At the molecular level, 5-amino-1MQ functions as a competitive inhibitor of NNMT, demonstrating remarkable potency with an IC of 1.2 0.1 M under standard assay conditions (50 M SAM, 100 M nicotinic acid). This represents a dramatic 10-fold improvement over the parent compound 1-methylquinolinium, achieved through strategic amino group substitution that enhances binding affinity to the NNMT active site. The compound's mechanism centers on preventing the methylation of nicotinamide to 1-methylnicotinamide (1-MNA), thereby preserving nicotinamide for recycling back to NAD+ through the salvage pathway. This intervention effectively blocks what researchers have termed the "NNMT metabolic drain" a process that simultaneously depletes NAD+ precursors and consumes cellular methylation capacity
GLP-1, short for glucagon-like peptide-1, mimics a naturally occurring hormone that helps regulate blood sugar and appetite
By quantitatively analyzing the differences in street spatial quality in Xi'an, the research results can provide scientific references for urban street planning, functional positioning and management, and provide a reference for the development of spatial quality improvement strategies in other cities.Speaker: Mr mengde zheng (Xian University of Architecture and Technology) 568 Spatiotemporal perception of disasters based on social media data in the context of climate change: A case study of Shanghai The frequent occurrence of extreme weather events has brought serious impacts on cities under the background of climate change
