Design and green synthesis of 1-(4-ferrocenylbutyl)piperazine chemically grafted reduced graphene oxide for supercapacitor application

In this paper, we report the green synthesis of 1-(4-ferrocenylbutyl)piperazine chemically grafted rGO (P.Fc/rGO) as a battery-type supercapacitor electrode material. For this purpose, initially, the ability of the aqueousDamsonfruit extract is investigated in the reduction reaction of graphene oxide (GO). 1-(4-ferrocenylbutyl)piperazine (P.Fc) is synthesizedvianucleophilic substitution reaction of piperazine with as-synthesized 4-chlorobutylferrocene. In continue, P. Fc is incorporated to GO by ring-opening reaction of epoxide groups on the GO surface. In the next step, the modified reduction method by aqueousDamsonfruit extract was used to prepare the P.Fc/rGO from P.Fc/GO. The prepared materials were characterized by various techniques including FT-IR, Uv-vis, XRD, SEM, EDX, and BET. N(2)adsorption-desorption data of P.Fc/rGO nanocomposite shows that the surface area is 37.746 m(2)g(-1). The capability of P.Fc/rGO nanocomposite for using as an energy storage electrode material in battery-type supercapacitor was examined by investigation of its electrochemical behavior by CV, EIS, and GCD measurements. The charge storage capacity of 1,102 mAh g(-1)is achieved at 2.5 A g(-1). This nanocomposite shows 89% retention of charge storage capacity after 2000 CV cycles.

Prediction of CO2 Mass Transfer Flux in Aqueous Amine Solutions Using Artificial Neural Networks

In the present research, neural networks were applied to predict mass transfer flux of CO2 in aqueous amine solutions. Buckingham pi theorem was used to determine the effective dimensionless parameters on CO2 mass transfer flux in reactive separation processes. The dimensionless parameters including CO2 loading, ratio of CO2 diffusion coefficient of gas to liquid, ratio of the CO2 partial pressure to the total pressure, ratio of film thickness of gas to liquid and film parameter as input variables and mass transfer flux of CO2 as output variables were in the modeling. Multilayer perceptron network was used in the prediction of CO2 mass transfer flux. As a case study, experimental data of CO2 absorption into Piperazine solutions was used in the learning, testing and evaluating steps of the multilayer perceptron. The optimal structure of the multilayer perceptron contains 21 and 17 neurons in two hidden layers. The predicting results of the network indicated that the mean square error for mass transfer flux was 4.48%. In addition, the results of the multilayer perceptron were compared with the predictions of other researchers’ results. The findings revealed that the artificial neural network computes the mass transfer flux of CO2 more accurately and more quickly.

Novelpiperazine-tailoredursolic acid hybrids as significant antibacterial agents targeting phytopathogensXanthomonas oryzaepv.oryzaeandX. axonopodispv.citriprobably directed by activation of apoptosis

BACKGROUND Induced apoptosis is an effective technique that can reprogram cellular physiological and pathological processes to eradicate undesirable cells using their innate systems. Inspired by this, numerous apoptosis inducers have been developed to treat animal diseases, especially in the anticancer field. However, few studies have reported on the development of inductive agents that attack plant pathogens by activation of apoptosis. With the aim of exploring and discovering apoptosis inducers that target phytopathogens, a cluster of piperazine-tailored ursolic acid (UA) hybrids was systematically fabricated. RESULTS In vitrotesting showed that the title molecules could inhibit the growth of two intractable bacterial strains, defined asXanthomonas oryzaepv.oryzaeandX. axonopodispv.citri. The corresponding lowest EC(50)values were 0.37 and 1.08 mu g mL(-1), which exceed those of UA (>400 mu g mL(-1)) and positive controls. Moreover, compounds5uand5vcould manage bacterial blightin vivousing pot experiments. Flow cytometer analysis indicted that the title compounds could induce distinct apoptotic behaviors on tested bacteria. In-depth study revealed that the introduction of designed compounds could reduce the enzyme activities of catalase and superoxide dismutase, subsequently leading to the accumulation of reactive oxygen species. CONCLUSION This study promoted the development of apoptosis initiators for managing bacterial infections in agriculture by an innovative mode of action. (c) 2020 Society of Chemical Industry

Ecofriendly Validated Chromatographic Methods for Quantitation of Cyclizine and Its Toxic Impurities in Its Parenteral Formulation

Cyclizine (CYZ) abuse is commonly reported, either through oral or intravenous routes, for its euphoric or hallucinatory effects. The concomitant misuse of CYZ among addicted teenagers leads to life-threatening neuromuscular disorders. Consequently, two green and validated chromatographic methods were developed for the determination of CYZ, an antiemetic drug, in its parenteral formulation in the presence of 1-methyl piperazine and diphenylmethanol (benzhydrol) as the pharmacopeial stated impurities of CYZ. The first method was TLC-densitometry that relied on using a mixture consisting of ethyl acetate:isopropanol:ammonia (9.5:1:0.5, by volume) as a developing system, TLC 60 F-254 silica gel plates as a stationary phase and detection of the scanned bands was performed at 210.0 nm. On the other hand, the second method was UPLC which based on the separation of CYZ and its impurities using a mobile phase consisting of ethanol and acidic water at pH 5 adjusted by phosphoric acid in the ratio of (60:40, %v/v) at flow rate 0.2 mL min(-1) and UV detection were carried out at 210.0 nm. The greenness profile of the established methods was evaluated and calculated for the first time for CYZ and its toxic impurities through different assessment tools like analytical eco-scale, analytical method volume intensity and greenness profile methods. Validation of the developed methods was carried out in accordance with the guidelines of the International Conference on Harmonization. The suggested methods were accurate, reliable, time and cost-saving. Therefore, they could be used in quantification of CYZ abuse and its toxic impurities in parenteral formulation for routine quality control. The results achieved by applying the suggested methods were statistically analyzed and compared with those given by reported one and no significant differences were obtained regarding both precision and accuracy.

Energy Minimization in Piperazine Promoted MDEA-Based CO2 Capture Process

A piperazine (PZ)-promoted methyldiethanolamine (MDEA) solution for a carbon dioxide (CO2) removal process from the flue gas of a large-scale coal power plant has been simulated. An Aspen Plus was used to perform the simulation process. Initially, the effects of MDEA/PZ concentration ratio and stripper pressure on the regeneration energy of CO2 capture process were investigated. The MDEA/PZ concentration ratio of 35/15 wt.% (35 wt. MDEA and 15 wt.% PZ) was selected as an appropriate concentration. The reboiler duty of 3.235 MJ/kg CO2 was obtained at 35/15 wt.% concentration ratio of MDEA/PZ. It was considered a reference or base case, and process modifications including rich vapor compression (RVC) process, cold solvent split (CSS), and the combination of both processes were investigated to check its effect on the energy requirement. A total equivalent work of 0.7 MJ(e)/kg CO2 in the RVC and a reboiler duty of 2.78 MJ/kg CO2 was achieved in the CSS process. Similarly, the total equivalent work, reboiler duty, and condenser duty of 0.627 MJ(e)/kg CO2, 2.44 MJ/kg CO2, and 0.33 MJ/kg CO2, respectively, were obtained in the combined process. The reboiler duty and the total equivalent work were reduced by about 24.6 and 16.2%, respectively, as compared to the reference case. The total energy cost saving was 1.79 M$/yr. Considering the additional equipment cost in the combined process, the total cost saving was 0.67 M$ per year.

The antidepressant-like activity of chiral xanthone derivatives may be mediated by 5-HT1A receptor and beta-arrestin signalling

Background: Our previous studies showed that xanthone derivatives with N-(2-methoxyphenyl)piperazine fragment have an affinity to the 5-HT1A receptor and show antidepressant-like properties in rodents. In this study, we tested three xanthone derivatives, HBK-1 (R, S) and its enantiomers, in which we increased the distance between the piperazine and xanthone fragments by using a hydroxypropoxy linker. We hypothesized that this would increase the binding to the 5-HT1A receptor and consequently, pharmacological activity. Aims: We aimed to assess the in vitro and in vivo pharmacological activity of the xanthone derivatives. Methods: We evaluated the in vitro affinity for serotonin 5-HT1A and 5-HT2A receptors and serotonin transporter. We also determined the intrinsic activity at the 5-HT1A receptor. We investigated the antidepressant-like properties and safety after acute administration (dose range: 1.25-20 mg/kg) using the forced swim, tail suspension, locomotor activity, rotarod and chimney tests in mice. We also evaluated the basic pharmacokinetic parameters. Results: Our results indicated that the compounds showed a high affinity for the 5-HT1A receptor but very weak antagonistic properties in the Ca2+ mobilization assay; however, they showed significant agonistic properties in the beta-arrestin recruitment assay. In both behavioural tests the studied xanthone derivatives showed antidepressant-like activity. Pre-treatment with p-chlorophenylalanine or WAY-100635 abolished their antidepressant-like activity. None of the compounds caused motor impairments at antidepressant-like doses. The racemate penetrated the blood-brain barrier and had a relatively high bioavailability after intraperitoneal administration. Conclusions: Xanthone derivatives with N-(2-methoxyphenyl)piperazine fragment and hydroxypropoxy linker show increased binding to the 5-HT1A receptor and may represent an attractive putative treatment candidate for depression.

Prodrugs for nitroreductase based cancer therapy-4: Towards prostate cancer targeting: Synthesis of N-heterocyclic nitro prodrugs, Ssap-NtrB enzymatic activation and anticancer evaluation

In this study, various N-heterocyclic nitro prodrugs (NHN1-16) containing pyrimidine, triazine and piperazine rings were designed and synthesized. The final compounds were identified using FT-IR, H-1 NMR, C-13 NMR as well as elemental analyses. Enzymatic activities of compounds were conducted by using HPLC analysis to investigate the interaction of substrates with Ssap-NtrB nitroreductase enzyme. MTT assay was performed to evaluate the toxic effect of compounds against Hep3B and PC3 cancer cell lines and healthy HUVEC cell. It was observed that synthesized compounds NHN1-16 exhibited different cytotoxic profiles. Pyrimidine derivative NHN3 and triazine derivative NHN5 can be good drug candidates for prostate cancer with IC50 values of 54.75 mu M and 48.9 mu M, respectively. Compounds NHN6, NHN10, NHN12, NHN14 and NHN16 were selected as prodrug candidates because of non-toxic properties against three different cell models. The NHN prodrugs and Ssap-NtrB combinations were applied to SRB assay to reveal the prodrug capabilities of these selected compounds. SRB screening results showed that the metabolites of all selected non-toxic compounds showed remarkable cytotoxicity with IC50 values in the range of 1.71-4.72 nM on prostate cancer. Among the tested compounds, especially piperazine derivatives NHN12 and NHN14 showed significant toxic effect with IC50 values of 1.75 nM and 1.79 nM against PC3 cell compared with standart prodrug CB1954 (IC50: 1.71 nM). Novel compounds NHN12 and NHN14 can be considered as promising prodrug candidates for nitroreductase-prodrug based prostate cancer therapy.

Structural elucidation of Levofloxacin and Ciprofloxacin using density functional theory and Raman spectroscopy with inexpensive lab-built setup

In the present work, we have investigated the structures of fluoroquinolones Levofloxacin and Ciprofloxacin using Raman spectroscopy and density functional theory calculations. The Raman spectra of Levofloxacin and Ciprofloxacin were recorded with lab-built inexpensive Raman spectroscopy setup that uses 638 nm laser diode. Raman spectra in the fingerprint spectral region (900-1800 cm(-1)) were investigated for both the molecules. The density functional theory (DFT) utilizing B3LYP functional with 6-31+G(d,p) basis set was used to investigate the minimum energy structures of two molecules along with the calculation of Raman spectrum. Molecular complexes of Levofloxacin and Ciprofloxacin with one and two water molecules were also studied to see the effect of H-bonding on Raman spectra. It was found that the conformation and orientation of piperazine ring along with the orientation of hydroxyl group plays a vital role in determination of the minimum energy structure. The calculated Raman spectra of bare molecules and their complexes with water molecules were compared to the experimental Raman spectra. The calculated Raman spectrum of minimum energy structure was found to be in good agreement with the experimental spectrum. Further it was observed that the experimental Raman spectrum is better explained when H-bonding is considered, which could be due to the water molecule or the dimer formation of the molecules under investigation.

5-HT1A targeting PARCEST agent DO3AM-MPP with potential for receptor imaging: Synthesis, physico-chemical and MR studies

Contrast enhancement in MRI using magnetization or saturation transfer techniques promises better sensitivity, and faster acquisition compared to T-1 or T-2 contrast. This work reports the synthesis and evaluation of 5-HT1A targeted PARACEST MRI contrast agent using 1,4,7,10-tetraazacycloDOdecane-4,7,10-triacetAMide (DO3AM) as the bifunctional chelator, and 5-HT1A-antagonist methoxyphenyl piperazine (MPP) as a targeting unit. The multistep synthesis led to the MPP conjugated DO3AM with 60% yield. CEST-related physicochemical parameters were evaluated after loading DO3AM-MPP with paramagnetic MRI active lanthanides: Gadolinium (Gd-DO3AM-MPP) and Europium (Eu-DO3AM-MPP). Luminescence lifetime measurements with Eu-DO3AM-MPP and computational DFT studies using Gd-DO3AM-MPP revealed the coordination of one water molecule (q = 1.43) with metal-water distance (r(M)-H2O) of 2.7 angstrom and water residence time (tau(m)) of 0.23 ms. The dissociation constant of K-d 62 +/- 0.02 pM as evaluated from fluorescence quenching of 5-HT1A (protein) and docking score of -4.81 in theoretical evaluation reflect the binding potential of the complex Gd-DO3AM-MPP with the receptor 5-HT1A. Insights of the docked pose reflect the importance of NH2 (amide) and aromatic ring in Gd-DO3AM-MPP while interacting with Ser 374 and Phe 370 in the antagonist binding pocket of 5-HT1A. Gd-DO3AM-MPP shows longitudinal relaxivity 5.85 mM(-1)s(-1) with a water residence lifetime of 0.93 ms in hippocampal homogenate containing 5-HT1A. The potentiometric titration of DO3AM-MPP showed strong selectivity for Gd3+ over physiological metal ions such as Zn2+ and Cu2+. The in vitro and in vivo studies confirmed the minimal cytotoxicity and presential binding of Gd-DO3AM-MPP with 5-HT1A receptor in the hippocampus region of the mice. Summarizing, the complex Gd-DO3AM-MPP can have a potential for CEST imaging of 5-HT1A receptors.

DNA Binding, DFT and Spectroscopic Studies of a Charge Transfer Complex Consisting of a Bioactive Donor 1-(2-Methylbenzyl)piperazine

A bioactive donor, 1-(2-methylbenzyl)piperazine is used to synthesize a new charge transfer complex (CTC) with the p-acceptor p-chloranil (p-CHL), which is characterized spectrophotometrically. The quantitative estimation of electronic interaction of the acceptor with the donor has been examined in acetonitrile (AN). The 1:1 composition of the CTC is confirmed by Jobs’ method of continuous variation and spectrophotometric (at max 554 nm) methods at 298 K. The Benesi-Hildebrand method gives the formation constant (KCT) and molar extinction coefficient (e) values of CTC. The spectral analysis was used to characterize CTC and its stability in solution and in the crystalline form. A DNA binding study of the CT-complex was carried out using UV-visible spectroscopy. A density functional theory (DFT) study of the CTC (gas phase/PCM) at using the B3LYP functional and 6-31G(d,p) basis set supports the experimental work. The optimization of the frontier molecular orbital surfaces was carried out by using the DFT-gasphase/PCM correlation methods. Mulliken atomic charges and reactive parameters of acceptor and donor recommend the MBPZ acts as a good electron donor and p-CHL acts as a good electron acceptor to form a highly stable electron transfer complex.
