GMP

GMP (CAS No.: 85-32-5) is a naturally occurring purine nucleotide, also known as guanosine 5′-monophosphate, consisting of a guanine base linked to a ribose sugar with a single phosphate group, and is widely distributed in biological systems as a fundamental component of nucleic acid metabolism. It plays essential roles in cellular processes including energy metabolism, intracellular signaling, and the regulation of gene expression, particularly in pathways associated with nucleotide turnover and lipid metabolism. GMP functions as a precursor and intermediate in the biosynthesis of guanine nucleotides and is involved in metabolic networks linked to disorders such as purine metabolism deficiencies and related enzymatic pathway disruptions. In neurobiological research, GMP has been characterized as a weak agonist of ionotropic glutamate receptors, modulating glutamatergic signaling and influencing neuronal activity, with context-dependent effects that may include reduced excitatory transmission at lower concentrations and cytotoxic outcomes at elevated levels. Its biochemical activity is typically investigated in vitro across low micromolar to higher concentration ranges depending on assay conditions and cellular context. GMP is commonly utilized in studies of nucleotide metabolism, enzymatic regulation, receptor pharmacology, and metabolic pathway analysis, as well as in cell-based and biochemical assays aimed at elucidating signaling mechanisms and screening modulators of purine-related pathways, where experimental concentrations and exposure conditions are adjusted according to specific research objectives.
