The Effects of a 5-Chromene-yl-thiazolidin-2,4-dione Derivative in Alleviating Oxidative Stress in Adjuvant-Induced Arthritis

Rheumatoid arthritis (RA) is a chronic inflammatory disease that reduces life quality and requires long-life therapy. Quercetin (Que) is a natural flavonoid with antioxidant and anti-inflammatory effects. (3-(2-(4-Chlorophenyl)-2-oxoethyl)-5-((6-methyl-4-oxo-4H-chromen-3-yl)methylene) thiazolidine-2,4-dione (TZD) is a thiazolidinedione derivative synthesized in our laboratory. This study was designed to investigate the antioxidant effects of the Que and TZD derivative administration in adjuvant-induced arthritic (AIA) rats. AIA was induced in Wistar rats by the intraplantar injection of Freund’s complete adjuvant (FCA), unilaterally in the right hind paw. The control non-arthritic rats and the arthritic rats were treated with Que (30 mg/kg/day) or TZD derivative (12 mg/kg/day) for 21 days. The antioxidant effects of 5-chromen-yl-thiazolidinedione were compared to Que. The serum levels of malondialdehyde (MDA) and protein carbonyl (PC) groups, the superoxide dismutase (SOD) and catalase (CAT) activity were assessed. AIA rats showed significatly increased oxidative stress parameter levels in the blood. The results indicated that the TZD derivative decreased the blood oxidative stress parameters in the treated arthritic rats, compared to Que. The antioxidant effects of 5-chromen-yl-thiazolidinedione in AIA suggest its therapeutic properties for the clinical treatment of RA.

Crystal structures of 3-(2H-1,3-benzodioxol-5-ylmethyl)-2-(m- and p-nitrophenyl)-1,3-thiazolidin-4-ones: different roles of the oxygen atoms

The crystal structures of two isomeric 3-(2H-1,3-benzodioxol-5-ylmethyl)-2-(aryl)-1,3-thiazolidin-4-one compounds (1: aryl=4-O2NC6H4; 2: aryl=3-O2NC6H4) are reported. In both these nonplanar, compounds, the carbonyl oxygen is involved in intramolecular C-H center dot center dot center dot O hydrogen bonds. However, there are significant differences in the sets of intermolecular interactions, in particular the roles of the oxygen atoms, exhibited by the two compounds. Thus in 1, a dioxolyl oxygen and the two nitro group oxygen atoms are each involved in different chain forming C-H center dot center dot center dot O intermolecular hydrogen bonds, while the carbonyl oxygen atom is not involved in any intermolecular interaction. In 2, the dioxolyl oxygen atom is involved in the formation of centrosymmetric dimers, the carbonyl oxygen in three different C-H center dot center dot center dot O hydrogen bonds and the nitro group oxygens in two N-O center dot center dot center dot pi(aryl) interactions. Compound 2 exhibits also C-H center dot center dot center dot pi(phenyl), pi(phenyl)center dot center dot center dot pi(phenyl) and p(benzodioxolyl)center dot center dot center dot pi(benzodioxolyl) interactions, while in 1 only the latter interaction is present. Compound 1 crystallizes in the monoclinic space group, P2(1)/a with Z = 4, while compound 2 crystallizes in the triclinic space group, P (1) over bar, with Z = 2.

An efficient synthesis of designed 4-thiazolidinone fused pyrimidine derivatives as potent antimicrobial agents

A novel series of hybrid 2-substituted ((pyrimidin-2-yl)hydrazinyl)thiazolidin-4-one derivatives were synthesized by means of aromatic nucleophilic displacement of chlorine atoms of 2,4,6-trichloro pyrimidine. Synthesis of some novel 2-(2-(6-morpholino-4-substituted(phenyl amino)pyrimidin-2-yl)hydrazinyl)thiazol-4(5H)-one derivatives have been carried out by the displacement of chlorine atoms on the basis of functionality concept on varying conditions. The synthesized hydrazinyl thiazolidin-4-one pyrimidine derivatives were evaluated for their expected antimicrobialactivity; where, the majority of these compounds showed potent antibacterial and antifungal activities against the tested strains of bacteria and fungi. Afforded title analogs were subsequently characterized by elemental analysis, IR,H-1 NMR,C-13 NMR, Mass spectroscopy. SAR and HOMO-LUMO studies were also carried out for confirming the structure biological activity. Thus, these studies suggested that hydrazinyl pyrimidine derivatives bearing thiazolidinone moiety are interesting scaffolds for the development of novel antimicrobial agents.

Identification of novel quinoline analogues bearing thiazolidinones as potent kinase inhibitors for the treatment of colorectal cancer

In this investigation, a novel series of quinoline analogues bearing thiazolidinones were designed and synthesized based on our previous study. Among them, the most potent compound 11k, 4-((4-(4-(3-(2-(2,6-difluorophenyl)-4-oxothiazolidin-3-yl)ureido)phenoxy)-6-methoxyquinolin-7-yl)oxy)-N-iso-propylpiperidine-1-carboxamide, possessed submicromolar c-Met and Ron inhibitory activities. In addition, enzymatic assays against a mini-panel of kinases (c-Kit, B-Raf, c-Src, IGF1R, PDGFR alpha and AXL) were performed, the results showed that compound 11k exhibited moderate inhibitory activity against PDGFR alpha, c-Src and AXL. MTT assay revealed in vitro antitumor activities against HT-29 cells of compound 11k with an IC50 value of 0.31 mu M which was 9.3- and 34.2-fold more potent than that of Regorafenib (IC50 = 2.87 mu M) and Cabozantinib (IC50 = 10.6 mu M). Preliminary antitumor mechanisms were also investigated by cellular assays. Considerable cytotoxicity, antiproliferation and induction of apoptosis of compound 11k in a dose- and time-dependent manner were confirmed by IncuCyte live-cell imaging assays. Treatment with compound 11k caused slight G2-or M-phase arrest in HT-29 cells. Further cell selectivity of compound 11k showed that it was not active against human normal colorectal mucosa epithelial cell FHC at 10.0 mu g/mL. The above results support further structural modification of compound 11k to improve its inhibitory activity, which will lead to more potent anticancer agents. (C) 2020 Elsevier Masson SAS.

Design, synthesis, and anticancer activity of novel 4-thiazolidinone-phenylaminopyrimidine hybrids

4-Thiazolidinones and phenylaminopyrimidines are known as anticancer agents. Imatinib is the pioneer phenylaminopyrimidine derivative kinase inhibitor, which is used for the treatment of chronic myeloid leukemia. With a hybrid approach, a novel series of 5-benzylidene-2-arylimino-4-thiazolidinone derivatives containing phenylaminopyrimidine core were designed, synthesized, and tested for their anticancer activity on K562 (chronic myeloid leukemia), PC3 (prostat cancer), and SHSY-5Y (neuroblastoma) cells. Since superior anticancer activity was observed on K562 cells, further biological studies of selected compounds (8, 15, and 34) were performed on K562 cells. For the synthesis of designed compounds, thiourea compounds were converted to 2-imino-1,3-thiazolidin-4-ones with alpha-chloroacetic acid in the presence of sodium acetate. 5-Benzylidene-2-imino-1,3-thiazolidin-4-one derivatives were obtained by Knoevenagel condensation of 2-imino-1,3-thiazolidin-4-ones with related aldehydes. Compounds 8, 15, and 34 were evaluated for cell viability, apoptosis studies, cell cycle experiments, and DNA damage assays. IC50 values of compounds 8, 15, and 34 were found as 5.26 +/- 1.03, 3.52 +/- 0.91, and 8.16 +/- 1.27 mu M, respectively, in K562 cells. Preferably, these compounds showed less toxicity towards L929 cells compared to imatinib. Furthermore, compounds 8 and 15 significantly induced early and late apoptosis in a time-dependent manner. Compounds 15 and 34 induced cell cycle arrest at G0/G1 phase and compound 8 caused cell cycle arrest at G2/M phase. Based on DNA damage assay, compounds 8 and 15 were found to be more genotoxic than imatinib towards K562 cells. To put more molecular insight, possible Abl inhibition mechanisms of most active compounds were predicted by molecular docking studies. In conclusion, a novel series of 5-benzylidene-2-arylimino-4-thiazolidinone derivatives and their promising anticancer activities were reported herein. [GRAPHICS] .

Synthesis, in-Vitro Cytotoxicity and Antimicrobial Evaluations of Some Novel Thiazole Based Heterocycles

Condensation of rhodanine (1) with pyrazol-3(2H)-one derivatives (2a-f) gave 5-substituted-2-thioxo-1,3-thiazolidin-4-one derivatives (3a-f). Reaction of compound (1) with 2-arylmethylidene-malononitrile (4a-d) yielded the unexpected derivatives (5a-d). The latter compounds were subjected to cyclization reactions with malononitrile under different basic conditions, hydroxylamine hydrochloride and/or thiourea to furnish the fused thiazole derivatives (6a-d) and (8-10a-d). Coupling of (1) with diazotized aromatic amines (11a-c) in pyridine afforded the arylhydrazones (12a-c). Fusion of latter compounds with malononitrile afforded the thiazolopyridazine derivatives (13a-c). The structures of the newly synthesized compounds were elucidated via spectral data and elemental analyses. The in-vitro cytotoxic activity of compounds (3a-f) against the cell line MCF-7 was evaluated. Also, the synthesized products were investigated for their antibacterial and antifungal activities against six standard organisms including the G(+) bacteria, Staphylococcus aureus and Bacillus subtilis, G(-) bacteria, Escherichia coli and Proteus vulgaris in addition to fungi, Candida albicans and Aspergillus flavus.
