Spermidine (N-(3-Aminopropyl)-1,4-diaminobutane) inhibits NOS1 (nNOS). Spermidine binds and precipitates DNA and may be used for purification of DNA binding proteins. Spermidine activates PNK (polynucleotide kinase T4). Spermidine binds to and activates NMDA and has been shown to potentiate NMDA-induced currents in a concentration-dependent manner.

Spermidine-13C4 (Standard) is a reference standard of Spermidine-13C4 intended for quantitative analysis, quality control, and related biochemical research applications. Spermidine-13C4(hydrochloride) is a 13C-labeled version of spermidine (trihydrochloride). It helps maintain cell membrane stability, enhances antioxidant enzyme activity, and improves the function and gene expression related to photosystem II (PSII). Additionally, spermidine hydrochloride significantly reduces the levels of H2O2 and O2.-.

Spermidine-D6 (Standard) is a reference standard of Spermidine-D6 intended for quantitative analysis, quality control, and related biochemical research applications. Spermidine-d6 is a deuterated form of Spermidine. Spermidine is a natural polyamine present in ribosomes and living tissues, with functions in inflammation reduction, lipid metabolism regulation, and modulation of cell growth and death.

Spermidine-D (Standard) is a reference standard of Spermidine-D intended for quantitative analysis, quality control, and related biochemical research applications. Spermidine-d8(hydrochloride) is the deuterated form of Spermidine trihydrochloride. Spermidine hydrochloride helps maintain cell membrane stability, enhances the activity of antioxidant enzymes, and improves photosystem II (PSII) and related gene expression. It also significantly reduces the levels of H2O2 and O2.-.

Spermidine-D8 is the deuterated form of Spermidine (T4893) trihydrochloride. Spermidine (T4893) hydrochloride helps maintain cell membrane stability, enhances the activity of antioxidant enzymes, and improves photosystem II (PSII) and related gene expression. It also significantly reduces the levels of H2O2 and O2.-.

Spermidine trihydrochloride (Standard) is the reference standard of spermidine trihydrochloride, suitable for quantitative analysis, quality control, biochemical experiments and related research. Spermidine trihydrochloride (4-Azaoctamethylenediamine trihydrochloride) can maintain cell membrane stability, enhance the properties of antioxidant enzymes, improve photosystem II (PSII) and the expression of related genes, and also significantly reduce the levels of H₂O₂ and O₂·⁻.

Spermidine trihydrochloride (4-Azaoctamethylenediamine trihydrochloride), a natural polyamine, is a novel autophagy inducer and negatively modulates N-methyl-d-aspartate (NMDA).
