We examine the relationship between covalent structure and conformational propensity among a series of beta-amino acid tetramers. These experiments focus on the hairpin folding motif. Among conventional peptides, the minimum increment of beta-sheet secondary structure is a ‘beta-hairpin,’ in which two strands are connected via a short loop. The present studies are aimed at optimizing hairpin stability among beta-peptides. Previous work from our laboratory has identified optimal substitution patterns for residues that form strands in an antiparallel beta-peptide sheet (Krauthauser et al. J. Am. Chem. Soc. 1997, 119, 11719), and we have shown that a dinipecotic acid segment can promote sheet-type interactions between attached strand residues (Chung et al. J. Am. Chem. Soc. 1998, 120, 10555). Here we compare all four possible configurations of the dinipecotic acid segment, (R,S), (S,R), (R,R) and (S,S), for the ability to induce sheet formation with a constant set of enantiomerically pure strand residues. We show that both heterochiral dinipecotic acid segments promote hairpin formation, although one is distinctly superior. Neither of the homochiral dinipecotic acid supports hairpin folding. When the strand residues are beta-alanine (achiral), the heterochiral dinipecotic acid segment is again superior to the homochiral segment, but we find a difference between hairpin conformations in solution and in the solid state.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Quality Control of: 1-Aminopiperidine, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 2213-43-6, Name is 1-Aminopiperidine, molecular formula is C5H12N2. In a Article, authors is Ghavtadze, Nugzar，once mentioned of 2213-43-6

(Chemical Equation Presented) Trifluoromethyl-substituted 1-amino-1-azapenta-1,4-dien-3-ones 4, which are accessible in good yield from pyruvates 1 in a three-step procedure, undergo a cascade reaction involving inter alia two electrocyclizations upon treatment with a large excess of trifluoromethanesulfonic acid to give novel dihydrospiroindenepyrazole 5a-o and dihydroindenodiazepine 6a-j. We interpret this sequence of reactions on the basis of quantum chemical calculations as a dicationic cyclization of a pentadien-1-one (“superelectrophilic solvation”), where one of the double bonds is part of an aromatic ring and a subsequent rearrangement to form an (monocationic) iminium ion, which either cyclizes to give five-membered spiro ring systems (compounds 5) or tricyclic dihydroindenodiazepine derivatives 6. Hueckel- and Moebius-type transition states of the electrocyclization reactions are discussed considering the results of NICS calculations. One 1-amino-1-penta-1,4-dien-3-one 4 and several dihydrospiroindenepyrazoles 5 and dihydroindenodiazepines 6 could be characterized by X-ray diffraction.

In a Article, authors is Lovely, Ann E.，once mentioned of 3433-37-2

(Chemical Equation Presented) Enantiomeric discrimination is observed in the 1H and 13C NMR spectra of piperidines and piperazines in the presence of (-)-(18-crown-6)-2,3,11,12-tetracarboxylic acid. The amines are protonated by the carboxylic acid groups of the crown ether to produce the corresponding ammonium and carboxylate ions. Association of the ammonium ion with the crown ether likely involves two hydrogen bonds with the crown ether oxygen atoms and an ion pair with the carboxylate anion. Methyl, hydroxymethyl, phenyl, carboxyl, pyridyl, and cyclohexyl substituent groups alpha to the nitrogen atom do not inhibit binding of the ammonium ion to the crown ether. The NMR spectra of piperidines with the stereogenic center alpha or beta to the nitrogen atom exhibit substantial enantiomeric discrimination. Dibasic substrates such as the piperizines are likely converted to their diprotonated form in the presence of the crown ether, and both nitrogen atoms appear to associate with the crown ether moiety.

Synthetic Route of 1121-89-7, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1121-89-7, name is Piperidine-2,6-dione. In an article，Which mentioned a new discovery about 1121-89-7

The pyrolysis of aliphatic alpha-amino acids, glutamine, glutamic and aspartic acids, and formation of heterocyclic and polycyclic aromatic hydrocarbons (N-PACs and PAHs) were studied. Each amino acid was first pyrolyzed at 300 C to obtain a low-temperature tar (LTT) and a low-temperature char (LTC). The LTC was then pyrolyzed at 625 C to obtain the corresponding high-temperature tar (HTT) and high-temperature char (HTC). The tars were separately subjected, in some cases, to temperatures in the range 700-870 C to study secondary reactions. Oligomers of aspartic acid and glutamic acid were also pyrolyzed. The tars were analyzed by gas chromatography/mass spectrometry. Glutamic acid and glutamine underwent significant decomposition to volatile products at 300 C but aspartic acid required higher temperature. The heterocyclic compounds were primarily single-ring compounds comprised of five- or six-member heterocycles in the absence of secondary reactions, and up to four rings after the secondary pyrolysis. The PACs included nitriles from glutamine and glutamic acid and PAHs from aspartic acid. For aspartic acid, the results from oligomers were similar to those from the monomer, whereas the results from the glutamic acid oligomer were slightly different from glutamic acid. All three acids appeared to break down to smaller “building blocks” and then pyrosynthesize the N-PACs and PAHs.

Alzheimer?s disease (AD) is the leading cause of dementia in old people worldwide and one of the leading causes of death in developed countries. The current poor understanding of AD mechanisms makes it difficult to develop novel drugs that could be used to treat effectively this disease. Different enzymes are known to be crucial in the biochemical pathways involved in the development of AD and therefore can be considered as potential targets to design efficient drugs. Among them, three enzymes stand out: acetylcholinesterase (AChE), beta-amyloid cleaving enzyme 1 (BACE1), and glycogen synthase kinase-3 (GSK-3). Chemoinformatics and molecular modeling methodologies have been used for decades for the selection and optimization of new compounds with therapeutic properties in different areas. The initial works in computational drug discovery (CDD) were only considered as promising theoretical studies. However, currently, these in silico methodologies are part of the normal drug discovery process, and they are usually implemented in the search of novel drugs or for the optimization of therapeutic activity (or pharmacokinetic properties) of chemical series. In particular, the search for drugs in the field of neurodegenerative disorders is very active, though unfortunately no cure exists nowadays for AD. In this review, we will present the advances on the use of computational techniques in the search for novel small molecules as effective therapeutic agents against AD. We will describe recent computational studies to find or design new anti-AD compounds applying different computational approaches, mainly quantitative structure-activity relationship (QSAR), molecular docking, pharmacophore development, and molecular dynamics simulations. Taking into account that there is a huge amount of literature on the field, we have chosen to focus on studies published in the last few years related to the main AD targets (AChE, BACE1, and GSK-3). We will conclude by providing a perspective on the future of this field.
