Oral Hypoglycemic Agents. Discovery and Structure-Activity Relationships of Phenacylimidazolium Halides

Blood glucose levels in viable, yellow, obese, diabetic mice are reduced following oral administration of phenacylimidazolium halides.Compounds 2 and 3 produced reductions of ca. 40percent 2 h after doses of 100 mg/kg po.Since these mice do not respond to sulfonylureas, the glucose-lowering activity of phenacylimidazolium salts in this model suggests a mechanism other than that of stimulating insulin secretion.Only phenacylimidazolium halides with electron-donating groups were active; other azolium salts or variations in the phenacyl portion (alterations in the keto function; chain lengthening or extensive branching) produced inactive compounds.

Absorption and fluorescence spectra of organic compounds from 40 sources: Archives, repositories, databases, and literature search engines

Absorption and fluorescence spectra are foundational data for studies in photochemistry as well as any area of science or technology that entails electronic spectroscopy. The data of interest include the spectra (graphs of intensity as a function of wavelength or wavenumber), the respective quantitative photophysical parameters-molar absorption coefficient [(lambda)] and the fluorescence quantum yield [Phif]- A nd the conditions under which the data were obtained. Yet such qualitative and quantitative data are scattered across a wide landscape. Modern search engines provide access to much of the world’s published scientific literature (<108 articles) spanning <100 years but are surprisingly ineffective at pinpointing spectra and companion photophysical parameters. Manual curation has led to valuable collections albeit of uneven contents: Some include spectra, others include only listings of spectral data (e.g., positions of peak intensity [lambdamax]), and many are not available in digital form. Numerous calculations in photophysics, such as propensity for Foerster resonance energy transfer (FRET), require spectra and cannot be carried out with tabular listings of values of lambdamax, (lambda) and Phif. Here, we summarize the spectral data available in 27 printed archives (beginning in the early 20th century), in repositories or databases at a dozen dedicated websites, and via scholarly literature search tools. The websites and search tools include PubChem, ChemSpider, NIST Chemistry WebBook, SciFinder, Reaxys, Google Scholar, Microsoft Academic, and Web of Science. This work is part of a long-term project to organize and assemble the world of spectral data for the molecular photosciences. Do you like my blog?

Low-field Photochemically Induced Dynamic Nuclear Polarization (Photo-CIDNP) of Diazanaphthalenes

Photoreduction of some diazanaphthalenes in proton-donor solvents has been investigated by means of chemically induced nuclear polarization (CIDNP).While very few polarizations are observed during irradiation in a high magnetic field, CIDNP spectra recorded after the samples have been irradiated in a weak magnetic field demonstrate strong polarizations due to the solvent and the starting compounds.Polarizations due to the addition products are also observed.Using the Den Hollander rule for low magnetic fields we affirmed that the principal radical pair of the photoreaction is formed by the abstraction of a hydrogen of the solvent by the nitrogen heterocycles excited in the triplet state.The validity of our results was then confirmed by a study of the photoreduction of acridine in a weak field using the experimental procedures described.

Recent Advances Toward Robust N-Protecting Groups for Glucosamine as Required for Glycosylation Strategies

2-Amino-2-deoxy-D-glucose (D-glucosamine) is among the most abundant monosaccharides found in natural products. This constituent, recognized for its ubiquity, is presented in most instances as its N-acetyl derivative 2-acetamido-2-deoxy-D-glucopyranose (N-acetylglucosamine, GlcNAc, NAG). It occurs as the beta-linked pyranosyl group in polysaccharides and oligosaccharides, and sometimes as the monosaccharide itself, either in its native state or as a glycoconjugate. The compound’s acylation profile and other aspects of its structure are important elements in determining the variety of reactivities and functions of the molecule as a whole. Methods elaborated to investigate these challenges have been intensively reviewed; however, a relatively more comprehensive reviewing of this subject is introduced here to cover some aspects that have not been sufficiently covered. This might enable those who are beginners in this field to be aware of the subject in a more comprehensive context. 2-Amino-2-deoxy-D-glucosylation strategies demand robust amino-protecting groups that survive under a variety of chemical conditions, yet provide groups that can be deprotected under relatively mild conditions. At the end of this review, a table that includes all the N-protecting groups that have been used for glucosamine is provided to introduce them at a glance to aid in constructing building blocks that will act as useful 2-amino-2-deoxy-D-glucosyl donors.

Intervention against the Maillard reaction in vivo

The field of Maillard/glycation reactions in vivo has grown enormously during the past 20 years, going from 25 to 500 publications per year. It is now well recognized that many of the “advanced” products form oxidatively or anaerobically and can have deleterious effects on macromolecular and biological function. The feasibility of developing pharmacological agents with beneficial in vivo properties, based on in vitro inhibition of glycation, has been surprisingly successful. This Editorial sets the stage for a series of articles by experts in the field, who have made key contributions to our understanding of the Maillard reaction in vivo.

Data on the NADPH-oxidase activity induced by WKYMVm and galectin-3 in bone marrow derived and exudated neutrophils isolated from four different mouse strains

Neutrophils are the key players in inflammatory reactions and the release of superoxide through the NADPH-oxidase upon neutrophil activation contributes to bacterial clearance and surrounding tissue damage. Here we describe data on the mouse neutrophil NADPH-oxidase activation induced by the mouse formyl peptide receptor (Fpr) agonist WKYMVm and galectin-3. Neutrophils isolated from bone marrow, peritoneal exudated, and in vitro TNFalpha primed bone marrow neutrophils from four different laboratory strains (C57BL/6, DBA/1, BALB/c and NMRI) were used. Both Fpr agonist and galectin-3 activated neutrophils to release superoxide. No differences were observed in the amounts of superoxide released from neutrophils derived from four different strains.

2-chloro-4,5-dihydroimidazole, 8: Syntheses of novel fused heterocyclic systems by reactions of 1,2-dihydro-2-(4,5-dihydroimidazol-2-yl)phthalazin-1-ol with active methylene compounds

Three-component reactions of 1 with pyridazine or phthalazine afforded the 1,2-dihydro derivatives 2a and 2b, respectively. A similar reaction of 1 with phthalazine performed in aqueous NaOH led to the formation of pseudobase 3. The latter compound proved to be an excellent substrate for the preparation of a series of novel 1,2-dihydrophthalazine derivatives 4a-c, 5 as well as 6a-b by reactions with a variety of active methylene compounds.
