Human indoleamine 2,3-dioxygenase 1 (hIDO1) and tryptophan 2,3-dioxygenase (hTDO) have been closely linked to the pathogenesis of Parkinson’s disease (PD); nevertheless, development of dual hIDO1 and hTDO inhibitors to evaluate their potential efficacy against PD is still lacking. Here, we report biochemical, biophysical, and computational analyses revealing that 1H-indazole-4-amines inhibit both hIDO1 and hTDO by a mechanism involving direct coordination with the heme ferrous and ferric states. Crystal structure-guided optimization led to23, which manifested IC50values of 0.64 and 0.04 μM to hIDO1 and hTDO, respectively, and had good pharmacokinetic properties and brain penetration in mice.23showed efficacy against the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced mouse motor coordination deficits, comparable to Madopar, an anti-PD medicine. Further studies revealed that different from Madopar,23likely has specific anti-PD mechanisms involving lowering IDO1 expression, alleviating dopaminergic neurodegeneration, reducing inflammatory cytokines and quinolinic acid in mouse brain, and increasing kynurenic acid in mouse blood.

The invention discloses a preparation method of 1-Boc-3-hydroxymethyl pyrrolidine. The preparation method uses epichlorohydrin as a raw material, 3-hydroxymethyl pyrrolidine is obtained through reduction and cyclization reaction, then the 1-Boc-3-hydroxymethyl pyrrolidine is prepared through Boc protection reaction, then 1-BOC-3-methyl formate pyrrolidine is prepared through carboxylation reaction and esterification reaction, and finally the 1-BOC-3-methyl formate pyrrolidine and lithium aluminum hydride are catalyzed by a catalyst to prepare the 1-BOC-3-hydroxymethyl pyrrolidine. The preparation method is high in product synthesis rate, high in product purity and low in production cost, and the raw materials are cheap and easy to obtain.
