This paper report is an analysis of the title compound by means of X-ray crystallography, FT-IR, NMR and DFT calculations, in the context of structural and spectral characterization. The crystal and molecular structures of the compound were determined by single-crystal X-ray diffraction (SCXRD). Fourier Transform Infrared (FTIR) spectrum was recorded in the range from 400 cm(-1) to 4000 cm(-1). The H-1 and C-13 nuclear magnetic resonance (NMR) spectra were also recorded. DFT calculations were employed to support X-ray molecular geometry and calculate IR and NMR (H-1 and C-13) spectral bands. The structural (bond lengths, bond angles, torsion angles) and spectral (vibrational modes and chemical shifts) parameters obtained from DFT levels (B3LYP/6-31G(d,p) and B3LYP/6-31G+(d,p)) were compared with experimental findings, and an excellent harmony between the two data was ascertained.

1,3-Thiazolidin-4-ones: Biological Potential, History, Synthetic Development and Green Methodologies

Background: We present here the synthesis of 1,3-thiazolidin-4-one (1) and its functionalised analogues, such as the classical isosteres, glitazone (1,3-thiazolidine-2,4-dione) (2), rhodanine (2-thioxo-1,3-thiazolidin-4-one) (3) and pseudothiohydantoin (2-imino-1,3-thiazolidin-4-one) (4) started in the mid-nineteenth century to the present day (1865-2018). The review focuses on the differences in the representation of the molecular structures discussed here over time since the first discussions about the structural theory by Kekule, Couper and Butlerov. Moreover, advanced synthesis methodologies have been developed for obtaining these functional group, including green chemistry. We discuss about its structure and stability and we show the great biological potential. Conclusion: The 1,3-thiazolidin-4-one nucleus and functionalised analogues such as glitazones (1,3-thiazolidine-2,4-diones), rhodanines (2-thioxo-1,3-thiazolidin-4-ones) and pseudothiohydantoins (2-imino-1,3-thiazolidine-2-4-ones) have great pharmacological importance, and they are already found in commercial pharmaceuticals. Studies indicate a promising future in the area of medicinal chemistry with potential activities against different diseases. The synthesis of these nuclei started in the mid-nineteenth century (1865), with the first discussions about the structural theory by Kekule, Couper and Butlerov. The present study has demonstrated the differences in the representations of the molecular structures discussed here over time. Since then, various synthetic methodologies have been developed for obtaining these nuclei, and several studies on their structural and biological properties have been performed. Different studies with regards to the green synthesis of these compounds were also presented here. This is the result of the process of environmental awareness. Additionally, the planet Earth is already showing clear signs of depletion, which is currently decreasing the quality of life.

Synthesis, characterization, biological, and molecular docking assessment of bioactive 1,3-thiazolidin-4-ones fused with 1-(pyrimidin-2-yl)-1H-imidazol-4-yl) moieties

A series of fifteen computationally bioactive 1,3-thiazolidin-4-ones fused with 1-(pyrimidin-2-yl)-1H-imidazol-4-yl moieties (1-15) were synthetically prepared and assessed for antimicrobial potential against the four strains (two gram-positive and two gram-negative). The structures were supported by spectroscopic methods like FT-IR, NMR (H-1 & C-13), mass spectroscopy, etc. The antimicrobial efficacy of the prepared compounds was achieved by the method of disk diffusion, and the effects were recorded in terms of zone of inhibition and minimum inhibitory concentration. Dimethyl sulfoxide and ciprofloxacin were used as negative and positive controls. The results stated that two compounds (7 and 10) were reported to exhibit better antimicrobial activity than the standard drug ciprofloxacin, while the other members represented considerable potential. Molecular docking was also performed to support the in vitro antimicrobial results, to understand the extent of H-bonding and the binding affinities of the compounds (1-15), with the amino acid residues of the receptor GlcN-6P and, represented significant H-bonding. An MTT assay was also carried out to see the toxic effects of the prepared compounds and posed that the compounds were less toxic toward the HepG2 cells. [GRAPHICS] .

In Vitro Effects of the Endocrine Disruptor p,p ‘-DDT on Human Follitropin Receptor

BACKGROUND: 1-chloro-4-[2,2,2-trichloro-1-(4-chlorophenyl) ethyl] benzene (p,p’-DDT) is a persistent environmental endocrine disruptor (ED). Several studies have shown an association between p,p’-DDT exposure and reproductive abnormalities. OBJECTIVES: To investigate the putative effects of p, p’-DDT on the human follitropin receptor (FSHR) function. METHODS AND RESULTS: We used Chinese hamster ovary (CHO) cells stably expressing human FSHR to investigate the impact of p,p’-DDT on FSHR activity and its interaction with the receptor. At a concentration of 5 mu M p, p’-DDT increased the maximum response of the FSHR to follitropin by 32 +/- 7.45%. However, 5 mu M p,p’-DDT decreased the basal activity and did not influence the maximal response of the closely related LH/hCG receptor to human chorionic gonadotropin (hCG). The potentiating effect of p,p’-DDT was specific for the FSHR. Moreover, in cells that did not express FSHR, p,p’-DDT had no effect on cAMP response. Thus, the potentiating effect of p,p’-DDT was dependent on the FSHR. In addition, p,p’-DDT increased the sensitivity of FSHR to hCG and to a low molecular weight agonist of the FSHR, 3-((5methyl)-2-(4-benzyloxyphenyl)- 5-{[2-[3-ethoxy-4-methoxy-phenyl)-ethylcarbamoyl]-methyl}-4-oxo-thiazolidin-3-yl)benzamide (16a). Basal activity in response to p,p’-DDT and potentiation of the FSHR response to FSH by p,p’-DDT varied among FSHR mutants with altered transmembrane domains (TMDs), consistent with an effect of p,p’-DDT via TMD binding. This finding was corroborated by the results of simultaneously docking p, p’-DDT and 16a into the FSHR transmembrane bundle. CONCLUSION: p,p’-DDT acted as a positive allosteric modulator of the FSHR in our experimental model. These findings suggest that G protein-coupled receptors are additional targets of-endocrine disruptors.

Nano-MoO3-mediated synthesis of bioactive thiazolidin-4-ones acting as anti-bacterial agents and their mode-of-action analysis using in silico target prediction, docking and similarity searching

The efficacy of thiazolidin-4-ones as synthons for diverse biological small molecules has given impetus to anti-bacterial studies. Our work aims to synthesize novel bioactive thiazolidin-4-ones using nano-MoO3 for the first time. The compelling advantage of using nano-MoO3 is that the recovered nano-MoO3 can be reused thrice without considerable loss of its catalytic activity. The synthesized thiazolidin-4-ones were tested for anti-bacterial activity against two strains of pathogenic bacteria, namely, Salmonella typhi and Klebsiella pneumoniae. Our results indicated that 3-(benzo[d] isoxazol-3-yl)-2-(3-methoxyphenyl) thiazolidine-4-one (compound 3b) showed significant inhibitory activity towards Salmonella typhi, in comparison with gentamicin. Furthermore, in silico target prediction presented the target of compound 3b as the FtsK motor domain of DNA translocase of Salmonella typhi. Hence, our hypothesis is that compound 3b may disrupt chromosomal segregation and thereby inhibit the division of Salmonella typhi. In addition, similarity searching showed that 34 compounds with a chemical similarity of 70% or higher to compound 3b, which were retrieved from ChEMBL, bound to targets associated with biological processes related to cell development in 36% of the cases. In summary, our work details novel usage of nano-MoO3 for the synthesis of novel thiazolidin-4-ones possessing anti-bacterial activity, and presents a mode-of-action hypothesis.
