Diastereoselective construction of syn-alpha-oxyamines via three-component alpha-oxyaldehyde-dibenzylamine-alkyne coupling reaction: application in the synthesis of (+)-beta-conhydrine and its analogues

A Cu(I)-catalyzed alpha-oxyaldehyde-dibenzylamine-alkyne coupling reaction was delineated for the construction of alpha-oxyamines with excellent yields and diastereoselectivity. Crystal structure analysis and theoretical calculations were also supportive of the formation of syn-alpha-oxyamines as the major products. Application of the methodology addresses the synthesis of (+)-beta-conhydrine along with analogs having two different diversity features. A ring size variation allows construction of piperidine and pyrrolidine rings while a variation of side arm functionality is achieved by complete regioselective opening of epoxide by different organocopper ylides (Gilman reagents). A lactam-Cu(I) complexation motif is proposed which allows an intramolecular attack of ylides at the terminal epoxy carbon via the six-membered cyclic transition state. The present work features the synthesis of (+)-beta-conhydrine over eight steps in 26% yield and its seven analogs in 21-28% yields.

The safener effect of chiral derivatives of 3-dichloroacetyl oxazolidine against haloxyfop-P-methyl-induced toxicity in maize

Herbicide safener, a diverse group of chemicals, is an important tool used to protect plants from herbicidal injury. With the aim of decreasing drift injury of haloxyfop-P-methyl to sensitive plants, the protective effect of four safeners (R-28725, 3-dichloroacetyl oxazolidine and its two optical isomers) was evaluated. Physiological and biochemical tests were conducted under laboratory conditions in Northeast Agricultural University, China, by using seed treatment with safener and soil treatment with haloxyfop-P-methyl, respectively. The maize seeds treated with these safeners were safe from haloxyfop-P-methyl treatment. A positive correlation between growth level and endogenous glutathione (GSH) content, glutathione S-transferases (GST) activity was observed in this research. Enhancement of GSH content, GST activity and affinity of GST to 1-chloro-2,4-dinitrobenzene (CDNB) in maize treated by R-28725 was maximum. However, the detoxification of herbicide was not accompanied by the increase of acetyl-CoA-carboxylase (ACC) activity in maize.

Toward a treatment of diabesity: Rational design, synthesis and biological evaluation of benzene-sulfonamide derivatives as a new class of PTP-1B inhibitors

Targeting of protein tyrosine phosphatase-1B (PTP1B) has emerged as a promising strategy for therapeutic intervention of diabetes and obesity. Investigation of new inhibitors with good bioavailability and high selectivity is the major challenge of drug discovery program targeting PTP1B. Therefore, herein, new neutral benzenesulfonamide containing compounds were designed, synthesized and biologically evaluated as potent PTP1B inhibitors. New series of thiazolidine, oxazolidine, thiazinan, oxazinan, oxazole, thiazole, tetrazole, cyanopyridine, chromenone, and iminochromene of benzene-sulfonamide derivatives (MSE-1 to MSE-15) were synthesized in a good yield under mild condition using sulfadiazine as a starting material. Among the synthesized compounds, MSE-13 and MSE-14 showed the most in vitro potent PTP-1B inhibitory activity (IC50 of 0.88 mu M and 3.33 mu M, respectively). Animal treatment by the target compounds significantly improved the insulin resistance, diminished plasma glucose level, decreased initial body weight, and normalized the serum lipid profile compared to pioglitazone, a standard PTP1B inhibitor. The molecular modeling study showed a high affinity and selectivity of our synthesized compounds to the active site and B-site of PTP1B holding hydrogen bonding, hydrophobic, and electrostatic interactions. Furthermore, Electrostatic Surface Potential (ESP) and HOMO/LUMO analysis indicated the importance of sulfamoyl moiety for PTP1B binding. In silico ADME predictions of such compounds also showed the promising pharmacokinetic and physicochemical properties. The proposed compounds could be considered a lead inhibitory scaffold to PTP1B.

Microwave-Assisted Improved Synthesis of Oxazolidin-2-ones, Oxazolidine-2-thiones and Thiazolidine-2-thione Chiral Auxiliaries

A microwave assisted method for the synthesis of some typical 4-substituted oxazolidinone chiral auxiliaries used in asymmetric synthesis is reported in this work. Under these conditions, treatment of (S)-phenylalaninol, (S)-phenylglycinol, (S)-valinol and (1S, 2R)-norephedrine with ethyl carbonate or carbon disulfide under the appropriate and specific microwave reaction conditions, led to an efficient synthesis of some oxazolidin-2-ones, oxazolidine-2-thiones and thiazolidine-2-thiones. The methodology reported in this paper provides these chiral auxiliaries with improved yields and a remarkable reduction on the reaction times, particularly in the case of thiazolidine-2thiones, as compared with the conventional methods. All the auxiliaries prepared here show spectroscopic data in full agreement with those previously reported in the literature.

Development of a theoretical model for the inhibition of nsP3 protease of Chikungunya virus using pyranooxazoles

Chikungunya virus (CHIKV) causes Chikungunya fever (CHIKF) and till date no effective medicine for its cure is available in market. Different research groups find various possible interactions between small molecules and non-structural proteins, viz. nsP3, one of the most important viral elements in CHIKV. In this work, authors have studied the interactions of nsP3 protease of CHIKV with pyranooxazoles. Initially, a one-pot three-component reaction was designed using oxazolidine-2,4-dione, benzaldehyde and cyanoethylacetate to get a proposed biological active molecule, i.e. based on pyranooxazoles. The mechanism for the synthesis of the product based on pyranooxazole was studied through density functional theory (DFT) using Gaussian. Then, a library of the obtained pyranooxazole was created through computational tools by varying the substituents. Further, virtual screening of the designed library of pyranooxazoles (200 compounds) against nsP3 protease of CHIKV was performed. Herein, CMPD 104 showed strongest binding affinity toward the targeted nsP3 protease of CHIKV, based on the least binding energy obtained from docking. Based on docking results, the pharmacological, toxicity, biological score and Lipinski’s filters were studied. Further, DFT studies of top five compounds were done using Gaussian. Molecular dynamics (MD) simulation of nsP3 protease of CHIKV with and without 104 was performed using AMBER18 utilizing ff14SB force field in three steps (minimization, equilibration and production). This work is emphasized to designing of one-pot three-component synthesis and to develop a theoretical model to inhibit the nsP3 protease of CHIKV.

Stereoselective Synthesis and Antiproliferative Activity of Steviol-Based Diterpen Aminodiols

A library of steviol-based trifunctional chiral ligands was developed from commercially available natural stevisoide and applied as chiral catalysts in the addition of diethylzinc to benzaldehyde. The key intermediate steviol methyl ester was prepared according to literature procedure. Depending on the epoxidation process, both cis- and trans-epoxyalcohols were obtained. Subsequent oxirane ring opening with primary and secondary amines afforded 3-amino-1,2-diols. The ring opening with sodium azide followed by a click reaction with alkynes resulted in dihydroxytriazoles. The regioselective ring closure of N-substituted aminodiols with formaldehyde was also investigated. The resulting steviol-type aminodiols were tested against a panel of human adherent cancer cell lines (A2780, SiHa, HeLa, and MDA-MB-231). It was consistently found that the N-benzyl substituent is an essential part within the molecule and the ring closure towards N-benzyl substituted oxazolidine ring system increased the antiproliferative activity to a level comparable with that of cisplatine. In addition, structure-activity relationships were examined by assessing substituent effects on the aminodiol systems.

Asymmetric tandem conjugate addition-protonation to forge chiral secondary C-O bonds for quaternary carbon stereocenters at the nonadjacent beta-position

A direct strategy to construct chiral secondary C-O bonds for quaternary carbon stereocenters at the nonadjacent beta-position is described. Methylene 1,3-oxazolidine-2,4-diones were for the first time employed in an asymmetric reaction as viable electrophiles undergoing a tandem conjugate addition-protonation process. Using an L-amino acid-based urea-tertiary amine catalyst, the reaction with 3-substituted oxindoles gave valuable protonation adducts featuring 1,3-quaternary-tertiary (C-O) nonadjacent stereocenters in high yields and excellent stereoselectivities. The method was successfully extended to sulphur nucleophiles for synthesizing chiral 1,3-sulfur-tertiary alcohol derivatives with bioactive importance.

Visualization of Penetration and Reaction of Aldehyde Tanning Agent in Leather using Fluorescence Technique

Penetration and reaction of tanning agents in leather greatly influence tanning performance and leather quality. Aldehyde tanning agents are widely used in leather manufacture, but their penetration and reaction in leather cannot be detected easily. Considering the fact that aldehyde can form a fluorescent Schiff base with amino groups of collagen, we visualized the distribution and reactivity of typical aldehyde tanning agents in leather during tanning process using a fluorescence microscope. The results showed that glutaraldehyde in leather was easily observed under the fluorescein isothiocyanate (FITC) filter system. The fluorescence intensity of pelt/leather gradually increased with penetrating of glutaraldehyde, basifying and heating, which was consistent with the formation of Schiff base and the increase in T-s of pelt/leather. Oxidized sodium alginate and dialdehyde sodium carboxymethyl cellulose in leathers were also detected using a fluorescence microscope because the aldehyde group of the two tanning agents formed a fluorescent Schiff base with amino groups of collagen. The oxazolidine tanned leather and the tetrakis hydroxymethyl phosphonium tanned leather emitted little fluorescence because they crosslinked collagen with hydroxymethyl group. These results indicate the fluorescent technique is useful to visualize the penetration and reaction of aldehyde tanning agents that crosslink collagen with aldehyde groups.
