  • Patent number: 11746202
    Abstract: Provided is a method for modifying a polypropylene resin molded body with a side chain crystalline block copolymer having a long alkane chain in a side chain, having a good interaction force with the polypropylene resin molded body, and having a function capable of modifying surface characteristics. Also provided is a modified polypropylene resin molded body. The method for modifying a polypropylene resin molded body includes a step of contacting a copolymer solution including a side chain crystalline block copolymer with a polypropylene resin molded body at a temperature of the copolymer solution of 40 to 120° C. The modified polypropylene resin molded body includes a base material of the polypropylene resin molded body and a site that includes the side chain crystalline block copolymer in at least part of the base material.

  • Publication number: 20230002395
    Abstract: The purpose of the present invention is to provide a compound having M3 PAM activity. Examples of the present invention include azabenzimidazole compounds represented by the following formula [1] and pharmaceutically acceptable salts thereof. The compounds of the present invention have M3 PAM activity. In addition, since the compounds of the present invention have M3 PAM activity, the compounds of the present invention are useful as preventive agents or therapeutic agents for urination disorders and urine collection disorders in underactive bladder, hypotonic bladder, acontractile bladder, detrusor underactivity, and neurogenic bladder.

  • Publication number: 20210371412
    Abstract: The purpose of the present invention is to provide compounds having an M3 PAM action. Examples of the present invention include azabenzimidazole compounds represented, for example, by formula [I], and pharmacologically acceptable salts thereof. These compounds have M3 PAM activity. In addition, because these compounds have M3 PAM activity, these compounds are useful as agents for the prevention or treatment of voiding and/or storage disorders in underactive bladder, hypotonic bladder, acontractile bladder, detrusor underactivity, and neurogenic bladder.
