The DNA-encoded library (DEL) is a powerful hit-generation tool in drug discovery. This study describes a new DEL with a privileged scaffold quinazolin-4(3)-one developed by a robust DNA-compatible multicomponent reaction and a series of novel glutathione -transferase (GST) inhibitors that were identified through affinity-mediated DEL selection. A novel inhibitor was subsequently verified with an inhibitory potency value of 1.55 ± 0.02 μM against SjGST and 2.02 ± 0.20 μM against hGSTM2. Further optimization was carried out via various structure-activity relationship studies. And especially, the co-crystal structure of the compound with the SjGST was unveiled, which clearly demonstrated its binding mode was quite different from the known GSH-like compounds. This new type of probe is likely to play a different role compared with the GSH, which may provide new opportunities to discover more potent GST inhibitors.

Background: Nuclear factor erythroid-2-related factor 2 (Nrf2) could alleviate chronic obstructive pulmonary disease (COPD)-induced muscle dysfunction, and this study aimed to explore the specific mechanisms involved.
Methods: We successfully established a 12-week cigarette smoke-induced mouse model to replicate COPD-related sarcopenia. The Nrf2 agonist sulforaphane (SFN) and inhibitor ML385 were used to comprehensively assess the regulatory function of Nrf2 in COPD-related sarcopenia.

, an annual grass damaging wheat and canola fields in China, has evolved resistance to mesosulfuron-methyl, an acetolactate synthase (ALS)-inhibiting herbicide commonly used for its control. In this study, the resistant population (R) exhibited 22.93-fold resistance to mesosulfuron-methyl, and single-dose screening revealed cross-resistance to five other ALS-inhibiting herbicides.

Bromochloroacetamide (BCAcAm), an inevitable byproduct of the water treatment disinfection process, is widely detected in drinking water. Previous toxicological and in silico results suggested that developmental effects are associated with analogous chemical exposure; however, the key molecular events and underlying mechanisms remain unclear, especially in the early stages of aquatic organisms. In the present study, a zebrafish larval model was used to comprehensively assess the developmental toxicity of BCAcAm via transcriptional, metabolic, biochemical and morphological tests.
