Prolonged bioluminescence imaging in living cells and mice using novel pro-substrates for Renilla luciferase

The prodrug or caged-luciferin strategy affords an excellent platform for persistent bioluminescence imaging. In the current work, we designed and synthesized ten novel pro-substrates for Renilla luciferase by introducing ester protecting groups of different sizes into the carbonyl group of the free luciferin 1. Taking advantage of intracellular esterases, lipases, and nucleophilic substances, the ester protecting groups were hydrolyzed, resulting in the release of a free luciferin and a bioluminescence signal turn-on. Among the tested pro-substrates, the butyryloxymethyl luciferin 7 exhibited low cytotoxicity and a prolonged luminescence signal both in cellulo and in vivo. Therefore, the butyryloxymethyl luciferin 7 can act as a promising substrate for noninvasive extended imaging in diagnostic and therapeutic fields.

Six Years (2012-2018) of Researches on Catalytic EZH2 Inhibitors: The Boom of the 2-Pyridone Compounds

Enhancer of zeste homolog 2 (EZH2), the catalytic subunit of the Polycomb repressive complex 2 (PRC2), catalyzes the methylation of lysine 27 of histone H3 (H3K27) up to its trimethylated form (H3K27me), inducing by this way block of transcription and gene silencing. High levels of H3K27me3 have been found in both hematological malignancies and solid cancers, due to EZH2 overexpression and/or EZH2 mutation. From 2012, a number of highly potent and selective catalytic inhibitors of EZH2 have been reported, almost all bearing a 2-pyridone group in their structure. Typically, 2-pyridone inhibitors are selective for EZH2 over other methyltransferases, and some of them are specific for EZH2 over EZH1, others behave as dual EZH2/EZH1 inhibitors. The 2-pyridone moiety was crucial for the enzyme inhibition, as revealed later by crystallographic studies because it occupies partially the site for the co-substrate SAM (or the by-product, SAH) in the binding pocket of the enzyme, accounting for the SAM-competitive mechanism of action displayed by all the 2-pyridone inhibitors. The 2-pyridone warhead is linked to a support substructure, that can be either a bicyclic heteroaromatic ring (such as indazole, see for instance EPZ005687 and UNC1999, or indole, see for instance GSK126, EI1, and the more recent CPI-1205) or a simple monocyclic (hetero) aromatic ring (tazemetostat, MC3629, (R)-OR-S1/2), eventually annulated with the amide chain carrying the 2-pyridone group (3,4-dihydroisoquinoline-1(2H)-ones). Different substitutions at the support moiety influence the pharmacokinetics and pharmacodynamics of the compounds as well as their water solubility. In cancer diseases, the first reported 2-pyridone inhibitors displayed high antiproliferative effects in vitro and in vivo in lymphomas characterized by mutant EZH2 (such as Y641N), but the most recent compounds exert their anticancer activity against tumors with wild-type EZH2 as well. The dual EZH2/1 inhibitors have been recently reported to be more effective than EZH2 selective inhibitors in specific leukemias including leukemias cancer stem cells.

In silico studies on CNR1 receptor and effective cyanobacterial drugs: Homology modelling, molecular docking and molecular dynamic simulations

Cannabinoid receptor 1(CNR1) is strongly related with A G-protein coupled receptors that have been found to exist in the organ systems of human beings. It has an important role to play as therapeutic targets in certain challenging diseases globally (cancer, diabetes, obesity, cardiac dysfunction, CNS disorders, inflammation and pain). This computational study was carried out in Schrodinger suite packages like prime application, sitemap generation, grid and glide SP that are available in version 10.2 Maestro. The target CNR1 was retrieved from UniProt, and cyanobacterial bioactive compounds (ligands) were obtained from chemical database. Homology modelling acts as an effective tool for docking studies in these proteins. As a result, homology modelled target exhibited low sequence similarity and thus the molecule was made as the quality target. The bioactive molecules such as Symplocamide A, Pompanopeptine B, Lyngbyastatin 5, Lyngbyabellin D, Hoiamide A, Nostocylopeptide A3, Lyngbyabellin H, and Cryptophycin 327 are chosen from various cyanobacterial species based on their biological and pharmacological activities. Among the eight cyanobacterial molecules, Symplocamide A had a potent docking score and revealed good binding affinities than other ligands. According to the results we suggest that Symplocamide A could be developed as a potential drug molecule for CNR1 targets.

Size-selective catalysts in five functionalized porous coordination polymers with unsaturated zinc centers

The five reported structural isomorphic porous coordination polymers (PCPs) 1-5, namely, [Zn(L)(ip) (1), Zn(L)(aip) (2), Zn(L)(hip) (3), Zn(L)(nip) (4), and Zn(L)(HBTC) (5) (L = N-4, N-4′-di(pyridine-4-yl)biphenyl-4,4′-dicarboxamide, H(2)ip = isophthalic acid, H(2)aip = 5-aminoisophthalic acid, H(2)hip = 5-hydroxyisophthalic acid, H(2)nip = 5-nitroisophthalic acid, H3BTC = 1,3,5-benzenetricarboxylic acid)] were used to catalyze the acetylation of phenol. All these heterogeneous catalysts exhibit good catalytic efficiency and size-selectivity toward the acetylation of phenols owing to their unsaturated metal centers, non-coordinated amide, and suitable channel size and shape. Among them, 2 displays the highest catalytic activity and excellent cooperative catalysis due to the presence of basic non-coordinated amide groups.

New 2,9-disubstituted-1,10-phenanthroline derivatives with anticancer activity by selective targeting of telomeric G-quadruplex DNA

Fifteen new 1,10-phenanthrolines disubstituted at positions 2 and 9 via amide bonds with different heterocycles have been designed and synthesized as G-quadruplex DNA stabilizers. Ten compounds were evaluated for the in vitro anticancer activity against 60 human tumor cell lines panel, four of them showing a very good inhibitory activity on several cell lines. To assess the ability of the most active compounds to interact with G-quadruplex DNA (G4-DNA), circular dichroism experiments were performed. The potency of the compounds to stabilize the G4-DNA has been shown from the thermal denaturation experiments. The mechanism of compounds binding to DNA and to G4-DNA was theoretically investigated by molecular docking studies. The experimental results demonstrated excellent capacity of the two compounds bearing two pyridin-3-yl residues (methylated and non-methylated) to act as selective G-quadruplex binders with promising anticancer activity.

Biosorption isotherm study of Cd2+ Pb2+ and Zn2+ biosorption onto marine bacterium Pseudoalteromonas sp SCSE709-6 in multiple systems

To overcome the low efficiency and prerequisites conditions of simultaneous metals removal and the unsuitability of single metal adsorption isotherm models in multiple metals, the multiple biosorption of Cd2+, Pb2+ and Zn2+ onto a new marine Pseudoalteromonas sp. SCSE709-6 from aqueous solution was studied and compared with single metal system. Results showed that Pseudoalteromonas sp. SCSE709-6 was a competitive biosorbent for metals from aqueous solutions in single system (maximum adsorption capacity: 138 mmol g(-1) for Cd2+, 1.05 mmol g(-1) for Pb2+ and 0.91 mmol g(-1) for Zn2+, respectively). The affinity between metals and biosorbent calculated by the separation factor in binary metals systems followed the order: Pb2+ > Cd2+ > Zn2+. In multiple metals systems, Cd2+ biosorption was the most sensitive, while Pb2+ biosorption was the least sensitive. In addition, Pb2+ biosorption had less pH dependence than the biosorption of Cd2+ and Zn-2. Among six isotherm models applied in this study, the extended Freundlich isotherm model best described the binary metal biosorption behaviors. Isotherm analysis revealed that binary biosorption was a complex process which occurred both mono- and multi-layer biosorption. FT-IR result spectrum revealed that carboxyl, amide, acyl and hydroxyl played a significant role in metals biosorption. This study showed superior performance of metal removal by Pseudoalteromonas sp. SCSE709-6 in multiple metals systems. (C) 2017 Elsevier B.V. All rights reserved.

Supported optically active poly(amide-imide) on magnetic graphene oxide/Fe3O4 for Hg2+ adsorption from aqueous solution

The ternary superparamagnetic nanocomposites consisting of graphene oxide (GO), Fe3O4 nanoparticles, and optically active poly(amide-imide) (PAI) were fabricated in three steps consisting of a facile one-pot in situ growth of Fe3O4 on GO, resulted in the preparation of the magnetic Fe3O4@GO, modification of Fe3O4@GO by 3-aminopropyltriethoxy silane to introduce amino groups on its surface, and subsequently its compositing by various levels of 5, 10, and 15 wt% with chiral PAI derived from 3,5-diamino-N-(4-(di(1H-indol-3-yl)methyl)phenyl)benzamide and N,N ‘-(4,4 ‘-carbonyldiphthaloyl)-bis-l-phenylalanine diacid through ultrasonic irradiation. Characterization of the resulting nanocomposites was performed by Fourier transform infrared spectroscopy, X-ray diffraction, vibrating sample magnetometer, scanning electron microscope (SEM), and thermogravimetric analysis (TGA). The SEM analysis showed Fe3O4 nanoparticles with 30 nm size successfully decorated the GO nanosheets. The TGA analysis established the expected thermal stabilities for PAI/Fe3O4@GO nanocomposites. Furthermore, incorporation of Fe3O4@GO in polymer matrix improved the mechanical properties substantially. PAI/Fe3O4@GO 10 wt% was used to evaluate the sorption properties of Hg2+ at pH 7.
