The present invention provides a compound that is highly safe and useful in the prevention, alleviation, and/or treatment of various diseases involving enteropeptidase inhibition and/or trypsin inhibition, a pharmaceutical composition containing the compound, a method for producing the compound, and the like. Specifically, the present invention provides a compound represented by the following general formula (I): [wherein: Aand Aeach independently represent an inhibitor residue having at least one activity selected from an enteropeptidase inhibitory activity and a trypsin inhibitory activity; and Z represents a spacer that links Ato A] or a pharmaceutically acceptable salt thereof.

Double-headed protease inhibitor

Methods of producing a compound represented by formula (I) or a pharmacologically acceptable salt thereof include: wherein Lis an optionally substituted Calkylene group or the like, Lis a single bond or the like, Lis a single bond or the like, R, R, and Rare each independently an optionally substituted Calkyl group or the like, Ris a hydrogen atom or the like, and Ris a hydrogen atom or the like.

Substituted dihydropyrrolopyrazole compound

The present invention provides a compound represented by the general formula (Ia) or a pharmacologically acceptable salt thereof. In the general formula (Ia), two R moieties each independently represent a Calkyl group or the like; and R, Rand Reach independently represent an optionally substituted linear or branched Calkyl group. 

Substituted dihydropyrrolopyrazole derivative

Provided is a compound represented by formula (I) or a pharmacologically acceptable salt thereof: wherein Lis an optionally substituted Calkylene group or the like, Lis a single bond or the like, Lis a single bond or the like, R, R, and Rare each independently an optionally substituted Calkyl group or the like, Ris a hydrogen atom or the like, and Ris a hydrogen atom or the like.
