridine radical (DCP(2)) from the reaction mixture.

Background: Due to the divers biological applications of Cu(II) complexes, we in this study reports the various Cu(II) complexes. The study aims to synthesize and assess new Cu(II) complexes as powerful β-glucuronidase inhibitors.
Methods: Five Schiff base ligands and their complexes were synthesized, characterized, and screened against β-glucuronidase inhibitory activity.
White lies for coral reefs: Dynamics of two-patch coral reefs model with asymmetric dispersal.
J Theor Biol

Coral reef ecosystem is a crucial component of marine ecosystems and is undergoing severe degradation due to the combined dural impact of environmental changes and human activities. Soundscape technology is an innovative coral reef restoration approach that attracts fish to degraded reefs. Inspired by such technique, a five-dimensional mathematical dynamical model incorporating the asymmetric dispersal of parrotfish is formulated to characterize the dynamic interaction among macroalgae, coral, algal turf, and parrotfish in coral reef ecosystem.

Heart development involves the complex structural remodelling of a linear heart tube into an asymmetrically looped and ballooned organ. Previous studies have associated regional expansion of extracellular matrix (ECM) space with tissue morphogenesis during development. We have developed morphoHeart, a 3D tissue segmentation and morphometry software with a user-friendly graphical interface (GUI) that delivers the first integrated 3D visualisation and multiparametric analysis of both heart and ECM morphology in live embryos.

This paper presents a new strategy for the construction of the chiral 4-chromene skeleton. A series of chiral 2-trifluoromethyl-4-(indol-3-yl)-4-chromenes were synthesized in moderate to good yields (60-92%) with excellent enantioselectivity (up to 97% ee) through the palladium-catalyzed asymmetric condensation of 2-chromenes and indoles. These trifluoromethylated, stereochemically rich building blocks hold potential value in medicinal chemistry.
