Boosting NAD+ with a small molecule that activates NAMPT

Nature Communications, 2019
Nicotinamide phosphoribosyltransferase (NAMPT) catalyzes the rate determining step for NAD+ synthesis and is of interest as a drug target. Here the authors identify and characterize a small molecule NAMPT activator SBI-797812, elucidate its mode of ...

Inhibition of Phosphodiesterase 10A by MP‐10 Rescues Behavioral Deficits and Normalizes Microglial Morphology and Synaptic Pruning in A Mouse Model of FOXP1 Syndrome

Advanced Science, EarlyView.
We demonstrate that Foxp1± mice, modeling FOXP1 haploinsufficiency, exhibit behavioral deficits, striatal neuroinflammatory changes including altered microglial complexity and synaptic pruning, and markedly reduced Pde10a expression. Pde10a inhibition starting immediately after birth restores Foxp1± behavior, microglial morphology, and pruning ...

Adipocytes Promote Cisplatin Resistance through Secreting A1BG and Regulating NAMPT/PARP1 Axis‐Mediated DNA Repair in Osteosarcoma

Advanced Science, EarlyView.
The proposed working model for how adipocytes participate in cisplatin resistance in osteosarcoma. The adipocytes secret A1BG and stabilize NAMPT, leading to increased NAD⁺ levels and subsequent increased PARP1‐mediated DNA repair, resulting in cisplatin resistance in osteosarcoma finally.

Extracellular nicotinamide phosphoribosyltransferase: role in disease pathophysiology and as a biomarker

Frontiers in Immunology, 2023
Nicotinamide phosphoribosyltransferase (NAMPT) plays a central role in mammalian cell metabolism by contributing to nicotinamide adenine dinucleotide biosynthesis. However, NAMPT activity is not limited to the intracellular compartment, as once secreted,

The fate of thiopurine metabolites after switching to low‐dose thiopurine with allopurinol or thioguanine in IBD patients: A retrospective analysis

British Journal of Clinical Pharmacology, EarlyView.
Aims Shunting (hypermethylating) thiopurine metabolism, characterized by excessive 6‐MMPR production and (sub)therapeutic 6‐TGN levels, poses a significant challenge in the treatment of inflammatory bowel disease (IBD). This study evaluates the metabolic outcomes of switching to low‐dose thiopurine with allopurinol (LDTA) or thioguanine (TG) in IBD ...

NAMPT and NAPRT, Key Enzymes in NAD Salvage Synthesis Pathway, Are of Negative Prognostic Value in Colorectal Cancer

Frontiers in Oncology, 2019
Nicotinamide adenine dinucleotide (NAD) is a profoundly important cofactor in redox reactions. Nicotinamide phosphoribosyltransferase (NAMPT) and nicotinate phosphoribosyltransferase (NAPRT) are key enzymes for NAD salvage biosynthesis pathway, which ...

Human hypoxanthine-guanine phosphoribosyltransferase.

Journal of Biological Chemistry, 1983
A mutant form of human hypoxanthine-guanine phosphoribosyltransferase (HPRTToronto) was isolated from erythrocytes of a male patient with gout due to a partial deficiency of enzyme activity. The tryptic peptides of HPRTToronto were mapped by reverse-phase high pressure liquid chromatography in an attempt to define the precise abnormality in its primary

Association between Cigarette Smoking and Hypoxanthine Guanine Phosphoribosyltransferase Activity

Kaohsiung Journal of Medical Sciences, 2005
The aim of this study was to investigate the association between smoking behavior and hypoxanthine guanine phosphoribosyltransferase (HGPRT) activity. A cross-sectional study was performed of 82 men, including 38 non-smokers and 44 smokers.
