Development of a series of (1-benzyl-3-(6-methoxypyrimidin-3-yl)-5-(trifluoromethoxy)-1h-indol-2-yl)methanols as selective protease activated receptor 4 (PAR4) antagonists with in vivo utility and activity against γ-thrombin

Here, we describe the development of a series of highly selective PAR4 antagonists with nanomolar potency and selectivity versus PARI, derived from the indole-based 3. Of these, 9j (PAR4 IC50 = 445 nM, PARI response IC50 > 30 μM) and lOh (PAR4 IC50 = 179 nM, PARI response IC50 > 30 μM) maintained an overall favorable in vitro DMPK profile, encouraging rat/mouse in vivo pharmacokinetics (PK) and activity against γ-thrombin.
Synthesis method for preparing 2-substituted indole derivative
-
Paragraph 0143-0146, (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.

Pd-catalyzed α-arylation of methyl-OBO-ketone (OBO = 4-methyl-2,6,7-trioxabicyclo[2.2.2]octan-1-yl) gives rise to arylated OBO-protected pyruvates. By appropriate prefunctionalization of the aryl ring or by subsequent functionalization at the α-carbonyl p
