Formula: C6H6N2O. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Picolinamide, is researched, Molecular C6H6N2O, CAS is 1452-77-3, about Metal-free nitrogen -doped carbon nanosheets: a catalyst for the direct synthesis of imines under mild conditions. Author is Wang, Kaizhi; Jiang, Pengbo; Yang, Ming; Ma, Ping; Qin, Jiaheng; Huang, Xiaokang; Ma, Lei; Li, Rong.

Herein, a highly stable, porous, multifunctional and metal-free catalyst was developed, which exhibited significant catalytic performance in the oxidation of amines and transfer hydrogenation of nitriles under mild conditions; this could be attributed to the presence of numerous active sites and their outstanding BET surface area. The obtained results showed that most of the yields of imines exceeded 90%, and the cycling performance of the catalyst could be at least seven runs without any decay in the reaction activity, which could be comparable to those of metal catalysts. Subsequently, a kinetic study has demonstrated that the apparent activation energy for the direct synthesis of imines from amines is 67.39 kJ mol-1, which has been performed to testify that the catalytic performances are rational. Via catalyst characterizations and exptl. data, graphitic-N has been proven to be the active site of the catalyst. Hence, this study is beneficial to comprehend the mechanism of action of a metal-free N-doped carbon catalyst in the formation of imines.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1452-77-3, is researched, SMILESS is O=C(N)C1=NC=CC=C1, Molecular C6H6N2OJournal, Article, Molecules called Dihydrofolate Reductase Inhibitors: The Pharmacophore as a Guide for Co-Crystal Screening, Author is Baptista, Joao A.; Rosado, Mario T. S.; Castro, Ricardo A. E.; Evora, Antonio O. L.; Maria, Teresa M. R.; Ramos Silva, Manuela; Canotilho, Joao; Eusebio, M. Ermelinda S., the main research direction is crystal screening dihydrofolate reductase inhibitor pharmacophore trimethoprim pyrimethamine pyridinecarboxamide; 2,4-diaminopyrimidine; caffeine; co-crystal screening; dihydrofolate reductase inhibitors; pharmacophore; pyridinecarboxamides; pyrimethamine; theophylline; trimethoprim.HPLC of Formula: 1452-77-3.

In this work, co-crystal screening was carried out for two important dihydrofolate reductase (DHFR) inhibitors, trimethoprim (TMP) and pyrimethamine (PMA), and for 2,4-diaminopyrimidine (DAP), which is the pharmacophore of these active pharmaceutical ingredients (API). The isomeric pyridinecarboxamides and two xanthines, theophylline (THEO) and caffeine (CAF), were used as co-formers in the same exptl. conditions, in order to evaluate the potential for the pharmacophore to be used as a guide in the screening process. In silico co-crystal screening was carried out using BIOVIA COSMOquick and exptl. screening was performed by mechanochem. and supported by (solid + liquid) binary phase diagrams, IR spectroscopy (FTIR) and X-ray powder diffraction (XRPD). The in silico prediction of low propensities for DAP, TMP and PMA to co-crystallize with pyridinecarboxamides was confirmed: a successful outcome was only observed for DAP + nicotinamide. Successful synthesis of multicomponent solid forms was achieved for all three target mols. with theophylline, with DAP co-crystals revealing a greater variety of stoichiometries. The crystalline structures of a (1:2) TMP:THEO co-crystal and of a (1:2:1) DAP:THEO:ethyl acetate solvate were solved. This work demonstrated the possible use of the pharmacophore of DHFR inhibitors as a guide for co-crystal screening, recognizing some similar trends in the outcome of association in the solid state and in the mol. aggregation in the co-crystals, characterized by the same supramol. synthons.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, European Journal of Medicinal Chemistry called Structure-activity relationship study of THZ531 derivatives enables the discovery of BSJ-01-175 as a dual CDK12/13 covalent inhibitor with efficacy in Ewing sarcoma, Author is Jiang, Baishan; Jiang, Jie; Kaltheuner, Ines H.; Iniguez, Amanda Balboni; Anand, Kanchan; Ferguson, Fleur M.; Ficarro, Scott B.; Seong, Bo Kyung Alex; Greifenberg, Ann Katrin; Dust, Sofia; Kwiatkowski, Nicholas P.; Marto, Jarrod A.; Stegmaier, Kimberly; Zhang, Tinghu; Geyer, Matthias; Gray, Nathanael S., which mentions a compound: 882562-40-5, SMILESS is ClC1=NC(C2=CN(C3=C2C=CC=C3)S(=O)(=O)C2=CC=CC=C2)=C(Cl)C=N1, Molecular C18H11Cl2N3O2S, Related Products of 882562-40-5.

Development of inhibitors targeting CDK12/13 is of increasing interest as a potential therapy for cancers as these compounds inhibit transcription of DNA damage response (DDR) genes. We previously described THZ531, a covalent inhibitor with selectivity for CDK12/13. In order to elucidate structure-activity relationship (SAR), we have undertaken a medicinal chem. campaign and established a focused library of THZ531 analogs. Among these analogs, BSJ-01-175 demonstrates exquisite selectivity, potent inhibition of RNA polymerase II phosphorylation, and downregulation of CDK12-targeted genes in cancer cells. A 3.0 Å co-crystal structure with CDK12/CycK provides a structural rational for selective targeting of Cys1039 located in a C-terminal extension from the kinase domain. With moderate pharmacokinetic properties, BSJ-01-175 exhibits efficacy against an Ewing sarcoma tumor growth in a patient-derived xenograft (PDX) mouse model following 10 mg/kg once a day, i.p. administration. Taken together, BSJ-01-175 represents the first selective CDK12/13 covalent inhibitor with in vivo efficacy reported to date.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: cis-Dichlorobis(pyridine)platinum(II)( cas:15227-42-6 ) is researched.Category: tetrahydroisoquinoline.Teicher, Beverly A.; Rockwell, Sara; Lee, Jonathan B. published the article 《Radiosensitization of EMT6 cells by four platinum complexes》 about this compound( cas:15227-42-6 ) in International Journal of Radiation Oncology, Biology, Physics. Keywords: radiosensitization EMT cell platinum complex; oxygen radiosensitization platinum complex. Let’s learn more about this compound (cas:15227-42-6).

The radiosensitization of oxygenated and hypoxic exponentially growing EMT6 cells in vitro was measured. The dose modifying factors obtained with 200 and 400 μM trans-bis(2-nitroimidazole)dichloroplatinum II (NIPt) in hypoxic cells were 1.5 and 2.1, resp. For trans-bis(2-amino-5-nitrothiazole)dichloroplatinum II (Plant) under the same conditions, the dose modifying factor was 1.5 at 200 μM and 1.8 at 400 μM. Neither compound sensitized oxygenated cells when tested under similar protocols. Unlike the trans complexes, (1,2-diamino-4-nitrobenzene)dichloroplatinum II (Plato) was cytotoxic toward the hypoxic cells in the absence of x-rays. The time course of cytotoxicity for 100 μM Plato in exponentially growing cells showed rapid killing of hypoxic cells, and much less toxicity toward oxygenated cells. In radiosensitization studies, dose modifying factors of 1.6 and 2.0 were found with 200 and 400 μM Plato, resp., in hypoxic cells. The compound did not sensitize aerobic cells. The well known Pt complex cis-dipyridinedichloroplatinum II (PyPt) represents a cis-Pt heterocyclic aromatic complex that does not have a nitro-functionality. The dose modifying factor obtained with 400 μM PyPt in hypoxic cells was 1.7. On a molar basis, the nitro-functional Pt complexes appear to be more effective as hypoxic cell radiosensitizers than the corresponding free ligands.

F., which mentions a compound: 15227-42-6, SMILESS is [Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2, Molecular C10H10Cl2N2Pt, HPLC of Formula: 15227-42-6.

Kinetic data were obtained for the hydrolysis of [PtenCl2], cis- and trans-[Pt(NH3)2Cl2], cis-[Ptpy2Cl2], and [Pten(NO2)Cl] and for the replacement of Cl by NH3 in trans-[Pt(NH3)2Cl2]. The medium was H2O and mixtures of H2O with MeOH, EtOH, or Me2CO, the concentration of the organic component being 30 and 40 weight % in the hydrolysis and replacement reactions, resp. The lowering of the reaction rate in the presence of the organic component is explained by a structure-dependent contribution of the component to the solvation energy of an intermediate complex. The hydrolysis reaction is assumed to proceed in 2 steps: (1) formation of an intermediate complex by a slow coordination of the H2O mol. to the Pt2+ central ion without release of Cl- and (2) by a quick release of Cl-. The bond polarization occurs during the 1st step and the rate constant, k, should equal the ratio of the activity coefficients of the initial and activated complexes.
