CHIRAL ACETYLENES AS SYNTHETIC INTERMEDIATES. V. A REINVESTIGATION ON THE SYNTHESIS OF OPTICALLY ACTIVE ISOXAZOLES

The synthesis of 3- or 5-alkyl isoxazoles and pyrazoles has been achieved starting from alkyl-substituted acetylenic ketones: the influence of the structure of the carbonyl compound on the isomeric composition of the heterocyclic compound has been studied.Some optically active monoalkyl-substituted isoxazoles have also been prepared: in this context, an investigation on the stereochemistry of the cyclization process has been carried out.

Generation of Nitrile Oxides via O-Tributylstannyl Aldoximes; Application to the Synthesis of Isoxazolines and Isoxazoles

Nitrile oxides were generated readily by the reaction of aldoximes 1, with tert-butyl hypochlorite and bis(tributyltin) oxide.The reaction proceeded efficiently under mild conditions, in which O-stannylated aldoximes 2 are thought to be key intermediates.This reaction system was applicable to the one-pot syntheses of isoxazole derivatives 4 and 5 in the presence of dipolarophiles via a <3 + 2> cycloaddition.

4-N-alkyl-arylamino-1,2-naphthochinon-1/2-dinitrophenylhydrazones – Structure and colour

The condensation products from 4-dialkylamino-1,2-naphthoquinones 2 with 2,4-dinitrophenylhydrazin (3) are thought to be as chelates 8/9. Therefore arylhydrazones 4/5 and corresponding azocompounds 6/7 can be seen as mesomeric structures. The different colours of 8 and 9 are caused by the alternative enamin-/phenylen-connection with the chelat chromophor. The colour of the arylhydrazones of 4-N-alkyl-arylamino-1,2-naphthoquinones 2b-d are similar to those of 8/9. Those of the phenylogous aminonaphthoquinone 13a are of different colour.

Synthesis of Spirofurooxindoles via Phenyliodine(III) Bis(trifluoroacetate) (PIFA)-Mediated Cascade Oxidative C?O and C?C Bond Formation

Upon treatment with solely a hypervalent iodine reagent of phenyliodine(III) bis(trifluoroacetate) (PIFA), 3-(2-hydroxyphenyl)-3-oxo-N-phenyl propanamides and a series of its derivatives were conveniently converted to a class of undocumented spirofurooxindoles under mild conditions.

A chiral-At-metal asymmetric catalyzed vinylogous Michael addition of: Ortho-methyl aromatic nitro compounds for isoxazole derivative synthesis

ortho-Alkyl aromatic nitro compounds as vinylogous nucleophiles in catalytic asymmetric synthesis have rarely been reported. Herein an asymmetric vinylogous Michael addition of 5-methyl 4-nitroisoxazoles with alpha,beta-unsaturated 2-Acyl imidazoles catalyzed by a chiral-At-metal rhodium(iii) complex has been developed. The corresponding adducts were obtained in good yields (80-96%) with excellent enantioselectivities (up to 97%). The reaction can be conducted on a gram scale with a low catalyst loading (0.25 mol%) without impacting its efficiency.

Stacking Interactions between 9-Methyladenine and Heterocycles Commonly Found in Pharmaceuticals

Complexes of 9-methyladenine with 46 heterocycles commonly found in drugs were located using dispersion-corrected density functional theory, providing a representative set of 408 unique stacked dimers. The predicted binding enthalpies for each heterocycle span a broad range, highlighting the strong dependence of heterocycle stacking interactions on the relative orientation of the interacting rings. Overall, the presence of NH and carbonyl groups lead to the strongest stacking interactions with 9-methyadenine, and the strength of -stacking interactions is sensitive to the distribution of heteroatoms within the ring as well as the specific tautomer considered. Although molecular dipole moments provide a sound predictor of the strengths and orientations of the 28 monocyclic heterocycles considered, dipole moments for the larger fused heterocycles show very little correlation with the predicted binding enthalpies.

Anti-inflammatory activity of Syzygium aromaticum silver nanoparticles: In vitro and in silico study

Objective: In the present study, antioxidant and anti-inflammatory activity of Syzygium aromaticum (clove) silver nanoparticles (clove AgNP?s) was evaluated. Methods: Gas chromatography-mass spectrometry technique was used to identify the compounds present in the aqueous extract of clove. Fourier transform infrared (FT-IR) analysis was done to characterize the clove silver AgNP?s. 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay was performed to evaluate the antioxidant property of nanoparticles (0.05 and 0.25 mg/ml) and aqueous extracts (0.05, 0.1, and 0.25 mg/ml) of clove. The antiinflammatory property of the clove AgNP?s was determined by inhibition of protein denaturation and downregulation of interleukin-1 beta. In silico molecular docking studies was performed using Schrodinger Maestro software. Results: Eugenol was found to be highest with 16.27%. The AgNP?s exhibited dose-dependent antioxidant property. AgNP?s scavenged 80% of radical at the concentration of 0.25 mg/ml. The scavenging activity of AgNP?s markedly increased when compared to aqueous extract at the same concentration. Inhibition of protein denaturation assay also revealed AgNP?s showing the highest activity (66%) when compared with drug aspirin (55%) and aqueous extract (56%). In the enzyme-linked immunosorbent assay (ELISA) method, AgNP?s showed better inhibition (80%) when compared to aqueous extract (60%). Among 15 compounds, two compounds (eugenol and methyl 14-methylpentadecanoate) showed good glide energy, docking score, and hydrogen-bonded active site interactions with the protein interleukin-1 beta. Conclusion: As AgNP?s were more active than the aqueous extract, it may be considered for pharmacological activity against inflammatory disorders.

The antifungal activity of naphthoquinones: An integrative review

Naphthoquinones are the most commonly occurring type of quinones in nature. They are a diverse family of secondary metabolites that occur naturally in plants, lichens and various microorganisms. This subgroup is constantly being expanded through the discovery of new natural products and by the synthesis of new compounds via innovative techniques. Interest in quinones and the search for new biological activities within the members of this class have intensified in recent years, as evidenced by the evaluation of the potential antimicrobial activities of quinones. Among fungi of medical interest, yeasts of the genus Candida are of extreme importance due to their high frequency of colonization and infection in humans. The objective of this review is to describe the development of naphthoquinones as antifungals for the treatment of Candida species and to note the most promising compounds. By using certain criteria for selection of publications, 68 reports involving both synthetic and natural naphthoquinones are discussed. The activities of a large number of substances were evaluated against Candida albicans as well as against 7 other species of the genus Candida. The results discussed in this review allowed the identification of 30 naphthoquinones with higher antifungal activities than those of the currently used drugs.
