The development of reaction kinetics for CO2 absorption into novel solvent Frustrated Lewis (FLPs)

Frustrated Lewis Pairs (FLPs) comprising sterically hindered Lewis acids and bases were developed and kinetic parameters for the homogenous reaction between CO2 and FLP dissolved in bromobenzene were obtained by using the stopped-flow method for the first time in the scope of this work. As a sterically hindered Lewis acid chlorobis(pentafluorophenyl)borane, B(C6F5)(2)Cl and as a sterically hindered Lewis base tri-tert-butylphosphine, tBu(3)P were analyzed. Experiments were performed by varying FLP concentration in bromobenzene medium over the range of 0.02-0.035 M and for a temperature range of 298-313 K. Modified termolecular reaction mechanism was used to analyse the experimental kinetic data. Then, the relatively low reaction rate of FLP: bromobenzene system was enhanced significantly by blending constant amounts of promoters, such as amino ethyl piperazine (AEPZ), carbonic anhydrase (CA) and 1-ethyl-3-methyl imidazolium bis (trifluoromethyl sulfonyl) imide ([emim][Tf2N]). The intrinsic reaction rates of promoted solvents were measured in a stopped-flow technique over a temperature range of 293-323 K. The empirical power law reaction orders with respect to FLP concentration were found to be between 1.0 and 2.0 at various temperatures. Additionally, at these operating conditions, the promoting effects of AEPZ, CA, and [emim][Tf2N] results in a higher reaction rate and lower activation energy values.

Supramolecular adducts of mesocyclic diamines with various carboxylic acids: Charge-assisted hydrogen-bonding in molecular recognition

Aggregation of saturated mesocyclic diamine 1,4-diazacycloheptane (dach) or piperazine (pipz) and diversiform carboxylic acids with mono- or di-carboxyls yields a series of novel binary supramolecular adducts via two-point molecular recognition. All the supramolecular assemblies were obtained by solvent evaporation method from different media. X-ray single-crystal diffraction analyses reveal that these supramolecular moieties present 1D chain motif, 2D flat, corrugated sheet structures and 3D CdSO4, pillar-layered networks through carboxylate-amide N-H center dot center dot center dot O, as well as its proton transfer form N+-H center dot center dot center dot O-, carboxyl head to tail O-H center dot center dot center dot O, and extended hydrogenbonding interactions. Their compositions and structures were also confirmed by Fourier transform infrared (FT-IR) spectroscopy. Thermal stability of these binary crystalline adducts has been investigated by thermogravimetric analysis (TGA), suggesting similar thermal stabilities. (C) 2020 The Author(s).

Ruthenium Catalyzed Regioselective beta-C(sp(3))-H Functionalization of N-Alkyl-N ‘-p-nitrophenyl Substituted Piperazines using Aldehydes as Alkylating Agents

Herein, we disclose a ruthenium-catalyzed regioselective beta-C(sp(3))-H bond functionalization on the piperazine core using aldehydes as alkylating agents. The present transformation appears to go through the dehydrogenation of the piperazine to propagate to enamine in situ, followed by nucleophilic addition to the aldehyde and hydrogenation to result in the regioselective beta-C(sp(3))-H alkylation. A variety of aromatic, heteroaromatic, aliphatic aldehydes were employed for the C-3 alkylation of N-alkyl-N ‘-p-nitrophenyl substituted piperazines.

Piperazine-tuned benzimidazole-based multifunctional fluorescent sensor for the detection of mercury (II) ion and pH

An organic chemical sensor (P) based on benzimidazole for detecting Hg2+ and pH in semi-aqueous media was described. P has a very high sensitivity and selectivity for Hg2+ in semi-aqueous media, and P monitoring Hg2+ with excellent anti-interference performance. Interestingly, H+ can remove Hg(2+ )from the [P-Hg2+] complex and restore the spectral signal of P. The sigmoidal fitting of pH-dependent fluorescence intensity provided an apparent pK(a) value of 6.51. This research may enrich the field of multi-functional chemosensors in natural products.

Activation of mu-opioid receptors by MT-45 (1-cyclohexyl-4-(1,2-diphenylethyl)piperazine) and its fluorinated derivatives

Background and Purpose A fluorinated derivative (2F-MT-45) of the synthetic mu-opioid receptor agonist MT-45 (1-cyclohexyl-4-(1,2-diphenylethyl)piperazine) was recently identified in a seized illicit tablet. While MT-45 is a Class A drug, banned in a number of countries, nothing is known about the pharmacology of 2F-MT-45. This study compares the pharmacology of MT-45, its fluorinated derivatives and two of its metabolites. Experimental Approach We used a beta-arrestin2 recruitment assay in CHO cells stably expressing mu receptors to quantify the apparent potencies and efficacies of known (MT-45, morphine, fentanyl and DAMGO) and potential agonists. In addition, the GloSensor protein was transiently expressed to quantify changes in cAMP levels. We measured Ca2+ to investigate whether MT-45 and its metabolites have effects on GluN1/N2A NMDA receptors stably expressed in Ltk- cells. Key Results The fluorinated MT-45 derivatives have higher apparent potencies (2F-MT-45: 42 nM) than MT-45 (1.3 mu M) for inhibition of cAMP accumulation and beta-arrestin2 recruitment (2F-MT-45: 196 nM; MT-45: 23.1 mu M). While MT-45 and 2F-MT-45 are poor recruiters of beta-arrestin2, they have similar efficacies for reducing cAMP levels as DAMGO. Two MT-45 metabolites displayed negligible potencies as mu receptor agonists, but one, 1,2-diphenylethylpiperazine, inhibited the NMDA receptor with an IC50 of 29 mu M. Conclusion and Implications Fluorinated derivatives of MT-45 are potent mu receptor agonists and this may pose a danger to illicit opioid users. Inhibition of NMDA receptors by a metabolite of MT-45 may contribute to the reported dissociative effects.

Synthesis and SAR of a series of mGlu(7) NAMs based on an ethyl-8-methoxy-4-(4-phenylpiperazin-1-yl)quinoline carboxylate core

A High-Throughput Screening (HTS) campaign identified a fundamentally new mGlu(7) NAM chemotype, based on an ethyl-8-methoxy-4-(4-phenylpiperazin-1-yl)quinolone carboxylate core. The initial hit, VU0226390, was a potent mGlu(7) NAM (IC50 = 647 nM, 6% L-AP4 min) with selectivity versus the other group III mGlu receptors (> 30 mu M vs. mGlu4 and mGlu8). A multi-dimensional optimization effort surveyed all regions of this new chemotype, and found very steep SAR, reminiscent of allosteric modulators, and unexpected piperazine mimetics (whereas classical bioisosteres failed). While mGlu(7) NAM potency could be improved (IC(50)s similar to 350 nM), the necessity of the ethyl ester moiety and poor physiochemical and DMPK properties precluded optimization towards in vivo tool compounds or clinical candidates. Still, this hit-to-lead campaign afforded key medicinal chemistry insights and new opportunities.

CO2 Heat of Absorption in Aqueous Solutions of MDEA and MDEA/Piperazine

In the present study, calorimetric measurements were conducted to determine CO2 behavior in aqueous solutions of 30 and 50 wt % N-methyl diethanolamine (MDEA) and 40 + 10 wt % MDEA-piperazine (PZ) at 323.15 and 353.15 K at pressures from 0.5 to 4 MPa. The effects of temperature, pressure, MDEA concentration, and addition of PZ on the heat of absorption and CO, solubility were investigated based on the calorimetric results, which were verified to be consistent with the vapor-liquid equilibrium data. No apparent effect of MDEA concentration was observed, while the heat of absorption was influenced by the temperature and pressure. The heat of absorption of the solution with PZ was enhanced, but the enhancement decreased with the increase of CO2 loading. The CO2 solubilities in aqueous solutions of 50 wt % MDEA and 40 + 10 wt % MDEA-PZ were compared in the experimental range, and the results showed no effect of PZ on the CO2 capture capacity. In addition, the absorption processes with and without PZ were simulated using Aspen Plus on the basis of the electrolyte non-random two-liquid model and a further study on the effect of the composition of MDEA and PZ in the solution was also conducted. The reaction mechanism was derived to give insights into the contribution of all reactions to the integral heat of absorption.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 16153-81-4. HPLC of Formula: C11H17N3.

Synthesis and Influence of 3-Amino Benzoxaboroles Structure on Their Activity against Candida albicans

Benzoxaboroles emerged recently as molecules of high medicinal potential with Kerydin(R) (Tavaborole) and Eucrisa(R) (Crisaborole) currently in clinical practice as antifungal and anti-inflammatory drugs, respectively. Over a dozen of 3-amino benzoxaboroles, including Tavaborole’s derivatives, have been synthetized and characterized in terms of their activity against Candida albicans as a model pathogenic fungus. The studied compounds broaden considerably the structural diversity of reported benzoxaboroles, enabling determination of the influence of the introduction of a heterocyclic amine, a fluorine substituent as well as the formyl group on antifungal activity of those compounds. The determined zones of the growth inhibition of examined microorganism indicate high diffusion of majority of the studied compounds within the applied media as well as their reasonable activity. The Minimum Inhibitory Concentration (MIC) values show that the introduction of an amine substituent in position 3 of the benzoxaborole heterocyclic ring results in a considerable drop in activity in comparison with Tavaborole (AN2690) as well as unsubstituted benzoxaborole (AN2679). In all studied cases the presence of a fluorine substituent at position para to the boron atom results in lower MIC values (higher activity). Interestingly, introduction of a fluorine substituent in the more distant piperazine phenyl ring does not influence MIC values. As determined by X-ray studies, introduction of a formyl group in proximity of the boron atom results in a considerable change of the boronic group geometry. The presence of a formyl group next to the benzoxaborole unit is also detrimental for activity against Candida albicans.

Water-stable metal-organic framework/amine-modified silica/poly (piperazine-cresol) hybrids for efficient uptake of La(III) ions

Hybrid nanocomposites of polymers and metal organic frameworks (MOFs) are characterized by distinctive surface activity due to high surface area of MOFs, excellent carrier nature and good thermal stability polymers. The combined two materials are expected to perform unusual performance in adsorptive removal and extraction processes. Therefore, microporous MOFs/polymer hybrid nanocomposite, Zn(Glu)-SiNH/PPC, has been synthesized by direct linking between silica-amine modified MOFs (Zn(Glu)-SiNH2) with poly(piperazine-cresol) (PPC) via microwave irradiation heating. Characterizations of Zn(Glu)-SiNH/PPC hybrid nanocomposite were explored by various techniques as XRD, surface area, SEM, TEM, and FT-IR. Lanthanum (III) ion was chosen as an example of the lanthanides series to investigate its adsorption activity by Zn(Glu)-SiNH/PPC hybrid nanocomposite. The maximum uptake capacity (15023.0 mu mol g(-1)) was established under the optimum conditions (pH 7.0, 20 min and 5 mg of Zn(Glu)-SiNH/PPC). The recognized equilibrium data of La(III) adsorption onto Zn(Glu)-SiNH/PPC hybrid nanocomposite were well explained by the Langmuir model. Additionally, the kinetics study was fitted satisfactorily with the pseudo-second order model. The recovery of La(III) ions from water samples (tap, sea and waste) were recognized as 98.23, 98.28 and 99.66%, respectively.

Preparation and characterization of TFC NF membrane with improved acid resistance behavior

In this study, we prepared the novel acid-resistant thin-film composite (TFC) piperazine(PIP)-based nanofiltration (NF) membrane using melamine (Mel), sulfonated-melamine formaldehyde (SMF), and sulfanilamide (SA) through interfacial polymerization on a polysulfone (PSf) support layer. A long-term acid-resistant experiment for divalent salt was carried out with static immersion tests in a 15 wt% sulfuric acid solution. The divalent rejection of the PIP1-SMF0.3-SA(0.05) in a 15 wt% sulfuric acid solution was maintained at over 96% after 10 days, and then slightly decreased to 94% for 20 days, and finally was maintained over 90% for 30 days. The flux was maintained at about 20 GFD even after 30 days of immersion in acid. In order to confirm the degree of hydrolysis in amide, the bond dissociation energy (BDE) was calculated using the density functional theory (DFT). BDE values of PIP-TMC, Mel-TMC, and SA-TMC were 79.34, 83.78, and 93.91 kcal/mol. Consequently, PIP1-SMF0.3-SA(0.05) having s-triazine and sulfonyl amide group exhibited acid-stable performance because the C-N bond is more stable and the slow hydrolysis reaction in acid. Our research for preparing high perm-selectivity and long-term acid stability membrane can extend NF technology in many industries, particularly in the recovery of rare metals from acidic solutions.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 16153-81-4, you can contact me at any time and look forward to more communication. Name: 4-(4-Methylpiperazin-1-yl)phenylamine.
