Novel Piperidine and 3,4-dihydro-2H-pyrrole Alkaloids from Tilia platyphyllos and Tilia cordata Flowers

Lime flowers, traditionally used for medical purposes for the treatment of symptoms of the common cold and mental stress, consist of the dried inflorescences including the floral bracts of Tilia cordata, Tilia platyphyllos, Tilia x vulgaris, ormixtures thereof. During phytochemical investigations, 6 different alkaloids-not described until now-were detected in T. cordata and T. platyphyllos flowers. They have been isolated and characterized as alkaloids with a dihydro-pyrrole and a piperidine substructure, respectively. Compounds 1a and 1b (tiliines A and B) are characterized as 2 diastereomers containing a 2-methyl-3,4-dihydro-2H-pyrrol-3-ol, connected via a C10 alkyl chain to a O-glucosylated hydroquinone moiety. Compounds 2a and 2b (tiliamines A and B) are diastereomers of a 2-methyl-substituted piperidin-3-ol, coupled via a C-9 alkyl chain again to an O-glucosylated hydroquinone moiety. Compounds 3a and 3b (tilacetines A and B) are 3-O-acetylated derivatives of tiliamines. Quantification of the 6 alkaloids by HPLC-ESI-qTOF analysis indicated the presence of all alkaloids in T. cordata flowers and T. platyphyllos flowers, bracts, and leaves, with tiliines A and B and tilacetines A and B being the major compounds. Acetone/water turned out be the best extraction solvent for the alkaloids, but ethanol and ethanol/water mixtures also can be used for effective extraction. Furthermore, the alkaloids are found in hot water extracts, which are typically used in the traditional medicine.

Comparative Transcriptome Analysis of Key Reductase Genes Involved in the 1-Deoxynojirimycin Biosynthetic Pathway in Mulberry Leaves and Cloning, Prokaryotic Expression, and Functional Analysis of MaSDR1 and MaSDR2

The alkaloid 1-deoxynojirimycin (DNJ) is the main bioactive ingredient in the hypoglycemic action of mulberry leaves (Morus alba L.). Our previous research clarified the upstream pathway from lysine to Delta 1-piperideine in the biosynthesis of DNJ in mulberry leaves, but the pathway and related reductase genes from Delta 1-piperideine to piperidine are still unclear. Here, a comparative transcriptome was used to analyze the transcriptome data of two samples (July and November) of mulberry leaves with significant differences in the content of DNJ and screen-related reductase genes. Results showed that expression levels of MaSDR1 and MaSDR2 were significantly and positively correlated with the content of DNJ (P < 0.05) in different seasons. MaSDR1 (GenBank accession no. MT989445) and MaSDR2 (GenBank accession no. MT989446) were successfully cloned and used for prokaryotic expression and functional analysis in vitro. MaSDR1 and MaSDR2 could catalyze the reaction of Delta 1-piperideine with the coenzyme NADPH to generate piperidine. The kinetic parameters of MaSDR1 and MaSDR2 indicated that MaSDR2 had a higher binding ability to Delta 1-piperideine than MaSDR1. This study provided insights into the biosynthesis of DNJ in mulberry leaves. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 119515-38-7. HPLC of Formula: C12H23NO3.

A Highly Divergent Synthesis of 3-Aminotetrahydropyridines

Dihapto-coordinate 1,2-dihydropyridine complexes of the metal fragment {WTp(NO)(PMe3)} (Tp = tris(pyrazolyl)borate), derived from pyridine, are demonstrated to undergo protonation at C6 followed by regioselective amination at C5 with a variety of primary and secondary amines. The addition takes place stereoselectively anti to the metal center, producing exclusively cis-disubstituted products. The resulting 1,2,5,6-tetrahydropyridines can be successfully liberated by oxidation, providing a route to novel molecules of potential medicinal interest.

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?

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.

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.
