Selective cyclooxygenase-2 inhibitors: A review of recent chemical scaffolds with promising anti-inflammatory and COX-2 inhibitory activities

Selective cyclooxygenase-2 (COX-2) inhibitors have exhibited notable medicinal importance. In recent years, the discovery of new anti-inflammatory agents as selective COX-2 inhibitors has acquired more attention. This is due to the fact that currently available COX-2 inhibitors are linked with adverse effects. Various new organic scaffolds are being explored as new COX-2 inhibitors. In this review, we have mainly described different chemical scaffolds which have been investigated for COX-2 inhibition and anti-inflammatory activity. In the current review, literature from the last 10 years has been included. It will be helpful for organic and medicinal chemists to scrutinize new agents with minimum side effects.

New formaldehyde derivatives were prepared in good yields by a short and versatile route. Several crystal structures of corresponding thioacetic acid esters and thiols were determined. The thioacetates were cleaved under acidic or basic conditions affording the thiols in high yield, thus introducing the new substance classes of N-mercaptomethyl-alkylcarboxamides, N-mercapto- methylsulfonamides, and alkoxymethanethiols.

Amongst several communicable diseases (CDs), malaria is one of the deadliest parasitic disease all over the world, particularly in African and Asian countries. To curb this menace, numbers of antimalarial agents are being sold as over the counter (OTC) drugs. Chloroquine (CQ) is one of them and is one of the oldest, cheapest, and easily available synthetic agents used to curb malaria. Unfortunately, after the reports of CQ-resistance against different strains of malarial parasite strains worldwide, scientist are continuously modifying the core structure of CQ to get an efficient drug. Interestingly, several new drugs have been emerged in due course having unique and enhanced properties (like dual stage inhibitors, resistance reversing ability etc.) and are ready to enter into the clinical trial. In this course, some new agents have also been discovered which are; though inactive against CQS strain, highly active against CQR strains. The present article describes the role of modification of the core structure of CQ and its effects on the biological activities. Moreover, the attempt has also been made to predict the future prospects of such drugs to reemerge as antimalarial agents.

Covering: January 2013 to September 2018 Sulfur-containing natural products are a large class of significant functional molecules. Many of these compounds exhibit potent biological activities and pharmacological properties; in fact, some of them have been developed into important drugs. The total synthesis of sulfur-containing natural products is a subject that has long attracted significant attention from synthetic organic chemists; to achieve this goal, various methods have been developed over the past years. This review surveys total syntheses of sulfur-containing natural products that introduce sulfur atoms using different sulfurization agents to construct related sulfur-containing moieties.

2682-49-7, Name is Thiazolidin-2-one, belongs to thiazolidine compound, is a common compound. 2682-49-7In an article, authors is Agerbirk, Niels, once mentioned the new application about 2682-49-7.

Two isomeric phenolic glucosinolates, m- and p-hydroxyl derivatives of epiglucobarbarin [(R)-2-hydroxy-2-phenylethylglucosinolate], co-occur in an eastern chemotype (P-type) of the crucifer Barbarea vulgaris along with epiglucobarbarin itself. Levels of the phenolic derivatives in B. vulgaris were low in summer but higher during fall and winter, allowing isolation of all three glucosinolates. Hydrolysis in vitro, catalyzed by Sinapis alba myrosinase at near neutral pH, resulted in expectable oxazolidine-2-thione type hydrolysis products of epiglucobarbarin and its m-hydroxyl derivative. In contrast, a thiazolidine-2-one type product was formed in vitro from p-hydroxy epiglucobarbarin and characterized by UV, IR, MS/MS and 2D NMR. Maceration of leaf material resulted in disappearance of the glucosinolates and formation of the same oxazolidine-2-thione and thiazolidine-2-one products as found in vitro. The detected amounts were comparable to initial amounts of precursor glucosinolates. The corresponding oxazolidine-2-thione type product was also detected quantitatively from glucobarbarin in foliage of a western genotype (G-type). We suggest that p-hydroxy epiglucobarbarin is initially converted into the conventional oxazolidine-2-thione, which would further rearrange to a thiazolidine-2-one due to the activating effect of the p-hydroxyl group. We conclude that a subtle difference between isomeric phenolic glucosinolates results in significantly different natural hydrolysis products.

Addition of both antipodes of 4-phenyl 1,3-oxazolidine-2-thione to 4-substituted N-crotonyl 1,3-oxazolidin-2-ones furnished Michael addition products. A perfect match occurred when both Michael donor and acceptor possessed the same stereochemistry and a mismatch when they had opposite stereochemistries. The newly created stereochemical center was shown to be governed by the Michael donor and not by the acceptor.

Benzothiazole incorporated thiazolidin-4-ones and azetidin-2-ones derivatives: Synthesis and in vitro antimicrobial evaluation

In this study, a series of novel thiazolidin-4-ones (5a?g) and azetidin-2-ones (6a?g) were synthesized from N-(6-chlorobenzo[d]thiazol-2-yl)hydrazine carboxamide derivatives of the benzothiazole class. Antimicrobial properties of the title compound derivatives were investigated against one Gram (+) bacteria (Staphylococcus aureus), three Gram (?) bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae) and five fungi (Candida albicans, Aspergillus niger, Aspergillus flavus, Monascus purpureus and Penicillium citrinum) using serial plate dilution method. The investigation of antibacterial and antifungal screening data revealed that all the tested compounds showed moderate to good inhibition at 12.5?200?mug/mL in DMSO. It has been observed that azetidin-2-ones derivatives are found to be more active than thiazolidin-4-ones derivatives against all pathogenic bacterial and fungal strains.

One-pot multicomponent approach towards the synthesis of heterocyclic compounds by using beta-cyclodextrin as a catalyst

Background: Heterocyclic compounds have received much attention due to their versatile applications in the field of medicinal chemistry as well as organic chemistry. Objective: The main objective of this review is to give an overview of the recent application of beta-cyclodextrin catalyzed one?pot multicomponent reactions for the synthesis of different assemblies of heterocycles. Method: In this review, we have summarized the one-pot multicomponent approach towards the synthesis of heterocyclic compounds by using beta-cyclodextrin as a supramolecular catalyst. It is outlined under the headings (1) five-membered heterocyclic compounds and (2) six and seven membered heterocyclic compounds. Conclusion: This review outlined the recent key developments in the synthesis of different O-, N-and S-containing heterocyclic scaffolds, following MCRs published by using beta-CD and its derivatives as a supramolecular catalyst for the synthesis of five, six and seven membered heterocycles. The versatility of cyclodextrins and modified cyclodextrins will encourage chemists to develop new heterocyclic molecules by using multicomponent reactions in the near future.
