Synthesis of Some Novel 2-Azetidinones/4-Thiazolidinones Bearing 1, 3, 4-Thiadiazole Nucleus and Screening for its Anti-Imflammatory Activity

Objective: The objective of the study was to synthesize a series of 3-chloro-4-(substituted phenyl)-1-(5-styryl-1, 3, 4-thiladiazole-2-yl) azetidin-2-one / 2-(substituted phenyl)-3-(5-styryl-1, 3, 4-thiadiazole-2-yl)-thiazolidin-4-one and screened for their possible anti-inflammatory activity by carrageenan induced paw edema in rats. Method: The synthesis of 2-amino-5-styryl-1, 3, 4-thiadiazole, an intermediate was carried out by oxidative cyclization method. In the current study, thiosemicarbazone (I) was subjected to oxidative cyclization using ferric chloride as an oxidising agent, to get 2-amino-5-styryl-1, 3, 4-thiadiazole (II). Futhermore, compound (II) was reacted with different aromatic aldehydes in methanol to form N-(4-sustituted)-5-styryl-1, 3, 4-thiadiazol-2-amine (III a-h). Compound (III a-h) was reacted with chloroacetyl chloride in triethylamine to form 2-azetidinone derivatives bearing 1, 3, 4-thiadiazole nucleus (IV a-h). Compound (III a-h) on cyclocondensation with mercaptoacetic acid leads to the formation of 4-thiazolidinone derivatives bearing 1, 3, 4-thiadiazole nucleus (V a-h). Results: The synthesis of the targeted compounds IV a-h and Va-h was confirmed through their MP, IR, H-1-NMR and mass spectrum studies. Compounds IVa, IVb and IVc (56.32, 61.11 and 58.24 % inhibition) exhibited significant anti-inflammatory activity than that of diclofenac (65.13% inhibition). Conclusion: It may be concluded that the presence of methoxy, nitro and hydroxyl phenyl groups substituting 2-azetidinone bearing 1, 3, 4-thiadiazole showed significant anti-inflammatory activity.

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. Furthermore, this new avenue is inexpensive and environmentally benign.

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.

Design, synthesis, and preliminary pharmacological evaluation of novel thiazolidinone derivatives as potential benzodiazepine agonists

Thiazolidinones are well-known heterocycles that demonstrate promising biological effects such as anticonvulsant activity. Hybridization of these chemicals with scaffold, which has necessary pharmacophores for binding to the benzodiazepine receptors, can prompt a novel structure possessing extensive anticonvulsant effects. In this study, novel derivatives of thiazolidinone as new benzodiazepine agonists were designed, synthesized, and biologically evaluated. Compound 5h, 4-chloro-2-(2-fluorophenoxy)-N-(4-oxo-2-(p-tolyl)thiazolidin-3-yl)benzamide, exhibited considerable anticonvulsant activity, proper sedative-hypnotic effect, no memory impairment, and no muscle relaxant effect. The pharmacological effects of the designed compounds were antagonized by flumazenil, which confirmed the benzodiazepine receptors’ involvement in their biological effects. Based on in silico calculations of ADME properties of our novel compounds, they could be active oral agents potentially. Graphic abstract In this study, we designed novel structures by the hybridization of thiazolidinone moiety with scaffold which has necessary pharmacophores for binding to the benzodiazepine receptors. The results are very promising for developing new lead compounds as benzodiazepine agonists possess anticonvulsant effects. [GRAPHICS]

Synthesis of novel N-substitutedphenyl-6-oxo-3-phenylpyridazine derivatives as cyclooxygenase-2 inhibitors

Some novel non-ulcerogenic N-substitutedphenyl-6-oxo-3-phenylpyridazines as COX-2 inhibitors have been developed (Supplementary material Appendix1). The novel aldehyde3was prepared by reacting 6-phenylpyridazin-3(2H)-one with 4-fluorobenzaldehyde. The aldehyde3was reacted with different hydrazines and thiazolidin-4-ones to obtain the novel N-substitutedphenyl-6-oxo-3-phenylpyridazine derivatives. These were assessed for their anti-inflammatory potential and gastric ulcerogenic effects. The molecular docking investigations were also undertaken. The spectroscopic data were coherent with the allocated structures of the compounds. The compounds4a(IC50= 17.45 nm;p< .05),4b(IC50= 17.40 nm;p <.05),5a(IC50= 16.76 nm;p< .05), and10(IC50= 17.15 nm;p< .05) displayed better COX-2 inhibitory activity than celecoxib (IC50= 17.79 nm;p< .05). These findings were consistent with the molecular docking investigations of4a,4b,5a, and10. Thein vivoanti-inflammatory profile of4a,4b,5a, and10was also superior to celecoxib and indomethacin. The compounds4b,5a, and10revealed no gastric ulcerogenic effects, wherein the compound4aproduced almost negligible gastric ulcerogenic effects than celecoxib and indomethacin. The compounds4a,4b,5a, and10have been postulated as promising non-ulcerogenic COX-2 inhibitors. Interested yet?
