BILIVERDIN COMPOUND, AND PREPARATION METHOD THEREFOR AND USE THEREOF

A biliverdin compound, having a structural formula as shown in formula 1, wherein R is selected from one of hydrogen, C1-C5 alkyl, and benzyl. Formula II represents a double bond or a single bond, and said formulas II in positions A and B are independently selected from one of a single bond and a double bond, respectively; when formula II is a single bond, R1 or R2 connected to the single bond is selected from the group consisting of p-toluenesulfonyl, p-tolylsulfinyl, phenylsulfonyl, and phenylsulfinyl; when formula II is a double bond, R1 or R2 connected to the double bond is hydrogen. An intermediate body of a novel bilirubin or an analogue thereof can be used for preparing the bilirubin or the analogue thereof, and the preparation process is simple, efficient, low in cost and easy to industrialize; a preparation method for the intermediate of the novel bilirubin or the analogue thereof is simple in preparation process, and mild in conditions, can be carried out at room temperature, and is low in cost.
