- Modulation on C- and N-terminal moieties of a series of potent and selective linear tachykinin NK2 receptor antagonists
-
Herein we describe the synthesis of a series of new potent tachykinin NK2 receptor antagonists by the modulation of the Cand N-terminal moieties of ibodutant (MEN 15596, 1). The Nterminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C-terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity for the human NK2 receptor and high in vitro antagonist potency, indicating that a wide range of substituents at both termini can be incorporated in the molecule without detrimental effects on the interactions with the NK2 receptor. Selected compounds were tested in vivo confirming their activity as NK2 antagonists. In particular, after both iv and id administration to guinea pig, compound 61b was able to antagonize NK2-induced colonic contractions with a potency and duration-of-action fully comparable to the reference compound 1 (MEN 15596, ibodutant).
