COA of Formula: C10H11NOOn September 20, 2000 ,《Beckmann rearrangements of 1-indanone oxime derivatives using aluminum chloride and mechanistic considerations》 was published in Bulletin of the Korean Chemical Society. The article was written by Lee, Byoung Se; Chu, Soyoung; Lee, In Young; Lee, Bon-Su; Song, Choong Eui; Chi, Dae Yoon. The article contains the following contents:

Hydrocarbostyril, which is a key intermediate in a new synthetic route to 6-nitroquipazine, can be prepared from 1-indanone oxime by Beckmann rearrangement. The reaction was optimized to 91% yield by using a Lewis acid, AlCl3, instead of common acids such as polyphosphoric acid, and H2SO4 used in conventional Beckmann rearrangement (20% in the literature, 10% in the authors’ experiment). The optimized condition was established with 3 equiv AlCl3 in CH2Cl2 at -40° to room temperature for 40 min. These conditions were applied to other 1-indanone derivatives, such as 4-methyl-, 4-methoxy- and 4- and 6-nitro-1-indanones. The mechanism of this reaction was proposed on the basis of the effect of temperature and substituent on product ratio, with the aid of PM3 calculation for a model system.

Bellocchi, Daniele; Macchiarulo, Antonio; Costantino, Gabriele; Pellicciari, Roberto published an article on February 15 ,2005. The article was titled 《Docking studies on PARP-1 inhibitors: insights into the role of a binding pocket water molecule》, and you may find the article in Bioorganic & Medicinal Chemistry.Safety of 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one The information in the text is summarized as follows:

The binding mode of a series of competitive PARP-1 inhibitors was investigated employing a mol. docking approach by using Autodock 3.0. A particular attention was given to the role played by a water mol. present in some but not all the so far available crystal structures of the catalytic domain of PARP-1. Good correlation between calculated binding energies and exptl. inhibitory activities was obtained either by including (r2 = 0.87) or not (r2 = 0.84) the structural water mol. Closer inspection of our results suggested that this water mol. should be considered part of the hydration shell of polar inhibitors and not as a structural water.5-Methyl-3,4-dihydroisoquinolin-1(2H)-one(cas: 129075-56-5Safety of 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one) was used in this study.

Name: 5-Methyl-3,4-dihydroisoquinolin-1(2H)-oneOn November 8, 2001 ,《Modeling of Poly(ADP-ribose)polymerase (PARP) Inhibitors. Docking of Ligands and Quantitative Structure-Activity Relationship Analysis》 appeared in Journal of Medicinal Chemistry. The author of the article were Costantino, Gabriele; Macchiarulo, Antonio; Camaioni, Emidio; Pellicciari, Roberto. The article conveys some information:

Poly(ADP-ribose)polymerase-1 (PARP-1) is a nuclear enzyme that has recently emerged as an important player in the mechanisms leading to postischemic neuronal death, and PARP inhibitors have been proposed as potential neuroprotective agents. With the aim of clarifying the structural basis responsible for PARP inhibition, the authors carried out a computational study on 46 inhibitors available through the literature. Our computational approach is composed of three parts. In the first one, representative PARP inhibitors have been docked into the crystallog. structure of the catalytic domain of PARP by using the Autodock 2.4 program. The docking studies thus carried out have provided an alignment scheme that has been instrumental for superimposing all the remaining inhibitors. Upon the basis of this alignment scheme, a quant. structure-activity relation (QSAR) anal. has been carried out after electrostatic and steric interaction energies have been computed with the RECEPTOR program. The QSAR anal. yielded a predictive model able to explain much of the variance of the 46-compound data set. The inspection of the QSAR coefficients revealed that the major driving force for potent inhibition is given by the extension of the contact surface between enzyme and inhibitors while electrostatic energy and hydrogen bonding capability play a minor role. Finally, the projection of the QSAR coefficients back onto the x-ray structure of the catalytic domain of PARP provides insights into the role played by specific amino acid residues. This information will be useful to address the design of new selective and potent PARP inhibitors. In addition to this study using 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one, there are many other studies that have used 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one(cas: 129075-56-5Name: 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one) was used in this study.

Hilary; Curtin, Nicola J.; Newell, David R.; Pemberton, Louise C.; Golding, Bernard T. published their research in Journal of Medicinal Chemistry on December 17 ,1998. The article was titled 《Resistance-Modifying Agents. 5. Synthesis and Biological Properties of Quinazolinone Inhibitors of the DNA Repair Enzyme Poly(ADP-ribose) Polymerase (PARP)》.Related Products of 129075-56-5 The article contains the following contents:

Clin. studies concerning the role of poly(ADP-ribose) polymerase (PARP) in the repair of drug- and radiation-induced DNA damage have been impeded by the poor solubility, lack of potency, and limited specificity of currently available inhibitors. A series of 2-alkyl- and 2-aryl-substituted 8-hydroxy-, 8-methoxy-, and 8-methylquinazolin-4(3H)-ones has been synthesized and evaluated for PARP inhibitory activity in permeabilized L1210 murine leukemia cells. 8-Methoxy- and 8-methylquinazolinones (14-34) were readily prepared by acylation of 3-substituted anthranilamides with the appropriate acid chloride, followed by base-catalyzed cyclization. The requisite 8-hydroxyquinazolinones (6, 35-39) were synthesized by demethylation of the corresponding 8-methoxyquinazolinones with BBr3. N-Methylation of 8-methoxy-2-methylquinazolinone (15) with MeI, followed by O-demethylation by BBr3, afforded the control N3-methylquinazolinones 42 and 43, resp. In general, an 8-hydroxy or 8-Me substituent enhanced inhibitory activity in comparison with an 8-methoxy group. 2-Phenylquinazolinones were marginally less potent than the corresponding 2-methylquinazolinones, but the introduction of an electron-withdrawing or electron-donating 4′-substituent on the 2-aryl ring invariably increased potency. This was particularly evident in the 8-methylquinazolinone series (IC50 values 0.13-0.27 μM), which are among the most potent PARP inhibitors reported to date. N3-Methylquinazolinones 42 and 43 were essentially devoid of activity (IC50 values > 100 μM). In studies with L1210 cells in vitro, a concentration of 200 μM 8-hydroxy-2-methylquinazolinone (6, NU1025) (IC50 value 0.40 μM) potentiated the cytotoxicity of the monomethylating agent 5-(3-methyltriazen-1-yl)imidazole-4-carboxamide and γ-radiation 3.5- and 1.4-fold, resp., at the 10% survival level. The experimental part of the paper was very detailed, including the reaction process of 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one(cas: 129075-56-5Related Products of 129075-56-5)

Morgan, Rory K.; Kirby, Ilsa T.; Vermehren-Schmaedick, Anke; Rodriguez, Kelsie; Cohen, Michael S. published an article on January 10 ,2019. The article was titled 《Rational Design of Cell-Active Inhibitors of PARP10》, and you may find the article in ACS Medicinal Chemistry Letters.Related Products of 129075-56-5 The information in the text is summarized as follows:

Poly-ADP-ribose polymerases (PARPs 1-16) have emerged as major regulators of diverse cellular processes. PARPs can be subclassified based on their ability to catalyze poly-ADP-ribosylation (PARylation) or mono-ADP-ribosylation (MARylation). While much is known about the cellular roles of PARPs that catalyze PARylation (e.g., PARP1), the function of PARPs that catalyze MARylation (e.g., PARP10) is substantially less understood. This is due in large part to the lack of small-mol. inhibitors that are selective for individual PARP family members that catalyze MARylation. Herein, we describe the rational design and synthesis of selective inhibitors of PARP10. Using structure-based design, we targeted a hydrophobic subpocket within the nicotinamide-binding site of PARP10. We synthesized a series of small mols. based on a 3,4-dihydroisoquinolin-1(2H)-one (dq, 1) scaffold that contain various substituents at the C-5 and C-6 positions designed to exploit this hydrophobic subpocket. We found a dq analog (22) that contains a Me group at the C-5 position and a substituted pyridine at the C-6 position that exhibits >10-fold selectivity for PARP10 over a large subset of other PARP family members. The results of this study will serve as a platform for future small-mol. probe development for PARP10 and other PARP family members that catalyze MARylation. In the part of experimental materials, we found many familiar compounds, such as 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one(cas: 129075-56-5Related Products of 129075-56-5)

Yau, Lorraine; Litchie, Brenda; Thomas, Shawn; Storie, Benjamin; Yurkova, Natalia; Zahradka, Peter published an article on January 31 ,2003. The article was titled 《Endogenous mono-ADP-ribosylation mediates smooth muscle cell proliferation and migration via protein kinase N-dependent induction of c-fos expression》, and you may find the article in European Journal of Biochemistry.Electric Literature of C10H11NO The information in the text is summarized as follows:

ADP-ribosylation has been coupled to intracellular events associated with smooth muscle cell vasoreactivity, cytoskeletal integrity and free radical damage. Addnl., there is evidence that ADP-ribosylation is required for smooth muscle cell proliferation. Our investigation employed selective inhibitors to establish that mono-ADP-ribosylation and not poly(ADP-ribosyl)ation was necessary for the stimulation of DNA synthesis by mitogens. Mitogen treatment increased concomitantly the activity of both soluble and particulate mono-ADP-ribosyltransferase, as well as the number of modified proteins. Inclusion of meta-iodobenzylguanidine (MIBG), a selective decoy substrate of arginine-dependent mono-ADP-ribosylation, prevented the modification of these proteins. MIBG also blocked the stimulation of DNA and RNA synthesis, prevented smooth muscle cell migration and suppressed the induction of c-fos and c-myc gene expression. An examination of relevant signal transduction pathways showed that MIBG did not interfere with MAP kinase and phosphatidylinositol 3-kinase stimulation; however, it did inhibit phosphorylation of the Rho effector, PRK1/2. This novel observation suggests that mono-ADP-ribosylation participates in a Rho-dependent signalling pathway that is required for immediate early gene expression.

Clayson, Edward T.; Kelly, Susan A.; Meier, Henry L. published an article in Cell Biology and Toxicology. The title of the article was 《Effects of specific inhibitors of cellular functions on sulfur mustard-induced cell death》.SDS of cas: 129075-56-5 The author mentioned the following in the article:

This study was conducted to determine whether inhibitors of normal cellular functions can reduce cytotoxicity induced by sulfur mustard (HD). The compounds examined include inhibitors of poly(ADP-ribose) polymerase (PADPRP), inhibitors of mono(ADP-ribose) transferase (MADPRT), inhibitors of lipid peroxidation, and an inhibitor of protein synthesis. To determine the effects of these compounds on HD-induced cell death, human lymphocyte preparations were treated with known concentrations (0.1 μM to 1000 μM) of an inhibitor and exposed to an estimated 87% effect concentration (EC87) of HD (170 μM) for loss in cell viability. Cell viability was determined at 24-26 h post-exposure to HD using a dye (propidium iodide) exclusion assay and a flow cytometer. All of the selected PADPRP inhibitors were found to be effective at reducing the cytotoxic effects of HD. These inhibitors were rank-ordered based on the concentration that gives 50% (EC50) reduction of HD-induced cell death. A significant correlation was observed between the compounds’ ability to inhibit PADPRP and the compounds’ ability to reduce HD- induced cell death, suggesting that PADPRP plays a role in HD-induced cell death. Inhibitors of MADPRT, lipid peroxidation, and protein synthesis were not effective at reducing HD-induced cell death.

《Repression of phosphoenolpyruvate carboxykinase gene activity by insulin is blocked by 3-aminobenzamide but not by PD128763, a selective inhibitor of poly(ADP-ribose) polymerase》 was written by Yau, Lorraine; Elliot, Tracy; Lalonde, Chantal; Zahradka, Peter. SDS of cas: 129075-56-5 And the article was included in European Journal of Biochemistry on April 1 ,1998. The article conveys some information:

Expression of the phosphoenolpyruvate carboxykinase (PEPCK) gene is induced by 3-aminobenzamide, an inhibitor of poly(ADP-ribose) polymerase. Synthesis of PEPCK mRNA is repressed by insulin, but remains detectable in H4IIE hepatoma cells exposed simultaneously to both 3-aminobenzamide and insulin. This capability of 3-aminobenzamide to block the inhibitory actions of insulin suggests that ADP-ribosylation is required for the regulation of PEPCK gene expression by insulin. Furthermore, neither changes in chromatin condensation nor cell growth status were linked to these events. The inability of 3,4-dihydro-5-methylisoquinolinone (PD128763), a selective inhibitor of poly(ADP-ribose) polymerase, to impede insulin-dependent repression of PEPCK gene expression, however, indicated that 3-aminobenzamide does not operate by inhibiting poly(ADP-ribosyl)ation. The potential involvement of mono(ADP-ribosyl)ation, a process that is also inhibited by 3-aminobenzamide, in the regulation of PEPCK gene activity was then evaluated. Anal. of poly(ADP-ribose) polymerase activity and poly(ADP-ribosyl)ation confirmed that there were no significant changes in response to insulin, while microsomal mono(ADP-ribosyl) transferase activity was elevated approx. fourfold. An increase in protein hydroxylamine-sensitive mono(ADP-ribosyl)ation was observed following insulin treatment. fhe sensitivity of the mono(ADP-ribosyl) transferase activity to 3-aminobenzamide but not PD128763 makes it plausible that mono(ADP-ribosyl)ation rather than poly(ADP-ribosyl)ation contributes to the regulation of PEPCK gene expression.

Forli, Stefano; Olson, Arthur J. published an article on January 26 ,2012. The article was titled 《A Force Field with Discrete Displaceable Waters and Desolvation Entropy for Hydrated Ligand Docking》, and you may find the article in Journal of Medicinal Chemistry.Synthetic Route of C10H11NO The information in the text is summarized as follows:

In modeling ligand-protein interactions, the representation and role of water are of great importance. We introduce a force field and hydration docking method that enables the automated prediction of waters mediating the binding of ligands with target proteins. The method presumes no prior knowledge of the apo or holo protein hydration state and is potentially useful in the process of structure-based drug discovery. The hydration force field accounts for the entropic and enthalpic contributions of discrete waters to ligand binding, improving energy estimation accuracy and docking performance. The force field has been calibrated and validated on a total of 417 complexes (197 training set; 220 test set), then tested in cross-docking experiments, for a total of 1649 ligand-protein complexes evaluated. The method is computationally efficient and was used to model up to 35 waters during docking. The method was implemented and tested using unaltered AutoDock4 with new force field tables. In addition to this study using 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one, there are many other studies that have used 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one(cas: 129075-56-5Synthetic Route of C10H11NO) was used in this study.

Stiefl, Nikolaus; Baumann, Knut published an article in Journal of Chemical Information and Modeling. The title of the article was 《Structure-Based Validation of the 3D-QSAR Technique MaP》.Application In Synthesis of 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one The author mentioned the following in the article:

For three target proteins with different binding pocket characteristics (size and shape, hydrophobicity, hydrogen-bonding) a structure-based validation of the translationally and rotationally invariant 3D-QSAR technique MaP is performed (MaP: Mapping Property distributions of mol. surfaces). The structure-based validation procedure comprises two steps: first, QSAR models are derived without using the information of the target protein. Second, the models are back-projected into the crystal structure of the binding pockets and interpreted. It is demonstrated that MaP is able to identify characteristics important for ligand binding in the cases studied here. Moreover, it is demonstrated that MaP is a versatile 3D-QSAR technique since good, predictive models could be obtained for all three data sets showing distinct characteristics.
