γ-Butyrobetaine hydroxylase (BBOX) catalyzes the conversion of gamma butyrobetaine (GBB) to l-carnitine, which is involved in the generation of metabolic energy from long-chain fatty acids. BBOX inhibitor 3-(1,1,1-trimethylhydrazin-1-ium-2-yl)propanoate (mildronate), which is an approved, clinically used cardioprotective drug, is a relatively poor BBOX inhibitor and requires high daily doses.

Objects are to provide an infrared-sensitive color developing composition which develops colors in a high density by means of infrared exposure and does not significantly discolor when aged, to provide a lithographic printing plate precursor which has extremely excellent plate-inspecting properties and favorable storage stability and is capable of maintaining favorable color-developing properties and a plate making method for a lithographic printing plate in which the lithographic printing plate precursor is used, and to provide a new compound that can be preferably used as an infrared-sensitive color developer.
An infrared-sensitive color developing composition of the present invention includes a compound represented by Formula (1) (Component A). In addition, the compound in the present invention is represented by Formula (1).
A method of preparing 4-aminodiphylamine through an intermediate preparation of 4-nitrodiphenylamine and/or 4-nitrosodiphenylamine and/or their salts by reaction of aniline with nitobenzene in a liquid medium at a temperature of 50 to 130° C., under normal or reduced pressure, in an inert atmosphere or in the presence of air oxygen, with subsequent hydrogenation of an intermediate of 4-nitrodiphenlyamine and/or nitrosodiphenylamine and side products, and by isolation of 4-aminodiphenylamine and the side products of unconverted raw materials
