Mouse aldehyde-oxidase-4 controls diurnal rhythms, fat deposition and locomotor activity

Aldehyde-oxidase-4 (AOX4) is one of the mouse aldehyde oxidase isoenzymes and its physiological function is unknown. The major source of AOX4 is the Harderian-gland, where the enzyme is characterized by daily rhythmic fluctuations. Deletion of the Aox4 gene causes perturbations in the expression of the circadian-rhythms gene pathway, as indicated by transcriptomic analysis. AOX4 inactivation alters the diurnal oscillations in the expression of master clock-genes. Similar effects are observed in other organs devoid of AOX4, such as white adipose tissue, liver and hypothalamus indicating a systemic action. While perturbations of clock-genes is sex-independent in the Harderian-gland and hypothalamus, sex influences this trait in liver and white-adipose-tissue which are characterized by the presence of AOX isoforms other than AOX4. In knock-out animals, perturbations in clock-gene expression are accompanied by reduced locomotor activity, resistance to diet induced obesity and to hepatic steatosis. All these effects are observed in female and male animals. Resistance to obesity is due to diminished fat accumulation resulting from increased energy dissipation, as white-adipocytes undergo trans-differentiation towards brown-adipocytes. Metabolomics and enzymatic data indicate that 5-hydroxyindolacetic acid and tryptophan are novel endogenous AOX4 substrates, potentially involved in AOX4 systemic actions.

Effects of diabetes on cholinergic transmission in two rat gut preparations

The gut may be a site of early diabetic neuropathy in humans and rats. The latter may provide appropriate models of these conditions. Therefore, cholinergic function was examined in two gut smooth muscle preparations from control, 30-day, and 6-month streptozotocin-diabetic and similarly diabetic rats that had received continuous treatment with an aldose reductase inhibitor, ponalrestat. Responses of terminal ileum longitudinal muscle to transmural nerve stimulation were depressed in preparations from untreated 30-day diabetic animals. Responses to exogenous acetylcholine were also depressed, by at least the same extent, in preparations from both 30-day and 6-month diabetic groups. Ponalrestat treatment prevented both changes in the 30-day study but did not prevent a depression of responses to acetylcholine in the 6-month study. Neither diabetes nor ponalrestat affected responses of esophageal muscularis mucosa to electrical stimulation or to exogenous acetylcholine. These observations suggest a change in the smooth muscle and/or noncholinergic innervation rather than in the cholinergic nerves of the ileal preparation. Cholinergic function in the ileum did not, therefore, seem to be an appropriate model of diabetic neuropathy.

Challenges and Opportunities with Non-CYP Enzymes Aldehyde Oxidase, Carboxylesterase, and UDP-Glucuronosyltransferase: Focus on Reaction Phenotyping and Prediction of Human Clearance

Over the years, significant progress has been made in reducing metabolic instability due to cytochrome P450-mediated oxidation. High-throughput metabolic stability screening has enabled the advancement of compounds with little to no oxidative metabolism. Furthermore, high lipophilicity and low aqueous solubility of presently pursued chemotypes reduces the probability of renal excretion. As such, these low microsomal turnover compounds are often substrates for non-CYP-mediated metabolism. UGTs, esterases, and aldehyde oxidase are major enzymes involved in catalyzing such metabolism. Hepatocytes provide an excellent tool to identify such pathways including elucidation of major metabolites. To predict human PK parameters for P450-mediated metabolism, in vitro-in vivo extrapolation using hepatic microsomes, hepatocytes, and intestinal microsomes has been actively investigated. However, such methods have not been sufficiently evaluated for non-P450 enzymes. In addition to the involvement of the liver, extrahepatic enzymes (intestine, kidney, lung) are also likely to contribute to these pathways. While there has been considerable progress in predicting metabolic pathways and clearance primarily mediated by the liver, progress in characterizing extrahepatic metabolism and prediction of clearance has been slow. Well-characterized in vitro systems or in vivo animal models to assess drug-drug interaction potential and intersubject variability due to polymorphism are not available. Here we focus on the utility of appropriate in vitro studies to characterize non-CYP-mediated metabolism and to understand the enzymes involved followed by pharmacokinetic studies in the appropriately characterized surrogate species. The review will highlight progress made in establishing in vitro-in vivo correlation, predicting human clearance and avoiding costly clinical failures when non-CYP-mediated metabolic pathways are predominant.

Water and organic synthesis: A focus on the in-water and on-water border. Reversal of the in-water breslow hydrophobic enhancement of the normal endo -effect on crossing to on-water conditions for huisgen cycloadditions with increasingly insoluble organic liquid and solid 2pi-dipolarophiles

Measurements of the endo/exo product ratios for Huisgen cycloadditions with a series of vinyl ketones, alkyl acrylates, and substituted styrenes as dipolarophiles with phthalazinium and pyridazinium dicyanomethanide 1,3-dipoles in acetonitrile and water show that as the reactions change from in-water (large hydrophobic enhancement of endo-products) to on-water, the hydrophobic enhancement of the endo-products is reduced and partially reversed (relative to acetonitrile). An expected increase of the endo-effect with increasing hydrophobic character of the dipolarophile is overcome by decreasing water solubility causing changeover to on-water conditions. On-water reactions do not show increased cycloaddition endo-effects (relative to organic solvents) as do in-water reactions.

Synthesis and antimycobacterial evaluation of novel phthalazin-4- ylacetamides against log- and starved phase cultures: Research article

Twenty four novel 2-[3-(4-bromo-2-fluorobenzyl)-4-oxo-3,4-dihydro-1- phthalazinyl]acetic acid amides were synthesized from phthalic anhydride and were subjected to in vitro and in vivo evaluation against log- and starved phase of mycobacterial species and Mycobacterium tuberculosis isocitrate lyase enzyme inhibition studies. Among the compounds screened, 2-(2-(4-bromo-2-fluorobenzyl) -1,2-dihydro-1-oxophthalazin-4-yl)-N-(2,6-dimethylphenyl)acetamide (5j) inhibited all eight mycobacterial species with MIC’s ranging from 0.08 to 5.05 mum and was non-toxic to Vero cells till 126.43 mum. Four compounds were tested against starved culture of Mycobacterium tuberculosis and they inhibited with MIC’s ranging from 3.78 to 23.2 mum. Some compounds showed 40-66% inhibition against Mycobacterium tuberculosis isocitrate lyase enzyme at 10 mum. The docking studies also confirmed the binding potential of the compounds at the isocitrate lyase active site. In the in vivo animal model, 5j reduced the mycobacterial load in lung and spleen tissues with 1.38 and 2.9-log10 protections, respectively, at 25 mg/kg body weight dose.

Novel luminol-isoluminol derivatives containing o-hydroxyphenyl benzimidazole unit were synthesized from aromatic aldehydes and diaminophthalates followed by heating under reflux with hydrazine hydrate. The chemiluminescent properties were studied in hydrogen peroxide, potassium hexacyanoferrate(III) and sodium hydroxide solution. The chemiluminescence properties were compared with the standard luminol and isoluminol systems it was observed that the chemiluminescence properties of the novel derivatives were superior to luminol and isoluminol. Density Functional Theory computations have been used in order to have a greater understanding of the structural, molecular, electronic and photophysical properties. The experimental absorption and emission wavelength values were in good agreement with the computed vertical excitation and emission values.
