ido1in5

LY3381916 是可透过血脑屏障的、选择性的IDO1抑制剂，能够与缺乏血红素的 apo-IDO1 结合，但无法与成熟血红素的 IDO1 结合。

(Rac)-IDO1-IN-5 is a racemate of IDO1-IN-5, a potent, selective, and brain-penetrating inhibitor of Indoleamine 2,3-Dioxygenase 1 (IDO1) activity. It specifically binds to apo-IDO1, which lacks heme, instead of mature heme-bound IDO1.

(S)-IDO1-IN-5 is an active S-isomer of IDO1-IN-5. (S)-IDO1-IN-5 binds to IDOL(IC50 value less than 1.5 µΜ).
