((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. Amides are not in general accessible by the direct condensation of amines with carboxylic acids for two reasons: first, both components are readily deactivated by a transfer of a proton from the acid to the amine and second, the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group. Nevertheless, the formation of five- and six-membered rings is often surprisingly simple provided that other factors can be brought into play to assist in the condensation.Application of 1094-61-7

Aging is referred to progressive dysfunction of body organs, including the brain. This study aims to explore the anti-aging effect of combing NMN (NMN) and lycopene (Lyco) (NMN + Lyco) on aging rats and senescent PC12 cells. Both in vivo and in vitro aging models were established using D-galactose (D-gal). The combination showed a trend to superiority over monotherapy in preventing aging in vivo and in vitro. Morris water maze test showed that NMN + Lyco effectively improved the ability of spatial location learning and memory of aging model rats. NMN + Lyco mitigated the oxidative stress of rat brains, livers, and PC12 cells by elevating the levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), GSH, as well as total antioxidant capacity (T-AOC), and reducing malondialdehyde (MDA) content. CCK-8 assay, senescence-associated β-galactosidase staining, and flow cytometer confirmed the cellular senescence of PC12 cells after exposing D-gal, and indicated the anti-senescence effect of NMN + Lyco in vitro. Moreover, NMN + Lyco effectively down-regulated the expressions of p53, p21, and p16 (senescence-related genes), and activated Keap1-Nrf2 signaling in both in vivo and in vitro aging models. In total, NMN + Lyco protected rats and PC12 cells from cognitive impairment and cellular senescence induced by D-gal, of which effects might be linked to the reduction of oxidative stress and the activation of Keap1-Nrf2 signaling. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Application of 1094-61-7).
