  • Patent number: 6818764
    Abstract: A method of manufacturing substance GM-95 having general formula [I], comprising (a) deprotecting a macrocyclic compound having general formula [II] (wherein, R1's are the same or different and each represents a lower alkyl group, and R2 represents a thiol protecting group) by removing acetal protecting groups (the R1's) thereof, and forming an oxazole ring through an intramolecular cyclization reaction between produced formyl group and an amide group, and (b) deprotecting a resulting macrocyclic compound having general formula [III] (wherein, R2 is as mentioned above) by removing the thiol protecting group (R2) thereof, and forming a thiazoline ring through an intramolecular cyclization reaction between a thiol group thus produced and an amide group.

  • Patent number: 6803911
    Abstract: At respective positions spaced from each other on an optic axis of illumination light, a plurality of polygons, each of which corresponds to the shape of a transverse cross section at each position of a virtual region gradually expanded as the illumination light advances from a light source 1 in an optic axis direction are disposed so that the normal of each polygon orients toward a view point in a virtual three-dimensional space. The position of each polygon on the optic axis is set so that at least adjacent polygons are partially superimposed. A texture expressing divergence of illumination light is mapped to each polygon. The size in a direction orthogonal to the optic axis of a virtual region is changed based on a distance from the view point to the light source. The magnification of the virtual region to the distance from the light source is differentiated based on a relationship between an optic axis direction and a direction in which the light source is viewed from the view point.
