N1,N12-Diacetylspermine (hydrochloride)

N1,N12-Diacetylspermine (hydrochloride) (CAS No.: 77928-71-3) is a diacetylated derivative of the endogenous polyamine spermine and is widely recognized as a biologically relevant small molecule in polyamine metabolism research and cancer biomarker discovery. As a metabolite derived from spermidine through enzymatic pathways, it participates in the regulation of cellular proliferation, differentiation, and protein synthesis, partly through modulation of polyamine oxidase activity, for which it serves as an efficient substrate with enhanced catalytic turnover compared to non-acetylated counterparts. Through its involvement in polyamine homeostasis, this compound is associated with key signaling processes governing cell growth and calcium-dependent immune responses, and its elevated levels have been consistently correlated with tumor development, supporting its utility as a diagnostic and prognostic biomarker in oncology research. In experimental systems, N1,N12-Diacetylspermine (hydrochloride) is used to investigate enzyme activity, metabolic flux, and pathway regulation, particularly in studies focused on polyamine catabolism and its link to malignancy, with observed biological effects typically occurring in the nanomolar to micromolar range depending on assay conditions. It is commonly applied in cell-based assays and translational research models to elucidate molecular mechanisms underlying cancer progression and to support biomarker validation, with concentrations and dosing regimens tailored to specific experimental objectives.
