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.

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.

《Synthesis of 3,4-dihydro-1(2H)-isoquinolinones》 was written by Showalter, H. D. Hollis; Sercel, Anthony D.; Stier, Michael A.; Turner, William R.. Safety of 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one And the article was included in Journal of Heterocyclic Chemistry on August 31 ,2001. The article conveys some information:

Approaches toward the preparative-scale synthesis of target 3,4-dihydro-1(2H)-isoquinolinones [I; R = 7-Me, 5-Me, 5-O(CH2)3NHMe] are presented. I (R = 7-Me, 5-Me) were prepared via a Schmidt rearrangement on easily obtained indanone precursors, but in low overall yield. A better method to make this class of compounds is exemplified by the large-scale synthesis of I (R = 5-Me) via a Curtius rearrangement sequence. Thus, high-temperature thermal cyclization of an in situ formed styryl isocyanate in the presence of tributylamine gave the corresponding 1(2H)-isoquinolinone, which underwent catalytic hydrogenation to provide the desired I (R = 5-Me) in 65% overall yield. Similar reduction of a com. available 5-hydroxy-1(2H)-isoquinolinone precursor, followed by an O-alkylation/amination sequence, gave target I [R = 5-O(CH2)3NHMe] in good overall yield. The route proceeding via the Curtius rearrangement is recommended for large scale synthesis of other 3,4-dihydro-1(2H)-isoquinolinones. Only when deactivating substituents or sensitive functionality within the benzenoid ring render the high temperature ring closure of the intermediate isocyanate inefficient might a Schmidt rearrangement protocol be the method of choice. In the experiment, the researchers used 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one(cas: 129075-56-5Safety of 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one)

Marcou, Gilles; Rognan, Didier published an article on February 28 ,2007. The article was titled 《Optimizing Fragment and Scaffold Docking by Use of Molecular Interaction Fingerprints》, and you may find the article in Journal of Chemical Information and Modeling.Category: isoquinoline The information in the text is summarized as follows:

Protein-ligand interaction fingerprints have been used to postprocess docking poses of three ligand data sets: a set of 40 low-mol.-weight compounds from the Protein Data Bank, a collection of 40 scaffolds from pharmaceutically relevant protein ligands, and a database of 19 scaffolds extracted from true cdk2 inhibitors seeded in 2230 scaffold decoys. Four popular docking tools (FlexX, Glide, Gold, and Surflex) were used to generate poses for ligands of the three data sets. In all cases, scoring by the similarity of interaction fingerprints to a given reference was statistically superior to conventional scoring functions in posing low-mol.-weight fragments, predicting protein-bound scaffold coordinates according to the known binding mode of related ligands, and screening a scaffold library to enrich a hit list in true cdk2-targeted scaffolds.

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.

Mitra, Anindita; Biswas, Ria; Bagchi, Angshuman; Ghosh, Rita published their research in International Journal of Biological Macromolecules on December 1 ,2019. The article was titled 《Insight into the binding of a synthetic nitro-flavone derivative with human poly (ADP-ribose) polymerase 1》.Category: isoquinoline The article contains the following contents:

Flavones are important bioactive compounds, many of which are effective in cancer therapy for their ability to target enzymes related to DNA repair and cell proliferation. In this report, the interaction of a synthetic nitroflavone, 2,4-nitrophenylchromen-4-one (4NCO) with human poly (ADP-ribose) polymerase 1 (hPARP1) was investigated to explore its inhibitory action. Its interaction with hPARP1 was compared with that of other inhibitors through mol. docking studies. Further insight into the 4NCO-hPARP1 interaction was obtained from competitive docking and mol. dynamic simulation studies. In silico mutagenesis studies and per-residue interaction energy calculations were carried out. Quant. Structure Activity Relationship anal. was also performed to calculate its predictive percent inhibitory activity. Our results indicated that 4NCO exhibited competitive mode of binding to hPARP1. It formed a stable interaction with the protein thereby hindering any further mol. interaction to render it inactive with a predictive inhibition of 96%. It also had good ADMET properties and showed best Autodock binding free energy values compared to other known inhibitors. 4NCO showed good hPARP1 inhibitory properties with higher bioavailability and lower probability of getting effluxed. Development of inhibitors against hPARP1 is important for cell proliferative disorders, where 4NCO can be predicted as a potential new drug.

And the article was published in Journal of Chemical and Pharmaceutical Research in 2017. Recommanded Product: 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one The author mentioned the following in the article:

Poly (ADP-ribose) polymerase-1 (PARP1) is involved in DNA repair, its inhibition can potentiate cell killing by different agents. When used in conjunction, inhibitors of PARP1 can sensitize the action of chemotherapeutic agents thus making PARP1 an attractive target for therapeutic intervention in cancer. Docking of 9-Ph acridine (ACPH) with human PARP1 (hPARP1) revealed that ACPH could bind by interacting with the catalytically important amino acids at its NAD+ binding pocket. Its binding free energy was also determined to compare with that of other known inhibitors. Mol. dynamic simulation also established the binding of ACPH at the NAD+ binding pocket and also revealed its interaction with the catalytically important residues. These findings indicated that ACPH can be a potent hPARP1 inhibitor. In cultured A375 cells, post treatment with ACPH could sensitize cells to killing in both exponential and quiescent cells. NAD+ is the substrate for hPARP1 in DNA damaged cells; hence depletion of NAD+ indicates hPARP1 activity. The NAD+ content of treated cells were determined biochem. Post treatment with ACPH prevented NAD+ depletion in the DNA damaged cells confirming its hPARP1 inhibitory activity. Considering the significance of hPARP1 inhibitors not only in cancer therapeutics but in various pathol. conditions, the findings could be noteworthy for new drug development.

And the article was published in International Journal of Radiation Oncology, Biology, Physics in 1992. COA of Formula: C10H11NO The author mentioned the following in the article:

The ability of DNA repair inhibitors to potentiate alkylating agent cytotoxicity was explored with PD 128763, a dihydroisoquinolinone known to effectively inhibit poly(ADP-ribose) synthetase. The cytotoxic activity of streptozotocin in L1210 leukemia cells was maximally potentiated (7-fold decrease in IC50) under conditions of 24 h exposure to PD 128763 following treatment with the alkylating agent for 1 h. Similar treatment conditions resulted in a much greater effect (36-fold enhancement in activity) for the 2-nitroimidazole RSU 1069. In contrast, 3-aminobenzamide was only weakly effective at enhancing activity of either streptozotocin or RSU 1069 (2-3 fold potentiation). However, PD 128763 was ineffective at potentiating the cytotoxicity of the bifunctional alkylating agents carmustine (BCNU) and lomustine (CCNU). These results are consistent with a role for (poly-ADP) ribosylation in the repair of monofunctional alkylating agent damage. This study supports further exploration of the combination of PD 128763 and RSU 1069 as a potentially useful chemotherapeutic regimen. In the experiment, the researchers used 5-Methyl-3,4-dihydroisoquinolin-1(2H)-one(cas: 129075-56-5COA of Formula: C10H11NO)

Ruf, Armin; de Murcia, Josiane Menissier; de Murcia, Gilbert M.; Schulz, Georg E. published an article in Proceedings of the National Academy of Sciences of the United States of America. The title of the article was 《Structure of the catalytic fragment of poly(ADP-ribose) polymerase from chicken》.SDS of cas: 129075-56-5 The author mentioned the following in the article:

The crystal structures of the catalytic fragment of chicken poly(ADP-ribose) polymerase [NAD+ ADP-ribosyltransferase; NAD+:poly(adenosine-diphosphate-D-ribosyl)-acceptor ADP-D-ribosyltransferase, EC 2.4.2.30] with and without a nicotinamide-analog inhibitor have been elucidated. Because this enzyme is involved in the regulation of DNA repair, its inhibitors are of interest for cancer therapy. The inhibitor shows the nicotinamide site and also suggests the adenosine site. The enzyme is structurally related to bacterial ADP-ribosylating toxins but contains an addnl. α-helical domain that is suggested to relay the activation signal issued on binding to damaged DNA.
