ADP‐ribosyl cyclase coupled with receptors via G proteins [PDF]

FEBS Letters, 1997
Crude cell membranes in mammalian cells contain ADP‐ribosyl cyclase, which converts NAD+ to cyclic ADP‐ribose. Acetylcholine either increases or inhibits this activity in NG108‐15 neuronal cells and adrenal chromaffin cells in a muscarinic receptor subtype‐specific manner.

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 ...

The human NAD metabolome: Functions, metabolism and compartmentalization [PDF]

, 2015
The metabolism of NAD has emerged as a key regulator of cellular and organismal homeostasis. Being a major component of both bioenergetic and signaling pathways, the molecule is ideally suited to regulate metabolism and major cellular events.

CD157 signaling promotes survival of acute myeloid leukemia cells and modulates sensitivity to cytarabine through regulation of anti-apoptotic Mcl-1

Scientific Reports, 2021
CD157/BST-1 (a member of the ADP-ribosyl cyclase family) is expressed at variable levels in 97% of patients with acute myeloid leukemia (AML), and is currently under investigation as a target for antibody-based immunotherapy. We used peripheral blood and

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 ...

EHMTI-0026. Neuroprolotherapy and acupuncture for clinical trial of acute and chronic migraine treatment [PDF]

, 2014
Nicotinic acid adenine dinucleotide phosphate (NAADP) and cyclic ADP-ribose (cADPR) are Ca2+-mobilizing messengers important for modulating cardiac excitation–contraction coupling and pathophysiology. CD38, which belongs to the ADP-ribosyl cyclase family,

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.

Impaired learning and memory in CD38 null mutant mice [PDF]

, 2016
CD38 is an enzyme that catalyzes the formation of cyclic ADP ribose and nicotinic acid adenine dinucleotide phosphate, both of which are involved in the mobilization of Ca2+ from intracellular stores.

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 ...
