Dipole oscillator strength distributions, sum rules, mean excitation energies, and isotropic van der Waals coefficients for benzene, pyridazine, pyrimidine, pyrazine, s-triazine, toluene, hexafluorobenzene, and nitrobenzene

Experimental, theoretical, and additive-model photoabsorption cross sections combined with constraints provided by the Kuhn-Reiche-Thomas sum rule and the high-energy behavior of the dipole oscillator strength density are used to construct dipole oscillator strength distributions for benzene, pyridazine (1,2-diazine), pyrimidine (1,3-diazine), pyrazine (1,4-diazine), s-triazine (1,3,5-triazine), toluene (methylbenzene), hexafluorobenzene, and nitrobenzene. The distributions are used to predict dipole sum rules S(k) for -6 <= k <= 2, mean excitation energies I(k) for -2 <= k <= 2, and isotropic van der Waals C-6 coefficients. A popular combination rule for estimating C-6 coefficients for unlike interactions from the C-6 coefficients of the like interactions is found to be accurate to better than 1% for 606 of 628 cases (96.4%) in the test set. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 103-85-5 help many people in the next few years.

Crystal design by CH center dot center dot center dot N and N center dot center dot center dot N interactions: high-pressure structures of high-nitrogen-content azido-triazolopyridazines compounds

High-nitrogen-content compounds 6-azido-1,2,4-triazolo[4,3-b]pyridazine (C5H3N7) and its 3-methyl derivative (C6H5N7) have been in situ crystallized in a diamond-anvil cell and their structures determined by single-crystal X-ray diffraction. Under ambient and high-pressure conditions the crystallizations yield the same phases: the C5H3N7 anhydrate and C6H5N7 hydrated clathrate. In both the structures there are clearly distinguished regions of short CH center dot center dot center dot N and N center dot center dot center dot N intermolecular contacts, the latter involving exclusively the azide groups. High pressure initially increases the contents of water in the channel pores of the clathrate.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 103-85-5, you can contact me at any time and look forward to more communication. Recommanded Product: 1-Phenylthiourea.

The anti-invasive role of novel synthesized pyridazine hydrazide appended phenoxy acetic acid against neoplastic development targeting matrix metallo proteases

Neoplastic metastasis is a major process where tumor cells migrate from the primary tumor and colonize at other parts of our body to form secondary tumor. Cancer incidences are rising and novel anti-neoplastic compounds with new mechanism of actions are essential for preventing cancer related deaths. In the current examination, a novel series of pyridazine analogues 6a-l was synthesized and evaluated against metastatic neoplastic cells. Experimental data postulated compound 6j has potential cytotoxic efficacy with prolonged activity against various cancer cells, including A549, HepG2, A498, CaSki and SiHa cells. Moreover, compound 6j arrests the A549 migration and invasions markedly by counteracting matrix metalloproteinase (MMP)-2 and MMP-9 expressions. Also, compound 6j proved its potentiality against Dalton’s solid lymphoma progression in-vivo by abridging MVD and MMP expressions. Compound 6j interacts with MMP-2 and MMP-9 by H-bond in-silico, thereby down regulates the MMPs action in tumourigenesis. Altogether, we concluded that compound 6j down regulates MMP-2 and MMP-9 and thereby impairs metastatic cancer cell migration and invasions which can be translated into a potent anti-neoplastic agent.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 103-85-5, in my other articles. SDS of cas: 103-85-5.

Constructing a novel nonlinear optical materials: substituents and heteroatoms in pi-pi systems effect on the first hyperpolarizability

By doping pi-pi systems with Li atom, a series of Li@sandwich configuration and Li@T-shaped configuration compounds have been theoretically designed and investigated using density functional theory. It is revealed that energy gaps (E (gap)) between highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) of all compounds are in a range of 0.4-0.9 ev. When Li atom is introduced into different sandwich configuration pi-pi systems (C-60-toluene, C-60-fluorobenzene, C-60-phenol, C-60-benzonitrile), Li@C-60-benzonitrile exhibits considerable first hyperpolarizability as large as 19,759 au, which is larger by about 18,372-18,664 au than those of other compounds. When Li atom is introduced into different T-shaped configuration pi-pi systems (C-60-pyridine, C-60-pyrazine, C-60-1, 3, 5-triazine, C-60-pyridazine), Li@C-60-pyridazine is found to present largest first hyperpolarizability up to 67,945 au in all compounds. All compounds are transparency in the deep ultraviolet spectrum range. We hope that this study could provide a new idea for designing nonlinear optical materials using pi-pi systems as building blocks.

Imidazo[1,2-b]pyridazines targeting Toxoplasma gondii calcium-dependent protein kinase 1 decrease the parasite burden in mice with acute toxoplasmosis

The current therapeutic arsenal for toxoplasmosis is restricted to drugs non-specific to the parasite which cause important side effects. Development of more efficient and specific anti-Toxoplasma compounds is urgently needed. Imidazo[1,2-b]pyridazines designed to inhibit the calcium-dependent protein kinase 1 of Toxoplasma gondii (TgCDPK1) and effective against tachyzoite growth in vitro at submicromolar ranges were modified into hydrochloride salts to be administered in vivo in a mouse model of acute toxoplasmosis. All protonated imidazo[1,2-b]pyridazine salts (SP230, SP231 and SP232) maintained their activity on TgCDPK1 and T. gondii tachyzoites. Rat and mouse liver microsomes were used to predict half-life and intrinsic clearance, and the pharmacokinetic profile of the most rapidly degraded imidazo [1,2b]pyridazine salt (SP230) was determined in serum, brain and lungs of mice after a single administration of 50 mg/kg. Compounds were then tested in vivo in a murine model of acute toxoplasmosis. Mice infected with tachyzoites of the ME49 strain of T. gondii were treated for 4, 7 or 8 days with 25 or 50 mg/kg/day of SP230, SP231 or SP232. The parasite burdens were strongly diminished (>90% reduction under some conditions) in the spleen and the lungs of mice treated with imidazo[1,2-b]pyridazine salts compared with untreated mice, without the need for pre-treatment. Moreover, no increases in the levels of hepatic and renal toxicity markers were observed, demonstrating no significant signs of short-term toxicity. To conclude, imidazo[1,2-b]pyridazine salts have strong efficacy in vivo on acute toxoplasmosis and should be further tested in a model of mouse congenital toxoplasmosis.

Synthesis and spectral characterization of some new azo benzothiazole derivative and relative compounds

A series of azo benzothiazole derivatives (2a-m) were prepared by coupling of the appropriate arylamine diazonium salts with 2-(benzo[d]thiazole-2-yl)-3-oxo-pentadinitriles (1). Also, the cyclization of azo derivatives (2d, 2h) with malononitrile in refluxing DMF afforded pyridazine carbonitrile derivatives (3a,b). Moreover, the azo derivatives (2a-m) underwent cyclization on refluxing in DMF to afford pyridazine derivatives (6a-m). All the newly synthesized compounds were characterized by both analytical and spectral analyses. Dyeing performance of the synthesized dyes on polyester fibers has been assessed. Most of the dyes showed good affinity to polyester fibers. No details regarding the synthesis and dyeing performance of such dyes are reported before in the literature.

Five Solid Forms of a Potent Imidazopyridazine Antimalarial Drug Lead: A Preformulation Study

A novel antimalarial drug lead, 6-(3-(methylsulfonyl)phenyl)-3-(4-(methylsulfonyl)phenyl)-imidazo[1,2-b]pyridazine (MMV652103), with good in vitro and in vivo antiplasmodial effects but poor aqueous solubility was investigated for preformulation beneficiation by supramolecular methods. Three polymorphs (Forms 1-3), an amorphous phase (Form 4), and a monohydrate (Form 5) were discovered and characterized by thermal analytical methods including hot stage microscopy, differential scanning calorimetry, and thermogravimetric analysis, complemented by variable-temperature powder X-ray diffraction. Single crystals of polymorphic Form 1, Form 2, and a monohydrate of the drug lead were isolated, and their structures were elucidated by X-ray diffraction, which enabled the respective molecular conformations, inter- and intramolecular interactions, and packing arrangements to be determined. A schematic energy-temperature diagram incorporating the polymorphic forms and the amorphous form of the drug lead was constructed using data gleaned from thermal analysis, kinetic solubility experiments, and observations of solvent-mediated transitions. The amorphous form of the drug lead displayed a significant increase in dissolution rate, yielding a maximum concentration of 3-4 times those of the crystalline forms after 1 h.

A study on synthesis and antimicrobial activity of 4-acyl-pyrazoles

4-Acyl-pyrazole-3-carboxylic acids (1) were synthesized via the reaction of 4-acyl-2,3-furandiones (F) with hydrazone (1-benzylidene-2-(2,5-dimethyl-phenyl)-hydrazine) by heating under solid phase and their acid chlorides (2) were obtained. Then these derivatives were easily converted into the corresponding derivatives such as ester, amide, ureide, pyrazolo-pyridazine, etc. Totally 62 new compounds were synthesized. The structures of these new synthesized compounds were determined by spectroscopic methods and the in vitro antibacterial activity of newly synthesized compounds were carried out against some gram-positive and gram-negative bacteria by well diffusion method (zone inhibition). Our results have showed that these new synthesized compounds have much potent of antibacterial activity owing to containing of pyrazole and/or pyridazine, chromone, oxazine, furane, and pyrrole rings. Some of the new pyrazole derivatives exhibited higher activities than reference drugs against the representative bacteria. (C) 2016 King Saud University. Production and hosting by Elsevier B.V.

Hydrolysis of the Amide Bond in L-Methionine- and L-Histidine-Containing Dipeptides in the Presence of Dinuclear Palladium(II) Complexes with Benzodiazines Bridging Ligands

H-1 NMR spectroscopy was applied to study the catalytic activity of dinuclear Pd(II)-aqua complexes with different benzodiazine bridging ligands, [{Pd(en)(H2O)}(2)(mu-qx)](4+)(Pd1), [{Pd(en)(H2O)}(2)(mu-qz)](4+)(Pd2) and [{Pd(en)(H2O)}(2)(mu-phtz)](4+)(Pd3) (qx, qz and phtz denote quinoxaline, quinazoline and phthalazine, respectively), in the hydrolytic cleavage of the amide bond inN-acetylated L-methionylglycine (Ac-L-Met-Gly) and L-histidylglycine (Ac-L-His-Gly) dipeptides. All reactions were investigated with an equimolar amount of the reactants at pH = 2.0-2.5 in D2O and at 37 degrees C. The obtained data for the catalytic activity ofPd1-Pd3complexes are compared with those previously reported for [{Pt(en)(H2O)}(2)(mu-L)](4+)(L denotes benzodiazine: qx, qz and phtz), [{Pd(en)(H2O)}(2)(mu-L)](4+)and [{Pt(en)(H2O)}(2)(mu-L)](4+)(L denotes diazine: pyrazine and pyridazine) complexes. It was found that catalytic activity of these complexes in peptide cleavage is strongly related to the position of the nitrogen atoms in the benzodiazine or diazine bridging ligand. The investigated dinuclear Pd(II) and Pt(II) complexes show catalytic activity in the selective hydrolysis of the Met-Gly amide bond of Ac-L-Met-Gly dipeptide. Moreover, all the above mentioned Pd(II) complexes were also able to catalyze the regioselective hydrolysis of the His-Gly amide bond of Ac-L-His-Gly dipeptide. However, in the reaction with Ac-L-His-Gly, only Pt(II) aqua complexes containing bridging ligands with two nitrogen atoms in thepara-position (quinoxaline and pyrazine) were able to cleave this dipeptide.
