title: The synthesis and evaluation of cyclic ureas as HIV protease inhibitors: modifications of the P1/P1' residues.
abstract: Two series of cyclic ureas modified at the P1/P1' residue were prepared and evaluated for HIV protease inhibition and whole cell antiviral activity. Compounds 8b, 10 (3- and 4-pyridylmethyl analogs) and 6b (4-methoxy analog) showed significant improvement in antiviral activity relative to lead compounds DMP323 and DMP 450.
