Synthesis of Various Schiff Bases Containing Isoxazole Ring and Their Applications with Thioglycollic Acid and Diverse Phosphorus Reagents

[GRAPHICS] A series of Schiff bases bearing isoxazole and pyrazole rings were synthesized. Application of thioglycollic acid on two selective synthesized Schiff bases afforded the corresponding thiazolidin-4-one derivatives. On the other hand, following the multicomponents one-pot Kabachnik-Fields reaction, the Schiff base generated in situ from 4-chlorobenzaldehyde and 5-methyl isoxazol-3-amine was trapped by phosphorus reagents to produce the corresponding amino phosphonates in moderate yields. However, the latter products could also be obtained in better yields (>= 78%) by directly applying the dialkylphosphites to a selective synthesized Schiff base. Similarly, a series of alpha-aminophosphonates could be obtained from 5-chloro-3methyl- 1H-pyrazol-4-carbaldehyde, 5-methylisoxazol-3-amine, and phosphorus reagents. Moreover, applying hexaalkyl triamido phosphites to the N-(4-chlorobenzylidene)-5-methylisoxazol-3-amine in ethanol afforded methylphosphonic diamide derivatives, whereas N-((5-chloro-3-methyl-1H-pyrazol-4-yl) methylene)5- methylisoxazol-3-amine underwent dechlorination through reaction with hexaalkyl triamido phosphites to give the respective amine derivatives.

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.

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] .

THE ANALGESIC EFFECT OF 1,3-THIAZOLIDIN-4-ONE DERIVATIVES AS POTENTIAL MODULATORS OF THE SEROTONINERGIC SYSTEM

This study presents the synthesis and evaluation of the analgesic effect of 1,3-thiazolidin-4-one derivatives. Tested compounds were prepared by the cyclization reaction of appropriate N-substituted carboxylic acid hydrazide derivatives with mercaptoacetic acid. The purpose of this study was the evaluation of the analgesic properties of 1,3-thiazolidin-4-one derivatives. In addition to this, we tried to explain the role of serotonin receptors in the antinociceptive mechanisms of tested compounds. The experiments were carried out using male Albino Swiss mice (20-25g). The compounds were administered intraperitoneally (ip) and were analysed for analgesic activities in models of pain in mice. Additionally, they were tested for safety on the central nervous system of mice in selected behavioural tests. Our results revealed an interesting analgesic activity of the tested compounds. The tested derivatives showed low toxicity, reflected by their LD50 value. Moreover, none of these compounds exhibited neurotoxic properties or impaired the cognitive activity of mice, even at the highest doses used. All tested derivatives showed analgesic activity. Among the tested compounds, N-[2-(4-methylphenyl)-4-oxo-1,3-thiazolidin-3-yl] acetamide seems to be the most effective painkiller. It has a pronounced antinociceptive effect towards thermal and mechanical pain stimulation. The present results support the idea that 5-HT receptors play an important role in the control of pain. The compounds that modulate 5-HT receptors activity may have clinical utility in pain therapy.
