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.

Design and synthesis of new drugs inhibitors of Candida albicans hyphae and biofilm formation by upregulating the expression of TUP1 transcription repressor gene

Candida albicans is a common human fungal pathogen that causes disease ranging from superficial to lethal infections. C. albicans grows as budding yeast which can transform into hyphae in response to various environmental or biological stimuli. Although both forms have been associated with virulence, the hyphae form is responsible for the formation of multi-drug resistance biofilm. Here, new compounds were designed to selectively inhibit C. albicans hyphae formation without affecting human cells to afford sufficient safety. The newly designed 5-[3-substitued-4-(4-substituedbenzyloxy)-benzylidene]-2-thioxo-thiazolidin-4-one derivatives, named SR, showed very specific and effective inhibition activity against C. albicans hyphae formation. SR compounds caused hyphae inhibition activity at concentrations 10-40 fold lower than the concentration required to inhibit Candida yeast and bacterial growths. The anti-hyphae inhibition activities of SR compounds were via activation of the hyphae transcription repressor gene, TUP1. Correlation studies between the expression of TUP1 gene and the activity of SR compounds confirmed that the anti-C. albicans activities of SR compounds were via inhibition of hyphae formation. The newly designed SR compounds showed 10-40% haemolytic activity on human erythrocytes when compared to 100% haemolysis by 0.1% triton employed as positive control. Furthermore, theoretical prediction of absorption, distribution, metabolism, excretion, and toxicity (ADMET) of SR compounds confirmed their safety, efficient metabolism and possible oral bioavailability. With the minimal toxicity and significant activity of the newly-designed SR compounds, a future optimization of pharmaceutical formulation may develop a promising inhibitor of hyphal formation not only for C. albicans but also for other TUP1- dependent dimorphic fungal infections.

A facile and highly chemoselective synthesis of 1-thia-3a,6-diaza-benzo[e]azulen-3-ones by 7-exo-dig/trig halocyclizations

This manuscript describes a study on relatively unexplored halogen mediated 7-exo-dig/trig cyclization reactions of 2-(2-amino-aryl)-3-prop-2-ynyl/allyl-thiazolidin-4-ones for the formation of thiazole condensed 1,4-benzodiazepines in good yields. The reactions are facile, chemoselective and involve the use of simple substrates leading to synthesis of diversely functionalized 1,4-benzodiazepines. The synthesis of such condensed 1,4-benzodiazepines is important in terms of their usefulness as biological active agents.

Catalytic Asymmetric Conjugate Addition and Sulfenylation of Diarylthiazolidin-2,4-diones

This work reports the first application of diarylthiazolidin-2,4-diones as nucleophiles in asymmetric catalysis. By utilizing chiral amino acid-based (thio)urea tertiary amines as the catalysts, we successively established asymmetric conjugate addition to nitroolefins and sulfenylation to N-(sulfanyl)-succinimides of diarylthiazolidin-2,4diones. Two series of biologically important 5-aryl-5-substituted thiazolidin-2,4-diones were obtained with high enantio- and diastereoselectivities (up to >99% ee and >19:1 dr). The enantio enriched adducts were found to show satisfactory anticancer activities against three different cancer cell lines using the MTT assay. All of these successes depended on the development of a general and expedient synthetic strategy to provide diverse 5H-thiazolidin-2,4-diones.
