Cost-effective and handmade paper-based potentiometric sensing platform for piperidine determination

For the first time, a robust, rugged, and low-cost ion sensor based on potentiometric transduction is presented here for rapid determination of piperidine. A conventional filter paper is used as a substrate to establish the sensors after coating a carbon-ink layer on the surface of the filter paper to make it conductive. Poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) was used as an ion-to-electron transducer and deposited through drop-casting on the paper-based carbon electrode. The polymeric membranes were based on the incorporation of two types of electroactive materials, namely ion association complexes such as piperidinium phosphomolybdate (Pip/PMA) (sensor I), piperidinium phosphotungstate (Pip/PT) (sensor II), piperidinium tetraphenyl borate (Pip/TPB) (sensor III), and -cyclodextrin (-CD) ionophore (sensor IV) in a plasticized polyvinyl chloride (PVC) matrix. The sensors revealed Nernstian slopes of 60.2 +/- 0.5, 57.1 +/- 0.6, 56.2 +/- 0.8 and 54.2 +/- 0.6 mV per decade with linear concentration ranges begin from 5.1 x 10(-6), 7.4 x 10(-6), 3.1 x 10(-5) and 5.5 x 10(-6) M for sensors I, II, III and IV, respectively. The detection limits range from 0.32 to 0.66 g mL(-1) for all the proposed sensors with a response time <10 seconds. The sensors exhibited clear selectivity towards piperidinium ions over several common organic and inorganic cations. Repeatability, reproducibility and stability have been studied to evaluate the properties of the sensors. The sensors were successfully utilized for piperidine quantification in wastewater and human urine samples. The obtained results agreed well with the acceptable recovery percentage and were better than those obtained by other previously reported routine methods. Interested yet?

Identification of the metabolites of piperine via hepatocyte incubation and liquid chromatography combined with diode-array detection and high-resolution mass spectrometry

Rationale Piperine, an alkaloid isolated from Piper nigrum L., has been demonstrated to have many pharmacological effects and several health benefits. The aim of this work was to study the metabolic profiles of piperine in mouse, rat, dog and human hepatocytes. Methods The biotransformation was carried out by incubating piperine with hepatocytes at 37 degrees C. After incubation for 2 h, the samples were pretreated and analyzed using liquid chromatography combined with diode-array detection and high-resolution mass spectrometry (LC/DAD-HRMS). The structures of the metabolites were assigned through a comparison of their accurate masses and product ions with those of the parent compound. Results A total of 20 metabolites were detected, and the structures were proposed. Piperine was metabolized through the following pathways: (a) oxidation to form a catechol derivative, which further underwent methylation, glucuronidation, glutathione (GSH) conjugation, and hydroxylation followed by opening of the piperidine ring; (b) hydroxylation to form a carbinolamine intermediate followed by opening of the piperidine ring and the formation of alcohol and acid derivatives; and (c) hydroxylation to form stable hydroxylated metabolites. In mouse, the formation of the catechol derivative (M12) and hydroxylation (M11) were the major metabolic pathways; in rat, the formation of the catechol derivative (M12) and glucuronidation (M9) were the main pathways; and in dog and human, the formation of the catechol derivative (M12) was the predominant pathway. No human-specific metabolite was observed. Conclusions This study provided some new information on the metabolic profiles of piperine, which should be of great importance in the study of the pharmacology and toxicity of this compound.

Chemical Probing of Thymine in the TGG/CGG Triad to Explore the Deamination of 5-Methylcytosine in the CGG Repeat

The methylation of cytosine in the full mutation of the expanded CGG repeat and subsequent deamination to thymine could be a measure of repeat instability. We report the synthesis of NCD-Bpy, which binds to the TGG/CGG site in the repeat hairpin. NCD-Bpy forces the thymine in the TGG/CGG site to flip out from the Jr-stack, recruits osmium tetroxide in the vicinity of the flipped-out T, and oxidizes the T. The piperidine-induced cleavage band successfully determined the position of the T in the expanded CGG repeat.

Click-Addressable Cassette for Photoaffinity Labeling

A small molecule 1 was designed to contain an alkyne, a trifluoromethyl phenyldiazirine, and a free piperidine-NH for facile conjugation to protein binding ligands. This cassette 1 was synthesized via a relatively direct route involving only routine steps. In this proof-of-concept study, putative ligands for carbonic anhydrase IX and for TrkC were conjugated to 1. Photoaffinity labeling was performed using purified extracellular regions of both these protein-receptors, and using cells that express these receptors (isolation via a pull-down procedure), labeling of the protein was observed in all four experiments.

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 5570-77-4. COA of Formula: C6H12ClN.

Synthesis and Characterization of New Series of 1,3-5-Triazine Hydrazone Derivatives with Promising Antiproliferative Activity

A new series of s-triazine hydrazone derivatives was prepared based on the reaction of 6-hydrazino-2,4-disubstituted-s-triazine with p-substituted benzaldehyde derivatives using a straightforward synthetic pathway. The antiproliferative activity of all synthesized compounds was evaluated against two human cancer cell lines; breast cancer MCF-7 and colon carcinoma HCT-116 using MTT assay. Among all, 11 compounds have shown strong to moderate antiproliferative activity with IC50 values in the range 1.01-18.20 mu M in MCF-7 and 0.97-19.51 mu M in HCT-116. The best results were obtained with 4,4′-(6-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3,5-triazine-2,4-diyl) dimorpholine 11 (IC50 = 1.0 mu M and 0.98 mu M in MCF-7 and HCT-116 cell lines, respectively). The substituents on the s-triazine core as well as the substituent at the benzylidene moiety have a great effect on the antiproliferative activity. Whereas compounds containing dimorpholino-s-triazine derivatives 8a-e showed more potent antiproliferative in MCF-7 compared to their analogs 7a-f (compounds containing two-piperidine rings), compounds containing one piperidine and one morpholine ring 9a-f showed better IC50 values in the range 10.4-22.2 mu M. On the other hand, compounds containing two-piperidine rings 7a-f showed more potent antiproliferative in HCT-116 (IC50 values in the range 8.8-19.5 mu M) than their analogs 8a-e and 9a-f.

The identification and analytical characterization of 2,2 ‘-difluorofentanyl

New psychoactive substances (NPS) have expanded their distribution and become widely available in the global market in recent years. The illicit use of fentanyl and its analogs has become an important worldwide concern linked to their high potency and risk of fatal overdose. This study describes the analytical characterization of a new fentanyl derivative N-(1-(2-fluorophenethyl)-4-piperidinyl)-N-(2-fluorophenyl)propionamide (2,2-difluorofentanyl). Identification was based on ultra-high-performance liquid chromatography-quadrupole time-of-flight-mass spectrometry (UHPLC-QTOF-MS), gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared (FTIR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. To our knowledge, this study is the first to report on analytical data for this compound. The most abundant fragment ion in the electrospray ionization (ESI) mass spectrum under collision-induced dissociation (CID) mode was formed by the cleavage between the piperidine ring and the N-phenyl-amide moiety of the protonated molecule. Two diagnostic ions in the electron ionization (EI) mass spectrum were formed by the loss of a tropylium ion (M-91), and by the degradation of the piperidine ring and dissociate of the COC2H5 moiety altogether, respectively.

1,6-Dehydropinidine Is an Abundant Compound in Picea abies (Pinaceae) Sprouts and 1,6-Dehydropinidine Fraction Shows Antibacterial Activity against Streptococcus equi Subsp. equi

Knowledge about the defensive chemistry of coniferous trees has increased in recent years regarding a number of alkaloid compounds; in addition to phenolics and terpenes. Here, we show that Norway spruce (Picea abies (L.) H. Karst.), an important boreal zone tree species; accumulates 1,6-dehydropinidine (2-methyl-6-(2-propenyl)-1,6-piperideine) in its needles and bark. We reanalyzed previously published GC-MS data to obtain a full picture of 1,6-dehydropinidine in P. abies. 1,6-dehydropinidine appeared to especially accumulate in developing spring shoots. We used solid-phase partitioning to collect the alkaloid fraction of the sprouts and thin-layer chromatography to purify 1,6-dehydropinidine. The antibacterial properties of the 1,6-dehydropinidine fraction were tested using a broth microdilution method; with Streptococcus equi subsp. equi as a model organism. Based on our results 1,6-dehydropinidine is common in alkaloid extractions from P. abies (0.4 +/- 0.03 mg g(-1) dw in mature needles) and it is especially abundant in young spruce shoots (2.7 +/- 0.5 mg g(-1) dw). Moreover; 1,6-dehydropinidine extracted from P. abies sprouts showed mild antibacterial potential against Streptococcus equi subsp. equi (MIC 55 mu g mL(-1)). The antibacterial activity of a plant compound thought of as an intermediate rather than an end-product of biosynthesis calls for more detailed studies regarding the biological function of these coniferous alkaloids

Copper-ligand clusters dictate size of cyclized peptide formed during alkyne-azide cycloaddition on solid support

Peptide and peptidomimetic cyclization by copper-catalyzed alkyne-azide cycloaddition (CuAAC) reaction have been used to mimic disulfide bonds, alpha helices, amide bonds, and for one-bead-one-compound (OBOC) library development. A limited number of solid-supported CuAAC cyclization methods resulting in monomeric cyclic peptide formation have been reported for specific peptide sequences, but there exists no general study on monocyclic peptide formation using CuAAC cyclization. Since several cyclic peptides identified from an OBOC CuAAC cyclized library has been shown to have important biological applications, we discuss here an efficient method of alkyne-azide ‘click’ catalyzed monomeric cyclic peptide formation on a solid support. The reason behind the efficiency of the method is explored. CuAAC cyclization of a peptide sequence with azidolysine and propargylglycine is performed under various reaction conditions, with different catalysts, in the presence or absence of an organic base. The results indicate that piperidine plays a critical role in the reaction yield and monomeric cycle formation by coordinating to Cu and forming Cu-ligand clusters. A previously synthesized copper compound containing piperidine, [Cu4I4(pip)(4)], is found to catalyze the CuAAC cyclization of monomeric peptide effectively. The use of 1.5 equivalents of CuI and the use of DMF as solvent is found to give optimal CuAAC cyclized monomer yields. The effect of the peptide sequence and peptide length on monomer formation are also investigated by varying either parameter systemically. Peptide length is identified as the determining factor for whether the monomeric or dimeric cyclic peptide is the major product. For peptides with six, seven, or eight amino acids, the monomer is the major product from CuAAC cyclization. Longer and shorter peptides on cyclization show less monomer formation. CuAAC peptide cyclization of non-optimal peptide lengths such as pentamers is affected significantly by the amino acid sequence and give lower yields.
