Hydantoin Bioisosteres. In Vivo Active Hydroxy Acetic Acid Aldose Reductase Inhibitors

The hypothesis that clinical side effects of the aldose reductase inhibitor (ARI) sorbinil were related to its hydantoin ring led to a bioisosteric analysis and replacement of the hydantoin by a spiro hydroxy acetic acid moiety as in 40.These hydroxy acids, compared to hydantoins, showed a similar potency increase on chroman 2-methyl substitution, a similar orthogonal relationship of acidic to aromatic moieties, and similar ARI enantioselectivity.In this series the six-membered spiro hydroxy acetic acid anion array is a bioisostere for a spiro hydantoin anion and leads to ARIs with excellent in vivo activity.In vitro and in vivo activity was improved over 40 by chroman cis 2-methylation as in 4 and by aromatic 6,7-halogen substitution.Compounds with the best acute in vivo activity in rats were compared for chronic in vivo activity.The highest tissue levels and best chronic in vivo activities were found in the racemic 6,7-dichloro and 6-fluoro-7-chloro analogues 18 and 23.ARI activity was enantioselective for 58 and 60, the 2R,4R-enantiomers of 18 and 23. 7-Chloro-6-fluoro-cis-4-hydroxy-2(R)-methyl-chroman-4-acetic acid (60) was selected for phase 1 clinical trials and did not exhibit sorbinil-like hypersensitivity side effects.

Design, synthesis, and biological evaluation of a series of benzo[ de ][1,7]naphthyridin-7(8 H)-ones bearing a functionalized longer chain appendage as novel PARP1 inhibitors

A series of benzo[de][1,7]naphthyridin-7(8H)-ones possessing a functionalized long-chain appendage have been designed and evaluated as novel PARP1 inhibitors. The initial effort led to the first-generation PARP1 inhibitor 26 bearing a terminal phthalazin-1(2H)-one framework and showing remarkably high PARP1 inhibitory activity (0.31 nM) but only moderate potency in the cell. Further effort generated the second-generation lead 41, showing high potency against both the PARP1 enzyme and BRCA-deficient cells, especially for the BRCA1-deficient MDA-MB-436 cells (CC50 < 0.26 nM). Mechanistic studies revealed that the new PARP1 inhibitors significantly inhibited H 2O2-triggered PARylation in SKOV3 cells, induced cellular accumulation of DNA double-strand breaks, and impaired cell-cycle progression in BRCA2-deficient cells. Significant potentiation on the cytotoxicity of Temozolomide was also observed. The unique structural character and exceptionally high potency of 41 made it stand out as a promising drug candidate worthy for further evaluation.

Study of the anomalous thermochemical behavior of 1,2-diazines by correlation-Gas chromatography

The vaporization enthalpies and liquid vapor pressures of quinoxaline, quinazoline, phthalazine, benzo[c]cinnoline, 1,10-phenanthroline, phenazine, and triphenylamine are measured by correlation-gas chromatography and compared to values calculated from available literature vaporization, sublimation, and fusion enthalpy data. Good agreement with the literature is observed for all compounds except the 1,2-diazines and the sublimation enthalpy of triphenylamine. The results suggest that liquid 1,2-diazines exhibit an additional intermolecular stabilizing interaction of approximately 6 kJ¡¤mol-1 not present in other diazine isomers.

Low-level laser therapy stimulates the oxidative burst in human neutrophils and increases their fungicidal capacity

Low-level laser therapy (LLLT) is known to enhance mitochondrial electron transfer and ATP production; thus, this study asked whether LLLT could stimulate the oxidative burst in human neutrophils (PMN) and improve their ability to kill microorganisms. Blood from healthy human subjects was collected and PMN were isolated from the samples. PMN were treated in vitro with 660?nm or 780?nm CW laser light at 40?mW power and increasing energies up to 19.2?J and were subsequently incubated with Candida albicans cells. Generation of hydroxyl radicals, hypochlorite anions and superoxide anions by PMN were checked using fluorescent probes and chemiluminescence assays; a microbicidal activity assay against C. albicans was also performed. LLLT excited PMN to a higher functional profile, which was translated as superior production of reactive oxygen species (ROS) and increased fungicidal capacity. The most efficacious energy was 19.2?J and, interestingly, the 660?nm light was even more efficacious than 780?nm at increasing the respiratory burst of PMN and the fungicidal capacity. (Figure presented.) Human neutrophils (PMN) were stimulated in vitro with 660?nm or 780?nm CW laser light at 40?mW of power and a total energy of 19.2?J. Low-level laser therapy (LLLT) excited PMN to a higher functional profile, which was translated as a superior production of reactive oxygen species (ROS) such as hydroxyl radicals (HO?) and hypochlorite anions (ClO?) (Figure) and increased fungicidal capacity against Candida albicans cells.

Antidiabetic potential of methanol extracts from leaves of Piper umbellatum L. and Persea americana Mill.

Objective: To determine inhibitory activity of methanolic leaf extract of Piper umbellatum and Persea americana (P. americana) (traditionally used in Cameroon against diabetes) on alpha-glucosidase, beta-glucosidase, maltase-glucoamylase, aldose reductase and aldehyde reductase activities, enzymes involved in starch digestion or diabetic complications. Methods: The methanol extracts from Piper umbellatum and P. americana were prepared by maceration. To assess relative efficacy of these extracts, the determination of concentrations that were needed to inhibit 50% of enzyme activity was done, whereas, gas chromatography-mass spectrum was used to identify components from extracts that may be responsible for the activities. Results: The tested extracts strongly inhibited alpha-glucosidase, maltase-glucoamylase, aldose reductase and aldehyde reductase activities with IC50 ranging from (1.07 ¡À 0.03) to (31.77 ¡À 1.17) mug/mL. Among the tested extracts, P. americana was the most active against sensitive enzymes (IC50 of 1.07 ¡À 0.03 to 15.63 ¡À 1.23). But, none of the extracts showed interesting inhibitory effect against beta-glucosidase as their percentage inhibitions were less than 16%. From gas chromatography-mass spectrum analysis, 10 and 8 compounds were identified in Piper umbellatum and P. americana extracts respectively, using NIST library 2014. Conclusions: Results of this study provide the scientific credential for a prospective usage of these plants to treat diabetes.

Copper(II) complexes with aromatic nitrogen-containing heterocycles as effective inhibitors of quorum sensing activity in: Pseudomonas aeruginosa

Five copper(ii) complexes 1-5 with aromatic nitrogen-containing heterocycles, pyrimidine (pm, 1), pyrazine (pz, 2), quinazoline (qz, 3 and 4) and phthalazine (phtz, 5) have been synthesized and structurally characterized by spectroscopic and single-crystal X-ray diffraction techniques. The crystallographic results show that, dependent on the ligand structure, complexes 1-5 are of different nuclearity. The antimicrobial efficiency of complexes 1-5 has been evaluated against three clinically relevant microorganisms and none of the complexes showed significant growth inhibiting activity, with values of minimum inhibitory concentrations (MIC) in the mM range. Since in many bacteria, pathogenicity and virulence are regulated by intercellular communication processes, quorum sensing (QS), the effect of the copper(ii) complexes on bacterial QS has also been examined. The results indicate that the investigated complexes inhibit violacein production in Chromobacterium violaceum CV026, suggesting an anti-QS activity. In order to differentiate, which of the QS pathways was affected by the copper(ii) complexes, three biosensor strains were used: the PAO1 DeltarhlIpKD-rhlA and the PA14-R3DeltalasIPrsaI lux strain to directly measure the levels of C4-HSL (N-butanoyl-homoserine lactone) and 3OC12-HSL (N-3-oxo-dodecanoyl-homoserine lactone), respectively, and PAO1 DeltapqsA mini-CTX luxPpqsA for the detection of AHQs (2-alkyl-4-quinolones). Complexes 1-5 were shown to be efficient inhibitors of biofilm formation of the human opportunistic pathogen Pseudomonas aeruginosa PAO1, with the qz-containing complex 3 being the most active. Finally, the most anti-QS-active complexes 1 and 3 showed synergistic activity against a multi-drug resistant clinical isolate of P. aeruginosa, when supplied in combination with the known antibiotics piperacillin and ceftazidime.

Ultrasensitive detection of hazardous reactive oxygen species using flexible organic transistors with polyphenol-embedded conjugated polymer sensing layers

Here we report that superoxide, one of the hazardous reactive oxygen species (ROS), can be quickly detected by flexible organic field-effect transistors (OFETs) with the polyphenol-embedded conjugated polymer micro-channels. Rutin, one of the abundant polyphenols found in a variety of plants, was employed as a sensing molecule and embedded in the poly(3-hexylthiophene) (P3HT) matrix. The rutin-embedded P3HT layers showed randomly distributed micro-domains, which became bigger as the rutin content increased. The best transistor performance was achieved at the rutin content of 10 wt%, while the OFETs exhibited proper and controllable transistor performances even in the phosphate buffer solutions. The sensing test revealed that the present OFET sensors could stably detect superoxide using very small amount (<10 mul) of samples at extremely low concentrations (500 pM), while they exhibited outstanding stability and durability upon repeated detection and storage-reuse tests. Finally, the present flexible OFET sensors could deliver confident sensing results for the detection of superoxide generated from the mouse RAW264.7 macrophages.

Polynuclear coordination complexes – From dinuclear to nonanuclear and beyond

Polytopic ligands based on aromatic or open chain diazine and alkoxo-fragments form an ideal focus for the simultaneous coordination of metal centers in contiguous groupings, juxtaposed closely enough that magnetic spin-spin exchange occurs between adjacent pairs of metal ions. Examples of polynuclear complexes Mn (n = 2-9) will be discussed in terms of their structures, and principally their magnetic properties, with a focus on self-assembly reactions. Ligand design elements that lead to predictable cluster and grid structures will be emphasized. Magneto-structural studies and correlations will be highlighted with antiferromagnetic and ferromagnetic examples, in addition to recent studies with high nuclearity grids and clusters. Ferromagnetic grids with high spin ground states present exciting possibilities for applications of these nano-scale molecular systems in, e.g. information storage technology.

Ionic liquid catalysed multicomponent synthesis, antifungal activity, docking studies and in silico ADMET properties of novel fused Chromeno-Pyrazolo-Phthalazine derivatives

A series of novel chromeno-pyrazolo[1,2-b]phthalazine-6,9,14(7H)-trione derivatives (4a?k) were designed and prepared using a reusable and efficient catalyst ionic liquid [Bmim]BF4 via one-pot multi-component reaction. Their bioactivity was evaluated against Aspergillus niger and Candida albicans in vitro. Compound 4f was found to be the most effective compared to all other synthesised compounds. To validate experimental biological data obtained, molecular docking study was carried out. It was observed that compound 4f showed stronger binding interactions with secreted aspartic proteinase (SAP) of C. albicans (1EAG). Further, primary optimisation of drug-like properties was studied through in silico predictions by using ADMET predictor FAFdrug2 and OSIRIS property explorer.
