A series of four compounds which contain thiazolidine-4-one ring were synthesized and preliminarily assessed as anti-inflammatory agents with anticipated selectivity against COX-2 enzyme. The synthesized compounds structures have been recognised according to their spectral FT-IR and 1H NMR data. GOLD software was used to perform molecular docking study. The crystallographic structure of the molecular target cyclo-oxygenase enzyme-2 (COX-2) was taken from PDB database however, the celecoxib and naproxen were selected as a positive controls. The docking results of the newly synthesized compounds shown that they can enter the substrate-binding area of the active site .The compound (Ia) showed the highest PLP fitness,while compound (Ic) appeared to have the lowest binding ability compared to celecoxib which may be due to the presence of para nitro group that deactivates the ring system. Whereas In vivo acute anti-inflammatory effects of the synthesized compounds were evaluated in rats using egg-white induced edema model of inflammation. The tested compounds and the reference drug produced significant decrease in the paw edema with respect to the effect of propylene glycol 50%v/v (control group). Compounds Ia,b,d showed potent anti-inflammatory effect than naproxen (50mg/kg, i.p.) at 180 min., while compound Ic exhibited lower anti-inflammatory effect.

A convergent stereoselective synthesis of the potent anti-inflammatory, proresolving and neuroprotective lipid mediator protectin D1 (2) has been achieved in 15% yield over eight steps. The key features were a stereocontrolled Evans-aldol reaction with Nagao’s chiral auxiliary and a highly selective Lindlar reduction of internal alkyne 23, allowing the sensitive conjugated E,E,Z-triene to be introduced late in the preparation of 2. The UV and LC/MS-MS data of synthetic protectin D1 (2) matched those obtained from endogenously produced material.

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.

Research speed reading in 2021. Recommanded Product: Thiazolidin-2-one, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. In a document type is Article, and a compound is mentioned, 2682-49-7, Thiazolidin-2-one, introducing its new discovery.

Eight novel bioactive azo dyes containing thiazolidinone (TZD) derivatives (1O-4S) were designed and synthesized for antibacterial assays and colorimetric sensing of anions. Synthesized compounds were evaluated for their antibacterial activities using the disc diffusion technique. Majority of the compounds showed potent antibacterial activities against the tested bacterial strains in the zone assay. Moderate antibacterial activities were also exhibited in the minimum inhibitory concentration (MIC) assay. In addition, the synthesized compounds were evaluated for their colorimetric sensing of anions. In contrast to dyes with electron donating groups (EDGs), 4O having electron withdrawing groups (EWGs) showed highly selective colorimetric sensing of CN- ions. Binding interaction of 4O with CN- ions provides a remarkable colorimetric response from yellow to blue (Deltalambda = 186 nm), enabling naked-eye sensing without any spectroscopic instrumentation. Furthermore, the limit of detection (LOD) for 4O towards CN- was found to be 0.74 muM.

Herein we report the design, synthesis, molecular docking study and evaluation of antimicrobial activity of ten new dithioloquinolinethiones. The structures of compounds were confirmed by 1H NMR, 13C NMR and HPLC-HRMS. Before evaluation of their possible antimicrobial activity prediction of toxicity was performed. All compounds showed antibacterial activity against eight Gram positive and Gram negative bacterial species. All compounds appeared to be more active than ampicillin and almost all than streptomycin. The best antibacterial activity was observed for compound 8c 4,4,8-trimethyl-5-{[(4-phenyl-5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)thio]acetyl}-4,5-dihydro-1H-[1,2]dithiolo[3,4c]quino lone-1-thione). The most sensitive bacterium En.cloacae followed by S. aureus, while L.monocytogenes was the most resistant. All compounds were tested for antifungal activity also against eight fungal species. The best activity was expressed by compound 8d (5-[(4,5-Dihydro-1,3-thiazol-2-ylthio)acetyl]-4,4-dimethyl-4,5-dihydro-1H-[1,2]dithiolo[3,4-c]quinoline-1-thione). The most sensitive fungal was T. viride, while P. verrucosum var. cyclopium was the most resistant one. All compounds were more potent as antifungal agent than reference compound bifonazole and ketoconazole. The docking studies indicated a probable involvement of E. coli DNA GyrB inhibition in the anti-bacterial mechanism, while CYP51ca inhibition is probably responsible for antifungal activity of tested compounds. It is interesting to mention that docking results coincides with experimental.
