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.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 115-96-8, in my other articles.

ANALGESIC AND ANTI INFLAMMATORY ACTIVITY OF NEW SUBSTITUTED THIAZOLIDIN-4-ONE DERIVATIVES

4-thiazolidinones are among the most extensively investigated class of organic compounds. Thiazolidin-4-one has been considered as magic moiety, which is a core structure in various synthetic pharmaceuticals displaying a broad spectrum of biological activities. They are widely used as anti-inflammatory, anticonvulsant, analgesic, antimicrobial, anti-HIV, CNS depressant, carcinostatic, antihypertensive and cytotoxic. In view of the wide spectrum activities of condensed 4-thiazolidinones, itwas thought worthwhile to undertake the synthesis of heterocyclic systems in which 4-thiazolidinone nucleus is linked to another biologically active moiety. Semicarbazide/Thiosemicarbazide was reacted with benzoyl chloride to obtain N-hydrazinocarbonyl benzene-1-carboxamide/N-hydrazinocarbothioyl benzene-1 carboxamide respectively. These were then condensed with various aldehydes to yield the intermediate Schiff bases. Thiazolidin-4-ones were prepared by the reaction of Schiff bases with mercaptoacetic acid in dry benzene by refluxing for 16-18 hours. The purity of the compounds synthesized was established by TLC. The synthesized derivatives were characterized by FT-IR, (HNMR)-H-1 and Mass spectral analysis. All the derivatives synthesized were screened for their analgesic and anti inflammatory potency. The compounds 3A3, 3A5,3B2, 3B6 have shown equipotent analgesic activity when compared to standard Ibuprofen. The compounds 3A2, 3A5, 3B2, and 3B3 have been evaluated for their antiinflammatory properties at a dose of 50 mg/kg using carrageenan induced rat paw edema method. All the tested compounds exhibited significant anti-inflammatory activity in acute inflammatory models in rats. Compounds 3A2, 3A5, 3B2, and 3B3 exhibited significant reduction in edema volume when compared to standard Ibuprofen.

Unexpected regiospecific formation and DNA binding of new 3-(acridin-9-yl)methyl-2-iminothiazolidin-4-ones

New 3-(acridin-9-yl)methyl-2-substituted imino-1,3-thiazolidin-4-ones were regiospecifically synthesized from unstable (acridin-9-yl)methyl thioureas and methyl bromoacetate (MBA) or bromoacetyl bromide (BAB). Unexpected formation of only one thiazolidinone regioisomer with both the reagents was due to a new mechanism involving a transient spiro 9,10-dihydroacridine intermediate. These results are in contrast with the reactions of acridin-9-yl thioureas with MBA/BAB that afforded two different thiazolidinone regioisomers with these reagents. UV-vis titrations, CD spectra, and fluorescence quenching have shown that new products intercalated into calf thymus (CT) DNA, and displaced ethidium bromide (EB) from a CT DNA EB complex. Intrinsic binding constants, K-b, and Stern-Volmer constants, K-SV, were found in the range 0.79×10(5) -2.85×10(5) M-1 and 17950-3360 M-1, respectively. The strongest binding affinity was found for an electron donated 2-(4-methoxyphenylimino)thiazolidinone. Additional evidence for DNA intercalation was obtained from thermal denaturation studies. Gel electrophoresis has proven that thiazolidinone products nicked the supercoiled plasmid DNA in 5.0 mu M concentration.

Preparation of thiazolidin-4-one derivatives using ZnO-NiO-NiFe(2)O(4)nano-composite system

The hydrothermal synthesis of ZnO-NiO-NiFe(2)O(4)nano-composite is reported. The sample was utilized to characterize via XRD, FE-SEM, EDS, FT-IR, UV-Vis, and BET techniques. The sample consisted of three different phases as ZnO (hexagonal), NiO (cubic), and NiFe2O4(cubic) with the average particle size as 34 nm and specific surface area, average pore diameter, and pore volume as 64.35 m(2) g(-1), 13.02 nm, and 0.201 cm(3) g(-1), respectively. Catalytic behavior of the nano-composite was investigated on the synthesis of thiazolidin-4-one derivatives under thermal and ultrasonic irradiation condition. Our results show that the catalytic activity of ZnO-NiO-NiFe(2)O(4)nano-composite is much higher than ZnO, NiO, and NiFe(2)O(4)metal oxides. All products were prepared in high yields with short reaction times. In addition, the catalyst was recovered for at least five times.

2-(2-Methoxyphenyl)-3-((Piperidin-1-yl)ethyl)thiazolidin-4-One-Loaded Polymeric Nanocapsules: In Vitro Antiglioma Activity and In Vivo Toxicity Evaluation

Among gliomas types, glioblastoma is considered the most malignant and the worst form of primary brain tumor. It is characterized by high infiltration rate and great angiogenic capacity. The presence of an inflammatory microenvironment contributes to chemo/radioresistance, resulting in poor prognosis for patients. Recent data show that thiazolidinones have a wide range of pharmacological properties, including anti-inflammatory and antiglioma activities. Nanocapsules of biodegradable polymers become an alternative to cancer treatment since they provide targeted drug delivery and could overcome blood-brain barrier. Therefore, here we investigated the in vitro antiglioma activity and the potential in vivo toxicity of 2- (2-methoxyphenyl) -3- ((piperidin-1-yl) ethyl) thiazolidin-4-one-loaded polymeric nanocapsules (4L-N). Nanocapsules were prepared and characterized in terms of particle size, polydispersity index, zeta potential, pH, molecule content and encapsulation efficiency. Treatment with 4L-N selectively decreased human U138MG and rat C6 cell lines viability and proliferation, being even more efficient than the free-form molecule (4L). In addition, 4L-N did not promote toxicity to primary astrocytes. We further demonstrated that the treatment with sub-therapeutic dose of 4L-N did not alter weight, neither resulted in mortality, toxicity or peripheral damage to Wistar rats. Finally, 4L as well as 4L-N did not alter makers of oxidative damage, such as TBARS levels and total sulfhydryl content, and did not change antioxidant enzymes SOD and CAT activity in liver and brain of treated rats. Taken together, these data indicate that the nanoencapsulation of 4L has potentiated its antiglioma effect and does not cause in vivo toxicity. [GRAPHICS] .

Molecular Structure, FT-IR, NMR (C-13/H-1), UV-Vis Spectroscopy and DFT Calculations on (2Z, 5Z)-3-N(4-Methoxy phenyl)-2-N ‘(4-methoxy phenyl imino)-5-((E)-3-(2-nitrophenyl)allylidene) thiazolidin-4-one

In this study, some molecular properties of (2Z, 5Z)-3-N(4-methoxy phenyl)-2-N'(4-methoxy phenyl imino)-5-((E)-3-(2-nitrophenyl) allylidene) thiazolidin-4-one(MNTZ) are evaluated using a combination of spectroscopic characterization (FT-IR, H-1- and C-13 NMR chemical shifts) and theoretical calculations. Molecular geometry, vibrational wavenumbers, gauge-independent atomic orbital (GIAO), H-1 and C-13 chemical shift values and NBO analysis are investigated using B3LYP and PBE functionals with the 6-31G(d,p) basis set in the ground state. The calculated geometrical parameters and vibrational spectra are compared to available experimental data and each vibrational frequency is assigned on the basis of potential energy distribution (PED). The electronic transitions are calculated using time-dependent density functional theory (TDDFT). The energy band gap between the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies are obtained by computing the frontier molecular orbitals using the B3LYP/6-31G(d,p) and PBE/6-31G(d,p) levels along with the global reactivity descriptors. Mulliken atomic charges and molecular electrostatic potential (MEP) are simulated using both functionals to find more reactive sites for electrophilic and nucleophilic attack. Finally, the thermodynamic functions (heat capacity, entropy, and enthalpy) from spectroscopic data are obtained and discussed in the range of 100-1000 K.
