Author is Antonello, Sabrina; Formaggio, Fernando; Moretto, Alessandro; Toniolo, Claudio; Maran, Flavio.

The electron transfer to peresters was studied by electrochem. means in N,N-dimethylformamide. The reduction was carried out by three independent methods: (i) heterogeneously, by using glassy carbon electrodes, (ii) homogeneously, by using electrogenerated radical anions as the donors, and (iii) intramolecularly, by using purposely synthesized donor-spacer-acceptor (D-Sp-A) systems (tert-Bu 1,3-dihydro-α,α-di-Methyl-1,3-dioxo-peroxy-2H-isoindole-2-acetate and tert-Bu cis-4-Phthalimidocyclohexanepercarboxylate). Convolution anal. of the heterogeneous data led to results in excellent agreement with the dissociative electron transfer theory. The homogeneous redox catalysis data also confirmed the reduction mechanism. The cyclic voltammetries of the D-Sp-A mols. could be simulated, leading to determination of the corresponding intramol. dissociative rate constants Anal. of the results showed that, regardless of the way by which the acceptor is reduced, the investigated dissociative electron transfers are strongly nonadiabatic and, particularly, that the exptl. rates are several orders of magnitude smaller than the adiabatic limit. A possible mechanism responsible for the observed behavior is discussed.

Kinetic study of the reaction of (+)-3-methyl-cyclohexanone with malononitrile. Author is Prout, Franklin S.; Beaucaire, Victor D.; Dyrkacz, Gary R.; Koppes, William M.; Kuznicki, Robert E.; Marlewski, Theordore A.; Pienkowski, James J.; Puda, Jacqueline M..

The condensation of malononitrile with (+)-3-methylcyclohexanone produced an 80-85% yield of (-)-3-methylcyclohexylidenemalononitrile. The reaction, followed polarimetrically in aqueous alc., is kinetically second order and efficiently catalyzed by weak bases (ω-amino acids, cyclic amino acids, NH4OAc) furnishing solutions having an apparent pH 7.5-8.0. With β-alanine as catalyst, the Ea was 7.6 kcal/mole compared to 11 kcal/mole uncatalyzed. Stronger bases (Barbital, NaOAc, LOAc, KF, piperidine) effect more rapid condensation but poorer kinetics because of telomerization of malononitrile at the higher pHs.

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. Compound: cis-4-Aminocyclohexane carboxylic acid, is researched, Molecular C7H13NO2, CAS is 3685-23-2, about Characterization of an inhibitory receptor in rat hippocampus. A microiontophoretic study using conformationally restricted amino acid analogs.Recommanded Product: 3685-23-2.

The inhibitory potencies of GABA [56-12-2], β-alanine [107-95-9], and glycine [56-40-6] in rat hippocampal pyramidal cells were determined and compared with those of substituted aminocyclopentane and aminocyclohexane carboxylic acids (ACPC and ACHC resp.). The order of effectiveness of the small aliphatic amino acids was GABA > β-alanine > glycine. GABA-induced inhibition was inhibited by iontophoresis of bicuculline or picrotoxin but not strychnine-HCl. The inhibitory abilities of the substituted ACPC and ACHC derivatives was a direct function of the separation of NH2 and CO2H groups in both series of cyclic amino acids. The most potent inhibition was observed when the spatial separation was similar to that of the extended GABA mol. (4.74 Å). Inhibition by (±)-cis-3-aminocyclopentanecarboxylic acid was blocked by simultaneous application of bicuculline or picrotoxin, but not by strychnine-HCl. The physiol. active conformation of GABA is probably the fully extended mol. and one dimension of the postsynaptic receptor site is probably within the range 4.2-4.8 Å.

Keywords: beta turn mimetic acetylamino cyclohexanecarboxamide preparation. Let’s learn more about this compound (cas:3685-23-2).

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.

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.

Thirteen new, stable, push-pull systems featuring dimethylamino and pyrazine-2,3-dicarbonitrile moieties as the donor and acceptor, resp., and systematically extended and varied π-linkers were prepared and studied. Evaluation of the measured UV/Vis spectra, electrochem. data (cyclic voltammetry, rotating disk voltammetry, and polarog.), x-ray data, and exptl. determined and calculated hyperpolarizability values enabled structure-property studies; these revealed some important structural features that affected the efficiency of intramol. charge-transfer and nonlinear optical properties in this class of heterocyclic push-pull chromophores. The charge-transfer transition was most significantly affected by structural features such as π-linker length, chromophore planarity, and the number of 1,4-phenylene/ethynylene subunits in the π-linker.

Author is Takeda, Takashi; Ikemoto, Tomohiro; Yamamoto, Shunsuke; Matsuda, Wakana; Seki, Shu; Mitsuishi, Masaya; Akutagawa, Tomoyuki.

A series of electron-accepting azaacene-type materials with different kinds and degrees of intermol. interactions were synthesized. Simple modification of the terminal substituents significantly modulated the photophys. and electrochem. properties. The degree of the weak intermol. interaction determined the emergence of a liquid crystalline (LC) phase for each compound Dipole-dipole interaction, π-π interaction and van der Waals interaction all contributed to stabilize the LC phase of I [R = C6H13, C12H25, C18H37] and II. The introduction of strong hydrogen bonding interaction enabled the formation of a highly ordered LC phase in III. Charge-transport properties of I, II and III were also investigated.
