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.

The complex is formed at pH 5.0 in acetate buffer medium after heating in the boiling water bath (similar to 371 K) for 25 min. The complex has maximum absorption at 350 nm and is stable for 24 h. Beer’s law is valid over the concentration range of 0.5-6.1 mu g mL(-1) for Ru(IV). The molar absorptivity at lambda= 350 nm is 6.21 x 10(3) L mol(-1) cm(-1). The limit of detection of this method is 0.2 mu g mL(-1). The interfering effect of various cations and anions on the spectrophotometric determination of the Ru(IV) were investigated. The proposed method was successfully applied to the determination of Ru(IV) in alloys.

Organocatalytic Enantioselective alpha-Amination of Thiazol-4-one-5-carboxylates with Azodicarboxylates

An effective method for the asymmetric synthesis of 5-hydrazinothiazol-4-one-5-carboxylates was developed. The tetrasubstituted chiral carbon center was generated by asymmetric amination of thiazol-4-one-5-carboxylate with azodicarboxylate catalyzed by a bifunctional squaramide-based (1R,2R)-cyclohexane-1,2-diamine backbone in good to excellent yields (40-96%) with high levels of enantioselectivity (92-98% ee). A representative transformation of the amination product to a biologically important 1,3,4-oxadiazol-2(3H)-one is achieved without any appreciable loss in enantioselectivity. Additionally, upon treatment with NaBH3CN, the amination product could also be converted into a biologically important thiazolidin-4-one derivative in good yield without any loss of stereochemical integrity.

DESIGN, SYNTHESIS AND IN-SILICO STUDY OF NOVEL SERIES OF 2-PHENYL-3-(5-SULFANYL-1,3,4-THIADIAZOL-2-YL)-1,3-THIAZOLIDIN-4-ONE DERIVATIVES WITH POTENTIAL ANTI-TUBERCULAR ACTIVITY

In an attempt to identify potential new agents active against tuberculosis with Shikimate kinase as the target, a novel series of 2-phenyl- 3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one derivatives were synthesized by convenient one-pot three-component reaction of amine, aldehyde and mercaptoacetic acid on montmorillonite KSF clay as a solid acidic catalyst in good yields. The structures of the newly synthesized compounds were confirmed by IR, H-1-NMR and elemental analysis and were subjected for anti-tubercular activity by Microplate Alamar Blue Assay (MABA) against Mycobacterium tuberculosis H37Rv. Docking and ADMET studies were used to better describe the titled compounds as potential anti-tubercular agents. The compound, 2-(3,4-dimethoxyphenyl)-3-(5-sulfanyl-1,3,4-thiadiazol-2-yl)-1,3-thiazolidin-4-one(4j), was found to be the most active against Mycobacterium tuberculosis H37Rv with MIC of 1.6 mu g/ml and good drug likeness and dock scores. Molecular docking study revealed that the molecules fit well into the cavity of Shikimate kinase. Also, the molecular properties and bioactivity scores for the synthesized compounds obtained by in-silico studies were found to be within the acceptable range defined for human use revealing their potential as possible drug-like compounds. The anti-tubercular activity of the titled compounds was comparable to that of the standard drug Isoniazid and Ciprofloxacin. The results indicate that the synthesized thiadiazolyl-thiazolidinone derivatives may have an affinity towards Shikimate kinase active site which can be further explored for selective target based studies. Thus these compounds could act as a potential lead for further anti-tubercular studies.
