- Design, synthesis, and optimization of balanced dual NK1/NK 3 receptor antagonists
-
In connection with a program directed at potent and balanced dual NK 1/NK3 receptor ligands, a focused exploration of an original class of peptidomimetic derivatives was performed. The rational design and molecular hybridization of a novel phenylalanine core series was achieved to maximize the in vitro affinity and antagonism at both human NK1 and NK3 receptors. This study led to the identification of a new potent dual NK1/NK3 antagonist with pKi values of 8.6 and 8.1, respectively.

- Antagonists of the human CCR5 receptor as anti-HIV-1 agents. Part 2: Structure-activity relationships for substituted 2-aryl-1-[N-(methyl)-N-(phenylsulfonyl)amino]-4-(piperidin-1-yl)butanes
-
(2S)-2-(3,4-Dichlorophenyl)-1-[N-(methyl)-N-(phenylsulfonyl)amino]-4-[spiro(2 ,3-dihydrobenzthiophene-3,4′-piperidin-1′yl)]butane S-oxide (3) has been identified as a potent CCR5 antagonist lead structure having an IC50 = 35 nM. Herein, we describe the structure-activity relationship studies directed toward the requirement for and optimization of the C-2 phenyl fragment. The phenyl was found to be important for CCR5 antagonism and substitution was limited to small moieties at the 3-position (13 and 16: X = H, 3-F, 3-Cl, 3-Me).
