    • A synthetic substrate used for quantitative analysis of a trace enzyme. The substrate has a molecular structure (B)-(A)-(C) comprising at least one structure (A) catalytically affected by the enzyme to be analysed, at least one photographically active labelling structure (B) linked to the structure (A) and at least one specific adsorbing structure (C) linked to the structure (A). The substrate is used in a quantitative analysis of a trace enzyme, in which the structure (A) or the linkage between the structure (A) and the structure (C), or the linkage between the structure (B) and the structure (A) is cleaved by the action of the analyte enzyme. The reaction product of the enzymatic reaction is separated by allowing the same to contact with an adsorbent for the structure (C). The separated reaction product is developed photographically and then the optical density of the resultant developed silver and/or colored dye is measured.

    • Disclosed is a method of preparing a thiohydrazide product compound from a hydrazide starting compound. The hydrazide starting compound is represented by Structural Formula (I): The thiohydrazide product compound is represented by Structural Formula (II): In Structural Formulas (I)-(II), R1 and R2 are independently an aliphatic group, a substituted aliphatic group, an aryl group or a substituted aryl group, or R1 and R2 taken together with the carbon and nitrogen atoms to which they are bonded, form a non-aromatic heterocyclic ring optionally fused to an aromatic ring. When R2 is an aryl group or a substituted aryl group, then R5 is a hydrazine protecting group; and when R2 is an aliphatic or substituted aliphatic group, then R5 is —H or a hydrazine protecting group. R10 is —H or a substituted or unsubstituted alkyl group. The method comprising the step of reacting the starting compound with a thionylating reagent.
