N2 - Two nicotinamide adenine dinucleotide (NAD +) analogues modified at the 6 position of the purine ring were synthesized, and their substrate properties toward Aplysia californica ADP-ribosyl cyclase were investigated. 6-N-Methyl NAD + (6-N-methyl nicotinamide adenosine 5′-dinucleotide 10) hydrolyzes to give the linear 6-N-methyl ADPR (adenosine 5′-diphosphoribose, 11), whereas 6-thio NHD + (nicotinamide 6-mercaptopurine 5′-dinucleotide, 17) generates a cyclic dinucleotide. Surprisingly, NMR correlation spectra confirm this compound to be the N1 cyclic product 6-thio N1-cIDPR (6-thio cyclic inosine 5′-diphosphoribose, 3), although the corresponding 6-oxo ...

Several combinations of the average chain length of the fractionating materials and the average pore diameter of the gels were examined to improve fractionation resolution. The gels with the average pore diameter near the average chain length resulted in high fractionation resolution. Single crystals of the fractionated and unfractionated PBZTs were observed by TEM. Both single crystals were fundamentally composed of rod crystals with the chain orienting normal to the rods. The unfractionated PBZT made a cluster of parallel rod crystals, where longer chains penetrated a few ...

Treatments with Poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors have offered patients carrying cancers with mutated BRCA1 or BRCA2 genes a new and in many cases effective option for disease control. There is potentially a large patient population that may also benefit from PARP inhibitor treatment, either in monotherapy or in combination with chemotherapy. Here, we describe the multifaceted role of PARP inhibitors and discuss which treatment options could potentially be useful to gain disease control without potentiating side effects.

Abstract: Poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors have shown clinical activity in epithelial ovarian cancer, leading both the US Food and Drug Administration (FDA) and the European Medicines Agency to approve olaparib for tumors characterized by BRCA1 and BRCA2 mutations. However, it is becoming increasingly evident that tumors that share molecular features with BRCA-mutant tumors-a concept known as BRCAness-also may exhibit defective homologous recombination DNA repair, and therefore will respond to PARP inhibition. A number of strategies have been proposed to identify BRCAness, including identifying defects in other genes that modulate homologous recombination and characterizing the mutational and transcriptional signatures of BRCAness. In addition to olaparib, a number of other PARP inhibitors are in clinical development. This article reviews the development of PARP inhibitors other than olaparib, and discusses the evidence for PARP inhibitors beyond BRCA1/2-mutant ...
The abundant nuclear enzyme PARP3 (EC 2.4.2.30) is a 116-kDa enzyme that comprises an NH2-terminal DNA-binding domain containing two zinc fingers that recognize DNA strand breaks, an automodification domain, and a COOH-terminal catalytic domain. PARP is activated by DNA strand breaks, and uses the ADP-ribose moiety of NAD+ as substrate to synthesize long homopolymers of ADP-ribose on nuclear proteins. PARP itself is the main protein acceptor (automodification), but the enzyme has also been shown to modify histones, high mobility group proteins, topoisomerases, DNA polymerases, and ligases (reviewed in Refs. 1, 2, 3 ). The ADP-ribose polymers formed by PARP are degraded by poly(ADP-ribose) glycohydrolase (4) , and after activation of PARP by DNA damage, the very rapid synthesis and degradation of ADP-ribose polymers that occurs can result in severe NAD+ depletion (5) .. PARP activation after DNA damage has pleiotropic functions, including mediation of DNA repair (e.g., Refs. 6 and 7 ), modulation ...
article{1cb77357-aca8-4b11-9d70-6a2e46c89bc9, abstract = {We report the association of an inherited variant located upstream of the poly(adenosine diphosphate-ribose) polymerase 1 (PARP1) gene (rs2249844), with survival in 11 BioGenoMEL melanoma cohorts. The gene encodes a protein involved in a number of cellular processes including single-strand DNA repair. Survival analysis was conducted for each cohort using proportional hazards regression adjusting for factors known to be associated with survival. Survival was measured as overall survival (OS) and, where available, melanoma-specific survival (MSS). Results were combined using random effects meta-analysis. Evidence for a role of the PARP1 protein in melanoma ulceration and survival was investigated by testing gene expression levels taken from formalin-fixed paraffin-embedded tumors. A significant association was seen for inheritance of the rarer variant of PARP1, rs2249844 with OS (hazard ratio (HR) = 1.16 per allele, 95% confidence interval ...
The second recently approved drug is olaparib, which is indicated as monotherapy for women who have germline BRCA mutations and have been treated with 3 or more lines of previous chemotherapy. Olaparib is an inhibitor of the enzyme poly(adenosine diphosphate-ribose) polymerase (PARP). Approval in December 2014 was based on a trial by Kaufman and colleagues that included patients with ovarian cancer and germline BRCA mutations. The final publication included 193 patients with a median of 4 prior regimens; all were considered platinum resistant or not suitable for further platinum therapy. Using single-agent olaparib, the response rate was 31% with a 225-day median duration of response. Generally, toxicities were mild to moderate and included fatigue, nausea and vomiting, and anemia. One concern about olaparib is the potentially increased rate of myelodysplastic syndrome and acute myeloid leukemia (2% in this trial).. H&O Are there any more angiogenesis inhibitors in current or recent clinical ...

Keywords: Tumor cell intrusion, Cell migration, HGF, Microtubules, Polarity indicators, Tankyrase Background In the last 10 years two digestive enzymes owed to the poly(adenosine diphosphate)-ribose polymerase (PARP) superfamily, tankyrase 1 (TNKS) and 2 (TNKS2), had been determined as crucial government bodies of spindle rod set up through poly(adenosine diphosphate)-ribosylation (PARsylation) of many microtubule-related protein within the spindle equipment [1, 2]. Poly (adenosine diphosphate)-ribose (PAR) devices possess also been certified as essential spindle constituents, with TNKS and TNKS2 (TNKS/2 hereinafter) becoming the excellent government bodies of spindle-associated PAR activity [3]. TNKS/2 downregulation can be regularly reported to produce extravagant mitotic phenotypes, including microtubule problems and supernumerary spindles [4]. TNKS/2 are also needed for appropriate sibling telomere quality [5] and centrosome function [6, 7]. Completely, these findings added to the archetypal ...

A combined two-step high-performance liquid chromatographic (HPLC) method was developed for the analysis of endogenous levels of cyclic adenosine diphosphoribose (cADPR) in cell extracts. The detection sensitivity for cADPR was about 10 pmol. Linearity of the HPLC detection system was demonstrated in the range of 10 pmol up to 2 nmol. The method was validated in terms of within-day and between-day reproducibility of retention times and peak areas of standard nucleotides. The method was applied to the analysis of endogenous cADPR in human T cell lines. Sequential separation of perchloric acid extracts from cells on strong anion-exchange and reversed-phase ion-pair HPLC resulted in a single symmetrical peak co-eluting with standard cADPR. The identity of this endogenous material was further confirmed by its ability to be converted to ADPR upon heating the cell samples at 80 degrees C for 2 h. Recoveries of the combined perchloric acid extraction-HPLC analysis procedures were 48.3 +/- 10.2%. The determined
Rationale: TRPM2 (Transient Receptor Potential Melastatin-2) expressed in endothelial cells (ECs) is a cation channel mediating Ca2+ entry in response to intracellular generation of adenosine diphosphoribose (ADPR), the TRPM2 ligand. Objective: Because polymorphonuclear leukocytes (PMN) interaction with endothelial cells (ECs) generates ROS, we addressed the possible role of TRPM2 expressed in ECs in the mechanism of transendothelial migration of PMNs. Methods and Results: We observed defective PMN transmigration in response to LPS challenge in adult mice in which the EC expressed TRPM2 is conditionally deleted (Trpm2iΔEC). PMN interaction with ECs induced the entry of Ca2+ in ECs via the EC-expressed TRPM2. Prevention of generation of ADPR in ECs significantly reduced Ca2+ entry in response to PMN activation of TRPM2 in ECs. PMNs isolated from gp91phox-/- mice significantly reduced Ca2+ entry in ECs via TRPM2 as compared to WT PMNs and failed to induce PMN transmigration. Overexpression of the ...
The rhamnolipid pathway in P. aeruginosa comprises three key enzymes and is based on the two precursors rhamnose and β-hydroxy-fatty acid (Fig. 1). The activated β-hydroxy-fatty acid hydroxyacyl-ACP is generated in the fatty acid de novo synthesis. Subsequently the first rhamnolipid specific enzyme 3-hydroxyacyl-ACP:3-hydroxyacyl-ACP O-3-hydroxy-acyl-transferase (RhlA) connects two hydroxyacyl-ACP molecules to form a dimer called hydroxyalkanoyloxy alkanoate (HAA). This molecule does not contain a rhamnose unit and thus is not a rhamnolipid. Due to its ester, carboxyl, and hydroxy groups and resulting amphiphilic structure, it nevertheless is a biosurfactant. The second precursor originates in six reactions from glucose. Activated dTDP-l-rhamnose is then fused by rhamnosyltransferase I (RhlB) to the HAA molecule to yield a mono-rhamnolipid. The second rhamnosyltransferase (RhlC) adds a second sugar to the mono-rhamnolipid, finally leading to the di-rhamnolipid biosurfactant.. The environmental ...
It is shown that an inorganic ionic polymer (sodium polyphosphate) exhibits the same type of glass transition temp. versus average chain length behavior as non-ionic organic polymers. If the chain ends resemble the terminal units, specifically in terms of the number of anions per phosphorus atom, the material is entirely analogous in its behavior to the organic materials, as shown, for instance, by the applicability of the Gibbs-DiMarzio theory. By contrast, if the terminal units possess two anions per phosphorus atom, a profound change in behavior is observed. (Author)(*INORGANIC POLYMERS

Poly(ADP-ribosyl)ation is a post-translational modification of proteins involved in regulation of many cellular pathways. Poly(ADP-ribose) (PAR) consists of chains of repeating ADP-ribose nucleotide units and is synthesized by the family of enzymes called poly(ADP-ribose) polymerases (PARPs). This modification can be removed by the hydrolytic action of poly(ADP-ribose) glycohydrolase (PARG) and ADP-ribosylhydrolase 3 (ARH3). Hydrolytic activity of macrodomain proteins (MacroD1, MacroD2 and TARG1) is responsible for the removal of terminal ADP-ribose unit and for complete reversion of protein ADP-ribosylation. Poly(ADP-ribosyl)ation is widely utilized in eukaryotes and PARPs are present in representatives from all six major eukaryotic supergroups, with only a small number of eukaryotic species that do not possess PARP genes. The last common ancestor of all eukaryotes possessed at least five types of PARP proteins that include both mono and poly(ADP-ribosyl) transferases. Distribution of PARGs strictly

BACKGROUND AND PURPOSE: Recently, a number of mimics of the second messenger cyclic ADP-ribose (cADPR) with replacement of adenosine by inosine were introduced. In addition, various alterations in the molecule ranging from substitutions at C8 of the base up to full replacement of the ribose moieties still retained biological activity. However, nothing is known about the metabolic stability and cellular effects of these novel analogues. EXPERIMENTAL APPROACH: cADPR and the inosine-based analogues were incubated with CD38, ADP-ribosyl cyclase and NAD-glycohydrolase and metabolism was analysed by RP-HPLC. Furthermore, the effect of the analogues on cytokine expression and proliferation was investigated in primary T-lymphocytes and T-lymphoma cells. KEY RESULTS: Incubation of cADPR with CD38 resulted in degradation to adenosine diphosphoribose. ADP-ribosyl cyclase weakly catabolised cADPR whereas NAD-glycohydrolase showed no such activity. In contrast, N1-cyclic inosine 5-diphosphoribose (N1-cIDPR) was not
Poly(ADP-ribose) polymerase activity in nuclei isolated from differentiating cardiac muscle of the rat has been characterized and its activity measured during development. Optimum enzyme activity is observed at pH 8.5. Poly(ADP-ribose) polymerase is inhibited by ATP, thymidine, nicotinamide, theophylline, 3-isobutyl-1-methylxanthine and caffeine and stimulated by actinomycin D. The activity measured under optimal assay conditions increases during differentiation of cardiac muscle and is inversely related to the rate of DNA synthesis and to the activities of DNA polymerase α and thymidine kinase. When DNA synthesis and the activity of DNA polymerase α are inhibited in cardiac muscle of the 1-day-old neonatal rat by dibutyryl cyclic AMP or isoproterenol, the specific activity of poly(ADP-ribose) polymerase measured in isolated nuclei is increased. The concentration of NAD+ in cardiac muscle increases during postnatal development. In the adult compared with the 1-day-old neonatal rat the ...
Nowadays it has become evident that a chronic systemic inflammation is present in patients suffering from chronic obstructive pulmonary disease (COPD).. The role of the nuclear enzyme poly(adenosine diphosphate-ribose)polymerase (PARP) as a key mediator within these systemic inflammatory processes as well as in COPD associated exercise intolerance and muscle weakness could recently been identified. The attenuating effect of dietary ingredients with PARP inhibiting activity on systemic inflammation was supported by data from in vitro and in vivo studies, from other groups as well as from our own lab. We identified several caffeine metabolites as potent inhibitors of the most abundant PARP-isoform PARP-1 in-vitro, in animal models as well as in ex-vivo experiments with whole blood from COPD patients.. However, clinical data with respect to their anti-inflammatory effects in COPD patients are currently not available for none of these substances. Therefore, the current clinical pilot study is ...
Trypanosomatids express complex glycoproteins and glycolipids that are often essential to their viability and virulence. In these parasites, sugar nucleotides are the sugar donors for protein and lipid glycosylation. But there had been no information on which sugar nucleotides are present in these parasites, and what their cellular concentrations might be. Daniel C. Turnock and Michael A.J. Ferguson of the University of Dundee, Scotland, United Kingdom, developed a new liquid chromatography/tandem mass spectrometry method to sensitively and selectively identify and measure sugar nucleotides in cell extracts.
TRPM2 is a Ca2+-permeable cation channel that is specifically activated by adenosine diphosphoribose (ADPR). Channel activation in the plasma membrane leads to Ca2+ influx and has been linked to apoptotic mechanisms. The primary agonist, ADPR, is produced both extra- and intracellularly and causes increases in intracellular calcium concentration ([Ca2+]i), but the mechanisms involved are not understood. Using short interfering RNA and a knockout mouse, we report that TRPM2, in addition to its role as a plasma membrane channel, also functions as a Ca2+-release channel activated by intracellular ADPR in a lysosomal compartment. We show that both functions of TRPM2 are critically linked to hydrogen peroxide-induced β cell death. Additionally, extracellular ADPR production by the ectoenzyme CD38 from its substrates NAD+ (nicotinamide adenine dinucleotide) or cADPR causes IP3-dependent Ca2+ release via P2Y and adenosine receptors. Thus, ADPR and TRPM2 represent multimodal signaling elements ...

The exosporium layer of Bacillus anthracis spores is rich in l-rhamnose, a common bacterial cell-wall component, which often contributes to the virulence of pathogens by increasing their adherence and immune evasion. The biosynthetic pathway used to form the activated l-rhamnose donor dTDP-l-rhamnose consists of four enzymes (RfbA, RfbB, RfbC and RfbD) and is an attractive drug target because there are no homologs in mammals. It was found that co-purifying and screening RfbC (dTDP-6-deoxy-d-xylo-4-hexulose 3,5-epimerase) from B. anthracis in the presence of the other three B. anthracis enzymes of the biosynthetic pathway y ...

An efficient and convenient synthetic route to glycosyl phosphites and phosphates has been developed that uses dibenzyl N,N-diethylphosphoramidite as a phosphitylating reagent. Glycosyl phosphites and phosphates of 2-acetamido-2-deoxy-D-galactose (GalNAc) (29), 2-acetamido-2-deoxy-D-glucose (GlcNAc) (30), D-galactose (Gal) (31), D-glucose (Glc) (32), D-mannose (Man) (33), L-rhamnose (Rha) (34), L-fucose (Fuc) (35), and N-acetylneuraminic acid (NeuAc) (41) were prepared by this procedure. Compounds 29 and 30 were obtained as α anomers exclusively, whereas compounds 31, 32, and 41 were obtained as β anomers, and compounds 33 and 34, as α anomers, predominately. The phosphates are useful for the synthesis of sugar nucleotides, and the phosphites are effective glycosylation reagents ...
