  Dual neurokinin NK1/NK2 antagonists: N-[(R,R)-(E)-1-arylmethyl-3-(2-oxo-azepan-3-yl)carbamoyl]allyl-N-methyl-3,5-bis(trifluoromethyl)benzamides and 3-[N′-3,5-bis(trifluoromethyl)benzoyl-N-arylmethyl-N′-methylhydrazino]-N-[(R)-2-oxo-azepan-3-yl]propionamides

  摘要：

  Based on the structure of N-[(R,R)-(E)-1-(4-chlorobenzyl)- 3-(2-oxoazepan-3-yl)carbamoyl]allyl-N-methyl-3,5-bis(trifluoromethyl)benzamide (1), attempts to improve the NK2 affinity have resulted in the discovery of N-[(R,R)-(E)-1-(3,4-dichlorobenzyl)-3-(2-oxoazepan-3- yl)carbamoyl]allyl-N-methyl-3,5-bis(trifluoromethyl)benzamide (9, DNK333) exhibiting a 5-fold improved affinity to the NK2 receptor in comparison to 1. Simplification of the structure via elimination of a chiral centre led to 3-[N'-3,5-bis(trifluoromethyl)benzoyl-N-(3,4-dichlorobenzyl)-N'-methylhydrazino]-N-[(R)-2-oxo-azepan-3-yl]propionamide (22), a potent and fairly balanced NK1/NK2 antagonist.

  In a program aimed at the development of neurokinin antagonists, N- [(R,R)-(E)-1-(3,4-dichlorobenzyl)-3-(2-oxoazepan-3-yl)carbamoyl]allyl-N-methyl-3,5-bis(trifluoromethyl)benzamide (1, DNK333) has been discovered as a potent and balanced neurokinin (tachykinin) NK1/NK2 receptor antagonist. Enantiomerically pure (>99.5% ee) 1 can be prepared in 6 + 1 synthetic steps starting from commercially available optically active BOC-D-3,4-dichlorophenylalanine in an overall yield of ca. 25-30%. 1 showed potent affinities to cloned human NK1 (pK(i) = 8.38) and NK2 (pK(i) = 8.02) receptors. When 1 was compared to the other possible three diastereoisomers, it could be demonstrated that only the R,R-isomer (1) exhibits potent and balanced affinity for the cloned human NK1 and NK2 receptors. 1 exhibited favorable pharmacokinetic properties in guinea pigs following oral administration and demonstrated in vivo activity in pharmacological models of substance P- and neurokinin A (NKA)-induced bronchoconstriction in guinea pigs after intravenous and in squirrel monkeys after oral application.
