Abstract: The present invention relates to a compound represented by the following formula, a pharmacologically acceptable salt thereof, or a use thereof as a pharmaceutical: wherein R1 and R2 are substituents adjacent to each other, and together with two carbon atoms to each of which they attach, form a 5- to 7-membered non-aromatic carbocyclic group or the like, which may be substituted by 1 to 4 substituents selected from (1) an oxo group, (2) a hydroxyl group, and the like; R3 represents a hydrogen atom or the like; and R6 represents a hydrogen atom or the like. This compound has a superior strength of binding to a 5-HT1A receptor and an antagonism to the receptor, and is useful as an agent for treating or preventing lower urinary tract symptoms, and particularly symptoms regarding urinary storage.

Abstract: The present invention provides a compound represented by the formula (1) or a pharmacologically acceptable salt thereof, or a hydrate thereof (provided that a compound in which all of R4a, R4b, and R4c are hydrogen atoms is excluded.): [wherein R1 represents a hydrogen atom, R2 represents a hydrogen atom, R3 represents the formula: wherein R4a, R4b, and R4c are the same as or different from each other and each represents a hydrogen atom, a C1-6 alkyl group or a C1-6 alkoxy group, etc.
