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).

Cycloalkylmethyl Radicals. Part 8. A Conformational Study of Dioxa- and Dithia-cyclohexylmethyl Radicals by EPR Spectroscopy

The conformations of some six-membered oxygen- and sulphur-containing heterocyclic rings have been investigated by EPR spectroscopy using the methylenyl group, CH2., directly attached to a ring carbon atom as a 'spin probe'.For the 2-oxacyclohexylmethyl radical the CH2. group has a 'conformational free energy' preference for the equatorial position, -ΔG0273 = 1.4 kcal mol-1, which is about twice as large as the 0.7 kcal mol-1 found previously for cyclohexylmethyl.The equatorial preference of the CH2. group is still greater in (1,3-dioxan-2-yl)methylradicals; indeed, even with the cis-(5-tert-butyl-1,3-dioxan-2-yl)methyl radical the CH2. group was equatorial and the tert-butyl group axial.The CH2. group in (1,3-dioxan-5-yl)methyl also exhibits a strong preference for the equatorial position (ΔG0 > ca. 1.5 kcal mol-1), but with cis-(2-methyl-1,3-dioxan-5-yl)methyl it is the methyl group which is equatorial and the CH2. group axial.These and other axial/equatorial conformational preferences and the rotational conformational preference of the plane of the CH2. group with respect to the Cβ-Hβ bond are rationalized in terms of subtle steric factors which involve 1,3-axial/axial interactions, or lack thereof, and the variation in the lengths of C-C, C-O and C-S bonds.
