From Pharmacophore to Warhead: NAD+‐Targeting Triazoles as Mechanism‐Based Sirtuin Inhibitors

Angewandte Chemie, Volume 137, Issue 52, December 22, 2025.
We report “Sirtuin Trapping Ligands” (SirTraps), mechanism‐based 1,2,3‐triazole inhibitors that hijack sirtuin (SIRT) catalysis to form covalent triazolium– or triazole–ADP‐ribose (ADPR) adducts from NAD+. These trapped intermediates stall the enzyme in an inactive state, providing a biocompatible alternative to thiocarbonyl inhibitors and a blueprint ...

Targeting CD38/ ADP-ribosyl cyclase as a novel therapeutic strategy for identification of three potent agonists for leukopenia treatment

Pharmacological Research
Leukopenia is the most common side effect of chemotherapy and radiotherapy. It potentially deteriorates into a life-threatening complication in cancer patients.

Molsidomine inhibits the chemoattractant-induced respiratory burst in human neutrophils via a no-independent mechanism [PDF]

, 1992
3-Morpholino-sydnonimine (SIN-1) is a NO-releasing compound which mimics the effects of cGMP through activation of soluble guanylyl cyclase. Its prodrug, molsidomine (SIN-10), does not release NO but does modulate various cell functions.

Phenobarbital induces alterations in the proteome of hepatocytes and mesenchymal cells of rat livers. [PDF]

PLoS ONE, 2013
Preceding studies on the mode of action of non-genotoxic hepatocarcinogens (NGCs) have concentrated on alterations induced in hepatocytes (HCs). A potential role of non-parenchymal liver cells (NPCs) in NGC-driven hepatocarcinogenesis has been largely ...

One Single Nucleotide Polymorphism of the TRPM2 Channel Gene Identified as a Risk Factor in Bipolar Disorder Associates with Autism Spectrum Disorder in a Japanese Population

Diseases, 2020
The transient receptor potential melastatin 2 (TRPM2) is a non-specific cation channel, resulting in Ca2+ influx at warm temperatures from 34 °C to 47 °C, thus including the body temperature range in mammals.

Identification of bovine liver mitochondrial NAD+ glycohydrolase as ADP-ribosyl cyclase [PDF]

Biochemical Journal, 1997
The present investigation identifies bovine liver mitochondrial NADase (NAD+ glycohydrolase) as a member of the class of bifunctional ADP-ribosyl cyclases/cyclic ADP-ribose hydrolases, known to be potential second messenger enzymes. These enzymes catalyse the synthesis and degradation of cyclic ADP-ribose, a potent intracellular calcium-mobilizing ...

CD38/cADPR Signaling Pathway in Airway Disease: Regulatory Mechanisms

Mediators of Inflammation, 2018
Asthma is an inflammatory disease in which proinflammatory cytokines have a role in inducing abnormalities of airway smooth muscle function and in the development of airway hyperresponsiveness.

Anxiety- and depression-like behavior in mice lacking the CD157/BST1 gene, a risk factor for Parkinson’s disease

Frontiers in Behavioral Neuroscience, 2014
CD157, known as bone marrow stromal cell antigen-1, is a glycosylphosphatidylinositol-anchored ADP-ribosyl cyclase that supports the survival and function of B-lymphocytes and hematopoietic or intestinal stem cells. Although CD157/Bst1 is a risk locus in

NAD+‒circadian rhythm coupling in dementia

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...
