Synthesis method for preparing 2-substituted indole derivative
-
Paragraph 0199-0202, (2019/05/28)
The invention relates to a synthesis method for preparing a 2-substituted indole derivative. The method includes the following steps: mixing aromatic amine compounds (I), ketone compounds (II) and a drying agent in an organic solvent; adding a palladium catalyst; and reacting in an aerobic weak acid environment to prepare the indole compounds (III). (I), (II) and (III) are as shown in the specification, wherein R1 is selected from hydrogen, C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkanoyl, C2-C6 alkenyl, C2-C6 alkynyl, halogen, hydroxyl, substituted or unsubstituted amino, substituted or unsubstituted phenyl, pyridyl and heterocyclic aryl; (I) can be pyridylamine, pyrimidylamine, pyridazinam or pyrazinamide which may further be substituted or unsubstituted; and the substituents are selected fromone or more C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkanoyl, C2-C6 alkenyl, C2-C6 alkynyl, halogen, hydroxyl, amino; and R2 is selected from C1-C6 alkyl, formate groups or C1-C6 alkylamide groups.

Indoleamine 2,3-dioxygenase (IDO) is a heme dioxygenase which has been shown to be involved in the pathological immune escape of diseases such as cancer. The synthesis and structure-activity relationships (SAR) of a novel series of IDO inhibitors based on the indol-2-yl ethanone scaffold is described. In vitro and in vivo biological activities have been evaluated, leading to compounds with IC50 values in the micromolar range in both tests. Introduction of small substituents in the 5- and 6-positions of the indole ring, indole N-methylation and variations of the aromatic side chain are all well tolerated. An iron coordinating group on the linker is a prerequisite for biological activity, thus corroborating the virtual screening results.
