title: Synthesis of Some New Isoxazoline Derivatives of Chalconised Indoline 2-one as a Potential Analgesic, Antibacterial and Anthelmimtic Agents.
abstract: A series of novel 1[5"-(2"'-substituted phenyl)-4",5"'-dihydro isoxazole-3"-yl]-3-[(4 substituted phenyl)imino]1-3-dihydro-2H-indole-2-one were synthesized from different substituted chalconised indole-2,3-dione was prepared from the different chalconised Isatin. The structures of the compounds were elucidated by elemental and spectral (IR, (1)H NMR, and MS) analysis. The synthesized compounds were screened for their analgesic activity by the acetic acid induced Writhing method and in vitro antimicrobial activity against the Gram-positive bacteria-Staphylococcus aureus and the Gram-negative bacteria-Pseudomonas auroginosa, Pseudomonas mirabilis, and E. coli by the cup plate agar diffusion method. Compounds 6a(1), 6a(3), 6b(3), and 6b(2) were found to be active against bacteria. The compounds 6a(1), 6b(3), and 6a(3) show a significant analgesic activity. Synthesized compounds also screened for anthelmintic activity against Pheretima posthuma. Compounds 6a(1), 6b(1), and 6b(3) show significant anthelmintic activity.
