Background: Recently, there has been a lot of scientific interest in exploring the syntheses of oxygen and nitrogen-containing heterocyclic compounds due to their pharmacological activities. In addition, benzisoxazoles play a very important role in organic synthesis as key intermediates. Objective: In this paper, we focused on developing a novel synthetic route for biologically active arylisoxazoles under normal conditions, and simplified it to get high purities and yields, and also reported their anti-inflammatory activities. Method: An efficient and simple method has been explored for the synthesis of novel 3-methyl arylisoxazoles from o-nitroaryl halides via o-ethoxyvinylnitroaryls, using dihydrated stannous chloride (SnCl2.2H2O) in MeOH / EtOAc (1:1) via Domino rearrangement in one pot synthesis. Result: We synthesized novel 3-methylarylisoxazoles from o-nitroarylhalides via o-ethoxyvinylnitroaryls, using dihydrated stannous chloride (SnCl2.2H2O) in MeOH / EtOAc (1:1) via domino rearrangement. In this reduction, nitro group and ethoxy vinyl group change to the functional acyl ketones, followed by hetero cyclization. Here, the reaction proceeds without the isolation of intermediates like 2-acylnitroarenes and 2- acylanilines. All the synthesized compounds were completely characterized by the NMR and mass spectra. The compounds were also explored for their anti-inflammatory activity by carrageenan-induced inflammation in the albino rats (150-200 g) of either sex used in this entire study with the use of Diclofenac sodium as the standard drug. The initial evaluations identified leading targets with good to moderate anti-inflammatory activity. Conclusion: A simple, one-pot and convenient method has been explored for the synthesis of novel 3- methylarylisoxazoles with high purity and reaction yields. All the compounds 3a, 3c, 3d, 3f, 3g and 3h exhibited 51-64% anti-inflammatory activities.

Silva Manso, family- convolvulaceae, is an important plant in Indian conventional system of medicine which is extensively employed by different tribes in many countries to cure edema and painful conditions like arthritis, back pain; hyperlipidemia, diabetes mellitus, liver disorders, skin disorders and to regulate bowel functions. Objective: The roots of O. turpethum (Linn.) was subjected to physicochemical, phytochemical standardization, the chromatographic separation which was accomplished by column chromatography, TLC, and HPTLC, further, the acute toxicity, cytotoxic and anti-inflammatory activities of Operculina turpethum roots were estimated by in vivo and in vitro models. Materials and Methods: This study includes percentage yield of extraction, organoleptic evaluation along with the analysis of its physicochemical investigations & preliminary phytochemical estimation. The isolation of active phytoconstituents was done by column chromatography, and the isolated compound was then exposed to TLC and HPTLC analysis. Cytotoxic activity was tested by WST-1 based cell viability assay on HepG2 cells. Anti-inflammatory activity of methanol extract (ME) was evaluated against inflammation occur by both in vitro and in vivo method. Results: The methanolic extract exhibited the presence of most of the phytoconstituents out of all the extracts, the phytoconstituent phytosterol, i.e., β-sitosterol was isolated by column chromatography, identified and quantified by TLC and HPTLC, which is liable for anti-inflammatory activity. The amount of β-sitosterol was estimated to be 14.09 µg in 10.00 mg fraction of MEOT. MEOT is devoid of toxicity up to 2000 mg/kg in Wistar albino rats. It was analysed that in vitro anti-inflammatory activity of MEOT by egg albumin denaturation method exhibited a incredible decrement in turbidity and increasing the percentage inhibition of albumin denaturation (60.52%) in MEOT treated group as compared with control group. In egg albumin-induced edema in rats, MEOT at the dose of 400 mg/kg reduced the edema formation (3.03 ± 0.02) induced by egg albumin at 4th h. In cotton pellet-induced granuloma in rats, MEOT at the dose of 400 mg/kg displayed maximum granuloma inhibition (51.06%) which is similar to that of indomethacin. Conclusion: From the obtained findings it is confirmed that O. turpethum contains β-sitosterol which is responsible for potent anti-inflammatory activity without causing cytotoxicity to the plant. The results suggested that ME of O. turpethum roots had high potential for application as an anti-inflammatory agent. The recognization and confirmation of the plant can be obtaineded from the study and will present data which is aidful in determining the quality and purity of a crude drug which further helps in preventing its adulteration.

The anti-inflammatory activity of hydroxytriazenes as well as their vanadium complexes has been studied using carrageenan induced hind paw oedema method in albino rats (Wister strain). Hydroxytriazenesviz., 3-hydroxy-1,3-diphenyltriazene(HT-1), 3-hydroxy-3-phenyl-1-(4-sulfonamido)phenyl triazene(HT-2), 3-hydroxy-3-p-chlorophenyl-1-(4-sulfonamido) phenyltriazene(HT-3), 3-hydroxy-3-m-chlorophenyl-1-(4-sulfonamido)phenyltriazene(HT-4)(HT-4) and their respective vanadium complexes C-1, C-2, C-3 and C-4 have been synthesized using standard methods, purified, characterized and used for studying their anti-inflammatory activities. The hind paw oedema was produced by subplanter injection of carrageenan and the paw volume was measured plethysmographically after 0.5, 1, 2, 3 and 5 h. The animals were givenHT-1, HT-2, HT-3andHT-4and also vanadium complexes C-1, C-2, C-3 and C-4 dissolved inDMSO(at dose 5 mg/Kg body weight). Diclofenac sodium (5 mg/kg) was used as a standard drug. The standard drug shows maximum inibition up to 1h as 81.73% which goes on increasing up to 3h (88.94%) but further reduces to 74.93% at the end of 5 h. The test compounds i.e. both ligands as well as their metal complexes show maximum percent inhibition only up to 1h. after which the efficacy reduces. Thus it can be said that both ligands as well as their vanadium complexes show very significant anti-inflammatory activity up to 1h which is comparable to standard drug.

AbstractThe objective of this work was to study the analgesic and anti-inflammatory activity ofHealthy albino rats (150–200 g) and mice (25–50 g) were arranged and divided into five groups. Group 1 received distilled water and served as control, groups 2, 3, 4 were treated with TG stem extract (100, 200, 400 mg/kg) and group 5 received standard drug. For analgesic activity, the radiant heat method and writhing test were used, and for anti-inflammatory activity, the paw oedema model and granuloma pouch method were used. Statistical analysis was done by one-way analysis of variance followed by the t-test.In the radiant heat method, there was a dose-dependent increase in reaction time in TG stem extract (100, 200, 400 mg/kg) and standard drug (buprenorphine). In the writhing test, TG stem extract (200, 400 mg/kg) and aspirin decreased the number of writhes which was significant (p<0.01, p<0.001) as compared to controls. The percentage protection was 8.88%, 15.55%, 22.22% and 35.55% in groups 2, 3, 4 and 5, respectively. In the rat paw oedema test, TG stem extract (200, 400 mg/kg) and aspirin showed 20%, 40% and 54% inhibition of oedema which was statistically significant (p<0.05, p<0.01, p<0.001), respectively, as compared to control at the end of 4 h. In the granuloma pouch method, TG stem extract (100, 200, 400 mg/kg) and aspirin showed 13.33%, 22.22%, 33.33% and 66.66% inhibition of granuloma, respectively, which was significant (p<0.05, p<0.01, p<0.001).TG stem extract possesses significant anti-inflammatory and analgesic activity.
