Discovery of potential visfatin activators using in silico docking and ADME predictions as therapy for type 2 diabetes

Beni-Suef University Journal of Basic and Applied Sciences, 2018
Visfatin (Nicotinamide phosphoribosyltransferase) is an adipokine implicated in mediating insulin resistance and exhibiting insulin mimetic effect and therefore represents a druggable target for diabetes therapy.

Nicotinamide phosphoribosyltransferase may be involved in age-related brain diseases. [PDF]

PLoS ONE, 2012
Nicotinamide phosphoribosyltransferase (NAMPT) is a key enzyme for nicotinamide adenine dinucleotide (NAD) biosynthesis, and can be found either intracellularly (iNAMPT) or extracellularly (eNAMPT).

The Efficacy of Risk Factor Modification Compared to NAD+ Repletion in Diastolic Heart Failure

JACC: Basic to Translational Science
Summary: Heart failure (HF) with left ventricular diastolic dysfunction is a growing global concern. This study evaluated myocardial oxidized nicotinamide adenine dinucleotide (NAD+) levels in human systolic and diastolic HF and in a murine model of HF ...

Maintenance of NAD+ Homeostasis in Skeletal Muscle during Aging and Exercise

Cells, 2022
Nicotinamide adenine dinucleotide (NAD) is a versatile chemical compound serving as a coenzyme in metabolic pathways and as a substrate to support the enzymatic functions of sirtuins (SIRTs), poly (ADP-ribose) polymerase-1 (PARP-1), and cyclic ADP ribose

Rhoifolin Alleviates Ulcerative Colitis by Targeting NMNAT1 and Activating SIRT1‐FOXO1 Signaling to Enhance ILC3s Effector Function

Advanced Science, EarlyView.
Rhoifolin directly targets NMNAT1, thereby activating nicotinamide salvage pathway and promoting intracellular NAD+ biosynthesis. Elevated NAD+ levels enhance SIRT1 activity, leading to FOXO1 deacetylation and nuclear translocation. Nuclear FOXO1 subsequently binds to the IL‐22 promoter, upregulating IL‐22 transcription and potentiating ILC3 effector ...

Cancer cell metabolic plasticity allows resistance to NAMPT inhibition but invariably induces dependence on LDHA

Cancer & Metabolism, 2018
Background Inhibitors of nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in NAD+ biosynthesis from nicotinamide, exhibit anticancer effects in preclinical models.

Porcine placental extract increase the cellular NAD levels in human epidermal keratinocytes

Scientific Reports, 2022
Nicotinamide adenine dinucleotide (NAD) is an essential cofactor for numerous enzymes involved in energy metabolism. Because decreasing NAD levels is a common hallmark of the aging process in various tissues and organs, maintaining NAD levels has ...

Nicotinamide Metabolism Constrains Memory CD8+ T Cell Formation Through a Putative HS1BP3‐SIRT1‐FOXO3‐BCL6 Axis

Advanced Science, EarlyView.
ABSTRACT Memory T cells exhibit long‐term persistence, a defining feature that underpins durable clinical responses to adoptive immunotherapies. The mechanisms that integrate metabolic cues with transcriptional control of memory fate remain undetermined. Here, we identify HS1‐binding protein 3 (HS1BP3) is preferentially expressed in memory CD8+ T cells.

Supplementation of Nicotinic Acid with NAMPT Inhibitors Results in Loss of In Vivo Efficacy in NAPRT1-Deficient Tumor Models

Neoplasia: An International Journal for Oncology Research, 2013
Nicotinamide adenine dinucleotide (NAD) is a metabolite essential for cell survival and generated de novo from tryptophan or recycled from nicotinamide (NAM) through the nicotinamide phosphoribosyltransferase (NAMPT)-dependent salvage pathway ...
