Crystal structures of two thiazolidinone derivatives bearing a trichloromethyl substituent at the 2-position

The title compounds 2-trichloromethyl-3-phenyl-1,3-thiazolidin-4-one (C10H8Cl3NOS), 1 and 3-(4-chlorophenyl)-2-trichloromethyl-1,3-thiazolidin-4-one (C10H7Cl4NOS) 2, are structurally related with one atom substitution difference in the para position of the benzene ring. In both structures, the thiazolidinone ring adopts an envelope conformation with the S atom as the flap. The dihedral angles between the rings [48.72 (11) in 1 and 48.42 (9)degrees in 2] are very similar and the molecules are almost superimposable. In both crystal structures, C-H center dot center dot center dot O ‘head-to-tail’ interactions between the chiral carbon atoms and the thiazolidinone oxygen atoms result in infinite monochiral chains along the direction of the shortest unit-cell parameter, namely a in 1 and b in 2. C-H center dot center dot center dot pi interactions between the thiazolidinone carbon atom at the 4-position and the phenyl ring of the neighboring enantiomer also help to stabilize the packing in each case, although the crystals are not isostructural.

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.

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.

New hydrazide-hydrazones and 1,3-thiazolidin-4-ones with 3-hydroxy-2-naphthoic moiety: Synthesis, in vitro and in vivo studies

In this research we synthesized, identified and evaluated new hydrazide-hydrazones (1-3) and 1,3-thiazolidin-4one derivatives (4-6) for in vitro and in vivo activity. New hydrazide-hydrazones (1-3) were obtained by the condensation reaction of 3-hydroxy-2-naphthoic acid hydrazide with appropriate aldehydes. Synthesized hydrazide-hydrazones (1-3) were subjected to cyclization reaction with mercaptoacetic acid which afforded with new 1,3-thiazolidin-4-one derivatives (4-6). Among 1,3-thiazolidin-4-one derivatives tested (4-6), compound 6 exhibited highest and most selective cytotoxicity towards human renal adenocarcinoma cells (769-P) and it did not affect the growth of normal cells (H9c2, GMK). Whereas its hydrazide-hydrazone (compound 3) showed significant antiproliferative activity against both tested human cancer cell lines: renal adenocarcinoma (769-P) and hepatocellular carcinoma (HepG2), however with less selectivity. The in vivo studies focused on the anti-nociceptive activity of newly synthesized 1,3-thiazolidin-4-one derivatives (4-6). The preliminary screening of novel compounds showed that 1,3-thiazolidin-4-one derivatives (4-6) are safe and not toxic against CNS of mice. Among tested derivatives one compound (6) displayed significant analgesic activity.

Synthesis and Biological Evaluation of New 4-Thiazolidinone Derivatives as Carbonic Anhydrase Inhibitors

Background: The catalytically active site of CA enzyme is Zn (II) bound hydroxide ion part which acts as a strong nucleophile (at neutral pH) on the CO2 molecule bound in a hydrophobic pocket nearby. We designed a series of thiazolidinone molecules which are able to approach the active side by way of hydrophobic part and may interact with the hydroxide and Zn (II) by ring opening of thiazolidinone. Methods: Thirteen novel aminoindane thiazolidinone derivatives, 2a-m were synthesized, characterized and their inhibitory effects on the activity of purified human carbonic anhydrase (hCA) I and II were evaluated. hCA I and II from human erythrocytes were purified by a simple one step procedure by using Sepharose 4B-L-tyrosine-sulphanilamide affinity column. Results: In vitro results showed that all compounds were inhibited by the CA izoenzymes activity. 2d was found to be most active compound IC50=6.75 mu M and 7.55 mu M for hCA I and hCA II, respectively. Conclusion: New aminoindane thiazolidinone derivatives have been designed, synthesized and evaluated as Carbonic Anhydrase Inhibitors. According to the results, these compounds can be conceivable as new candidates for the treatment of the illness that CAI and CAII enzyme inhibitors are used in the treatment.
