2-Aryl-3-(2-morpholinoethyl)thiazolidin-4-ones: Synthesis, anti-inflammatory in vivo, cytotoxicity in vitro and molecular docking studies

Seven new 4-thiazolidinones bearing the morpholino moiety were easily synthesized by one-pot reactions of 4-(2-aminoethyl)morpholine (2-morpholinoethylamine), arenealdehydes and mercaptoacetic acid refluxing toluene for 19 h with moderate to good yields (45-97%). These novel compounds were fully identified and characterized by NMR spectroscopy and mass spectrometry. Thiazolidin-4-ones in vivo anti-inflammatory activities were determined using a croton oil-induced ear edema model of inflammation in BALB C mice. The best results were found for compounds 4c (49.20 mmol/kg), 4d (49.20 mmol/kg) and 4f (52.48 mmol/kg), which showed the ability to decrease the ear edema in mice by 50%, 48% and 54%, respectively, when compared to the standard drug indomethacin. In addition, the in vitro cytotoxicity activity of thiazolidin-4-ones against Vero cells was also performed and four compounds (4a, 4c, 4d and 4f) showed no toxic effect at 500 mu g/mL. A docking simulation of compounds into the 1Q4G (COX-1) and 4PH9 (COX-2) enzymes binding site was conducted. This preliminary result will guide us in for further studies to improve the anti-inflammatory activity. (C) 2016 Elsevier Masson SAS. All rights reserved.

Molecular docking, design, synthesis and biological evaluation of novel 2,3-aryl-thiazolidin-4-ones as potent NNRTIs

Nonnucleoside reverse transcriptase inhibitors (NNRTIs) remain the most promising anti-AIDS agents that target the HIV-1 reverse transcriptase enzyme (RT). However, the efficiency of approved NNRTI drugs has decreased by the appearance of drug-resistant viruses and side effects upon long-term usage. Thus, there is an urgent need for developing new, potent NNRTIs with broad spectrum against HIV-1 virus and with improved properties. In this study, a series of thiazolidinone derivatives was designed based on a butterfly mimicking scaffold consisting of a substituted benzothiazolyl moiety connected with a substituted phenyl ring via a thiazolidinone moiety. The most promising derivatives were selected using molecular docking analysis and PASS prediction program, synthesized and evaluated for HIV-1 RT inhibition. Five out of fifteen tested compounds exhibited good inhibitory action. It was observed that the presence of Cl or CN substituents at the position 6 of the benzothiazole ring in combination with two fluoro atoms at the ortho-positions or a hydrogen acceptor substituent at the 4-position of the phenyl ring are favourable for the HIV RT inhibitory activity.

Anti-Candida activity and cytotoxicity of a large library of new N-substituted-1,3-thiazolidin-4-one derivatives

On the basis of the recent findings about the biological properties of thiazolidinones and taking into account the encouraging results about the antifungal activity of some (thiazol-2-yl)hydrazines, new N-substituted heterocyclic derivatives were designed combining the thiazolidinone nucleus with the hydrazonic portion. In details, 1,3-thiazolidin-4-ones bearing (cyclo)aliphatic or (hetero)aromatic moieties linked to the N1-hydrazine at C2 were synthesized and classified into three series according to the aromatic or bicyclic rings connected to the lactam nitrogen of the thiazolidinone. These molecules were assayed for their anti-Candida effects in reference to the biological activity of the conventional topic (clotrimazole, miconazole, tioconazole) and systemic drugs (fluconazole, ketoconazole, amphotericin B). Finally, we investigated the selectivity against fungal cells by testing the compounds endowed with the best MICs on Hep2 cells in order to assess their cell toxicity (CC50) and we noticed that two derivatives were less cytotoxic than the reference drug clotrimazole. Moreover, a preliminary molecular modelling approach has been performed against lanosterol 14-alpha demethylase (CYP51A1) to rationalize the activity of the tested compounds and to specify the target protein or enzyme.

In Vitro Effects of 2-{4-[Methylthio(methylsulfonyl)]phenyl}-3-substitutedthiazolidin-4-ones on the Acetylcholinesterase Activity in Rat Brain and Lymphocytes: Isoform Selectivity, Kinetic Analysis, and Molecular Docking

This work evaluated the in vitro effect of thiazolidin-4-ones on the activity of AChE (total and isoforms) isolated from the cerebral cortex, hippocampus, and lymphocytes. Kinetic parameters were evaluated and molecular docking was performed. Our results showed that thiazolidinones derived from 4-(methylthio)benzaldehyde (1) and from 4-(methylsulfonyl)benzaldehyde (2) were capable of inhibiting the AChE activity in vitro. Three compounds, two with a propylpiperidine (1b and 2b) moiety and one with a 3-(diethylamino)propyl (1c) moiety showed IC50 values of 13.81 mu M, and 3.13 mu M (1b), 55.36 mu M and 44.33 mu M (1c) for cerebral cortex and hippocampus, respectively, and 3.11 mu M for both (2b). Enzyme kinetics revealed that the type of AChE inhibition was mixed. Compound 1b inhibited the G1 and G4 AChE isoforms, while compounds 1c and 2b selectively inhibited the G4 isoform. Molecular docking showed a possible three-dimensional fit into the enzyme. Our findings showed that these thiazolidin-4-ones, especially those containing the propylpiperidine core, have a potential cholinesterase inhibitory activity and can be considered good candidates for future Alzheimer’s therapy.

Design, Synthesis, Molecular Docking of Novel Substituted Pyrimidinone Derivatives as Anticancer Agents

Novel derivatives of pyrimidinone ring carrying some five-membered heterocycles had been designed and prepared. 1,3-Thiazolidin-4-one derivative 7 was prepared by the reaction of 1,2,3,4-tetrahydro-4-(4-hydroxyphenyl)-6-methyl-N ‘-((naphthalen-4-yl)methylene)-2-oxopyrimidine-5-carbohydrazide 6 with thioglycolic acid. Reacting the hydrazide 5 with benzoyl chloride gave compound 8 which cyclized to 1,3,4-oxadiazole 9 by the use of phosphorus pentoxide. Moreover, the pyrazole derivative 10 was obtained from reacting compound 5 with ethyl acetoacetate. Furthermore, the reaction of the hydrazide 5 with phenyl isothiocyanates produced the carbothioamide 11 which refluxed with hydrazonoyl chloride to yield 1,3,4-thiadiazole derivative 14. In addition, 1, 2,4-triazole derivative 16 was prepared via reacting the carbothioamide 11 with sodium hydroxide followed by methylation with methyl iodide. The structures of the newly prepared heterocyclic compounds were determined by spectral and elemental analysis. The cytotoxic activity of the target compounds (7, 9, 10, 14, and 16) were estimated in vitro against PC-3 (prostate adenocarcinoma), human HepG-2 (liver carcinoma), and HCT116 (colorectal carcinoma) cell lines using MTT assay. All the tested compounds appeared high level of inhibition against PC-3 and HCT116 cell lines, while appeared weak inhibitory action against HepG-2 cell lines, especially, the thiadiazole derivative 14. Furthermore, docking study had been carried out on the targets 7, 9, 10, 14, and 16 within EGFR as a prediction for the anticancer activity. All the docked compounds showed good fitting with EGFR recording docking scores range (-27.99 to -19.01).
