Their structures have been elucidated from UV-Vis, IR, ¹H NMR and mass spectral data. Among the synthesized derivatives <b style="">5, 6, 7</b> and <b style="">10</b> are found to have a potent anti-inflammatory response whereas compounds <b style="">1, 4, 5, 8</b> and <b style="">10</b> have an effective analgesic response. There is no remarkable difference in bioactivity of pyrazolones derived from aliphatic and aromatic aldehydes. All the experimental data are statistically significant at p<0.05. <br/> <br/>Page(s): 1671-1674 http://nopr.niscair.res.in/handle/123456789/10737 Title: Synthesis of <i style="">N-</i>1-(3,5-dimethyl-4-isoxozolyl)-3-(4-aryl-5-thioxo-4,5-dihydro-1-<i style="">H</i>–1, 2, 4-triazol–3-yl)propanamides as possible antitumor agents <br/> <br/>Authors: Reddy, Ch V Narsimha; Raju, S; Reddy, M Nagi; Rajanarendar, E <br/> <br/>Abstract: Synthesis of <i style="">N</i>-1 (3, 5-dimethyl-4-isoxazolyl)-3-(4-aryl-5-thioxo-4,5-dihydro-1<i style="">H</i>-1,2,4-triazol-3-yl)-propanamides <b style="">7 </b>have been accomplished from 4-amino-3,5-dimethylisoxazole <b style="">1</b> in five steps. The structural elucidation of the synthesized compounds has been performed by IR, ¹H NMR and mass spectroscopic data besides elemental analyses. <br/> <br/>Page(s): 1667-1670
