  • Patent number: 11337910
    Abstract: An object of the present invention is to provide a particulate composition containing crystalline ?,?-trehalose dihydrate, having an advantageous emulsifying ability. The above object is solved by providing a particulate composition comprising crystalline ?,?-trehalose dihydrate, which consists of particles containing ?,?-trehalose and maltose and/or maltotriose, wherein said particulate composition contains ?,?-trehalose in an amount of 70% by weight or higher but 90% by weight or lower, on a dry solid basis; and maltose and/or maltotriose in a total amount of 3% by weight or higher, on a dry solid basis; and has a degree of crystallinity for crystalline ?,?-trehalose dihydrate of 25% or higher but less than 90%, when calculated based on its powder X-ray diffraction profile.

  • Publication number: 20220031690
    Abstract: The present invention addresses the problem of providing an orally-administrable anti-neurodegenerative disease agent having an action of accelerating neurocyte growth and an action of promoting neurite-outgrowth, and having excellent transfer properties to central nervous tissues. The problem is solved by providing an anti-neurodegenerative disease agent containing a compound represented by General formula 4 as an active ingredient, and having an action of accelerating neurocyte growth, an action of promoting neurite-outgrowth, and an action of scavenging reactive oxygen species. In General formula 4, R10 and R11 represent the same or different alkyl group having 2-8 carbon atoms, and the alkyl group may be either a straight chain or a branched chain. n represents an integer of 0 or 1, and X4? represents a suitable counter anion that is pharmaceutically acceptable.

  • Publication number: 20050054585
    Abstract: A process for producing a polyether polymer by polymerizing a monomer having an oxirane group in the presence of a Lewis base having no active hydrogen such as, for example, a nitrile compound, a cyclic ether compound or an ester compound; and a polyether polymer produced by this process. Thus, a polyether polymer having a minimized amount of undesirable crosslinked product can be produced without reduction of polymerization activity.
