Derivatives of the thiazolidine-2,4-dione core represent a heterocyclic class with several correlated properties. In this context, the synthesis of structural analogues of these bioactive substances becomes attractive in the field of medicinal chemistry. These analogues act as antimicrobial agents against Gram-positives pathogens. The present work aimed to synthesize 10 different derivatives of 5-arylidene-thiazolidine-2,4-dione, employing urea as the catalyst in a solvent-free reaction medium, with yields that ranged from 45 to 99percent. The compounds obtained were submitted to an antimicrobial assay against S. aureus ATCC 29213. Two compounds presented minimum inhibitory concentration of 62.5 and 32.5 μg mL-1 and minimum bactericidal concentration -1, demonstrating their antibacterial potential. Principal component analysis was carried out to discriminate the compounds in active and inactive classes. Four geometric and electronic molecular descriptors were required to completely discriminate the compounds. The selected descriptors can guide us in designing new 5-arylidene-thiazolidine-2,4-dione derivatives with enhanced activity.

Several findings propose the altered tau protein network as an important target for Alzheimer's disease (AD). Particularly, two points of pharmacological intervention can be envisaged: inhibition of phosphorylating tau kinase GSK-3β and tau aggregation process. On the basis of this consideration and on our interest in multitarget paradigms in AD, we report on the discovery of 2,4-thiazolidinedione derivatives endowed with such a profile. 28 and 30 displayed micromolar IC50 values toward GSK-3β, together with the capacity of inhibiting AcPHF6 aggregation of 60% and 80% at 10 μM, respectively. In addition, they showed PAMPA-BBB permeability, together with a suitable cellular safety profile. 30 also displayed inhibition of both K18 and full-length tau aggregations. Finally, both compounds were able to improve cell viability in an okadaic acid-induced neurodegeneration cell model. To the best of our knowledge, 28 and 30 are the first balanced, nontoxic, dual-acting compounds hitting tau cascade at two different hubs.

Abstract: The present work describes the design, synthesis, molecular docking, biological evaluation, and assessment of structure–activity relationship of new derivatives based upon the molecular skeleton of the drug pioglitazone, a compound which is currently used for the management of type 2 diabetes mellitus. Pioglitazone has several side effects such as weight gain, edema, congestive heart failure, and bladder cancer. Therefore, there is a strong demand for identification of new lead candidates in the treatment of type 2 diabetes mellitus. A series of 24 compounds were prepared and evaluated for their peroxisome proliferator-activated receptor-γ (PPARγ) binding affinity assay and the IC50 values were determined. Among these compounds, six compounds exhibited promising IC50 values as compared to standard drugs pioglitazone and rosiglitazone. Furthermore, in order to confirm the target of these molecules, molecular docking study was carried out with peroxisome proliferator-activated receptor-γ (PPARγ) protein. Molecular modeling studies suggested that these compounds appropriately interact in the active sites of receptor. Graphical abstract: [Figure not available: see fulltext.].

Herein, we describe a one-pot, three-component method for the synthesis of 5-arylidene-4-aminothiazol-2(5H)-ones based on the reaction of isorhodanine, aromatic aldehydes, and ethanolamine. The one-pot procedure for chromeno[2,3-d]thiazol-2-one synthesis starting from 4-aminothiazol-2(5H)-one was proposed following the study of 5-(2-hydroxybenzylidene)-thiazolidinones. Structural features of the starting 4-thioxo-2-thiazolidinone, 4-aminothiazol-2(5H)-one, and target compounds are discussed.
