Synthesis and biological evaluation of the new 1,3-dimethylxanthine derivatives with thiazolidine-4-one scaffold

Background: The xanthine structure has proved to be an important scaffold in the process of developing a wide variety of biologically active molecules such as bronchodilator, hypoglycemiant, anticancer and anti-inflammatory agents. It is known that hyperglycemia generates reactive oxygen species which are involved in the progression of diabetes mellitus and its complications. Therefore, the development of new compounds with antioxidant activity could be an important therapeutic strategy against this metabolic syndrome. Results: New thiazolidine-4-one derivatives with xanthine structure have been synthetized as potential antidiabetic drugs. The structure of the synthesized compounds was confirmed by using spectral methods (FT-IR, H-1-NMR, C-13-NMR, F-19-NMR, HRMS). Their antioxidant activity was evaluated using in vitro assays: DPPH and ABTS radical scavenging ability and phosphomolybdenum reducing antioxidant power assay. The developed compounds showed improved antioxidant effects in comparison to the parent compound, theophylline. In the case of both series, the intermediate (5a-k) and final compounds (6a-k), the aromatic substitution, especially in para position with halogens (fluoro, chloro), methyl and methoxy groups, was associated with an increase of the antioxidant effects. Conclusions: For several thiazolidine-4-one derivatives the antioxidant effect of was superior to that of their corresponding hydrazone derivatives. The most active compound was 6f which registered the highest radical scavenging activity.

Novel Thiazolidin-4-ones as Potential Non-Nucleoside Inhibitors of HIV-1 Reverse Transcriptase

Background: HIV is the causative agent of Acquired Immunodeficiency Syndrome (AIDS), an infectious disease with increasing incidence worldwide. Non-nucleoside reverse transcriptase inhibitors (NNRTIs) play an important role in the treatment of AIDS. Although, many compounds are already being used as anti-HIV drugs, research for the development of new inhibitors continues as the virus develops resistant strains. Methods: The best features of available NNRTIs were taken into account for the design of novel inhibitors. PASS (Prediction of activity spectra for substances) prediction program and molecular docking studies for the selection of designed compounds were used for the synthesis. Compounds were synthesized using conventional and microwave irradiation methods and HIV RT inhibitory action was evaluated by colorimetric photometric immunoassay. Results: The evaluation of HIV-1 RT inhibitory activity revealed that seven compounds have significantly lower Iota C-50 values than nevirapine (0.3 mu Mu). It was observed that the activity of compounds depends not only on the nature of substituent and it position in benzothiazole ring but also on the nature and position of substituents in benzene ring. Conclusion: Twenty four of the tested compounds exhibited inhibitory action lower than 4 mu Mu. Seven of them showed better activity than nevirapine, while three of the compounds exhibited IC50 values lower than 5 nM. Two compounds 9 and 10 exhibited very good inhibitory activity with IC50 1 nM.

s-Proline Covalented Silicapropyl Modified Magnetic Nanoparticles: Synthesis, Characterization, Biological and Catalytic Activity for the Synthesis of thiazolidin-4-ones

Background: Thiazolidinoneones are important pharmaceutical compounds because of their biological activities. Several methods for the synthesis of 4-thiazolidinones are widely reported in the literature. The main synthetic routes to synthesize 1,3-thiazolidin-4-ones involve three components reaction between amine, a carbonyl compound and thioglycolic acid. Objective: s-Proline covalented silicapropyl modified magnetic nanoparticles (Fe3O4@SiO2-Pr @s-proline) were prepared. The antibacterial activity of synthesized nanoparticles against four bacterias was investigated that showed that 30 Mg/L of synthesized nanoparticles is a suitable concentration for bacterial inhibitory. Finally, the catalytic application of the synthesized s-Proline covalented silicapropyl modified magnetic nanoparticles for the synthesis of thiazolidinones and pyrazolyl thiazolidinones under stirring in aqueous media was evaluated. All of the synthesized organic compounds were characterized by mp, FT IR, H-1 NMR, C-13 NMR and elemental analysis. Materials and Methods: A combination of aldehyde (1.0 mmol), thioglycolic acid (1.0 mmol), various amines (1mmol) and 0.05 g Fe3O4@SiO(2)propyl@L-proline, were reacted at room temperature under stirring in 10 mL water. After completion of the reaction, as indicated by TLC (4:1 hexane: ethylacetate), the reaction mixture was filtered in the presence of an effective magnetic bar to separate the nanocatalyst. The nanocatalyst was washed with a mixture of hot EtOH: H2O two times. The crude products were collected and recrystallized from ethanol, if necessary. Results and Discussion: We present a novel avenue for the synthesis of thiazolidinones in the presence of Fe3O4@SiO2-Pr @s-proline under solvent-free conditions. Conclusion: In conclusion, we have synthesized Fe3O4@SiO2-Pr@s-proline nanoparticles. Their biological activity against 4 bacterias was investigated. It released that 30Mg/L is the suitable concentration of synthesized nanoparticle for bacterial inhibitory. The catalytic efficiency of the catalyst was checked in the multicomponent reaction of various aldehyde, thioglycolic acid and various amines under stirring. This nanoparticle is a new organic-inorganic hybrid nanoparticle. The operational simplicity, the excellent yields of products, ease of separation and recyclability of the magnetic catalyst, waste reduction and high selectivity are the main advantages of this catalytic method.

Graphene Oxide Catalyzed C-N/C-S/[3+2] Cyclization Cascade for Green Synthesis of Thiazolidinone in Water

In this paper, first graphene oxide catalyzed one-pot three-component green synthesis of 1,3-thiazolidin-4-one using amine, aldehyde and mercapto acetic acid in water has been reported. The reaction is affected via sequential C-N and C-S bond formation and ring transformation reactions leading to thiazolidin-4-ones formation. The use of water as solvent at room temperature, good to excellent yields of pure products (75-92%) and operational simplicity are the salient features of the envisaged protocol. The graphene oxide catalyst is very mild, effective and most of its activity is preserved after being reused for five times.

Organocatalytic activity of [3]ferrocenophanes: a computational study

The organocatalytic activity of the recently synthesized diamino[3]ferrocenophanes and the related thioamino[3]ferrocenophane was investigated in the benzoin condensation computationally. The nucleophilicity of these compounds is slightly increased compared to the imidazolidin-2-ylidene, as a consequence of the increased bond angle at the carbene center. Among the possible isomers of the carbene-aldehyde adducts, we have located a hitherto unexplored structure with an oxirane moiety. The isomers of the related carbene-aldehyde adducts including the Breslow intermediates have similar stability in comparison with the imidazolidin-2-ylidene and thiazolidin-2-ylidene, respectively; moreover, the barriers of the interconversion of these adducts are also similar; however, the oxirane-type compound formed from benzaldehyde and the diamino[3]ferrocenophane is significantly stabilized with respect to its isomers. The barrier of the addition of the second aldehyde to the Breslow intermediate increased by 9-15 kcal/mol in case of the [3]ferrocenophanes compared to the 5-membered analogues, which could partly be explained by the higher stabilization of the van der Waals adduct of the Breslow intermediate and the second aldehyde. Since the addition of the second aldehyde is blocked, these carbenes could be suitable for the experimental investigation of the carbene-aldehyde adducts.

Rhodium(II)-Catalyzed Annulative Coupling of beta-Ketothioamides with alpha-Diazo Compounds: Access to Highly Functionalized Thiazolidin-4-ones and Thiazolines

An operationally simple and efficient one-pot protocol for the synthesis of highly functionalized thiazolidin-4-ones and thiazolines has been devised via Rh(OAc)(2)-catalyzed annulative coupling of beta-ketothioamides with diazo compounds under mild reaction conditions for the first time. This double functionalization of diazo compounds proceeds via selective S-alkylation followed by intramolecular N-cyclization enabling the formation of C-S and C-N bonds at moderate temperature. Notably, the product possess Z-stereochemistry with regard to the exocyclic C=C double bond at the 2-position of the ring. Further, the synthetic utility of the strategy has been revealed to 2,3-dihydrobenzo[d]thiazoles. Remarkably, atom economy and tolerance of a wide range of functional groups are added characteristics to this strategy.

Fluorinated thiazolidinols cause cell death in A549 lung cancer cells via PI3K/AKT/mTOR and MAPK/ERK signalling pathways

A series of 2-imino-4-(trifluoromethyl) thiazolidin-4-ol derivatives were synthesized from one pot, three-component reactions of primary amine, aryl isothiocyanate and 3-bromo-trifluoromethyl acetone via in situ generation of both symmetrical and unsymmetrical thioureas. All the synthesized derivatives were screened for their in vitro anti-cancer activity against human cancer cell lines. Compounds 8l, 8r, 8s, 8t and 8u exhibited more potent anticancer activity in lung cancer cells (A549) than in the other three cell lines. Data obtained from analysis of the cell cycle showed that treatment of lung cancer cells with these compounds resulted in G0/G1 cell cycle arrest. Studies to understand the molecular mechanism of action of these compounds suggest that the compounds inhibit PI3K, pAkt and mTOR protein expression with concomitant up-regulation of tumor suppressor PTEN. These compounds contributed to LC-3 mediated cytoplasmic vacuolation leading to cell death in lung cancer cells. Overall, these compounds modulate cell death processes via inhibition of PI3K/Akt/mTOR and MEK/ERK pathways, the key growth factor signalling pathways implicated in abnormal cell proliferation. These molecules can therefore be further tested in in vivo models as a potential regimen for efficacy and effectivity in lung cancer.
