, p. 10859 - 10867 (2019/07/15)
Interaction of Michler's ketone-benzimidazole derivatives (MK-1 and MK-2) with serum albumin proteins was examined by absorption, steady-state, time-resolved fluorescence, molecular docking and circular dichroism methods. In the presence of albumins, a re

A compound represented by the following general formula (I), wherein ring A and ring B each independently represent a benzene, naphthalene, or heterocyclic ring which may be substituted; R1 and R2 each independently represent an alkyl group having 1 to 8 carbon atoms which may be substituted; R1 and R2 may be linked together to form a ring; a methylene group of the alkyl group having 1 to 8 carbon atoms may be replaced by -O- or -CH=CH-; Anq- represents a q-valent anion, where q is 1 or 2; p represents a coefficient to keep the charge neutral.

A leuco dye of the formula (I): STR1 wherein R1, R2, R3, R4, R5, R6, R7, and R8 each represent a lower alkyl group; A represents STR2 in which R9 and R10 each represent hydrogen, provided that both R9 and R10 may not be hydrogen, --CN or --COR14 in which R14 represents a phenyl group which is unsubstituted or is substituted by an alkyl group having 1 to 4 carbon atoms, an alkoxyl group having 1 to 4 carbon atoms, or a halogen, a naphthyl group which is unsubstituted or is substituted by an alkyl group having 1 to 4 carbon atoms, an alkoxyl group having 1 to 4 carbon atoms or a halogen, or a lower alkoxyl group, STR3 in which STR4 represents a phenyl group or a naphthyl group, R11 represents hydrogen, a lower alkyl group, a halogen, an amino group, which is unsubstituted or is substituted by an alkyl group having 1 to 4 carbon atoms, or a nitro group, or STR5 in which R12 represents a lower alkyl group, or STR6 in which R13 represents hydrogen, a lower alkyl group, a halogen, a hydroxyl group, a trifluoromethyl group, a nitro group, an amino group which is unsubstituted or is substituted by an alkyl group having 1 to 4 carbon atoms, or amide group. These dyes absorb in the near-infrared region and yields colored images with a color developer therefor with excellent preservability.
