Synthesis, spectroscopic characterization, DFT studies and biological activity of bis (1-(ethyl) piperidine) diselenide (L) and its complexes with selected group 12 metal halides

Se-2(2) (generated insitu by NaBH4 reduction of Se) on reaction with 1-(2-chloroethyl) piperidine hydrochloride under N-2 atmosphere resulted in bis(1-(ethyl) piperidine) diselenide (L) as an orange solid. It’s bimetallic complexes having the formula [Zn2Cl4L] (1), [Cd2Cl4L] (2) and [Cd2Br4L] (3) were also synthesized. L and its complexes 1-3 were characterized on the basis of physico-chemical and spectral (FT-IR, Mass, H-1, C-13, DEPT and Se-77 NMR) studies. IR spectroscopy revealed that M (II) ions (zinc and cadmium) are coordinated through selenium and nitrogen forming a five membered ring around M (II) ions. Elemental analysis measurement along with H-1, C-13, DEPT and ESI mass data confirmed the tetradentate mode of coordination of the ligand L. Moreover the coordination from selenium atom is also supported by the downfield shift of signal in Se-77 NMR spectroscopy. Powder XRD diffraction pattern reveals the crystalline nature of Ligand L and complexes 1-3. Heteroditopic ligand L (N, Se, Se, N) ligates through both selenium and nitrogen atoms to two respective metal halides in complexes 1-3, thus forming bimetallic complexes. Using DFT-based optimization of structures, the HOMO-LUMO energy gaps and molecular electrostatic potential surface of ligand L and complexes 1-3 were theoretically calculated at the B3LYP/LANL2DZ level of theory. These complexes adopt distorted tetrahedral geometry around M(II) ions as revealed by bond angles. HOMO-LUMO energy gap was calculated which allowed the calculation of relative properties like chemical hardness, chemical inertness, chemical potential, nucleophilicity and electrophilicity index of the synthesized products. The experimentally obtained IR and NMR results showed a good correlation with those of the theoretical ones. Ligand L and complex 1-3 displayed significant antibacterial and antifungal activity.

Synthesis and Investigation of Tetrahydro-beta-carboline Derivatives as Inhibitors of Plant Pathogenic Fungi

A series of tetrahydro-ss-carbolines substituted with an alkyl or acyl side chain was synthesized and screened for its antifungal activity against plant pathogenic fungi (Bipolaris oryzae, Curvularia lunata, Fusarium semitectum, and Fusarium fujikuroi). The structure activity relationship revealed that the substituent at the piperidine nitrogen plays an important role for increasing antifungal activities. In this series, 2-octyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole (3g) displayed potent antifungal activities with a minimum inhibitory concentration of 0.1 mu g/mL, including good inhibitory activity to the radial growth of fungus at a concentration of 100 mu g/mL compared to amphotericin B.

Structural diversity in copper(I) iodide complexes with 6-thioxopiperidin-2-one, piperidine-2,6-dithione and isoindoline-1,3-dithione ligands

Copper(I) iodide complexes are well known for displaying a diverse array of structural features even when only small changes in ligand design are made. This structural diversity is well displayed by five copper(I) iodide compounds reported here with closely related piperidine-2,6-dithione (SNS), isoindoline-1,3-dithione (SNS6), and 6-thioxopiperidin-2-one (SNO) ligands: di-mu-iodido-bis[(acetonitrile-kappa N)(6-sulfanylidenepiperidin-2-one-kappa S)copper(I)], [Cu2I2(CH3CN)(2)(C5H7NOS)(2)] (I), bis(acetonitrile-kappa N)tetra-mu(3)-iodido-bis(6-sulfanylidenepiperidin-2-one-kappa S)-tetrahedro-tetracopper(I), [Cu4I4(CH3CN)(4)-(C5H7NOS)(4)] (II), catena-poly[[(mu-6-sulfanylidenepiperidin-2-one-kappa O-2: S)copper(I)]-mu(3)-iodido], [CuI(C5H7NOS)](n) (III), poly[[(piperidine-2,6-dithione-kappa S)copper(I)]-mu(3)-iodido], [CuI(C5H7NS2)](n) (IV), and poly[[(mu-isoindoline-1,3-dithione-kappa S-2:S)copper(I)]-mu(3)-iodido], [CuI(C8H5NS2)](n) (V). Compounds I and II crystallize as discrete dimeric and tetrameric complexes, whereas III, IV, and V crystallize as polymeric two-dimensional sheets. To the best of our knowledge, compound III is the first instance of an extended hexagonal [Cu3I3] structure that is not supported by bridging ligands. Structures I, II, and IV display weak to moderately strong Cu center dot center dot center dot Cu cuprophilic interactions [Cu center dot center dot center dot Cu internuclear distances range between 2.5803 (10) and 2.8485 (14) angstrom]. All structures except III display weak hydrogen-bonding interactions between the N-H of the ligand and the mu(2) and mu(3)-I- atoms. Structure III contains classical N-H center dot center dot center dot O interactions between the SNO ligands that connect the molecules in a three-dimensional framework. Complex V features pi-pi stacking interactions between the aryl rings of the SNS6 ligands within the same polymeric sheet. In structure IV, there were three partially occupied solvent molecules of dichloromethane and one partially occupied molecule of acetonitrile present in the asymmetric unit. The SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9-18] was used to correct the diffraction data for diffuse scattering effects and to identify the solvent molecules. The given chemical formula and other crystal data do not take into account the solvent molecules.

Racemic mefloquinium chlorodifluoroacetate: crystal structure and Hirshfeld surface analysis

In the racemic title molecular salt, C17H17F6N2O+center dot C2ClF2O3-(systematic name: 2-{[2,8-bis(trifluoromethyl) quinolin-4-yl](hydroxy) methyl} piperidin-1-ium chlorodifluoroacetate), the cation, which is protonated at the piperidine N atom, has the shape of the letter, L, with the piperidin-1-ium group being approximately orthogonal to the quinolinyl residue [the C-q-C-m-C-m-N-a (q = quinolinyl; m = methine; a = ammonium) torsion angle is 177.79 (18)degrees]. An intramolecular, charge-assisted ammonium-N-H center dot center dot center dot O(hydroxyl) hydrogen bond ensures the hydroxy-O and ammonium-N atoms lie to the same side of the molecule [O-h-C-m-C-m-N-a (h = hydroxyl) = -59.7 (2)degrees]. In the crystal, charge-assisted hydroxyl-O-H center dot center dot center dot O- (carboxylate) and ammonium-N+-H center dot center dot center dot O-(carboxylate) hydrogen bonds generate a supramolecular chain along [010]; the chain is consolidated by C-H center dot center dot center dot O interactions. Links between chains to form supramolecular layers are of the type C-Cl center dot center dot center dot pi (quinolinyl-C-6) and the layers thus formed stack along the a-axis direction without directional interactions between them. The analysis of the calculated Hirshfeld surface points to the dominance of F center dot center dot center dot H contacts to the surface (40.8%) with significant contributions from F center dot center dot center dot F (10.5%) and C center dot center dot center dot F (7.0%) contacts.

Anodic benzylic C(sp(3))-H amination: unified access to pyrrolidines and piperidines

An electrochemical aliphatic C-H amination strategy was developed to access the important heterocyclic motifs of pyrrolidines and piperidines within a uniform reaction protocol. The mechanism of this unprecedented C-H amination strategy involves anodic C-H activation to generate a benzylic cation, which is efficiently trapped by a nitrogen nucleophile. The applicability of the process is demonstrated for 40 examples comprising both 5- and 6-membered ring formations.

Synthesis and Cytotoxic Evaluation of Kojic Acid Derivatives with Inhibitory Activity on Melanogenesis in Human Melanoma Cells

Background: Malignant melanoma is an agressive tumour related to the overproduction of melanin, which provides colors of skin, eyes and hair. In addition contributing to the risk of malignant melanoma, abnormal production of melanin has many drawbacks, including hyperpigmentation, post-inflammatory pigmentation, melasma and skin aging. Kojic acid is currently employed in order to lighten skin pigmentation and provide depigmentation. Objective: Mannich bases of kojic acid with the structure of 2-substituted-3-hydroxy-6-hyroxymethyl/chloromethyl/methyl/morpholinomethyl/piperidinylmethylipyrrolidinylmethyl-4H-pyran-4-one (compounds 1-23) were synthesized by the reaction of kojic acid/chlorokojic acid/allomaltol and substituted benzylpiperazine derivatives in the presence of formaline. To obtain the cyclic amine (morpholine, piperidine and pyrrolidine) derivatives, nucleophilic substitutions were carried out. Method: Cytotoxic effects on A375 human malignant melanoma, IIGF-1 human gingival fibroblasts, and MRC-5 human lung cell lines were investigated by sulphorhodamine B assay. Control agents were vemurafenib, dacarbazine, temozolomide, and lenalidomide, which are the commercially available drugs for the treatment of malignant melanoma. Results: Cytotoxic action against melanoma cells was significantly more efficacious (IC50 : 11.26-68.58 mu M) than the FDA-approved drugs except for vemurafenib. Fourteen of the compounds were proven to have higher IC50 values for the non-cancerous cell lines, HGF-1, and MRC-5 cells. Melanogenesis inhibition assay was performed to observe the ability of the drugs to inhibit melanin production and certain compounds were shown to be capable of actively inhibiting melanin production in melanoma cells. Conclusion: Mannich bases of kojic acid derivatives may be promising therapeutic agents, since some have more potent erects on melanoma cells than previously FDA-approved drugs for the treatment of malignant melanoma.

Assessing the effects of cellulose-inorganic nanofillers on thermo/pH-dual responsive hydrogels

The incorporation of renewable bio-based materials/eco-friendly inorganic nanofillers into stimuli-responsive hydrogels meets the need for biocompatible and non-toxic functional materials. However, it remains challenging to build a three-dimensional network with enhanced mechanical properties and desired stimuli-responsive performances. In this study, dual stimuli-responsive hydrogels with interpenetrating polymer network structure are fabricated by the crosslinking of N-isopropylacrylamide (NIPAM)(1) and sodium alginate (SA)(2). 2,2,6,6-tetramethyl-piperidine-1-oxyl-oxidized cellulose nanofibers (TOCNF)(3) derived from energycane bagasse serves as a carrier material for nanosilicas (NS)(4) and nanoclays (NC)(5) and the effects of TOCNF, TOCNF/NS and TOCNF/NC on the hydrogels are thoroughly explored. Among these hydrogels, PNIPAM/SA-TOCNF-NS possesses the largest compressive strength of 66.7 kPa and it is 5.65 times higher than that of PNIPAM/SA. The thermo-sensitivity and pH-sensitivity of hydrogels are evidenced by swelling behaviors, optical properties, contact angle measurements and fluorescence tests. PNIPAM/SA-TOCNF exhibits the largest contact angle and the swelling processes for all the hydrogels are well fitted by pseudo-second-order swelling kinetic model. In addition, after incorporating carbon quantum dots, all the hydrogels display temperature dependent on-off fluorescence properties and this process are fully reversible with the heating and cooling cycles. These novel hydrogels with pH and temperature responsive characteristics and remarkable mechanical properties will open the door for interesting applications in smart sensors etc.

MWW-Type Titanosilicate Synthesized by Simply Treating ERB-P Zeolite with Acidic H2T6 and Its Catalytic Performance in a Liquid Epoxidation of 1-Hexene with H2O

Synthesis of a Ti-incorporated zeolite using a simple and economical method has recently become a focus of attention. The direct hydrothermal synthesis of Ti-MWW is most commonly applied; however, it is challenging to perform and exhibits low titanium utilization. An innovative strategy of synthesizing Ti-MWW is proposed in the present study by simply treating the ERB-1 precursor of an MWW-type boron silicate with a H2TiF6/HNO3 solution. This significantly shortens the Ti grafting process from 5 days to only a few hours and reduces the use of the structure-directing agent hexamethyleneimine (HMI); furthermore, no extraframework Ti is observed in the precursor, indicating good atomic economy. Typically, a piperidine (PI)-treated sample Ti-MWW2-1-PI exhibits a higher conversion (76.6%) than the original Ti-MWW (44.8%) in the epoxidation of 1-hexene. X-ray diffraction (XRD), inductively coupled plasma (ICP), and transmission electron microscopy (TEM) techniques are used to explain in detail the probable mechanism underlying the incorporation of Ti species into the MWW framework. X-ray photoelectron spectroscopy (XPS) is employed to study the coordinate state of the Ti and F species in the samples after treatment with a piperidine solution. This method can be applied to synthesize other kinds of lamellar-structured zeolites with heteroatoms.
