Abstract
Cancer immunotherapy has greatly improved the prognosis of tumor-bearing patients. Nevertheless, cancer patients exhibit low response rates to current immunotherapy drugs, such as PD1 and PDL1 antibodies. Cyclic dinucleotide analogs are a promising class of immunotherapeutic agents. In this study, in situ autologous tumor vaccines, composed of bis-2'-F-cGSASMP phosphonothioate isomers (FGA-di-pS-2 or FGA-di-pS-4) and cytidinyl/cationic lipids (Mix), were constructed. Intravenous and intratumoral injection of FGA-di-pS-2/Mix or FGA-di-pS-4/Mix enhanced the immunogenic cell death of tumor cells in vivo, leading to the exposure and presentation of whole tumor antigens, inhibiting tumor growth in both LLC and EO771 tumor in situ murine models and increasing their survival rates to 50% and 23%, respectively. Furthermore, the tumor-bearing mice after treatment showed potent immune memory efficacy and exhibited 100% protection against tumor rechallenge. Intravenous administration of FGA-di-pS-2/Mix potently promoted DC maturation, M1 macrophage polarization and CD8+ T cell activation and decreased the proportion of Treg cells in the tumor microenvironment. Notably, two doses of ICD-debris (generated by FGA-di-pS-2 or 4/Mix-treated LLC cells) protected 100% of mice from tumor growth. These tumor vaccines showed promising results and may serve as personalized cancer vaccinations in the future.

Abstract
We demonstrate the use of the symmetrical diethyl(dimethyl)difluoromethylene bisphosphonate reagent for the synthesis of terminal and unsymmetrical difluoromethylene bisphosphonates, close analogues of biologically important molecules. The difference in reactivity of the methyl and ethyl groups in the symmetrical diethyl(dimthyl)difluoromethylene bisphosphonate is exploited in a stepwise demethylation-condensation sequence to functionalize either side of the reagent to allow the generation of a series of close bioisosteres of natural pyrophosphate molecules, including ADPr, CDP-glycerol and CDP-ribitol.

Abstract
ADP-ribosylation is an important post-translational modification that plays a pivotal role in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis. Although chemical synthesis of mono- or poly-ADP-ribosylated biomolecules is extremely difficult due to the challenges in regio- and stereoselective glycosylation, suitable protective group manipulations and pyrophosphate construction, synthetic procedures towards these bio-related targets have been reported in recent years. Chemically synthesized well-defined ADP-ribose derivatives serve as useful tools in biological experiments aimed to further elucidate native ADP-ribosylation. In this review, we will discuss the synthetic studies on mono-ADP-ribosylated proteins and oligo-ADP-ribose chains. Future possible synthetic targets and upcoming new methods for the synthesis of these molecules are also included.

Abstract
Herein, we report on the synthesis of a small set of linear precursors of an inosine analogue of cyclic ADP-ribose (cADPR), a second messenger involved in Ca2+ mobilization from ryanodine receptor stores firstly isolated from sea urchin eggs extracts. The synthesized compounds were obtained starting from inosine and are characterized by an N1-alkyl chain replacing the "northern" ribose and a phosphate group attached at the end of the N1-alkyl chain and/or 5'-sugar positions. Preliminary Ca2+ mobilization assays, performed on differentiated C2C12 cells, are reported as well.

Abstract
Cyclic adenosine diphosphate ribose (cADPR) is an endogenous Ca2+ mobilizer involved in diverse cellular processes. Mimics of cADPR play a crucial role in investigating the molecular mechanism(s) of cADPR-mediated signaling. Here, compound 3, a mimic of cADPR in which a neutral triazole moiety and an ether linkage were introduced to substitute the pyrophosphate and "northern" ribose components, respectively, was synthesized for the first time. The pharmacological activities in Jurkat cells indicated that this mimic is capable of penetrating plasma membrane and inciting Ca2+ release from the endoplasmic reticulum (ER) through the action of ryanodine receptors (RyRs) and triggering Ca2+ influx. Furthermore, a uridine moiety was introduced in place of adenine and the new cADPR mimics 4 and 5 were synthesized. The results of biological investigation showed that these mimics also targeted RyRs and retained moderate Ca2+ agonistic activities. The results indicated that the neutral cADPR mimics had the same targets for inducing Ca2+ signaling.

Abstract
Cyclic adenosine 5'-diphosphate ribose (cADPR) is a ubiquitous Ca2+-releasing second messenger. Knowledge of its conformational landscape is an essential tool for unraveling the structure-activity relationship (SAR) in cADPR. Variable-temperature 1H NMR spectroscopy, in conjunction with PSEUROT and population analyses, allowed us to determine the conformations and thermodynamic parameters of the furanose rings, γ-bonds (C4'-C5'), and β-bonds (C5'-O5') in the cADPR analogues 2'-deoxy-cADPR, 7-deaza-cADPR, and 8-bromo-cADPR. A significant finding was that, although the analogues are similar to each other and to cADPR itself in terms of overall conformation and population (ΔG°), there were subtle yet important differences in some of thermodynamic properties (ΔH°, ΔS°) associated with each of the conformational equilibria. These differences prompted us to propose a model for cADPR in which the interactions between the A2'-N3, A5″-N3, and H2-R5' atoms serve to fine-tune the N-glycosidic torsion angles (χ).

Abstract
Cyclic N1-pentylinosine monophosphate (cpIMP), a novel simplified inosine derivative of cyclic ADP-ribose (cADPR) in which the N1-pentyl chain and the monophosphate group replace the northern ribose and the pyrophosphate moieties, respectively, was synthesized. The role played by the position of the phosphate group in the key cyclization step, which consists in the formation of a phosphodiester bond, was thoroughly investigated. We have also examined the influence of the phosphate bridge on the ability of cpIMP to mobilize Ca2+ in PC12 neuronal cells in comparison with the pyrophosphate bridge present in the cyclic N1-pentylinosine diphosphate analogue (cpIDP) previously synthesized in our laboratories. The preliminary biological tests indicated that cpIMP and cpIDP induce a rapid increase of intracellular Ca2+ concentration in PC12 neuronal cells.

Abstract
Currently, there is an ongoing interest in the synthesis of nucleoside diphosphate analogs as important regulators in catabolism/anabolism, and their potential applications as mechanistic probes and chemical tools for bioassays. However, the pyrophosphate bond formation step remains as the bottleneck. In this Digest, the chemical synthesis of the pyrophosphate bonds of representative bioactive nucleoside diphosphate analogs, i.e. phosphorus-modified analogs, nucleoside cyclic diphosphates, and nucleoside diphosphate conjugates, will be described.

Abstract
Cyclic adenosine 5'-diphosphate ribose (cADPR) is a second messenger in the Ca(2+) signaling pathway. To elucidate its molecular mechanism in calcium release, a series of cADPR analogues with modification on ribose, nucleobase, and pyrophosphate have been investigated. Among them, the analogue with the modification of the northern ribose by ether linkage substitution (cIDPRE) exhibits membrane-permeate Ca(2+) agonistic activity in intact HeLa cells, human T cells, mouse cardiac myocytes and neurosecretory PC12 cell lines; thus, cIDPRE and coumarin-caged cIDPRE are valuable probes to investigate the cADPR-mediated Ca(2+) signal pathway.

Abstract
Analogues of the potent Ca(2+) releasing second messenger cyclic ADP-ribose (cADPR) with a 1,2,3-triazole pyrophosphate bioisostere were synthesised by click-mediated macrocyclisation. The ability to activate Ca(2+) release was surprisingly retained, and hydrolysis of cADPR by CD38 could also be inhibited, illustrating the potential of this approach to design drug-like signalling pathway modulators.

Abstract
We have investigated the applicability of different chemical methods for pyrophosphate bond formation to the synthesis of 5-substituted UDP-galactose and UDP-N-acetylglucosamine derivatives. The use of phosphoromorpholidate chemistry, in conjunction with N-methyl imidazolium chloride as the promoter, was identified as the most reliable synthetic protocol for the preparation of these non-natural sugar-nucleotides. Under these conditions, the primary synthetic targets 5-iodo UDP-galactose and 5-iodo UDP-N-acetylglucosamine were consistently obtained in isolated yields of 40-43%. Both 5-iodo UDP-sugars were used successfully as substrates in the Suzuki-Miyaura cross-coupling with 5-formylthien-2-ylboronic acid under aqueous conditions. Importantly, 5-iodo UDP-GlcNAc and 5-(5-formylthien-2-yl) UDP-GlcNAc showed moderate inhibitory activity against the GlcNAc transferase GnT-V, providing the first examples for the inhibition of a GlcNAc transferase by a base-modified donor analogue.

Abstract
Cyclic adenosine diphosphate ribose is an endogenous Ca2+ mobilizer involved in diverse cellular processes. A cell membrane-permeable cyclic adenosine diphosphate ribose analogue, cyclic inosine diphosphoribose ether (cIDPRE), can induce Ca2+ increase in intact human Jurkat T-lymphocytes. Here we synthesized a coumarin-caged analogue of cIDPRE (Co-i-cIDPRE), aiming to have a precisely temporal and spatial control of bioactive cIDPRE release inside the cell using UV uncaging. We showed that Co-i-cIDPRE accumulated inside Jurkat cells quickly and efficiently. Uncaging of Co-i-cIDPRE evoked Ca2+ release from endoplasmic reticulum, with concomitant Ca2+ influx in Jurkat cells. Ca2+ release evoked by uncaged Co-i-cIDPRE was blocked by knockdown of ryanodine receptors (RyRs) 2 and 3 in Jurkat cells. The associated Ca2+ influx, on the other hand, was abolished by double knockdown of Stim1 and TRPM2 in Jurkat cells. Furthermore, Ca2+ release or influx evoked by uncaged Co-i-cIDPRE was recapitulated in HEK293 cells that overexpress RyRs or TRPM2, respectively, but not in wild-type cells lacking these channels. In summary, our results indicate that uncaging of Co-i-cIDPRE incites Ca2+ release from endoplasmic reticulum via RyRs and triggers Ca2+ influx via TRPM2.

Abstract
Novel cADPR mimics, which integrate nucleobase, northern and southern ribose modifications were synthesized. The key steps of the synthesis were a Cu(I)-catalyzed Hüisgen [3+2] cycloaddition and a microwave-assisted intramolecular pyrophosphorylation. Preliminary biological investigations showed that these cADPR mimics are membrane-permeating agonists of the calcium signaling pathway. The introduction of chlorine or fluorine at the 2'-position of the southern riboses led to a decrease of activity. The existence of a hydrophobic group on the 3'-OH of the southern riboses does not obviously alter the agonistic activity.
