  • Title: Synthesis and biological evaluation of 3,4-diaryl-5-aminoisoxazole derivatives.
    Author: Liu T, Dong X, Xue N, Wu R, He Q, Yang B, Hu Y.
    Journal: Bioorg Med Chem; 2009 Sep 01; 17(17):6279-85. PubMed ID: 19665898.
    Abstract:
    A series of cis-restricted 3,4-diaryl-5-aminoisoxazoles have been synthesized and evaluated for their biological activities. Among them, compound 11a and 13a displayed potent cytotoxic activities in vitro against five human cancer cell lines with IC(50) values in the low micromolar range and two compounds inhibited tubulin polymerization with IC(50) value of 1.8, and 2.1 microM, respectively, similar to that of CA-4. Compound 13a could arrest at the G2/M phase of the cell cycle at the concentration of 0.1 and 1.0 microM and induce apoptosis at 0.1-1.0 microM.
