ido-1-in-5

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).

IDO-IN-5 is an indoleamine 2,3-dioxygenase (IDO) inhibitor (IC50: 1-10 μM).

Coptisine (Coptisin) 是一种从黄连中分离到的生物碱，是非竞争性的IDO 抑制剂，Ki=为 5.8 μM，IC50=6.3 μM。
