Cis-4-(Acetylamino)-N-(methyl)cyclohexanecarboxamide has been selected as all carbon ring analog of previously described 5-(amino)piperidinone-2-carboxylate systems. The potential β-turn-inducing properties of this model compound are evaluated by means of NMR anal. and mol. modeling. It was found that suitable as β-turn-inducing scaffold. Apparently, the planar lactam function in the native (amino)(oxo)piperidinecarboxylate systems is important to impose a correct conformation for β-turn induction.

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, Research Support, U.S. Gov’t, Non-P.H.S., Brain Research called Effects of some conformationally restricted GABA analogs on GABA membrane binding and nerve ending transport, Author is Hitzemann, Robert J.; Loh, Horace H., which mentions a compound: 3685-23-2, SMILESS is N[C@H]1CC[C@H](CC1)C(O)=O, Molecular C7H13NO2, Electric Literature of C7H13NO2.

By using a series of aminocyclopentane- and aminocyclohexanecarboxylic acids, as well as some naturally occurring amino acids, it was possible to determine some aspects of the spatial topog. of the GABA [56-12-2] membrane binding and transport sites in the rat brain. The Na-independent GABA binding site had a different spatial topog. than the Na-dependent binding site in that (±)-trans-3-aminocyclopentanecarboxylic acid (I) [19297-28-0] was 7-fold more potent than (±)-cis-3-aminocyclopentanecarboxylic acid (II) [49805-32-5] in inhibiting Na-independent binding, but only 1.6 times more potent in inhibiting Na-dependent binding. The nerve ending GABA transport site was similar to the Na-dependent GABA binding site in that it accommodated both I and II. However, the transport site differed from the binding site in that II was a potent inhibitor of transport but a weak inhibitor of binding. In addition to the differences in spatial characteristics, differences in the subcellular distribution of Na-independent and Na-dependent binding sites were observed The former were found primarily in the nerve ending-mitochondrial fraction, whereas the latter were primarily found in the microsomal fraction.

Safety of 5,6-Dichloropyrazine-2,3-dicarbonitrile. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile, is researched, Molecular C6Cl2N4, CAS is 56413-95-7, about Crystalline salts of the ring-reduced tin(IV) dichloride hexadecachlorophthalocyanine and octachloro- and octacyanotetrapyrazinoporphyrazine macrocycles with strong electron-withdrawing ability. Author is Faraonov, Maxim A.; Romanenko, Nikita R.; Kuzmin, Alexey V.; Konarev, Dmitri V.; Khasanov, Salavat S.; Lyubovskaya, Rimma N..

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.

Author is Tuhl, Ahmad; Makhseed, Saad; Zimcik, Petr; Al-Awadi, Nouria; Novakova, Veronika; Samuel, Jacob.

Two series of peripherally substituted azaphthalocyanines (AzaPcs) containing different transition metals (Al(III), Zn(II), Ga(III), In(III) and Fe(II)) were synthesized and studied for their photophys. properties. As confirmed by UV-visible and 1H NMR analyses, the non-aggregation behavior was effectively induced by the applied bulky peripheral substituents which had no effect on the photophys. properties. Tuning the Q-band position was clearly achievable by using different central heavy metals which have considerable effects on the fluorescence quantum yield and singlet oxygen generation efficiency. This comparative study showed an interesting linear relation between the former and at. number of the central metal. The indium containing complexes exhibited the best result due to the heavy metal effect and therefore could be promoted as a potential photosensitizer in photodynamic therapy (PDT) application.

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).

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Gampe, Dominique Mario; Kaufmann, Martin; Jakobi, Doerthe; Sachse, Torsten; Presselt, Martin; Beckert, Rainer; Goerls, Helmar researched the compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile( cas:56413-95-7 ).Category: chiral-oxygen-ligands.They published the article 《Stable and Easily Accessible Functional Dyes: Dihydrotetraazaanthracenes as Versatile Precursors for Higher Acenes》 about this compound( cas:56413-95-7 ) in Chemistry – A European Journal. Keywords: dihydrotetraazaanthracene dye; chromophores; cyclization; density functional calculations; nitrogen heterocycles; sensitizers. We’ll tell you more about this compound (cas:56413-95-7).

A series of new dihydrotetraazaanthracenes and one new dihydrotetraazatetracene as substances for applications in organoelectronic devices and as suitable building blocks for higher azaacenes was synthesized. The condensation of aromatic diamines with dichlorodicyanopyrazine led to these tricyclic/tetracyclic compounds Syntheses of N-substituted phenylenediamines were developed to enable the introduction of multiple functional groups such as ester, amino, or nitro groups on the chromophoric system. Relationships between the structure and the spectroscopic properties could be derived from UV/Vis absorption and fluorescence spectroscopy, and by DFT and TD-DFT calculations of mol. and aggregate structures. The absorption spectra are dominated by π-π* transitions of the single mols., whereas aggregation needs to be taken into account to obtain reasonable agreement between theory and experiment in certain cases. Single-crystal x-ray analyses were carried out to examine the morphol. and solid packing effects. Finally, a dihydrotetraazaanthracene was used as a building-block to create a mesoionic octaazapentacene.
