    ABSTRACT: By switching position of the N and S atom in the thiazole ring which were similar to the previously reported agent 5-(4-ethoxyphenyl)-4-(3',4',5'-trimethoxyphenyl)thiazol-2-amine, a series of 4,5-diarylthiazole derivatives were synthesized using Friedel-Crafts reaction based on chemical modification of Combrestatatin A-4 (CA-4). Their antiproliferative activities were evaluated and identified as new microtubule destabilizing agents. Structure-activity relationship study indicated that compound 8a with 3,4,5-trimethoxyphenyl group at the C-4 position and 4-ethoxyphenyl group at the C-5 position of 2-amino substituted thiazole was of the most potent inhibitory activity in this series. 8a was found to exhibit the IC50 values of 8.4-26.4nM in five human cancer cell lines, with comparable inhibition effects to CA-4. Moreover, 8a showed potency as a tubulin polymerization inhibitor, with colchicine site binding ability and comparable extent of inhibition against the growth of P-glycoprotein over-expressing multidrug resistant cell lines. Mechanism studies revealed that 8a could block the progression of cell cycle in the G2/M phase and result in cellular apoptosis in cancer cells. As a new tubulin destabilizing agent, 8a was also found high antivascular activity as it concentration-dependently reduced the cell migration and disrupted capillary like tube formation of HUVEC cells. Furthermore, 8a significantly suppressed the tumor growth in HCT116 and SK-OV-3 xenograft models with tumor growth inhibitory rate of 55.12% and 72.7%, respectively. Our studies highlighted that 8a was a promising microtubule targeting antitumor agent. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: A series of 1-arylpyrrolo[1,2-a]pyrazine-3-carboxamides were designed and synthesized as 18kDa translocator protein (TSPO) ligands. Anxiolytic-like activity of compounds was evaluated in the open field test and elevated plus maze test. Compounds 1a and 1b demonstrated high anxiolytic-like effect in the dose range of 0.1-1.0mg/kg comparable with that of diazepam. The involvement of TSPO receptor in the mechanism of anxiolytic-like activity of new compounds was proved by antagonism of the most active compound 1a with TSPO selective inhibitor PK11195. In vitro binding studies demonstrated high TSPO affinities for compounds 1a and 1b. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: In the course of our search for anti-dormant Mycobacterial substances, nybomycin (1) was re-discovered from the culture broth of a marine-derived Streptomyces sp. on the bioassay-guided separation. Compound 1 showed anti-microbial activity against Mycobacterium smegmatis and Mycobacterium bovis BCG with the MIC of 1.0μg/mL under both actively growing aerobic conditions and dormancy inducing hypoxic conditions. Compound 1 is also effective to Mycobacterium tuberculosis including the clinically isolated strains. The mechanistic analysis indicated that 1 bound to DNA and induces a unique morphological change to mycobacterial bacilli leading the bacterial cell death. Copyright © 2015 Elsevier Ltd.

    ABSTRACT: ABCC2 is a transporter with key influence on liver and kidney pharmacokinetics. In order to explore the structure-activity relationships of compounds that modulate ABCC2, and by doing so gain insights into drug-drug interactions, we screened a library of 432 compounds for modulators of radiolabeled β-estradiol 17-(β-d-glucuronide) (EG) and fluorescent 5(6)-carboxy-2',7'-dichlorofluorescein transport (CDCF) in membrane vesicles. Following the primary screen at 80μM, dose-response curves were used to investigate in detail 86 compounds, identifying 16 low μM inhibitors and providing data about the structure-activity relationships in four series containing 19, 24, 10, and eight analogues. Measurements with the CDCF probe were consistently more robust than for the EG probe. Only one compound was clearly probe-selective with a 50-fold difference in the IC50s obtained by the two assays. We built 24 classification models using the SVM and fused-XY Kohonen methods, revealing molecular descriptors related to number of rings, solubility and lipophilicity as important to distinguish inhibitors from inactive compounds. This study is to the best of our knowledge the first to provide details about structure-activity relationships in ABCC2 modulation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: Two novel series of tris-cationic, tripled-headed, double-tailed amphiphiles were synthesized and the effects of tail length and head group composition on the critical aggregation concentration (CAC), thermodynamic parameters, and minimum inhibitory concentration (MIC) against six bacterial strains were investigated. Synergistic antibacterial combinations of these amphiphiles were also identified. Amphiphiles in this study are composed of a benzene core with three benzylic ammonium bromide groups, two of which have alkyl chains, each 8-16 carbons in length. The third head group is a trimethylammonium or pyridinium. Log of critical aggregation concentration (log[CAC]) and heat of aggregation (ΔHagg) were both inversely proportional to the length of the linear hydrocarbon chains. Antibacterial activity increases with tail length until an optimal tail length of 12 carbons per chain, above which, activity decreased. The derivatives with two 12 carbon chains had the best antibacterial activity, killing all tested strains at concentrations of 1-2μM for Gram-positive and 4-16μM for Gram-negative bacteria. The identity of the third head group (trimethylammonium or pyridinium) had minimal effect on colloidal and antibacterial activity. The antibacterial activity of several binary combinations of amphiphiles from this study was higher than activity of individual amphiphiles, indicating that these combinations are synergistic. These amphiphiles show promise as novel antibacterial agents that could be used in a variety of applications. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: A series of novel spirohydantoin derivatives with arylpiperazinylbutyl moiety were synthesized and evaluated for serotonin 5-HT1A, 5-HT2A, 5-HT7 and dopamine D2 receptors. Based on these data, four compounds were selected for further binding affinity assays on dopamine D1, D3, D4, and 5-HT2C, 5-HT6 as well as adrenergic α1 and α2C receptors, which are involved in various CNS diseases such as schizophrenia, anxiety and/or depression. The compound 14, 1-{4-[4-(2-metoxyphe-nyl)piperazin-1-yl]butyl}-3',4'-dihydro-2H,2'H,5H-spiro[imidazolidine-4,1'-naphthalene]-2,5-dione, with the most promising functional profile, mixed 5-HT2A/D2 antagonist and 5-HT1A partial agonist, was selected. In the mouse d-amphetamine-induced locomotor hyperactivity model, compound 14 produced antipsychotic-like activity, which is devoid of cataleptogenic effects and in the forced swim test in mice, it showed a significant antidepressant-like effect unlike the reference drug aripiprazole.

    ABSTRACT: Drugs that target DNA topoisomerase II, such as the epipodophyllotoxin etoposide, are a clinically important class of anticancer agents. A recently published X-ray structure of a ternary complex of etoposide, cleaved DNA and topoisomerase IIβ showed that the two intercalated etoposide molecules in the complex were separated by four DNA base pairs. Thus, using a structure-based design approach, a series of bis-epipodophyllotoxin etoposide analogs with piperazine-containing linkers was designed to simultaneously bind to these two sites. It was hypothesized that two-site binding would produce a more stable cleavage complex, and a more potent anticancer drug. The most potent bis-epipodophyllotoxin, which was 10-fold more growth inhibitory toward human erythroleukemic K562 cells than etoposide, contained a linker with eight methylene groups. All of the mono- and bis-epipodophyllotoxins, in a variety of assays, showed strong evidence that they targeted topoisomerase II. COMPARE analysis of NCI 60-cell GI50 endpoint data was also consistent with these compounds targeting topoisomerase II. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: A new series of selective PDE4D inhibitors has been designed and synthesized by replacing 3-methoxy group with 3-difluoromethoxy isoster moiety in our previously reported cathecolic structures. All compounds showed a good PDE4D3 inhibitory activity, most of them being inactive toward other PDE4 isoforms (PDE4A4, PDE4B2 and PDE4C2). Compound 3b, chosen among the synthesized compounds as the most promising in terms of inhibitory activity, selectivity and safety, showed an improved pharmacokinetic profile compared to its non fluorinated analogue. Spontaneous locomotor activity, assessed in an open field apparatus, showed that, differently from rolipram and diazepam, selective PDE4D inhibitors, such as compounds 3b, 5b and 7b, did not affect locomotion, whereas compound 1b showed a tendency to reduce the distance traveled and to prolong the immobility period, possibly due to a poor selectivity.

    ABSTRACT: Six novel 3″-substituted (R)-N-(phenoxybenzyl) 2-N-acetamido-3-methoxypropionamides were prepared and then assessed using whole-cell, patch-clamp electrophysiology for their anticonvulsant activities in animal seizure models and for their sodium channel activities. We found compounds with various substituents at the terminal aromatic ring that had excellent anticonvulsant activity. Of these compounds, (R)-N-4'-((3″-chloro)phenoxy)benzyl 2-N-acetamido-3-methoxypropionamide ((R)-5) and (R)-N-4'-((3″-trifluoromethoxy)phenoxy)benzyl 2-N-acetamido-3-methoxypropionamide ((R)-9) exhibited high protective indices (PI=TD50/ED50) comparable with many antiseizure drugs when tested in the maximal electroshock seizure test to mice (intraperitoneally) and rats (intraperitoneally, orally). Most compounds potently transitioned sodium channels to the slow-inactivated state when evaluated in rat embryonic cortical neurons. Treating HEK293 recombinant cells that expressed hNaV1.1, rNaV1.3, hNaV1.5, or hNaV1.7 with (R)-9 recapitulated the high levels of sodium channel slow inactivation. Copyright © 2015.

    ABSTRACT: A series of caracasine acid (1) derivatives were synthesized and evaluated for their in vitro cytotoxicity on human cancer-derived cell lines MCF-7 and PC-3, as well as for other activities such as antibacterial, antileishmanial and antitrypanosomal activity. Compound 1 was more effective than any of its derivatives against tested human cancer cell lines. PC-3 cells were more sensitive than MCF-7 to all compounds, particularly the methyl ester (2), the amide (9) and the epoxide (10). The evaluation of antiparasitic activity revealed that ester derivatives (2-8) and the amide derivative (9) were the most effective antileishmanial and antitrypanosomal compounds, even though their effect on Trypanosoma cruzi was modest. Finally, compound 1 and the derivatives evidenced a broad spectrum of antibacterial activity, as assayed against Gram-positive and Gram-negative bacteria. Copyright © 2015 Elsevier Ltd.

    ABSTRACT: Carbonic anhydrases (CAs, EC 4.2.1.1) are metalloenzymes, mostly containing zinc within their active site, which catalyze a simple but physiologically relevant reaction in all life kingdoms, carbon dioxide hydration to bicarbonate and protons. Six CA classes (α, β, γ, δ, ζ and η) and multiple CA isoforms evolved in organisms all over the phylogenetic tree, for facing the need to efficiently convert high amounts of CO2 to its hydration products. These enzymes are thus involved in many physiologic processes, such as photosynthesis, respiration, CO2 transport, electrolyte secretion in many tissues/organs; biosynthetic reactions (gluconeogenesis, lipogenesis, ureagenesis), etc. Recently, our group reported a new technique to assay CA activity on SDS-PAGE gels, named 'protonography' due to its similarity to zymography. By using protonography, the conversion of CO2 into protons can be visualized as a yellow band on a polyacrylamide gel. By using this technique we demonstrated the possibility to detect activity of the α-CA from Vibrio cholerae as well as the β- and γ-CAs present in Escherichia coli extracts. Furthermore, the activity of the newly discovered η-class enzyme from Plasmodium falciparum has also been evidenced with protonography, illustrating its wide use. Here we show that protonography can be also useful to reveal the oligomeric state of the γ-CA identified in the genome of the bacterial parasite colonizing the oral cavity, Porphyromonas gingivalis, possibly allowing for a simple and efficient diagnostic method.

    ABSTRACT: The synthesis, biological and molecular modeling evaluation of a series of macrocyclic naphthalene diimides is reported. The present investigation expands on the study of structure-activity relationships of prototype compound 2 by constraining the molecule into a macrocyclic structure with the aim of improving its G-quadruplex binding activity and selectivity. The new derivatives, compounds 4-7 carry spermidine- and spermine-like linkers while in compound 8 the inner basic nitrogen atoms of spermine have been replaced with oxygen atoms. The design strategy has led to potent compounds stabilizing both human telomeric (F21T) and c-KIT2 quadruplex sequences, and high selectivity for quadruplex in comparison to duplex DNA. Antiproliferative effects of the new derivatives 4-8 have been evaluated in a panel of cancer cell lines and all the tested compounds showed activity in the low micromolar or sub-micromolar range of concentrations. In order to rationalize the molecular basis of the DNA G-quadruplex versus duplex recognition preference, docking and molecular dynamics studies have been performed. The computational results support the observation that the main driving force in the recognition is due to electrostatic factors. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: Synthetic routes to six 3-D scaffolds containing piperazine, pyrrolidine and piperidine cores have been developed. The synthetic methodology focused on the use of N-Boc α-lithiation-trapping chemistry. Notably, suitably protected and/or functionalised medicinal chemistry building blocks were synthesised via concise, connective methodology. This represents a rare example of lead-oriented synthesis. A virtual library of 190 compounds was then enumerated from the six scaffolds. Of these, 92 compounds (48%) fit the lead-like criteria of: (i) -1⩽AlogP⩽3; (ii) 14⩽number of heavy atoms⩽26; (iii) total polar surface area⩾50Å(2). The 3-D shapes of the 190 compounds were analysed using a triangular plot of normalised principal moments of inertia (PMI). From this, 46 compounds were identified which had lead-like properties and possessed 3-D shapes in under-represented areas of pharmaceutical space. Thus, the PMI analysis of the 190 member virtual library showed that whilst scaffolds which may appear on paper to be 3-D in shape, only 24% of the compounds actually had 3-D structures in the more interesting areas of 3-D drug space.

    ABSTRACT: A series of indole analogs that are synthesized using the scaffold of a potent radiosensitizer, YTR107, were tested for their ability to alter the solubility of phosphorylated nucleophosmin 1 (pNPM1). NPM1 is critical for DNA double strand break (DSB) repair. In response to formation of DNA DSBs, phosphorylated T199 NPM1 binds to ubiquitinated chromatin, in a RNF8/RNF168-dependent manner, forming irradiation-induced foci (IRIF) that promote repair of DNA DSBs. A Western blot assay was developed using lead molecule, YTR107, for the purpose of screening newly synthesized molecules that target pNPM1 in irradiated cells. A colony formation assay was used to demonstrate the radiosensitization properties of the compounds. Compounds that enhanced the extractability of pNPM1 upon radiation treatment possessed radiosensitization properties. Copyright © 2015 Elsevier Ltd. All rights reserved.

    ABSTRACT: In recent years, the hydroxyalkylphenols p-hydroxybenzyl alcohol and tyrosol, and the compound phloretin and its derivate phloridzin have been described as inhibitors of the enzyme tyrosinase. When the monophenolase and the diphenolase activities of tyrosinase on its physiological substrates l-dopa and/or l-tyrosine are measured in the presence of these compounds, the rate of action of the enzyme decreases. These findings led to the identification of these compounds as inhibitors. However, these molecules show an unusual behavior as inhibitors of the enzyme indeed, in this study, we demonstrate that they are not true inhibitors but alternative substrates of the enzyme.

    ABSTRACT: Here we report a series of plasmin inhibitors which were originally derived from the parent structure of 1 and 2. Our efforts focused on the optimization of the P4 moiety of 2 and on the quest of alternative scaffold to pyrrolopyrimidine in the parent compounds. The results of the former gave us pivotal information on the further optimization of the P4 moiety in plasmin inhibitors and those of the latter revealed that appropriate moieties extending from the benzimidazole scaffold engaged with S4 pocket in the active site of plasmin.
