Convergent synthesis of 4,6-unsubstituted 5-acy1-2aminodihydropyrimidines using Weinreb amide

A method of convergent synthesis of novel 4,6-unsubstituted 5-acyl-2-aminodihydropyrimidines 7 is developed. The synthetic intermediate of 7, 4,6-unsubstituted 2-aminodihydropyrimidines 9 having a Weinreb amide at the 5-position, is prepared by the sequential Staudinger/aza-Wittig/cyclization reactions of (E)-tert-buty1{3-azido-2-Imethoxy(methyl)carbamoyljallyl}carbamate (E)-10. The transformation of the Weinreb amide of 9 to an acyl group proceeds smoothly by a substitution reaction using aryllithiums or alkyllithiums in the presence of a catalytic amount of BF3 etherate, affording 7 in good to high yield. The N-protecting group of 7 can be easily removed to obtain N-unsubstituted 2-amino5-acyldihydropyrimidines 8, and the derivatives are observed as a single isomer in H-1 NMR spectroscopy. All dihydropyrimidines in this study were hitherto unavailable and difficult to synthesize by conventional methods. (C) 2017 Elsevier Ltd. All rights reserved.

Does a Conjugation Site Affect Transport of Vitamin B-12-Peptide Nucleic Acid Conjugates into Bacterial Cells?

Gram-negative bacteria develop specific systems for the uptake of scarce nutrients, including vitamin B-12. These uptake pathways may be utilized for the delivery of biologically relevant molecules into cells. Indeed, it was recently reported that vitamin B-12 transported an antisense peptide nucleic acid (PNA) into Escherichia coli and Salmonella Typhimurium cells. The present studies indicate that the conjugation site of PNA to vitamin B-12 has an impact on PNA transport into bacterial cells. Toward this end, a specifically designed PNA oligomer has been tethered at various positions of vitamin B-12 (central Co, R-5 ‘-OH, c and e amide chains, meso position, and at the hydroxy group of cobinamide) by using known or newly developed methodologies and tested for the uptake of the synthesized conjugates by E. coli. Compounds in which the PNA oligonucleotide was anchored at the R-5 ‘-OH position were transported more efficiently than that of other compounds tethered at the peripheral positions around the corrin ring. Of importance is the fact that, contrary to mammalian organisms, E. coli also takes up cobinamide, which is an incomplete corrinoid. This selectivity opens up ways to fight bacterial infections.

Elevation of arachidonoylethanolamide levels by activation of the endocannabinoid system protects against colitis and ameliorates remote organ lesions in mice

The endocannabinoid system (ECS) is a potential pharmaceutical target for the treatment of inflammatory bowel diseases (IBDs). The aim of this study was to explore the effects of activation of the ECS on IBD and the associated neural inflammation-induced disruption of the blood-brain barrier (BBB). In a mouse model of trinitrobenzene sulfonic acid-induced colitis, the inhibition of fatty acid amide hydrolase with URB597 elevated the arachidonoylethanolamide concentration of the colon. Macroscopic alterations of the colons were evaluated, and the 7-day survival rate of mice was analyzed. BBB integrity was assessed using a dye tracer method, and the cognitive function of mice was examined using a fear-conditioning test. URB597 treatment significantly reduced macroscopic alterations of the colon, decreased the mortality rate, and protected the integrity of the BBB in the mice (P<0.05). No significant changes were observed in the cognitive functions of the mice (P>0.05); therefore, the neuroprotective effect of ECS in this colitis model requires further investigation. Activation of the ECS was efficient in ameliorating colitis and increasing the survival rate of the mice, and reducing remote organ changes induced by colitis. The results suggest that modulation of the ECS is a potential therapeutic approach for IBDs and the associated remote organ lesions.

Topological control of supramolecular crystal structures of phenylene bis-monothiooxamate derivatives and in vitro anticancer activity

This paper describes the synthesis, physical characterization, X-ray crystal structures and antitumoral activity against human carcionogenic cells of three new diethyl ester acid derivatives of phenylene bismonothiooxamate compounds, namely Et2H2opbta (1), Et(2)H(2)mpbta (2) and Et(2)H(2)ppbta (3) [opbta = N,N’-1,2-phenylenebis(2-thiooxamate), mbpta = N,N’-1,3-phenylenebis(2-thiooxamate) and ppbta = N,N’-1,4-phenylenebis(2-thiooxamate)]. Compounds 1-3 were obtained under mild conditions by reaction of the corresponding N,N’-phenylenebis(oxamate) analogues and Lawesson’s reagent resulting in the formation of C=S bonds at the carbonyl amide functions. Crystal structures of 1-3 consist of 1D supramolecular assemblies of centrosymmetric H2Et2ppbta (3) or noncentrosymmetric chiral H(2)Et(2)opbta (1) and H(2)Et(2)mpbta (2) molecules with opposite helical chirality (M and P enantiomers) resulting from intermolecular N H center dot center dot center dot O (1 and 3) or N H center dot center dot center dot S (2) hydrogen bonds between the amide hydrogen atoms and the carbonyl ester oxygen or thionyl amide sulfur atoms from the thiooxamate moieties respectively, together with weak S center dot center dot center dot S bonds between the thionyl amide sulfur atoms (1). The cytotoxicity of H(2)Et(2)xpbta [x = o (1), m (2) and p (3)] against chronic myelogenous leukemia cells was evaluated and the bioactivity follows the order 1 >> 2 > 3, compound 1 being six and ten times more active than 2 and 3, respectively.

Computational and Experimental Study of Turbo-Organomagnesium Amide Reagents: Cubane Aggregates as Reactive Intermediates in Pummerer Coupling

The dynamic equilibria of organomagnesium reagents are known to be very complex, and the relative reactivity of their components is poorly understood. Herein, a combination of DFT calculations and kinetic experiments is employed to investigate the detailed reaction mechanism of the Pummerer coupling between sulfoxides and turbo-organomagnesium amides. Among the various aggregates studied, unprecedented heterometallic open cubane structures are demonstrated to yield favorable barriers through a concerted anion-anion coupling/ S-O cleavage step. Beyond a structural curiosity, these results introduce open cubane organometallics as key reactive intermediates in turbo-organomagnesium amide mixtures.

Development of alginate gel beads with a potential use in the treatment against acute lead poisoning

The objective was to develop alginate beads that could adsorb lead ions in gastric pH, in view to preconize their use in gastric lavage following lead poisoning. The swelling measurements of both, dry and hydrated beads, were carried out in simulated gastric fluid (SGF). The sorption kinetics was examined at lead concentrations ranging from 50 to 200 mg/l. Calcium released during the sorption process was investigated. The swelling rate of the dry beads increased considerably with time increase and reached the equilibrium at 736% after 240 min; concerning the hydrated beads, the equilibrium swelling reached 139% after 180 min. The adsorption of Pb (II) in SGF by dry beads increased with the increase of time and initial lead concentration. The adsorption kinetics of Pb ions by hydrated alginate beads indicated a rapid binding of Pb ions to the sorbent during the first 15 min for all the concentrations, followed by a slow increase until the equilibrium was reached after 90 min. The adsorption capacity of Pb ions increased with the increase of the storage time in water at 4 degrees C and with the weight. The amount of Ca2+ released by the beads increased with the increase of Pb ions a rate. (C) 2017 Elsevier B.V. All rights reserved.

Persistence, mobility, and leaching risk of flumioxazin in four Chinese soils

Purpose Flumioxan was used to control annual broad-leaved and dicotyledonous weeds. Considering the limited information available, comprehensive investigation of persistence and mobility of flumioxazin in Chinese soil is very important. Materials and methods The degradation, adsorption-desorption, mobility, and leaching risk of flumioxazin in four Chinese soils were investigated under laboratory conditions. Results and discussion The degradation rates of flumioxazin, which correlated with soil moisture, microorganisms, organic matter and pH, were 8.2-50.6 days in the four soils under different conditions. Microorganisms influenced these rates greatly, with half-lives increasing 1.67-2.39-fold. Three possible metabolites were detected by ultrahigh-performance liquid chromatography with high-resolution mass spectrometry, and the metabolic pathways were cleavage of the imide and amide linkages and opening of the cyclic imide. The adsorption capacity of flumioxazin in soil was strongly positively correlated with the soil’s cation exchange capacity (CEC) and organic matter (OM) content, which had correlation coefficients > 0.83. Negative and positive desorption hysteresis effects were observed in Guizhou soil and the other three soils, respectively, which might be related to the different soil constitutions. The mobility was relatively weak in the four Chinese soils and negatively related to CEC and OM content, with correlation coefficients > 0.86. Moreover, the leaching risk of flumioxazin was uncertain for the underground water. Conclusions The results indicated that flumioxazin was a low-risk herbicide and could be used to evaluate the environmental fate and risk of flumioxazin in soil.
