  • IMMUNOSUPPRESSIVE LEUKOCYTE ADSORPTION MATERIAL AND ADSORPTION COLUMN
    Publication number: 20200215253
    Abstract: An objective of the present disclosure is to provide an adsorption material that can selectively adsorb immunosuppressive leukocyte. The present disclosure provides an adsorption material for immunosuppressive leukocyte. The adsorption material includes a water-insoluble carrier to which at least one nitrogen-containing compound selected from a polyamine represented by a predetermined formula and aliphatic amines represented by predetermined formulae are bound. A form of the water-insoluble carrier is a fiber or a particle, a diameter of the fiber or the particle is 15 to 50 ?m, and an arithmetic mean roughness of a surface of the water-insoluble carrier is 0.1 to 3.0 ?m.

  • Urea derivative and use therefor
    Patent number: 10280145
    Abstract: A compound has inhibitory activity on Discoidin Domain Receptor 1. A urea derivative is represented by the formula (I) or a pharmaceutically acceptable salt thereof: wherein, R1 is trifluoromethyl, trifluoromethoxy, or pentafluorosulfanyl; each R2 is independently a hydrogen atom or methyl which is optionally substituted by one hydroxyl or one saturated heterocyclyl having four to six ring-forming atoms; R3 is a hydrogen atom, halogen atom, C1-C3 alkyl, saturated heterocyclyl having four to six ring-forming atoms and optionally having an oxo group, or R5O—; and R4 is phenyl, pyridyl, pyridazinyl, or pyrimidinyl, which phenyl, pyridyl, pyridazinyl, or pyrimidinyl is optionally substituted by one R6.
