opXRD: Open Experimental Powder X‐Ray Diffraction Database

open access: yesAdvanced Intelligent Discovery, EarlyView.
We introduce the Open Experimental Powder X‐ray Diffraction Database, the largest openly accessible collection of experimental powder diffractograms, comprising over 92,000 patterns collected across diverse material classes and experimental setups. Our ongoing effort aims to guide machine learning research toward fully automated analysis of pXRD data ...

The Structure of Nitro‐ and Polynitropyrazoles: X‐Ray Crystallography Versus Theoretical Calculations

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Abstract This publication presents the geometries of 157 nitro‐ and polynitropyrazoles. Among these, 109 compounds were theoretically studied using mainly the B3LYP/6–311++G(d,p) level of theory. Three‐parameter Lee‐Yang‐Parr (B3LYP) is a density functional theory (DFT) method widely used in computational chemistry and constitutes an acceptable ...

Piano‐Stool Rhodium(V) and Rhodium(IV) Intermediates in C─H Functionalization and B─H Functionalization: Mechanistic Insights and Emerging Reactivity

open access: yesAsian Journal of Organic Chemistry, EarlyView.
High‐valent Rh(IV) and Rh(V) species have been invoked to rationalize enhanced catalytic reactivity. This review examines evidence for both, emphasizing reactions proceeding through the Rh(III)/Rh(IV)/Rh(II) cycle. While Rh(V) intermediates are computationally supported, experimental evidence is limited; Rh(IV) species are supported by both theory and ...

Fragment‐Based Drug Discovery of Novel High‐affinity, Selective, and Anti‐inflammatory Inhibitors of the Keap1‐Nrf2 Protein‐Protein Interaction

open access: yesAngewandte Chemie, EarlyView.
We developed potent and selective noncovalent Keap1‐Nrf2 inhibitors through a structure‐guided fragment‐based approach. These nanomolar inhibitors activate Nrf2‐controlled genes, suppress inflammation via NLRP3 and STING pathways, and exhibit distinct transcriptional profiles compared to covalent Nrf2 activators, offering promising chemical probes and ...

Brassinin from Brassica campestris L. inhibits colorectal cancer by inducing p62/NRF2/GPX4‐regulated ferroptosis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
BSN suppresses the cell viability of colorectal cancer by inducing GPX4‐regulated ferroptosis. BSN may bind to NRF2 protein to inactivate the NRF2 signaling, inhibiting the expression of p62 and HO‐1. Abstract Background Indole phytoalexins, plant‐derived compounds present in cruciferous vegetables, have demonstrated anticancer properties.
