Design and synthesis of substituted (1-(benzyl)-1H-1,2,3-triazol-4-yl)(piperazin-1-yl)methanone conjugates: study on their apoptosis inducing ability and tubulin polymerization inhibition

A library of substituted (1-(benzyl)-1H-1,2,3-triazol-4-yl)(piperazin-1-yl)methanone derivatives were designed, synthesized and screened for their in vitro cytotoxic activity against BT-474, HeLa, MCF-7, NCI-H460 and HaCaT cells by employing 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Among all the synthesized analogues, compound 10ec displayed the highest cytotoxicity with the IC50 value of 0.99 +/- 0.01 mu M towards BT-474 cancer cell line. The target compound (10ec) was also evaluated for its tubulin polymerization inhibition study. Detailed biological studies such as acridine orange/ethidium bromide (AO/EB), DAPI and annexin V-FITC/propidium iodide staining assay suggested that compound 10ec induced the apoptosis of BT-474 cells. The clonogenic assay revealed that the inhibition of colony formation in BT-474 cells by 10ec in concentration-dependent manner. Moreover, the flow cytometric analysis revealed that 10ec induced apoptosis via cell cycle arrest at the sub-G1 and G2/M phase. In silico studies of sulfonyl piperazine-integrated triazole conjugates unveil that they possess drug-like properties. According to the molecular modelling studies, compound 10ec binds to the colchicine binding site of the tubulin.

High-permeability and anti-fouling nanofiltration membranes decorated by asymmetric organic phosphate

Aiming at the two challenging bottlenecks of trade-off effect and membrane fouling that limit the development of nanofiltration (NF) membranes, this work developed a high-performance NF membrane based on the modification by an asymmetric hydrophilic zoledronic acid (ZA). ZA plays multiple roles: (1) the self-restrictive diffusion effect of piperazine (PIP)/ZA obtained from the reaction of PIP and ZA resulted in smooth membrane surface; (2) the imidazolyl on ZA uninvolved in interfacial polymerization (IP) led to enlarged polyamide network pores and provided more solvent tunnels; (3) all groups of ZA improved the membrane hydrophilicity; (4) the electronegative phosphate groups made a significant contribution to the strong membrane surface electronegativity. As a result, the ZA-modified membrane exhibited nearly five times higher permeability than that of traditional NF membranes, accompanied by perfect selectivity of SO42- and Cl- as well as the outstanding anti-fouling property, indicating its enormous application prospect in water treatment.

Novelpiperazine-tailoredursolic acid hybrids as significant antibacterial agents targeting phytopathogensXanthomonas oryzaepv.oryzaeandX. axonopodispv.citriprobably directed by activation of apoptosis

BACKGROUND Induced apoptosis is an effective technique that can reprogram cellular physiological and pathological processes to eradicate undesirable cells using their innate systems. Inspired by this, numerous apoptosis inducers have been developed to treat animal diseases, especially in the anticancer field. However, few studies have reported on the development of inductive agents that attack plant pathogens by activation of apoptosis. With the aim of exploring and discovering apoptosis inducers that target phytopathogens, a cluster of piperazine-tailored ursolic acid (UA) hybrids was systematically fabricated. RESULTS In vitrotesting showed that the title molecules could inhibit the growth of two intractable bacterial strains, defined asXanthomonas oryzaepv.oryzaeandX. axonopodispv.citri. The corresponding lowest EC(50)values were 0.37 and 1.08 mu g mL(-1), which exceed those of UA (>400 mu g mL(-1)) and positive controls. Moreover, compounds5uand5vcould manage bacterial blightin vivousing pot experiments. Flow cytometer analysis indicted that the title compounds could induce distinct apoptotic behaviors on tested bacteria. In-depth study revealed that the introduction of designed compounds could reduce the enzyme activities of catalase and superoxide dismutase, subsequently leading to the accumulation of reactive oxygen species. CONCLUSION This study promoted the development of apoptosis initiators for managing bacterial infections in agriculture by an innovative mode of action. (c) 2020 Society of Chemical Industry

Newly Synthesized Fluorinated Cinnamylpiperazines Possessing Low In Vitro MAO-B Binding

Herein, we report on the synthesis and pharmacological evaluation of ten novel fluorinated cinnamylpiperazines as potential monoamine oxidase B (MAO-B) ligands. The designed derivatives consist of either cinnamyl or 2-fluorocinnamyl moieties connected to 2-fluoropyridylpiperazines. The three-step synthesis starting from commercially available piperazine afforded the final products in overall yields between 9% and 29%. An in vitro competitive binding assay using l-[H-3]Deprenyl as radioligand was developed and the MAO-B binding affinities of the synthesized derivatives were assessed. Docking studies revealed that the compounds 8-17 were stabilized in both MAO-B entrance and substrate cavities, thus resembling the binding pose of l-Deprenyl. Although our results revealed that the novel fluorinated cinnamylpiperazines 8-17 do not possess sufficient MAO-B binding affinity to be eligible as positron emission tomography (PET) agents, the herein developed binding assay and the insights gained within our docking studies will certainly pave the way for further development of MAO-B ligands.

5-HT1A targeting PARCEST agent DO3AM-MPP with potential for receptor imaging: Synthesis, physico-chemical and MR studies

Contrast enhancement in MRI using magnetization or saturation transfer techniques promises better sensitivity, and faster acquisition compared to T-1 or T-2 contrast. This work reports the synthesis and evaluation of 5-HT1A targeted PARACEST MRI contrast agent using 1,4,7,10-tetraazacycloDOdecane-4,7,10-triacetAMide (DO3AM) as the bifunctional chelator, and 5-HT1A-antagonist methoxyphenyl piperazine (MPP) as a targeting unit. The multistep synthesis led to the MPP conjugated DO3AM with 60% yield. CEST-related physicochemical parameters were evaluated after loading DO3AM-MPP with paramagnetic MRI active lanthanides: Gadolinium (Gd-DO3AM-MPP) and Europium (Eu-DO3AM-MPP). Luminescence lifetime measurements with Eu-DO3AM-MPP and computational DFT studies using Gd-DO3AM-MPP revealed the coordination of one water molecule (q = 1.43) with metal-water distance (r(M)-H2O) of 2.7 angstrom and water residence time (tau(m)) of 0.23 ms. The dissociation constant of K-d 62 +/- 0.02 pM as evaluated from fluorescence quenching of 5-HT1A (protein) and docking score of -4.81 in theoretical evaluation reflect the binding potential of the complex Gd-DO3AM-MPP with the receptor 5-HT1A. Insights of the docked pose reflect the importance of NH2 (amide) and aromatic ring in Gd-DO3AM-MPP while interacting with Ser 374 and Phe 370 in the antagonist binding pocket of 5-HT1A. Gd-DO3AM-MPP shows longitudinal relaxivity 5.85 mM(-1)s(-1) with a water residence lifetime of 0.93 ms in hippocampal homogenate containing 5-HT1A. The potentiometric titration of DO3AM-MPP showed strong selectivity for Gd3+ over physiological metal ions such as Zn2+ and Cu2+. The in vitro and in vivo studies confirmed the minimal cytotoxicity and presential binding of Gd-DO3AM-MPP with 5-HT1A receptor in the hippocampus region of the mice. Summarizing, the complex Gd-DO3AM-MPP can have a potential for CEST imaging of 5-HT1A receptors.

Structural elucidation of Levofloxacin and Ciprofloxacin using density functional theory and Raman spectroscopy with inexpensive lab-built setup

In the present work, we have investigated the structures of fluoroquinolones Levofloxacin and Ciprofloxacin using Raman spectroscopy and density functional theory calculations. The Raman spectra of Levofloxacin and Ciprofloxacin were recorded with lab-built inexpensive Raman spectroscopy setup that uses 638 nm laser diode. Raman spectra in the fingerprint spectral region (900-1800 cm(-1)) were investigated for both the molecules. The density functional theory (DFT) utilizing B3LYP functional with 6-31+G(d,p) basis set was used to investigate the minimum energy structures of two molecules along with the calculation of Raman spectrum. Molecular complexes of Levofloxacin and Ciprofloxacin with one and two water molecules were also studied to see the effect of H-bonding on Raman spectra. It was found that the conformation and orientation of piperazine ring along with the orientation of hydroxyl group plays a vital role in determination of the minimum energy structure. The calculated Raman spectra of bare molecules and their complexes with water molecules were compared to the experimental Raman spectra. The calculated Raman spectrum of minimum energy structure was found to be in good agreement with the experimental spectrum. Further it was observed that the experimental Raman spectrum is better explained when H-bonding is considered, which could be due to the water molecule or the dimer formation of the molecules under investigation.

Bioreducible cationic random copolymer for gene delivery

Cationic polymers have been widely investigated for gene delivery, although their low transfection efficiency and high cytotoxicity limit their application. We synthesized a bioreducible cationic random copolymer, poly(cystamine bisacylamide-aminoethyl piperazine)-co-poly(cystamine bisacylamide-histamine) (denoted as CBA-AEP-His) fromN,N ‘-cystamine bis acrylamide (CBA) with aminoethyl piperazine (AEP) and histamine (His). CBA-AEP-His copolymer possesses disulfide linkages that endow it with redox-responsivity to the intracellular environment. This polymer efficiently condenses pZNF580 into complexes with the size of 160 +/- 4 nm to 280 +/- 5 nm and positive zeta potential of 20 +/- 0.3 mV to 30 +/- 0.4 mV. The gel-retardation assay shows that CBA-AEP-His can retard pZNF580 even at a low mass ratio of 1/1. The gene complexes were triggered to release pZNF580 when exposed to the reducing environment of dithiothreitol (DTT). CBA-AEP-His random copolymer presented higher buffer capacity owing to its His moieties, which protected pZNF580 from DNase degradation. The gene transfection results reveal that CBA-AEP-His can efficiently deliver pZNF580 and transfect EA. Hy926 cells. The MTT assay indicates that CBA-AEP-His and its complexes exhibit lower cytotoxicity than PEI25KDa. These results illustrate that CBA-AEP-His had promising properties for gene delivery, which may provide a suitable platform for the development of a non-viral gene carrier.

Graphene oxide interlayered thin-film nanocomposite hollow fiber nanofiltration membranes with enhanced aqueous electrolyte separation performance

In this study, a kind of thin-film nanocomposite (TFN) hollow fiber nanofiltration (NF) membranes was fabricated via incorporating graphene oxide (GO) interlayer using the interfacial polymerization (IP) reaction between piperazine (PIP) and trimesoyl chloride (TMC). The surface morphology and cross-sectional structure of the fabricated TFN hollow fiber NF membrane were extensively investigated. The effects of the PIP concentration, species of the aqueous additives, and the GO loading on the structure and performance of the hollow fiber NF membrane were also investigated in detail and the optimal preparation conditions were achieved. Fourier transform infrared spectroscopy (FTIR) confirmed the successful introduction of the GO interlayer into the composite hollow fiber NF membrane. Moreover, the incorporation of GO interlayer helped to reduce the skin thickness of the composite hollow fiber NF membrane remarkably, and thus helped to increase greatly the water permeance while maintaining a high salt rejection. Under an optimal GO loading of 20.0 mg m(-2), the TFN hollow fiber NF membrane achieved a water permeance of 80 L m(-2) h(-1) MPa-1 and a Na2SO4 rejection of 96.1% for 2000 mg L-1 aqueous Na2SO4 solution, much higher than the interlayer-free thin-film composite (TFC) membrane. Meanwhile, the TFN hollow fiber NF membrane showed an excellent selectivity of Na2SO4 over NaCl, as well as good fouling resistance and long-term stability, demonstrating the vast potential in application for the selective separation of monovalent salt and divalent salt.

High-performance nanofiltration membrane with structurally controlled PES substrate containing electrically aligned CNTs

A structurally controlled polyethersulfone (PES) membrane, as the substrate of the thin film composite nanofiltration (NF) membranes, was designed and fabricated with aligned carbon nanotubes (ACNTs) by a direct current electric field. The morphology and properties of the NF membranes were simultaneously affected by the PES substrate with especial macrovoids and ACNTs, increasing the permeability from 6.4 to 29.7 L/m(2) h bar. It was confirmed by FT-IR and XPS that the poly(piperazine amide) selective layer of the modified NF membrane has an increased content of -COOH for enhanced hydrophilicity. The zeta potential proves that the surface of the NF membrane modified by electric field has weaker negative charge than that of unmodified membrane in the range of pH = 5-9. Under the combined action of the Donnan effect and size exclusion, the rejection of MgCl2 increased while maintaining the dianion rejection above 95%. Particularly, the NF membrane modified with ACNTs exhibited better chlorine resistance and antifouling ability, thus improving the stability and perdurability of membranes. Our work utilizes the characteristics of ACNTs to explore its potential in NF membranes.
