Synthesis and In Vitro Anti-Toxoplasma gondii Activity of Novel Thiazolidin-4-one Derivatives

Recent findings on the biological activity of thiazolidin-4-ones and taking into account the lack of effective drugs used in the treatment of toxoplasmosis, their numerous side effects, as well as the problem of drug resistance of parasites prompted us to look for new agents. We designed and synthesized a series of new thiazolidin-4-one derivatives through a two-step reaction between 4-substituted thiosemicarbazides with hydroxybenzaldehydes followed by the treatment with ethyl bromoacetate; maleic anhydride and dimethyl acetylenedicarboxylate afforded target compounds. The thiazolidin-4-one derivatives were used to assess the inhibition of Toxoplasma gondii growth in vitro. All active thiazolidine-4-one derivatives (12 compounds) inhibited T. gondii proliferation in vitro much better than used references drugs both sulfadiazine as well as the synergistic effect of sulfadiazine + trimethoprim (weight ratio 5:1). Most active among them derivatives 94 and 95 showed inhibition of proliferation at about 392-fold better than sulfadiazine and 18-fold better than sulfadiazine with trimethoprim. All active compounds (82-88 and 91-95) against T. gondii represent values from 1.75 to 15.86 (CC30/IC50) lower than no cytotoxic value (CC30).

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 78-39-7, you can contact me at any time and look forward to more communication. SDS of cas: 78-39-7.

Perspective anti-thyroid drug 2-thioxo-5-(3,4,5-trimethoxybenzylidene) thiazolidin-4-one: X-ray and thermogravimetric characterization of two novel molecular adducts, obtained by interaction with I-2

The attention of many researchers has focused on the search of novel, specific thyreostatics and study the mechanism of their interaction with molecular iodine. However, the study of rhodanine derivatives as the potential thyreostatics was not carried out. The reaction product of 2-thioxo-5-(3,4,5-trimethoxybenzylidene) thiazolidin-4-one is presented by two types of adducts – stoichiomorphs: C13H13NO4S2.I-2 and (C13H13NO4S2)(2).I-2 in chloroform and methylene chloride, respectively. According to the single crystal X-ray diffraction method the I1-I2 bond length (2.762 angstrom) is rather elongated with respect to the average distance in gas phase I-I 2.662 angstrom and the S1…I1 distance is shortened 2.905 angstrom (0.875 angstrom less than VdW radii sum) in adduct 1. The iodine molecule in adduct 2 coordinated by two heterocycle molecules forms two contacts: the S (exocyclic) … I – 3.203 angstrom (0.577 less than VdW radii sum) and S (endocyclic) … I – 3.532 angstrom (0.248 less than VdW radii sum), respectively. The results of thermogravimetric analysis have revealed that the product 2 is more stable than product 1 due to each atom of iodine molecule is coordinated by endo and exocyclic sulfur atoms of two heterocycle molecules. The presence of thyreostatic properties is a main starting point in further investigations of rhodanine series as the potential pharmaceuticals. (C) 2018 Elsevier B.V. All rights reserved.

Efficient approach to thiazolidinones via a one-pot three-component reaction involving 2-amino-1-phenylethanone hydrochloride, aldehyde and mercaptoacetic acid

A highly efficient three-component reaction has been developed for the synthesis of thiazolidinones involving the reaction of 2-amino-1-phenylethanone hydrochloride with an aromatic aldehyde and mercaptoacetic acid in the presence of diisopropylethylamine in a single pot. Critically, this reaction exhibited excellent chemoselectivity, with the nitrogen atom of the 2-amino-1-phenylethanone component reacting selectively with the aromatic aldehyde to give the corresponding Schiff base. Nucleophilic attack at the carbon of the Schiff base by the sulfur atom of mercaptoacetic, followed by a cyclocondensation reaction between the nitrogen and the carboxylic acid moiety afforded the desired thiazolidinones, which were fully characterized by spectroscopic techniques.

Crystal structure and Hirshfeld surface analysis of (E)-5-phenyl-3-[(pyridin-4-ylmethylidene)amino]thiazolidin-2-iminium bromide monohydrate

In the cation of the title salt, C15H15N4S+center dot Br-center dot H2O, the central thiazolidine ring adopts an envelope conformation with puckering parameters Q(2) = 0.279 (4) angstrom and phi(2) = 222.5 (9)degrees. The mean plane of the thiazolidine ring makes dihedral angles of 12.4 (2) and 66.8 (3)degrees with the pyridine and phenyl rings, respectively. The pyridine ring in the title molecule is essentially planar (r.m.s deviation = 0.005 angstrom). In the crystal, the cations, anions and water molecules are linked into a three-dimensional network, which forms cross layers parallel to the ((1) over bar 20) and (120) planes via O-H center dot center dot center dot Br, N-H center dot center dot center dot Br and N-H center dot center dot center dot N hydrogen bonds. C-H center dot center dot center dot pi interactions also help in the stabilization of the molecular packing.

Design of a new multi-functional catalytic system Ni/SO3H@zeolite-Y for three-component synthesis of N-benzo-imidazo- or -thiazole-1,3-thiazolidinones

In this investigation, a nanoporous zeolite-NaY supported sulfonic acid was synthesized and Ni(ii) ions were successfully stabilized on SO3H@zeolite-Y (Ni/SO3H@zeolite-Y). This novel type of zeolitic nanocomposite was characterized using various techniques including FT-IR, FE-SEM, TGA, BET and EDX. Ni/SO3H@zeolite-Y was used as a multi-functional and highly active nanocatalyst for the three-component synthesis of 3-benzimidazolyl-1,3-thiazolidin-4-ones and new 3-benzthiazoleyl-1,3-thiazolidin-4-ones via cyclocondensation of 2-aminobenzimidazole or 2-aminobenzothiazole, aromatic aldehydes and thioglycolic acid in acetone-H2O at room temperature. This economical chemical procedure has advantages such as excellent yield in short reaction times, convenient manipulation and high purity of products, applicability to a broad range of substrates, and the use of a nontoxic and heterogeneous acid catalyst with good reusability.

Within the molecule in the crystal structure, the cyclohexene ring has an envelope conformation and the cycloheptane ring, to which it is fused, has a boat conformation. In the crystal, molecules are linked by C-H center dot center dot center dot Cl hydrogen bonds forming chains propagating along the b-axis direction. The absolute configuration of the molecule in the crystal could be fully confirmed from anomalous dispersion effects [Flack parameter = -0.04 (2)]. Thiosemicarbazones 1 and 2 are efficient inhibitors for steel corrosion in 1 M H2SO4 solution, with a maximum efficiency of 92.28% at 10(-3) M. Furthermore, thiosemicarbazone compounds were found to be more efficient than thiazolidin-4-one derivatives.
