Synthesis, DFT Study, and Antitumor Activity of Some New Heterocyclic Compounds Incorporating Isoxazole Moiety

Thiazolidin-4-one derivative 3 was synthesized by the transformation of chloroacetamide derivative 2 with NH4SCN. The condensation of 3 with p-anisaldehyde afforded the corresponding arylidene derivative 4. Also, the alkylation of chloroacetamide derivative 2 with different heterocyclic compounds was investigated. Annulation of 5-amino-3-methylisoxazole (1) with alpha-halocarbonyl compounds 12 and 14 furnished pyrrolo[3,2-d]isoxazole and isoxazolo[5,4-b]azepin-6-one derivatives 13 and 15, respectively, while reaction of 1 with 1-chloro-4-(chloromethyl)benzene gave the monoalkylated product 17. The newly synthesized compounds were screened for their antitumor activity, and the geometry optimizations are in a good agreement with the experimentally observed data.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 29681-57-0 is helpful to your research. Category: thiazolidines.

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.

Chiral syntheses of methyl (R)-2-Sulfanylcarboxylic esters and acids with optical purity determination using HPLC

Accessible chiral syntheses of 3 types of (R)-2-sulfanylcarboxylic esters and acids were performed: (R)-2-sulfanylpropanoic (thiolactic) ester (53%, 98%ee) and acid (39%, 96%ee), (R)-2-sulfanylsucciinic diester (59%, 96%ee), and (R)-2-mandelic ester (78%, 90%ee) and acid (59%, 96%ee). The present practical and robust method involves (i) clean S(N)2 displacement of methanesulfonates of (S)-2-hydroxyesters by using commercially available AcSK with tris(2-[2-methoxyethoxy])ethylamine and (ii) sufficiently mild deacetylation. The optical purity was determined by the corresponding (2R,5R)-trans-thiazolidin-4-one and (2S,5R)-cis-thiazolidin-4-one derivatives based on accurate high-performance liquid chromatography analysis with high-resolution efficiency. Compared with the reported method utilizing AcSCs (generated from AcSH and CsCO3), the present method has several advantages, that is, the use of odorless AcCOSK reagent, reasonable reaction velocity, isolation procedure, and accurate, reliable optical purity determination. The use of accessible AcSK has advantages because of easy-to-handle odorless and hygroscopic solid that can be used in a bench-top procedure. The Ti(OiPr)(4) catalyst promoted smooth trans-cyclo-condensation to afford (2R,5R)-trans-thiazolidin-4-one formation of (R)-2-sulfanylcarboxylic esters with available N-(benzylidene)methylamine under neutral conditions without any racemization, whereas (2S,5R)-cis-thiazollidin-4-ones were obtained via cis-cyclo-condensation and no catalysts. Direct high-performance liquid chromatography analysis of methyl (R)-mandelate was also performed; however, the resolution efficiency was inferior to that of the thaizolidin-4-one derivatizations.

In this study, we described the synthesis of the derivatives of thiosemicarbazide, dicarboximide, 1,2,4-triazole-5-thione and 4-oxo-1,3-thiazolidine. Two different dicarboxylic acid anhydrides reacted with 4-substituted-3-thiosemicarbazide, and derivatives of thiosemicarbazide and dicarboximide were obtained. Next, cyclization reaction of dicarboximide derivatives in alkaline media was used to prepare 1,2,4-triazole-5-thione. The 4-oxo-1,3-thiazolidine was synthesized by the reaction of dicarboximide with ethyl bromoacetate. All obtained derivatives were analysed by H-1 and C-13 NMR spectra, and for one compound, the X-ray crystallography was done. Antimicrobial, antiviral and in vitro evaluations of cytotoxicity were examined. According to the preliminary antiviral screening, compounds 3 and 4 presented the antiviral activity against HSV-1 and CVB3. Additionally, compound 3 shows selective in vitro toxic effect against human epithelial cells FaDu, without affecting normal animal cell line (Vero).

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).

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.
