A novel benzoazepinequnoline (BAQ) series was discovered as RSV fusion inhibitors. BAQ series originated from compound 2, a hit from similarity-based virtual screening. In SAR exploration, benzoazepine allowed modifications in the head moiety. Benzylic sulfonyl on benzoazepine and 6-Me on quinoline were crucial for good anti-RSV activity. Although the basic amine in the head portion was crucial for anti-RSV activity, the attenuated basicity was required to reduce Vss. Introducing oxetane to the head portion led to discovery of compound 1, which demonstrated single-digit nM anti-RSV activity against different RSV strains, reasonable oral exposure in plasma, and 78-fold higher exposure in lung. Compound 1 also displayed 1 log viral reduction in a female BALB/c mice RSV model by b.i.d. oral dosing at 12.5 mg/kg. A single resistant mutant at L138F in fusion protein proved compound 1 to be a RSV fusion inhibitor.

In the search for potent and selective inhibitors of the enzyme phenylethanolamine N-methyltransferase (PNMT; EC 2.1.1.28), we examined the effect of ring size or an additional heteroatom in the conformationally- restricted benzylamine-type PNMT inhibitors. Based on semiempirical calculations (MNDO) and molecular modeling studies, PNMT-inhibitory activity of these compounds seemed to be dependent on (a) the torsion angle between the plane of the aromatic ring and the endo N atom lone pair (τ2 angle), with the optimal value of τ2 being about -75°, and (b) the amount of steric bulk about the 3-position of 1,2,3,4-tetrahydroisoquinoline (5, THIQ). 2,3,4,5-Tetrahydro-1H-2-benzazepine (6) was found to have the highest selectivity (PNMT K(i) = 3.34 μM, α2 K(i) = 11 μM, selectivity = 3.2) as compared to other homologues of THIQ (PNMT K(i) = 9.67 μM, α2 K(i) = 0.35 μM, selectivity = 0.036). The higher PNMT-inhibitory activity of 6 was attributed to favorable steric interactions of the puckered methylene groups in the putative bioactive conformation of 6 at the PNMT active site, whereas unfavorable interactions of these puckered methylene groups at the α2- adrenoceptor were thought to be the cause of reduced α2 affinity of 6. No further enhancement of the selectivity of the benzazepine ring system could be obtained via introduction of a second heteroatom (N, O, S) at the 5- position in this ring system.
