Title:
AGENT FOR SUPPRESSING IL-31 PRODUCTION AND PHARMACEUTICAL COMPOSITION CONTAINING THE SAME
Document Type and Number:
WIPO Patent Application WO/2022/168962
Kind Code:
A1
Abstract:
The present invention provides an agent for suppressing interleukin 31 (IL-31) production and a pharmaceutical composition containing the same. The present invention also provides a novel compound that is effective as an active ingredient of the agent for suppressing IL-31 production. These contain a compound represented by formula (1) or a salt thereof as an active ingredient. (In formula (1): A is a -NH-N=C (R1)- group, a divalent nitrogen-containing 5-membered heterocyclic group, or a -NH-CO- group; the R1 is a hydrogen atom or a C1-4 alkyl group; B is the same or different, is a C1-6 alkyl group that may have one hydroxyl group, a mono- or di-(C1-6 alkyl) amino group that may have one hydroxyl group, a halogen atom, a halo C1-6 alkyl group, a C2-6 alkynylene group, or a carboxy group; the C1-6 alkyl group of the mono- or di-(C1-6 alkyl)-amino group may bond to a carbon atom adjacent to the carbon atom of the phenyl group to which it is bonded to form a 5 to 6-membered ring; and n is an integer between1 and 5.)
