All the newly obtained thiazolidin-4-ones have been fully characterized by HRMS and H-1 and C-13 (1D and 2D) NMR spectroscopy. Two of them, i.e. 2 and 3, were identified by single-crystal X- ray crystallography, confirming the synthetic pathway and the spectroscopic analyses. In 3, there are two roughly identical molecules within the asymmetric unit with the same absolute configuration. These two molecules are linked through N-H center dot center dot center dot O hydrogen bonds, building an R-2(2)(8) graph-set motif.

Design, synthesis and immunomodulating activity of C-pseudonucleosides containing thiazolidin-4-one and phenyl connected by acetamide bond

Several novel C-pseudonucleosides containing thiazolidin-4-one and phenyl connected by acetamide bond were rationally designed and easily synthesized at room temperature by using the unprotected sugar aldehyde as the starting material. The effects of the compounds on Con A-induced T cell proliferation were evaluated at five concentrations of 5, 10, 25, 50, and 100 mu mol/L Interestingly, compounds 7a and 8a = 2, R = H) exhibited immunostimulating activities, while compounds 5a, 6a (n = 1, R = H) and 7b, 8b (n = 2, R = CH3) showed immunosuppressive activities. Another two compounds 5b and 6b (n = 1, R = CH3) had no immunomodulating activities. These initial biological results suggested that subtle structural changes to the phenyl and acetamide bond of C-pseudonucleosides could have a significant effect on T cell proliferation bias, although it was difficult to formulate a rigorous structure activity relationship based on the observed activities.

Synthesis of tetracyclic iminosugars fused benzo[e][1,3]thiazin-4-one and their HIV-RT inhibitory activity

Several aza-C-pseudonucleosides bearing 1,3-benzothiazin-4-one (6 and 7) were prepared by the one-pot three-component condensation from the iminosugar aldehyde 3, amino acid ethyl/methyl ester hydrochlorides 4(a-c), and 2-mercaptobenzoic acid 5. After removal of Boc and the isopropylidene groups, the target novel tetracyclic iminosugars fused benzo[e][1,3]thiazin-4-one 1(a-c) and 2(a-b) were first afforded by the intramolecular cyclo-amidation reaction. Their structures were determined by their H-1, C-13 NMR, and HRMS (ESI) spectra and X-ray. The tetracyclic iminosugars 1(a-c) and 2(a-b) were examined for their HIV reverse transcriptase (RT) inhibitory activities. The result showed that all compounds could effectively inhibit RT activity. Among them, compound 2a was the best one with the IC50 value of RT inhibitory activity of 0.82 mu M. Structure-activity relationship analysis suggested that 1’R configuration in the tetracyclic azasugars was of benefit to their anti-HIV RT activity. (C) 2016 Elsevier Ltd. All rights reserved.

Design, Synthesis and In vitro Biological Activity of Some New 1,3-thiazolidine-4-one Derivatives as Chemotherapeutic Agents using Virtual Screening Strategies

Aims: Designing of a new series of derivatives possessing thiazolidine-4-one moiety, their virtual screening using various computational tools, synthesis of prioritized compounds, spectral characterization and biological evaluation along with the comparison of in silico & in vitro results. Background: WHO has come up with a list of antibiotic-resistant priority pathogens i.e. families of bacteria, that pose the greatest threat to human health. Some virulent bacteria are focused in the present study namely Mycobacterium tuberculosis (multi drug resistant), Staphylococcus aureus (methicillin-resistant) Streptococcus pneumoniae, (penicillin-non-susceptible) and Pseudomonas aeruginosa (Carbapenem-resistant) One of the neglected pathogenic disease which needs an urgent attention is Leishmaniasis which has a major burden among the poorest segments of populations in Asia, Africa, and South America. Objective: 1. To design of a series of new heteroaryl-l,3-thiazolidin-4-one derivatives. 2. To prioritize the molecules for synthesis using virtual screening techniques. 3. To synthesize the virtually predicted molecules via different synthetic schemes. 4. To characterize the synthesized molecules by spectroscopic analysis. 5. To evaluate the synthesized compounds for in vitro biological activity. Methods: A series of new heteroaryl thiazolidine-4-one derivatives was designed and subjected to in silico prioritization using various virtual screening strategies. The prioritized thiazolidinone derivatives were synthesized and screened for their in vitro antitubercular, anticancer, antileishmanial and antibacterial (Staphylococcus aureus; Streptococcus pneumonia; Escherichia coli; Pseudomonas aeruginosa) activities. Results: The compounds with electronegative substitutions exhibited positive antitubercular activity, the derivatives possessing a methyl substitution exhibited good inhibitory response against breast cancer cell line MCF-7 while the compounds possessing a hydrogen bond acceptor site like hydroxyl and methoxy substitution in their structures exhibited good in vitro antileishmanial activity. Some compounds exhibited potent activity against gram positive bacteria Pseudomonas aeruginosa as compared to the standards. Conclusion: The designed compounds exhibited good in vitro anti-infective potential which was in good agreement with the in silico predictions and they can be developed as important lead molecules for anti-infective and chemotherapeutic drug research.

Design, synthesis and anticervical cancer activity of new benzofuran-pyrazol-hydrazono- thiazolidin-4-one hybrids as potential EGFR inhibitors and apoptosis inducing agents

This study represents the synthetic approaches of a new set of 2-(((3-(benzofuran-2-yl)-1-phenyl-1H-pyrazol-4-yemethylene)hydrazono)-5-(aryl)thiazolidin-4-one derivatives 4-22 aiming to obtain new antiproliferative candidates against human cervix carcinoma cells (Hela) of EGFR PK inhibiting potency. The cancer cells represented promising sensitivity towards the compounds 6, 7, 11, 13, 14, 16, 17 more than or equal to that against the reference drug doxorubicin. In addition, the latter compounds were tested as EGFR protein kinase inhibitors. The results revealed that compound 14 showed more significant EGFR PK inhibitory activity than the reference drug erlotinib (IC50; 0.07, 0.08 mu M, respectively). Moreover, cell cycle analysis and apoptosis assay were performed for compound 14 proving its ability to cause G1/S phase arrest and apoptosis in Hela cancer cells, in addition to its activation of the caspases-7 and -3. In addition, derivative 14 increased the expression level of p53 and the ratio of Bax/Bcl-2 which confirmed its mode of action. Molecular docking study of 14 was performed to investigate its binding mode of interaction with EGFR PK in the active site with the aim of rationalizing its promising inhibitory activity. Accordingly, compound 14 might be considered as a promising scaffold anticervical cancer chemotherapeutic and deserves further optimization and in-depth biological studies.

Aryl quinolinyl hydrazone derivatives as anti-inflammatory agents that inhibit TLR4 activation in the macrophages

A series of aryl 7-chloroquinolinyl hydrazone derivatives (3a-u) have been synthesized in 55-76% yield using simple reaction condition. The synthesized compounds were evaluated for their anti-inflammatory activities based on their ability to inhibit pro-inflammatory cytokine secretion from the macrophages after stimulation with lipopolysaccharide (LPS). Three compounds appeared as promising anti-inflammatory agents. The mechanism of inflammatory activity of the potent compound 3e was further investigated using a series of biochemical, molecular and microscopic techniques. Further structure activity relationship (SAR) study was carried out to validate the anti-inflammatory activities of the active compounds. Our experimental data revealed that the active moiety i.e. compound 3e majorly causes inhibition of TLR4 signaling pathway and this appears to be the novel functional attribute of this compound.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 85-42-7, you can contact me at any time and look forward to more communication. Quality Control of Hexahydroisobenzofuran-1,3-dione.
