Cycloalkene derivatives, process for producing the same, and use

摘要

The present invention provides a prodrug of a compound represented by the formula: wherein R represents an aliphatic hydrocarbon group optionally having substituents, an aromatic hydrocarbon group optionally having substituents, a heterocyclic group optionally having substituents, a group represented by the formula: OR<1> (wherein R<1> represents a hydrogen atom or an aliphatic hydrocarbon group optionally having substituents) or a group represented by the formula: wherein R<1b> represents a hydrogen atom or an aliphatic hydrocarbon group optionally having substituents, R<1c> is, same with or different from R<1b>, a hydrogen atom or an aliphatic hydrocarbon group optionally having substituents, R<0> represents a hydrogen atom or an aliphatic hydrocarbon group, or R and R<0> represents a bond with each other, Ar represents an aromatic hydrocarbon group optionally having substituents, and n is an integer of 1 to 4, or a salt thereof, which is a agent for preventing or treating diseases such as cardiac disease, autoimmune disease, septick shock, etc..
