Siva PY - 2010/12/26 Y2 - 2025/09/23 TI - Synthesis and anti-oxidant activity of novel 6,7,8,9 tetra hydro- 5H-5-(2'-hydroxy phenyl)-2-(4'-substituted benzylidine)- 3-(4-nitrophenyl amino) thiazolo quinazoline derivatives JF - Research in Biotechnology JA - RIB VL - 1 IS - 1 SE - Research Articles DO - UR - https://www.updatepublishing.com/journal/index.php/rib/article/view/2329 SP - AB - In the present study, a series of novel thiazolo quinazoline derivatives were<br />synthesized by condensation of different aromatic aldehydes with 4-nitro aniline. The chemical structures of the synthesized compounds were confirmed by means of IR, 1H-NMR, mass spectroscopy and elemental analyses. These compounds were screened for anti-oxidant activity by DPPH radical assay, nitric oxide scavenging activity and Hydrogen Peroxide scavenging activity. Among the synthesized compounds 5d, 5c and 5b was found to be the most potent anti-oxidant activity.<br /><br /> ER -
