The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Antioxidant-substituted tetrapyrazinoporphyrazine as a fluorescent sensor for basic anions.

Tetrapyrazinoporphyrazine substituted at its periphery with eight antioxidant 3,5-di-t-butyl-4-hydroxyphenyl groups behaves as a turn-on fluorescent sensor for fluoride anions. Conversely, the precursor antioxidant-substituted 1,2-phthalonitrile was found to act in turn-off mode suggesting that the origin of the phenomenon lies at the phenolate-substituted 1,4-pyrazinyl moiety.

In order to improve the immunotherapeutical potential of H-Cys-Leu-Gly-Gly-Leu-Leu-Thr-Met-Val-OH (CLG) peptide, an Epstein-Barr virus (EBV) subdominant epitope derived from the membrane protein LMP2, we have synthesized and tested CLG analogs containing cis- and/or trans-4-aminocyclohexanecarboxylic acid (ACCA) replacing Gly-Gly and/or Thr-Met dipeptide units. All pseudopeptides were tested for metabolic stability and for their capacity to bind HLA-A2 mols. and to sensitize target cells to lysis. All new compounds exhibited higher enzymic resistance compared to the original CLG and some trans-ACCA-derivatives were able to associate HLA-A2 and to efficiently stimulate CTL responses directed against the CLG natural epitope.

The gas chromatog.-mass spectrometry was used to isolate and identify metabolites of non-transgenic and Bacillus thuringiensis transgenic maize. The non-targeted metabolomics technique was used to anal. the metabolic pathway and mechanism of two kinds of maize. The methanol was used as extractant and the N,O-bis(trimethylsilyl) trifluoroacetamide was used as derivatization reagent. 38 kinds of metabolites were isolated and identified from non-transgenic maize, and 61 kinds of metabolites were isolated and identified in Bacillus thuringiensis transgenic maize. The specific metabolites between non-transgenic and Bacillus thuringiensis transgenic maize were analyzed. The metabolic pathway of specific metabolites was analyzed by KEGG annotation. The metabolic mechanism of non-transgenic maize and Bacillus thuringiensis transgenic maize was explored. The result indicated there were more metabolites involved in metabolic pathways in Bacillus thuringiensis transgenic maize than in non-transgenic maize, and tricarboxylic acid cycle and energy metabolism pathways of Bacillus thuringiensis transgenic maize are found to be higher than that of non-transgenic maize. The metabolic pathway of Bacillus thuringiensis transgenic maize conforms to the biol. activity law.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile(SMILESS: N#CC1=NC(Cl)=C(Cl)N=C1C#N,cas:56413-95-7) is researched.Application of 400801-74-3. The article 《Crystalline salts of the ring-reduced tin(IV) dichloride hexadecachlorophthalocyanine and octachloro- and octacyanotetrapyrazinoporphyrazine macrocycles with strong electron-withdrawing ability》 in relation to this compound, is published in Dyes and Pigments. Let’s take a look at the latest research on this compound (cas:56413-95-7).

Substituted tin(IV) dichloride phthalocyanine and tetrapyrazinoporphyrazines with acceptor chloro- or cyano-substituents: SnIVCl2(PcCl16), SnIVCl2(TPyzPzCl8) and SnIVCl2{TPyzPz(CN)8}, where PcCl16 = hexadecachlorophthalocyanine; TPyzPz(CN)8 = octacyanotetrapyrazinoporphyrazine, TPyzPzCl8 = octachlorotetrapyrazinoporphyrazine were synthesized. The reduction of these metallomacrocycles by fullerene {cryptand(Na+)}(C•-60) salt (1, 3 and 4) or potassium graphite (KC8) in the presence of cryptand (2) yields crystalline anionic salts: {cryptand(Na+)}2[SnIVCl2(PcCl4-16)]2-·C6H4Cl2 (1), {cryptand(K+)}2[{SnII(PcCl4-16)}0.926{SnIVCl2(PcCl4-16)}0.074]2-·2C6H4Cl2 (2), {cryptand(Na+)}[SnIVCl2{TPyzPz(CN)•3-8}]•-·C6H4Cl2 (3) and {cryptand(Na+)}2[SnIVCl2(TPyzPzCl4-8)]2-·2C6H4Cl2 (4). Reduction of SnIVCl2(macrocycle2-) with dianion macrocycles is accompanied by the formation of radical trianion or tetraanion macrocycles in 1-4. As stronger reductant, KC8 reduces the macrocycle and in addition nearly complete metal centered reduction from tin(IV) to tin(II) took place. Strong blue shift of the Q-band and new absorption bands are observed in the NIR range in the spectra of 1-4. Partial disruption of macrocycle aromaticity and alternation of the C – Nmeso bonds were found for the reduced macrocycles. Macrocycles are planar, and SnIV atoms are positioned exactly in the macrocycle plane. The only exception is strong distortion of the PcCl16 macrocycle in SnII(PcCl4-16) (2). Structures of 1-4 contain layers from the macrocycles having the side-by-side contacts in 1, 2, 4 and separated by cationic layers. Salt 3 presents the first structure of the TPyzPz(CN)8 macrocycle with strongest acceptor properties among known porphyrins and porphyrazines. It was shown that tetraanion macrocycles are diamagnetic in 1, 2 and 4. The [SnIVCl2{TPyzPz(CN)8•3-}]•- radical anions are paramagnetic in 3 with effective magnetic moment of 1.64μB, and salt 3 shows moderate antiferromagnetic coupling of spins with Weiss temperature of -14 K.

Electric Literature of C6Cl2N4. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Syntheses and Langmuir-Blodgett film formation of donor-acceptor molecules. Author is Zhu, Daoben; Yang, Chun; Liu, Yunqi; Xu, Yu.

Several novel organic mols. with donor-acceptor structure were designed and synthesized as non-linear optical (NLO) materials. Stable Langmuir films were formed at the air-water interface. Under appropriate exptl. conditions monolayers of these mols. were deposited in a Z-type mode. The Langmuir-Blodgett (LB) films were characterized by UV-visible spectroscopy, SEM and low-angle x-ray diffraction measurement. The NLO behavior of their monolayers was evaluated from second harmonic generation (SHG).

The article 《Cationic azaphthalocyanines bearing aliphatic tertiary amino substituents-Synthesis, singlet oxygen production and spectroscopic studies》 in relation to this compound, is published in Journal of Photochemistry and Photobiology, A: Chemistry. Let’s take a look at the latest research on this compound (cas:56413-95-7).

New cationic zinc azaphthalocyanines (AzaPc) were prepared using a statistical method of synthesis starting from 5,6-bis(2-diethylaminoethylsulfanyl)pyrazine-2,3-dicarbonitrile (A) and 5,6-bis(tert-butylsulfanyl)pyrazine-2,3-dicarbonitrile (B). All the six possible AzaPc derivatives were detected on TLC but only five of them were finally isolated using column chromatog. on silica (excluding AAAB type). The adjacent (AABB) and opposite (ABAB) isomers were well separated Singlet oxygen quantum yields (ΦΔ) were measured using the DPBF decomposition method. Values of ΦΔ in anhydrous DMF drastically decrease with the number of amino groups from 0.66 for BBBB type to 0.04 for AAAA type. The same dependence was observed in anhydrous DMF for the corresponding hydrochlorides. When DMF/water 95:5 added with HCl was used, the ΦΔ values for amino AzaPc increased to approx. 0.66. This suggests that solvation of the amino and Cl- ions plays an important role in the separation of the AzaPc mols. although no changes were found in UV-vis spectra. At least eight cationic charges are necessary for complete monomerization of AzaPc in water. Fewer charges lead to significant decrease of the absorption in the area of the Q-band and to pronounced dimeric character of the absorption spectrum.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.
