A series of N-methylbenzamide analogues (2-18) that is structurally derived from SR 48,968, a potent neurokinin-2 (NK2) receptor antagonist (pKb 9.1), has been obtained using asymmetric synthesis. Isothiocyanato-N-methylbenzamide (10-12) and bromoacetamido-N-methylbenzamide derivatives (16-18) have been designed to serve as potential electrophilic affinity labels. Nitro-N-methylbenzamide (4-6) and acetamido-N-methylbenzamide (13-15) were designed to serve as the nonelectrophilic controls for these ligands. Functional assay results using guinea pig trachea indicate that electrophilic N-methylbenzamide analogues exhibit potent but surmountable NK2 receptor antagonist activity. Several members of this series (2, 3, 7-9) exhibit potent NK2 receptor antagonist potencies with pK b values in the range of 9.1-9.7. para-Fluoro substituted analogue 3 was found to be highly potent with a pKb of 9.7.

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.

(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).
