CHS-111 is a benzyl indazole compound that inhibits superoxide anion (O(2)(-)) generation and reduces fMLP-stimulated PLD activity (IC(50) 3.9±1.2μM). It inhibits the interaction of PLD1 with ADP-ribosylation factor (Arf) 6 and Ras homology (Rho) A, and reduces the membrane recruitment of RhoA in fMLP-stimulated cells.

cis-Resveratrol ((Z)-Resveratrol) has antiviral activity, inhibits enteroviruses, increases TyrRS, promotes histone serine-ADP ribosylation-dependent DNA repair, and provides neuroprotection in a TyrRS-dependent manner.

RBN-3143 is a potent inhibitor of NAD+-competitive catalytic PARP14 (IC50= 4 nM), which inhibits ADP-ribosylation mediated by PARP14 and stabilizes PARP14 in cell lines, demonstrating research potential for lung inflammation.

NADH disodium salt hydrate, also known as Disodium NADH hydrate, functions as an orally active reduced coenzyme. It serves as a donor of ADP-ribose units in ADP-ribosylation reactions and acts as a precursor to cyclic ADP-ribose. Additionally, it contributes to cellular energy metabolism by acting as a renewable electron donor in processes such as glycolysis, β-oxidation, and the tricarboxylic acid (TCA) cycle [1].

Guanylyl Imidodiphosphate trisodium (Guanosine 5'-[β,γ-imido]triphosphate), a non-hydrolysable GTP analogue, activates ADP-ribosylation factor (ARF) and strongly stimulates adenylate cyclase. It is utilized in protein synthesis studies [1] [2] [3].

AV-153 is a 1,4-dihydropyridine derivative with antimutagenic properties. It intercalates into DNA at single strand breaks, resulting in reduced DNA damage and stimulation of DNA repair in human cells in vitro. AV-153 also interacts with thymine and cytosine and influences poly(ADP)ribosylation. Moreover, AV-153 exhibits anti-cancer activity.

Glutamyl ribose 5-phosphate is obtained by the linkage region in ADP ribosylation of proteins.

β-Nicotinamide adenine dinucleotide reduced dipotassium is an orally active, reduced coenzyme that functions as a donor of ADP-ribose units in ADP-ribosylation reactions and as a precursor of cyclic ADP-ribose. It also serves as a regenerative electron donor in essential cellular energy metabolism processes, including glycolysis, β-oxidation, and the tricarboxylic acid (TCA) cycle [1].

K-756 is a direct and selective inhibitor of tankyrase (TNKS), inhibiting the ADP-ribosylation activity of TNKS1 [IC50 = 31 nM] and TNKS2 [IC50 = 36 nM].

AV-153 free base is a 1,4-dihydropyridine (1,4-DHP) derivative with antimutagenic and anti-cancer activity. It interacts with cytosine and thymine, influences poly(ADP)ribosylation, intercalates to DNA at single-strand breaks, reduces DNA damage, and stimulates DNA repair in human cells in vitro [1] [2] [3].

MC2050 is a potent PARP-1 inhibitor. The IC50 for inhibition of PARP-1 activity is 119 nM, compared to 1.8 μM for PARP-2. MC2050 inhibits apoptosis and blocks poly ADP-ribosylation of histone H1 in hydrogen peroxide treated SH-SY5Y neuroblastoma cells.

1-Palmitoyl-2-stearoyl-rac-glycerol, a diacylglycerol, features palmitic acid at the sn-1 position and stearic acid at the sn-2 position. This compound plays a role in identifying the fatty acyl chain properties of diacylglycerols that activate the ADP-ribosylation factor 1 GTPase-activating protein (ARF1 GAP).

M-COPA is a golgi disruptor which inhibits cell surface expression of MET protein and the ADP-ribosylation factor 1 (Arf1) activation. M-COPA also inhibits angiogenesis through suppression of both VEGFR1 2 and nuclear factor-kappaB (NF-kappaB) signaling pathways.
