Antagonists of the human CCR5 receptor as anti-HIV-1 agents. Part 1: Discovery and initial structure-activity relationships for 1-amino-2-phenyl-4-(piperidin-1-yl) butanes

Screening of the Merck sample collection for compounds with CCR5 receptor binding afforded (2S)-2-(3,4-dichlorophenyl)-1-[N-(methyl)-N-(phenylsulfonyl)amino]-4-[spiro(2 ,3-dihydrobenzthiophene-3,4′-piperidin-1′-yl)]butane S-oxide (4) as a potent lead structure having an IC50 binding affinity of 35 nM. Herein, we describe the discovery of this lead structure and our initial structure-activity relationship studies directed toward the requirement for and optimization of the 1-amino fragment.

Quaternary ammonium compounds as tachykinin antagonists

The present invention provides a compound of formula (I) wherein R is phenyl, C3-C7cycloalkyl or heteroaryl, each of which being optionally benzo- or C3-C7cycloalkyl-fused and optionally substituted, including in the benzo- or C3-C7cycloalkyl-fused portion, by from 1 to 3 substituents each independently selected from C1-C4alkyl, fluoro(C1-C4)alkyl, C1-C4alkoxy, fluoro(C1-C4)alkoxy, phenoxy, C2-C4alkanoyl, halo, C1-C4alkoxycarbonyl, C3-C7cycloalkyl, —S(O)m(C1-C4alkyl), cyano, —NR2R3, —S(O)mNR2R3, —NR4(C1-C4alkanoyl) and —CONR2R3, or R is 2,3-dihydrobenzo[b]furanyl or chromanyl; R1is H or C1-C6alkyl; W is a direct link, methylene or ethylene; X is unbranched C2-C4alkylene; Y is phenyl, naphthyl, benzyl, pyridyl, thienyl or C3-C7cycloalkyl, each of which being optionally substituted by from 1 to 3 substituents each independently selected from C1-C4alkyl, fluoro(C1-C4)alkyl, C1-C4alkoxy, fluoro(C1-C4)alkoxy, halo and cyano; Ar is phenyl, naphthyl, benzyl, thienyl, benzo[b]thienyl or indolyl, each of which being optionally substituted by from 1 to 3 substituents each independently selected from C1-C4alkyl, fluoro(C1-C4)alkyl, C1-C4alkoxy, fluoro(C1-C4)alkoxy, halo and cyano, or Ar is 1,3-benzodioxolan-4 or 5-yl or 1,4-benzodioxan-5 or 6-yl; ZAis a pharmaceutically acceptable anion; with the proviso that when W is a direct link and R is optionally fused and optionally substituted heteroaryl, said heteroaryl is linked by a ring carbon atom to the carbonyl group. The compounds are tachykinin antagonists.
