  • Publication number: 20200243166
    Abstract: Provided are a feature quantity calculating method, a feature quantity calculating program, and a feature quantity calculating device which enable calculation of a feature quantity accurately showing chemical properties of a target structure, a screening method, a screening program, and a screening device which enable efficient screening of a pharmaceutical candidate compound using a feature quantity, and a compound creating method, a compound creating program, and a compound creating device which enable efficient creation of a three-dimensional structure of a pharmaceutical candidate compound using a feature quantity. Since the chemical properties of the target structures are exhibited as the result of an interaction between the target structure and a probe in the periphery thereof, the fact that the degree of accumulation (feature quantity) of probes is similar between target structures indicates that the chemical properties of the target structures are similar.

  • Patent number: 10241400
    Abstract: A color developing composition which develops colors in a high density and does not significantly discolor when aged, a lithographic printing plate precursor which has excellent plate-inspecting properties by means of color development and is capable of maintaining strong color development even when aged after color development, a plate making method for a lithographic printing plate in which the lithographic printing plate precursor is used, and a new compound that can be preferably used as a color developer. The color developing composition of the present invention includes a compound represented by Formula 1. The compound in the present invention is represented by Formula 1. In Formula 1, R1 represents a group in which an R1—O bond is cleaved by heat or exposure to infrared rays.

  • Patent number: 8957140
    Abstract: To provide a novel triazine-based compound exhibiting an ultraviolet blocking effect even in the long-wavelength region and being useful as an ultraviolet absorber with excellent light resistance, and to provide an ultraviolet absorber and a resin composition, which can maintain a long-wavelength ultraviolet-blocking effect for a long period of time. A compound represented by the following formula (1): wherein each of R1a, R1b, R1c, R1d and R1e independently represents a hydrogen atom or a monovalent substituent excluding OH, provided that at least one substituent represents a substituent having a Hammett's ?p value of 0.3 or more and substituents may combine with each other to form a ring, and each of R1g, R1h, R1i, R1j, R1k, R1m, R1n and R1p independently represents a hydrogen atom or a monovalent substituent, provided that substituents may combine with each other to form a ring.

  • Publication number: 20140229150
    Abstract: A simulation apparatus, including: a coordinate setting unit for setting slow coordinates and fast coordinates based on mass point coordinates; a coordinate extraction unit for obtaining a structure of the fast coordinates by subordinating the fast coordinates to the slow coordinates and obtaining, by taking into account influence of a change in the fast coordinates on the slow coordinates due to a change in the slow coordinates, a structure of the slow coordinates as a function of collective coordinate(s); and an inverse transformation unit for predicting time evolution of the mass point coordinates based on the collective coordinate(s), which can be obtained as a solution of a motion equation, structure of the slow coordinates, and structure of the fast coordinates.
