摘要:
Tetrahydrobenzimidazole derivatives represented by formula (I) : wherein Het represents a heterocyclic group which may be substituted with 1 to 3 substituents selected from the group consisting of a lower alkyl group, a lower alkenyl group, a lower alkynyl group, a cycloalkyl-lower alkyl group, an aralkyl group, a lower alkoxy group, a nitro group, a hydroxyl group, a lower alkoxycarbonyl group, and a halogen atom; and X represents a single bond or -NH- which is bonded to a carbon atom or nitrogen atom of the heterocyclic ring, and pharmaceutically acceptable salts thereof. These compounds exhibit antagonism against 5-HT₃ receptor.
摘要:
4,5,6,7-Tetrahydrobenzimidazole derivatives (I) and salts thereof show 5-HT₃ antagonizing activity wherein R¹, R², R³ independently represent hydrogen atom, hydroxy group, a halogen atom, a lower alkyl group which may optionally be substituted with a halogen atom, a lower alkoxy group, a lower alkylthio group, an aralkyloxy group, an aryloxy group, a lower alkanoyl group, carboxy group, a lower alkoxycarbonyl group or nitro group; R⁴,R⁵ and R⁶ can each be a hydrogen atom or a lower alkyl group; and X is an oxygen atom or sulfur atom.
摘要:
(Biphenyl-2-ylcarboxamide)benzoic acid is useful on an intermediate for the synthesis of condensed benzazepine derivatives which are arginine vasopressin antagonists.
摘要:
Oxazinobenzazole derivatives represented by the following general formula and salts thereof: wherein R 1 , R 2 , R 3 and R 9 are the same or different and selected from hydrogen atoms and C 1 -C 6 alkyl groups ; R 5 and R 6 form, in conjunction with the two adjacent carbon atoms, a 5- or 6-membered heterocyclic ring having at least two nitrogen atoms and optionally a further heteroatom selected from oxygen, sulphur and nitrogen ; and m is 0 or 1. The compounds are useful as antispasmodic medicaments.
