Novel 4,6-Disubstituted s-Triazin-2-yl Amino Acid Derivatives as Promising Antifungal Agents

A novel series of 4,6-disubstituted s-triazin-2-yl amino acid derivatives was prepared and characterized. Most of them showed antifungal activity against Candida albicans compared to clotrimazole (standard drug). Compounds bearing aniline derivatives, piperidine and glycine on the triazine core showed the highest inhibition zones at concentrations of 50, 100, 200, and 300 mu g per disc. In addition, docking studies revealed that all the compounds accommodated well in the active site residues of N-myristoltransferase (NMT) and exhibited complementarity, which explains the observed antifungal activity. Interestingly, none of these compounds showed antibacterial activity.

Transition-Metal-Free Total Synthesis and Revision of the Absolute Configuration of Pipermethystine

Starting from 3-hydroxy piperidines, a novel transition-metal-free strategy to 5-hydroxy-5,6-dihydro-2(1H)pyridones is reported. This unprecedented approach, which provides a practical, economical, and ecofriendly alternative to either the classical ring-closing metathesis of N-homoallyl-unsaturated amides or the dehydrogenation of amides, occurs by means of a triple C-H functionalization of three unreactive piperidine sp(3) carbons. The completion of the total synthesis revealed that the natural levoisomer possesses the R absolute configuration, not S.

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.

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.

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.

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.

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.

Deconstructive diversification of cyclic amines

Deconstructive functionalization involves carbon-carbon (C-C) bond cleavage followed by bond construction on one or more of the constituent carbons. For example, ozonolysis(1) and olefin metathesis(2,3) have allowed each carbon in C=C double bonds to be viewed as a functional group. Despite the substantial advances in deconstructive functionalization involving the scission of C=C double bonds, there are very few methods that achieve C(sp(3))-C(sp(3)) single-bond cleavage and functionalization, especially in relatively unstrained cyclic systems. Here we report a deconstructive strategy to transform saturated nitrogen heterocycles such as piperidines and pyrrolidines, which are important moieties in bioactive molecules, into halogen-containing acyclic amine derivatives through sequential C(sp(3))-N and C(sp(3))-C(sp(3)) single-bond cleavage followed by C(sp(3))-halogen bond formation. The resulting acyclic haloamines are versatile intermediates that can be transformed into various structural motifs through substitution reactions. In this way we achieve the skeletal remodelling of cyclic amines, an example of scaffold hopping. We demonstrate this deconstructive strategy by the late-stage diversification of proline-containing peptides.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 22990-77-8. The above is the message from the blog manager. Recommanded Product: 22990-77-8.

A Novel Highly Sensitive Method for Measuring Inflammatory Neural-Derived APC Activity in Glial Cell Lines, Mouse Brain and Human CSF

Background: Neural inflammation is linked to coagulation. Low levels of thrombin have a neuroprotective effect, mediated by activated protein C (APC). We describe a sensitive novel method for the measurement of APC activity at the low concentrations found in neural tissue. Methods: APC activity was measured using a fluorogenic substrate, Pyr-Pro-Arg-AMC, cleaved preferentially by APC. Selectivity was assessed using specific inhibitors and activators. APC levels were measured in human plasma, in glia cell lines, in mice brain slices following mild traumatic brain injury (mTBI) and systemic lipopolysaccharide (LPS) injection, and in cerebrospinal fluid (CSF) taken from viral meningoencephalitis patients and controls. Results: Selectivity required apixaban and alpha-naphthylsulphonylglycyl-4-amidinophenylalanine piperidine (NAPAP). APC levels were easily measurable in plasma and were significantly increased by Protac and CaCl2. APC activity was significantly higher in the microglial compared to astrocytic cell line and specifically lowered by LPS. Brain APC levels were higher in posterior regions and increased by mTBI and LPS. Highly elevated APC activity was measured in viral meningoencephalitis patients CSF. Conclusions: This method is selective and sensitive for the measurement of APC activity that significantly changes during inflammation in cell lines, animal models and human CSF.

Biomarker Profiling for Pyridoxine Dependent Epilepsy in Dried Blood Spots by HILIC-ESI-MS

Pyridoxine dependent epilepsy is a condition where the affected infant or child has prolonged seizures (status epilepticus), which are nonresponsive to anticonvulsant therapy but can be treated with pharmacological doses of pyridoxine. If identified earlier and treated prophylactically with pyridoxine, severe brain damage due to seizures can be prevented. Alpha-amino adipic semialdehyde (AASA), piperidine-6-carboxylic acid (P6C), and pipecolic acid (PA) are known biomarkers of pyridoxine dependent epilepsy. We report the development and validation of a hydrophilic interaction liquid chromatography (HILIC) hyphenated with mass spectroscopy for the quantification of the above analytes from dried blood spot samples. The samples were extracted using methanol and analysed on a iHILIC fusion plus column with formic acid buffer (pH 2.5): acetonitrilc (20:80) at a flow rate of 0.5 mL/min within 3 minutes. The method demonstrated a LOD of 10 ng/mL, LOQ of 50 ng/mL, linearity of r(2) >= 0.990, and recovery of 92-101.98% for all analytes. The intra- and interday precision CVs were < 8% and 6%, respectively. Extensive stability studies demonstrated that the analytes were stable in stock solution and in matrix when stored at -80 degrees C. We performed method comparison studies of the developed method with the literature reported method using normal samples and matrix matched spiked samples at pathological concentrations to mimic clinical validity. The Bland-Altman analysis for comparison of the analytical suitability of the method for the biomarkers in healthy and spiked samples with the literature reported method revealed a bias which suggested that the method was comparable. The newly developed method involves no derivatisation and has a simple sample preparation and a low run time enabling it to be easily automated with a high sample throughput in a cost-effective manner.
