A recent study on our metal-dithiocarbamato complexes pointed out the antiproliferative properties and the druglikeness of some new patented derivatives. In this work, the best compounds have been encapsulated in micellar nanocarriers, being also carbohydrate-functionalized on their hydrophilic surface to investigate the possibility of a cancer-selective delivery. In particular, the nonionic block copolymer Pluronic (R) F127 (PF127) has been chemically modified with sugars and the derivatives characterized by means of NMR spectroscopy and FT-IR spectrophotometry. Then, the two selected complexes (beta-[Ru-2(PipeDTC)(5)]Cl (PipeDTC = piperidine dithiocarbamate) and [Cu(ProOMeDTC)(2)] (ProOMeDTC = L-proline methyl ester dithiocarbamate)), have been loaded into the hydrophobic core of PF127 micelles and cancer-targeting counterparts. These nanoformulations have been studied for their dimensions (DLS, TEM) and stability, and tested for their cytotoxicity against aggressive human cancer cell lines. The in vitro results were paralleled with mechanistic studies through Confocal Laser Scanning Microscopy and xCELLigence analysis.

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 13925-03-6. COA of Formula: C7H10N2.

Organocatalytic asymmetric synthesis of highly substituted pyrrolidines bearing a stereogenic quaternary centre at the 3-position+

An organocatalytic asymmetric cascade reaction has been developed for the synthesis of highly substituted pyrrolidines having a stereogenic quaternary centre at the 3-position. N-Tosyl aminomethyl enone and trans–cyano-,-unsaturated ketone were utilized as the reaction partners in this method. Cinchonidine derived bifunctional amino-squaramide catalysts were the best to obtain the products in high enantio- and diastereoselectivities.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13925-03-6 is helpful to your research. Safety of 2-Ethyl-6-methylpyrazine.

New efficient design and synthesis of novel antioxidant and antifungal 7-imino[1,3]selenazolo[4,5-d]pyrimidine-5(4H)-thiones utilizing a base-promoted cascade addition/cyclization sequence

A straightforward strategy for the efficient synthesis of multi-functionalized 7-imino[1,3]selenazolo[4,5-d]pyrimidine-5(4H)-thiones bearing an incorporated N-phenylmethanethioamide fragment from the heteroannulation of several 2,4,5-trisubstituted 1,3-selenazoles with readily accessible phenyl isothiocyanates was established in boiling pyridine. To enrich the biological profile of the newly synthesized fused heterocyclic scaffold, some noted pharmacophores such as pyrrolidine, piperidine, morpholine, fluorine, and bromine were inserted into the framework. Inhibitory activities of the selenium-containing heterocycles were assessed against DPPH and Candida albicans. Antioxidant activities as IC50 values were observed in the range of 0.010-0.063 mM. Results revealed that 6-phenyl-substituted selenazolopyrimidines bearing C-2-pyrrolidine and C-2-piperidine both with IC50 value of 0.010 mM were superlative amongst others. Being far superior to ascorbic acid (IC50 = 0.022 mM), 4-fluorophenyl-substituted compounds bearing 2-morpholine residual (IC50 = 0.014 mM), and 2-piperidine (IC50 = 0.019 mM) were ranked in the second place and third place of antioxidant efficacy, respectively. Moreover, para-bromo and fluoro substituted N-phenylselenazolo[4,5-d]pyrimidines containing pyrrolidine moiety exhibited similar and six times higher potency for death and blocking of Candida albicans fungus than ketoconazole, respectively. Consequently, some of these selenazolopyrimidines are promising anti-Candida albicans as well as antioxidant lead compounds which can be used in the treatment of candidiasis, cancer, and neurodegenerative and diabetes diseases.

Synthesis and Evaluation of Novel Iminosugars Prepared from Natural Amino Acids

Cyclopropanated iminosugars have a locked conformation that may enhance the inhibitory activity and selectivity against different glycosidases. We show the synthesis of new cyclopropane-containing piperidines bearing five stereogenic centers from natural amino acids l-serine and l-alanine. Those prepared from the latter amino acid may mimic l-fucose, a natural-occurring monosaccharide involved in many molecular recognition events. Final compounds prepared from l-serine bear S configurations on the C5 position. The synthesis involved a stereoselective cyclopropanation reaction of an alpha,beta-unsaturated piperidone, which was prepared through a ring-closing metathesis. The final compounds were tested as possible inhibitors of different glycosidases. The results, although, in general, with low inhibition activity, showed selectivity, depending on the compound and enzyme, and in some cases, an unexpected activity enhancement was observed.

Benchmark Dose Modeling of In Vitro Genotoxicity Data: a Reanalysis

The methods of applied genetic toxicology are changing from qualitative hazard identification to quantitative risk assessment. Recently, quantitative analysis with point of departure (PoD) metrics and benchmark dose (BMD) modeling have been applied to in vitro genotoxicity data. Two software packages are commonly used for BMD analysis. In previous studies, we performed quantitative dose-response analysis by using the PROAST software to quantitatively evaluate the mutagenicity of four piperidine nitroxides with various substituent groups on the 4-position of the piperidine ring and six cigarette whole smoke solutions (WSSs) prepared by bubbling machine-generated whole smoke. In the present study, we reanalyzed the obtained genotoxicity data by using the EPA’s BMD software (BMDS) to evaluate the inter-platform quantitative agreement of the estimates of genotoxic potency. We calculated the BMDs for 10%, 50%, and 100% (i.e., a two-fold increase), and 200% increases over the concurrent vehicle controls to achieve better discrimination of the dose-responses, along with their BMDLs (the lower 95% confidence interval of the BMD) and BMDUs (the upper 95% confidence interval of the BMD). The BMD values and rankings estimated in this study by using the EPA’s BMDS were reasonably similar to those calculated in our previous studies by using PROAST. These results indicated that both software packages were suitable for dose-response analysis using the mouse lymphoma assay and that the BMD modeling results from these software packages produced comparable rank orders of the mutagenic potency.

Structure controlled solvatochromism and halochromic fluorescence switching of 2,2 ‘-bipyridine based donor-acceptor derivatives

Simple donor-acceptor derivatives were prepared by substituting alicyclic amines into the 2,2 ‘-bipyridine (Bpy) core unit and they exhibited a substituent structure dependent solution and solid state fluorescence, solvatochromism, and halochromic fluorescence switching in solution and solid state. Structural studies showed the formation ofs-transconformation with the internal cancellation of dipoles in solid state. However, the protonation of the pyridine unit produceds-cisconformation. Pyrrolidine (Bpy-Pyr) and piperidine (Bpy-Pip) substituted Bpy derivatives showed strong solid state fluorescence compared to other compounds. Substituent structure dependent reversible fluorescence switching was observed upon exposure to trifluoroacetic acid (TFA) and ammonia (NH3). Interestingly, theN-methyl piperazine (1MP) substituted compound (Bpy-1MP) showed comparatively strong fluorescence under acidic conditions compared to basic conditions. In contrast,Bpy-Pyrshowed strong fluorescence under basic conditions compared to acidic conditions. The absorption studies also revealed different changes with respect to pH for both compounds. The subtle structure-controlled fluorescence modulation with pH could be of potential interest for bio-imaging and optical devices.

Stereoselective synthesis of 3-spiropiperidino indolenines via S(N)2-type ring opening of activated aziridines with 1H-indoles/Pd-catalyzed spirocyclization with propargyl carbonates

3-Spiropiperidino indolenines have been synthesized via novel Lewis acid-catalyzed S(N)2-type ring opening of activated aziridines with 1H-indoles followed by Pd-catalyzed dearomative spirocyclization with propargyl carbonates in up to 88% yields. The step and pot-economic transformation comprises sequential C-C, C-N, and C-C bond forming steps generating two stereogenic centers including an all-carbon quaternary stereocenter to furnish the products in diastereomerically pure (dr >99:1) forms with excellent enantiomeric excess (ee up to >99%). The synthetic versatility of the strategy has been illustrated by converting the synthesized products into spirocyclic indolenine 2-piperidinones, dihydropiperidines, and 5-alkynylated piperidines.

Mechanistic and Performance Studies on the Ligand-Promoted Ullmann Amination Reaction

Over the last two decades many different auxiliary ligand systems have been utilized in the copper-catalyzed Ullmann amination reaction. However, there has been little consensus on the relative merits of the varied ligands and the exact role they might play in the catalytic process. Accordingly, in this work some of the most commonly employed auxiliary ligands have been evaluated for C-N coupling using reaction progress kinetic analysis (RPKA) methodology. The results reveal not only the relative kinetic competencies of the different auxiliary ligands but also their markedly different influences on catalyst degradation rates. For the model Ullmann reaction between piperidine and iodobenzene using the soluble organic base bis(tetra-n-butylphosphonium) malonate (TBPM) at room temperature, N-methylglycine was shown to give the best performance in terms of high catalytic rate of reaction and comparatively low catalyst deactivation rates. Further experimental and rate data indicate a common catalytic cycle for all auxiliary ligands studied, although additional off-cycle processes are observed for some of the ligands (notably phenanthroline). The ability of the auxiliary ligand, base (malonate dianion), and substrate (amine) to all act competitively as ligands for the copper center is also demonstrated. On the basis of these results an improved protocol for room-temperature copper-catalyzed C-N couplings is presented with 27 different examples reported.

Synthesis, crystal and solution structures of platinacyclic complexes containing eugenol, the main bioactive constituent of Ocimum sanctum L. oil

The dinuclear platinacyclic complex [Pt2Cl2(Eug-1H)(2)] (1) (Eug-1H = deprotonated eugenol) has been synthesized. Reaction of 1 with amines afforded [PtCl(Eug-1H)(pyridine)] (2), [PtCl(Eug-1H)(4-Me-pyridine)] (3), [PtCl(Eug-1H)(piperidine)] (4), [PtCl(Eug-1H)(quinoline)] (5), [PtCl(Eug-1H)(NH3)] (6), [PtCl(Eug-1H)(4-Me-aniline)] (7), [PtCl(Eug-1H)(4-Cl-aniline)] (8), [Pt(Eug-1H)(8-O-quinoline)] (9) and [Pt(Eug-1H)(8-O-2-Me-quinoline)] (10). X-ray diffraction and NMR analysis show that in complexes 1-10 the chelating eugenol ligand is bound with the Pt(II) ion both through the ethylenic double bond of the allyl group and at a benzene carbon atom; in 2-10 the donor N atom of the amine is in the cis-position with respect to the ethylenic double bond. For complexes 2 and 3, two types of relatively strong highly directional intermolecular interactions are observed in the crystal packing: O-H center dot center dot center dot ClPt(II) hydrogen bonds and C-H center dot center dot center dot pi interactions, in 3 further complemented by C-H center dot center dot center dot Cl interactions. The crystal packing of 7 is dominated by dimer formation through O-H center dot center dot center dot O, N-H center dot center dot center dot Cl, C-H center dot center dot center dot Cl and C-H center dot center dot center dot pi interactions. In a d-chloroform solution of 2-5 two types of strong intermolecular interactions were detected: a Cl3C-D center dot center dot center dot ClPt(II) hydrogen bond and Cl2DC-Cl center dot center dot center dot Pt(II) halogen bond. Complex 9 exhibits significant activities on the human cancer cells KB, Hep-G2, MCF-7 and Lu, with IC50 values of 8.7, 10.8, 9.9 and 10.4 mu M respectively. (C) 2018 Elsevier Ltd.

Design, synthesis and neuropharmacological evaluation of new 2,4-disubstituted-1,5-benzodiazepines as CNS active agents

Benzodiazepines (BZDs) represent a class of privilege scaffold in the modern era of medicinal chemistry as CNS active agents and BZD based drugs are used to treat different psychotic disorders. Inspired from the therapeutic potential of BZDs as promising CNS active agents, in the present work three different series of 1,5-benzodia-zepines bearing various substitutions at position 2 and 4 of the benzodiazepine core were synthesized by con-densing different substituted chalcones with o-phenylenediamine in the presence of piperidine as a base catalyst. Structural characterization of title compounds was done by using various analytical techniques such as IR, NMR, elemental analysis and mass spectral data. All the synthesized compounds (9a-d, 10a-e and 11a-c) were sub-jected to in vivo neuropharmacological studies to evaluate their CNS depressant and antiepileptic activity. Results of in vivo evaluation data showed that analogue 11b exhibited potent CNS depressant activity which was comparable to the standard drug diazepam. Compounds 10b and 10c displayed significant antiepileptic activity however they were less potent than the standard drug phenobarbitone. Molecular docking studies were per-formed using MOE software to find the interaction pattern and binding mode at the GABAA receptor (PDB Id: 6HUP). The results of the docking studies were in good agreement with the observed in vivo activity and revealed the satisfactory binding mode of the compounds within the binding site of the protein. The docking scores for the most promising candidates 10c, 11b and Diazepam were found to be -9.18, -9.46 and -9.88, respectively. Further, the compounds showed compliance with the Lipinski’s ‘rule of five’ and exhibited favourable drug -likeness scores. The identified leads can be explored further for the design and development of new BZD based psychotropic agents.
