ido1 in 5

(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).

LY3381916 is a selective, potent and brain penetrated inhibitor of IDO1 activity, binds to apo-IDO1 lacking heme rather than mature heme-bound IDO1.

PROTAC IDO1 Degrader-1, a pioneering compound, efficiently targets indoleamine 2,3-dioxygenase 1 (IDO1) for ubiquitination and degradation by recruiting IDO1 to the CRBN E3 ligase, thereby facilitating its entry into the ubiquitin-proteasome system (UPS) with a DC50 of 2.84 μM. This compound also moderately enhances the tumor-killing efficacy of HER2 CAR-T cells[1].
