Evaluation of Cytotoxic Properties of N,N’-bis[(1-aryl-3-heteroaryl)propylidene]-hydrazine dihydrochlorides

N,N’-bis[(1-aryl-3-heteroaryl)propylidene]hydrazine dihydrochlorides, P1, P4 – P8, and R1 – R7, were assayed against human oral squamous cell carcinoma (HSC-2, HSC-3, HSC-4), human promyelocytic leukemia cell line (HL-60), and human normal oral cells (HGF, HPC, and HPLF) as non-tumor cells to evaluate their cytotoxic properties. Peplomycin was used as a reference compound. It was found that P- and R-series hydrazone compounds exhibited cytotoxicity in a range of 11 +/- 0.68 – 300 +/- 1.0 +/- M. Compound P1 which is a non-substituted hydrazone containing piperidine ring and compound R2 which is a 4-methyl hydrazone derivative containing pyrrolidine ring showed the most potent cytotoxic activity. These hydrazone compounds may serve as promising candidates for further studies.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 106-52-5 help many people in the next few years. Category: piperidines.

Multi-targeted drug design strategies for the treatment of schizophrenia

Introduction Schizophrenia is a complex psychiatric disease (or a conglomeration of disorders) manifesting with positive, negative and cognitive symptoms. The pathophysiology of schizophrenia is not completely known; however, it involves many neurotransmitters and their receptors. In order to treat schizophrenia, drugs need to be multi-target drugs. Indeed, the action of second and third generation antipsychotics involves interactions with many receptors, belonging mainly to aminergic GPCRs. Areas covered In this review, the authors summarize current concepts of schizophrenia with the emphasis on the modern dopaminergic, serotoninergic, and glutamatergic hypotheses. Next, they discuss treatments of the disease, stressing multi-target antipsychotics. They cover different aspects of design of multi-target ligands, including the application of molecular modeling approaches for the design and benefits and limitations of multifunctional compounds. Finally, they present successful case studies of multi-target drug design against schizophrenia. Expert opinion Treatment of schizophrenia requires the application of multi-target drugs. While designing single target drugs is relatively easy, designing multifunctional compounds is a challenge due to the necessity to balance the affinity to many targets, while avoiding promiscuity and the problems with drug-likeness. Multi-target drugs bring many benefits: better efficiency, fewer adverse effects, and drug-drug interactions and better patient compliance to drug regime.

A binuclear chloride bridged Cu(II) and a mononuclear Ni(II) complex: Synthesis, crystal structure, photo catalytic and biological studies

In the present paper, one new binuclear chloride bridged Cu(II) complex [Cl2Cu-(mu-Cl)-Cu(L)Cl-2] (1) and one mononuclear Ni(II) complex [Ni(L ‘)(2)](ClO4)(2) (2) where L = N-1-(pyridine-2-ylmethylene)-N-2-(2-(pyridine-2-ylmethyleneamino)ethyl)ethane-1,2-diamine derived from pyridine-2-aldehyde and diethylenetriamine, L’ = Piperidine-2-yl-N-(pyridine-2-ylmethylene)methanamine derived from pyridine-2-aldehyde and 2-aminomethylpiperidine have been synthesized and characterized by single crystal X-ray diffraction studies. The crystal structure of the binuclear Cu(II) complex (1) shows that the two square pyramidal Cu(II) moieties are joined through a single chloride (mu-Cl) bridge and the coordination environment around the two copper atoms are same, whereas the nickel ion in complex (2) has an octahedral geometry. The antibacterial study for metal salts, ligands and complexes were performed using Staphylococcus aureus. The result shows that among the complexes, complex (2) exhibits better antibacterial properties than complex (1). Optical band gaps of 3.3 and 3.1 eV for complexes 1 and 2 respectively reveal that both the complexes have some semiconducting properties. Photo catalytic activity and H2O2 sensing activity for both the complexes were also determined. The photo catalytic test was performed against Rhodamine B (RB), Methylene Blue (MB), Malachite Green (MG) and Bromocressol Green (BG) in presence of sunlight. Results of photo catalytic and H2O2 sensing tests have revealed that both the complexes have degradation ability against each dye but complex 1 have only H2O2 sensing properties. DNA binding ability of the complexes was done by absorption titration, ethidium bromide displacement and viscosity measurement studies. Furthermore, molecular docking studies for complex 2 were also performed with B-DNA model sequence. It has been shown that complex 2 interacts with DNA through partial intercalation as well as minor-groove binding. The cell viable activity of the ligand, copper and nickel complexes were measured in vitro against the Hela cell and it shows that the metal complexes are biocompatible in nature. So the utility of this study is that the complexes under investigation can effectively be used as pharmaceutical components in several antibacterial drugs as they are biocompatible in nature and can also be used in waste dye degradation or separation process from water or to detect H2O2 widely used in food, cosmetic, pharmaceutical and paper industries.

Synthesis, vibrational spectra, DFT calculations, Hirshfeld surface analysis and molecular docking study of 3-chloro-3-methyl-2,6-diphenylpiperidin-4-one

A newly synthesized molecular complex 3-chloro-3-methyl-2,6-diphenylpiperidin-4-one [CMDP] crystallizes in the triclinic space group Pl. The pipe ridin-4-one ring exhibits a distorted chair conformation with the puckering parameters Q= 0.559 (3) angstrom. theta = 173.3 (3 degrees) and phi = 180 (2 degrees). The methyl substituent on the third position of the piperidine ring takes up a syn-periplanar positioning although the chioro substituent takes up an anti-clinical positioning with dihedral angle: Cl1-C2-C1-O1 = 1133 (2 degrees) due to the repulsion from an adjacent oxygen atom. The optimized molecular geometry and fundamental vibrational frequencies of the CMDP compounds are interpreted with the help of normal coordinate force field calculations based on DFT method B3LYP/6-31-i-G (d,p) level basis set. The HOMO-LUMO energy gap of the molecule is 5.4194 eV. The hardness value (eta) of the CMDP molecule is 2.7097 eV. Hirshfeld surface analysis and fingerprint plots are supportive for determining the molecular shape and visually analyzing the intermolecular interactions in the crystal structure. The Hirshfeld surfaces like d(i), d(e). d(norm), shape index and curvedness of C18H18NOCl were pictured and discussed. The various levels of electronic transitions have been predicted by Time-Dependent Density Functional Theory (TD-DFT) calculations and compared with the recorded absorption spectrum. Molecular docking study was performed and reported for the synthesized compound against 4ey7 protein. (C) 2020 Elsevier B.V. All rights reserved.

Recent developments in the synthesis of prosophylline and its derivatives

Several synthetic efforts are reported towards the optically active (-)-prosophylline and (+)-prosophylline, and their derivatives. Interestingly and surprisingly, although only a few synthesis are reported for the parent molecules, there are more reports for the synthesis of their derivatives such as deoxoprosophyllines, deoxoprosopinines, deoxocassines etc. The three main strategies to procure these molecules in optically pure forms are by using (i) chiral synthons (ii) chiral auxiliaries and (iii) asymmetric catalysis. Among these, the chiral synthons are mainly utilized by a number of researchers. This review summarizes the recent developments in the synthesis of optically active prosophyllines and their derivatives, and covers the literature from the year 2000 onwards.

Characterization and cytotoxic activity on glial cells of alkaloid-enriched extracts from pods of the plants Prosopis flexuosa and Prosopis nigra (Fabaceae)

Introduction: Prosopis spp. pods have shown to be a potential source of protein and energy in livestock. However, prolonged ingestion of some of these species produces neurological symptoms in ruminants. Objective: In the present study, the alkaloid content and the in vitro neurotoxic activity of alkaloid enriched-extracts from P. flexuosa and P. nigra pods were determined in order to elucidate the mechanism of animal poisoning caused by these species. Methods: The main alkaloids present in both extracts were analysed by high performance liquid chromatography-high resolution mass spectrometry (HPLC-HRMS). The cytotoxic activity of Prosopis alkaloid enriched-extracts in primary mixed glial cell culture was assessed by phase contrast microscopy and using neutral red, and lactate dehydrogenase (LDH) activity assays. Results: Juliprosine and juliprosopine were identified in P. flexuosa pods, while the absence of these alkaloids in P. nigra was confirmed. Both extracts (5-30 mu g/mL) induced in a dose dependent manner, morphological alterations, such as swelling, enlargement and detachment from the culture surface. Consistent with this, decrease in cell viability and release of LDH 48 hours after exposure, revealed that P. flexuosa pods was significantly more cytotoxic than P. nigra. Conclusions: In P. flexuosa pods, juliprosine and juliprosopine alkaloids were identified for the first time. Moreover, the present study suggests that the cytotoxic effect displayed by both extracts is due to its alkaloid content. However, the presence of piperidine alkaloids in P. flexuosa could explain the greater cytotoxicity on glial cells with respect to P. nigra that was not shown to contain these alkaloids.

Electrochemical Aminoxyl-Mediated alpha-Cyanation of Secondary Piperidines for Pharmaceutical Building Block Diversification

Secondary piperidines are ideal pharmaceutical building blocks owing to the prevalence of piperidines in commercial drugs. Here, we report an electrochemical method for cyanation of the heterocycle adjacent to nitrogen without requiring protection or substitution of the N-H bond. The reaction utilizes ABNO (9-azabicyclononane N-oxyl) as a catalytic mediator. Electrochemical oxidation of ABNO generates the corresponding oxoammonium species, which promotes dehydrogenation of the 2 piperidine to the cyclic imine, followed by addition of cyanide. The low-potential, mediated electrolysis process is compatible with a wide range of heterocyclic and oxidatively sensitive substituents on the piperidine ring and enables synthesis of unnatural amino acids.

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 4418-26-2. Quality Control of Sodium 3-acetyl-6-methyl-2,4-dioxo-3,4-dihydro-2H-pyran-3-ide.

Adjustment of the Al siting in MCM-22 zeolite and its effect on alkylation performance of ethylene with benzene

It may be an important route to improve the alkylation performance of MCM-22 zeolite by regulating the Al siting during the synthesis, as the liquid alkylation of benzene with ethylene mainly occur on the acid sites in the surface pockets and supercages of MCM-22. Here, the Al siting has been successfully adjusted by introducing additional anion in the hydrothermal synthesis of MCM-22 using piperidine as the structure directing agent. The effect of the additional anion in the synthesis precursor on the physiochemical property, especially the Al siting, and alkylation performance of MCM-22 zeolite was investigated. The morphology of products tends to be irregular lamellar structure when Cl-, PO43-, or SO42- are present in the synthesis gel. Although H-MCM-22-PO43- and H-MCM-22-SO42- show less acid site concentration than H-MCM-22, they exhibit obviously higher conversion of ethylene than H-MCM-22. This can be attributed to that more Al species are oriented to T-2 sites located in the pockets or supercages by virtue of the presence of PO43- or SO42- in the synthesis gel. The novel synthesis strategy may provide an alternative way to modify the performances of MCM-22 and even other zeolites.

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 10465-81-3. Computed Properties of C12H20N4O2.
