    摘要:
    A series of 3-phenyl-3H-quinazolin-4-ones have been synthesized and tested for affinity and activity at the chemokine CXCR3 receptor. The most potent compound (1d) has been evaluated using radioligand binding and calcium mobilization assays and is considered a useful tool for further characterization of the CXCR3 receptor.

    and elegant method for benzylic activation was demonstrated employing the potassium iodide/tert-butyl hydrogen peroxide catalytic system. This methodology was further extended for the synthesis of biologically important heterocycles namely, 3H-quinazolin-4-ones and 4H-3,1-benzoxazin-4-ones including mecloqualone and etaqualone which are important quinazolinone-based drugs used for the treatment of insomnia
