Morpholine-based immonium and halogenoamidinium salts as coupling reagents in peptide synthesis

Here we describe a new family of N-form immonium-type coupling reagents that differ in their carbocation skeleton structure. The N-methylpiperazine derivative failed to form immonium salts, while the thiomorpholine derivative did not give better results than the coupling reagents currently used. The presence of the morpholine had a marked influence on the solubility and stability as well as the reactivity of the reagent. Finally, the fluoroamidinium salt performed extremely well in the presence of only 1 equiv of base, thereby confirming the effect of the proton acceptor in the reaction.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Welcome to check out more blogs about 104-21-2, in my other articles. SDS of cas: 104-21-2.

Design, synthesis and primary activity of thiomorpholine derivatives as DPP-IV inhibitors

Thirteen thiomorpholine-bearing compounds were designed and synthesized as dipeptidyl peptidase IV (DPP-IV) inhibitors, with natural and non-natural L-amino acids as the starting materials. Their structures were characterized by H-1 NMR, C-13 NMR and HR-MS. The target compounds were screened for the DPP-IV inhibition, and the preliminary SAR result was obtained. Particularly, compounds 4c, 4d and 4f with good DPP-IV inhibition in vitro were further evaluated through a mouse oral glucose tolerance test (OGTT). The preliminary result showed the potential value for further studies on those thiomorpholine-bearing compounds as DPP-IV inhibitors. (C) 2011 Hai Hong Huang.

Chromatographic determination of morpholine and products of its microbiological degradation

A combination of thin-layer chromatography (TLC) with high-performance liquid chromatography (HPLC) was shown to be efficient in determining the intermediate products of the utilization of thiomorpholine with ligninolytic basidiomycete fungus Bjerkandera adusta VKM F-3477. The chromatographic mobility of the products of microbiological degradation of thiomorpholine was studied on Sorbfil PTSKh-P-V plates in the systems of chloroform-methanol-25% aqueous ammonia (80: 20: 2) for determining cyclic amines and isopropanol-25% aqueous ammonia (70: 30) for determining thio acids. The optimum conditions were selected for the separation of thiomorpholine and the formed metabolites by ion-exchange chromatography and reversed-phase chromatography.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Welcome to check out more blogs about 529-35-1, in my other articles. Synthetic Route of 529-35-1.

Synthesis and biological evaluation of heteroalicyclic cyanoguanidines at histamine receptors

Recent studies on histamine receptor (HR) subtypes identified imidazolyl butyl cyanoguanidines, like UR-PI376, as highly potent agonists at the human histamine H-4 receptor (hH(4)R). While imidazole-containing compounds display drawbacks in pharmacokinetics, we studied the possibility of replacing the heteroaromatic cycle by nonaromatic six-membered heterocycles (piperidine, morpholine, thiomorpholine, and N-methylpiperazine) as potential bioisosteres. Beyond that, this approach should give more information about the indispensability of the aromatic ring as a basic head group. Besides these changes, a variation of the spacer length (C-3-C-5) connecting the heterocycle and the cyanoguanidine moiety has been made to possibly trigger the selectivity towards the respective HRs. Investigations in radioligand-binding assays exhibited only very weak activity at the hH(1)R and hH(3)R, while nearly all compounds were inactive at the hH(2)R and hH(4)R. In the case of piperidine-containing compounds, moderate affinities at the hH(3)R over the single-digit micromolar range were detected.

Toward Rational Design of Amine Solutions for PCC Applications: The Kinetics of the Reaction of CO2(aq) with Cyclic and Secondary Amines in Aqueous Solution

The kinetics of the fast reversible carbamate formation reaction of CO2(aq) with a series of substituted cyclic secondary amines as well as the noncyclic secondary amine diethanolamine (DEA) has been investigated using the stopped-flow spectrophotometric technique at 25.0 degrees C. The kinetics of the slow parallel reversible reaction between HCO3- and amine has also been determined for a number of the amines by H-1 NMR spectroscopy at 25.0 degrees C. The rate of the reversible reactions and the equilibrium constants for the formation of carbamic acid/carbamate from the reactions of CO2 and HCO3- with the amines are reported. In terms of the forward reaction of CO2(aq) with amine, the order with increasing rate constants is as follows: diethanolamine D EA) < morpholine (MORP) similar to thiomorpholine (TMORP) < N-methylpiperazine (N-MPIPZ) < 4-piperidinemethanol (4-PIPDM) similar to piperidine (PIPD) < pyrrolidine (PYR). Both 2-piperidinemethanol (2-PIPDM) and 2-piperidineethanol (2-PIPDE) do not form carbamates. For the carbamate forming amines a Bronsted correlation relating the protonation constant of the amine to the carbamic acid formation rate and equilibrium constants at 25.0 degrees C has been established. The overall suitability of an amine for PCC in terms of kinetics and energy is discussed.

The effect of heterocyclic S,S ‘-ligands on the electrochemical properties of some cobalt(III) complexes in acid

Eight mixed-ligand cobalt(III) complexes with the macrocyclic amine 1,4,8,11 -tetraazacyclotetradecane (cyclam) and a heterocyclic dithiocarbamate (Rdtc(-)) i.e., morpholine- (Morphdtc), thiomorpholine- (Timdtc), piperazine- (Pzdtc), N-methylpiperazine- (Mepzdtc), piperidine- (Pipdtc), 2-, 3- or 4-methylpiperidine- (2-, 3- and 4-Mepipdtc) carbodithionato-S,S ions, of the general formula [Co(cyclam)Rdtc](ClO4)(2), were investigated in deoxygenated 0.1 M HClO4 solutions. Cyclic voltammetry data at a glassy carbon (GC) electrode demonstrate a redox reaction of cobalt(III) from the complexes at potentials strongly influenced by the presence of different heterocyclic Rdtc(-) ligands. In this respect, the complexes were separated into two groups: the first, with a heteroatom O, S or N in the heterocyclic ring, and the second, with a methyl group on the piperidine ring of the Rdtc(-) ligand. Anodic polarization of an Fe electrode in the presence of the complexes shows their influence not only on the dissolution of iron but also on the hydrogen evolution reactions and on this basis complexes the complexes could be divided into the same two groups. It was found that the weaker the inhibiting effect of the free heterocyclic amines is, the significantly higher is the efficiency of the corresponding complexes.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 5428-54-6, you can contact me at any time and look forward to more communication.

Cobalt(III) complexes with a tetraaza macrocyclic ligand and some heterocyclic dithiocarbamates

Four new cobalt(III) complexes of the general formula [Co(Rdtc)cyclam](ClO4)(2), where cyclam and Rdtc(-) refer to 1,4,8,11-tetraazacyclotetradecane and 2-, 3-, 4-methylpiperidine (2-, 3-, 4-wMeepipdtc(-)) or 4-thiomorpholine (Timdtc(-)) dithiocarbamates, respectively, have been prepared. Elemental and thermal analyses, VIS, IR and H-1 and C-13 NMR spectroscopy have been used to characterized them. In the complexes, cobalt is hexa-coordinated in an octahedral geometry of a folded macrocyclic ligand and dithiocarbamates are bound as bidentates. As regards to the influence of the position of the methyl group on the piperidine ring, the nu(C – N) and nu(C – S) values increase in the order 2-Mepipdtc(-) < 3-Mepipdtc(-) < 4-Mepipdtc(-). Furthermore, the position of the methyl substituent also influences the thermal stability of the complexes and the order of stability decreases in the opposite order. Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 5428-54-6, you can contact me at any time and look forward to more communication.
